For many of us living in New England during the first winter of oil prices above three dollars a gallon, discussions of information technology have given way to discussions of home heating technology. We’re at the beginning of an adoption curve here that will rival earlier waves of adoption — first of iron woodburning stoves, then central heating systems fueled by coal and now mostly oil.
Our future fuel is biomass, in the form of sawdust and other recycled wood waste compressed into pellets that look like rabbit food. They burn cleanly and efficiently in airtight stoves that use augurs to feed the pellets slowly and steadily from hoppers into surprisingly small combustion pots.
Like several of our friends, we jumped on the bandwagon last year. Ours is an insert that converts an otherwise useless fireplace into a heat source that’s displacing a sizable chunk of our oil usage. Another friend uses a standalone unit which, because pellet stoves produce so little exhaust heat, is vented through a wall without requiring a tall flue. Two other friends have pellet stoves in their basements, one heating a small house passively and another heating a larger house through its pre-existing forced hot air ducts.
We’re all new to this game, so when we get together we compare notes on stove designs, pellet prices and quality, heat distribution strategies, cleaning and maintenance, and of course effectiveness. Everyone’s story is different. My friends who are leveraging their pre-existing forced hot air system have just about kissed the oil truck goodbye and are saving a lot of money. But they’re not quite as comfortable upstairs in really cold weather as they used to be. Others with hot water radiator systems, including us, aren’t doing nearly that well. We’re using Rube Goldberg arrangements of fans to distribute the hot air that the stoves blow, but that only gets you so far in an old New England house with lots of small rooms. For us, it’s a supplement that’ll pay for itself in a few years, but not a replacement. And we’re way less comfortable in parts of the house than we used to be.
Still, this technology represents a path to a sustainable future in which we use a locally-produced commodity to heat our homes much more cleanly and efficiently than wood ever did before, at a cost that’s already way below oil and will only look better as oil continues to skyrocket.
For most of us, though, it’s not yet a perfect replacement. And for all of us, it’s not automatic. A truck doesn’t show up at the house to pump pellets into a giant tank. We buy them by the ton, and they’re delivered on pallets bearing fifty forty-pound bags that we haul inside, stack, and then dump one at a time into our hoppers. The reload interval varies from less than a day in our case, to up to a week in other cases. Although these stoves produce very little ash — a few ounces per 40-pound bag — the ash removal chore also varies from days to months depending on the design of your stove. In terms of convenience, heating with pellets is more like heating with wood than heating with oil or gas. There’s hauling, there’s loading, and there’s maintenance.
But things will change. A home like mine, with an oil burner and hot water circulating through radiators, will use a boiler that heats the water with pellets instead of oil. These are emerging in Europe, but only starting to come onto the market here. I don’t know anyone who uses one to heat a private residence. But the Harris Center — a nature conservancy in the nearby town of Hancock — is heating 10,000 square feet for $1700/year using a pellet boiler. I was driving by Hancock today and stopped to take a look. The place was closed, but I saw the silo that stores and automatically delivers pellets. For the oil tanks in basements like mine, that’s the handwriting on the wall.

As a fellow New Englander we’ve considered alternatives to fuel oil, but we’ve stuck with oil for now.
Today you have to be a bit of a commodities trader to heat your home.
One way we’ve protected our cash flow is to spread out payments for oil in a 10-month budget plan - and we’ve used futures contracts as a hedge against oil cost surges. Most carriers allow consumers to pre-buy oil during the summer. They either store the oil for you or purchase a commodities contract on your behalf that guarantees the oil at a preset price (typically higher than the summer price but lower than the winter high). Usually pre-buys means just that - you must purchase all oil in advance. That’s difficult for most of us.
The vendor we use offers a pre-buy but allows you to spread the cost across 10 monthly budget payments. In this way we hedge against inflation and maintain manageable bills (A $3.129 per gallon fillup when you have two 275 gallon tanks is a killer).
For us, it’s all about cash flow. We considered adding 12 inches of insulation in the attic, the payback in cost savings was 7 years. Right now that’s not worth it.
As for pellet stoves, you have the mess, the manual loading and the potential for auger jams that cause the unit to go out. That’s not a big deal for supplemental heating, but it’s serious business if you’re relying on it to heat your entire home.
Here’s another issue: While oil burners use oil only until the boiler is at temperature, pellet stoves must continuously maintain the firebox. So in this way, I would think that they’re more inefficient in the consumption of fuel. To the extent that some pellet stoves burn more cleanly than oil, and that the cost per BTU for wood pellets exceeds that of oil burners that makes it attractive.
If everyone in New England started using pellet stoves I suspect that we’d begin stripping away the forests here and prices for fuel would rise (An interesting excercize would be to estimate total heating oil use in New England and calculate the packages of pellets required and by extension the number of trees that must be cut. Is that sustainable?). In that situation I wonder if pellet stoves would still offer an advantage.
December 31, 2007 at 3:58 pm
We got rid of the oil boiler…and the oil tank.
And we replaced it with a pellet boiler. It’s plugged into our existing heating system….radiators.
I fill the hopper frequently.
We installed the thing in the summer of 2007 in New Hampshire.
December 31, 2007 at 4:27 pm
“If everyone in New England started using pellet stoves I suspect that we’d begin stripping away the forests here and prices for fuel would rise”
How to manage the resource properly will surely be an issue, but it’ll be a /good/ issue to grapple with, socially and politically and economically.
“we replaced it with a pellet boiler”
I would love to find out more about your experience with it.
January 4, 2008 at 11:13 am
All the houses I lived in, in Europe, were heated by gas-powered boilers (except one which was 100% electric, horribly expensive). Not the best for sustainability, but it’s better than oil, and it reduces competition for oil anyway, which is good; I’m surprised you didn’t even mention it in your list of “waves of adoption”…?
Anyway, I agree with Robert that the issue of managing the resource WILL come up as soon as this sort of thing really goes mainstream. As long as otherwise-wasted wood is used, it’s a good solution.
January 5, 2008 at 9:37 am
I am from Indiana, grew up in Northern Indiana and we heated exclusively, and passively, with airtight wood stoves. My sister currently heats her home with an external woodburning water heater that pumps the heated fluid (an antifreeze mix, not under pressure) into their home and via a heat changer (a tube within a tube affair) their old water heater doesn’t burn gas except in the summer. Their home is heated with circulated water registers, so the heat is produced outside, transfered inside, then throughout the house via the registers. I live in Central Indiana, Indianapolis, in a subdivision, so stacking 14 rank of wood in my yard would have my neighbors using to to build my funeral pyre, so heating with wood was out of the question. The house had a wood burning fireplace, and I but a corn burning stove into it. Corn has more energy than the wood pellets, and is available here in Indiana. If it weren’t for the infernal vaulted ceilings (and I have ceiling fans throughout, but it is still a source of waste) it would be my only source of heat. I can store an entire winter of corn in my garage, and the waste ash is basically potash, a good fertilizer to put back on any corn field. When I get around to building my own home, I will build with the plan to heat with an external burner (they look like little sheds) that can burn either wood (while I am young and capable of enjoying cutting, splitting, hauling, and stacking) and corn/pellets (when I am tired of all the effort). There are burners out there that are capable of being configured to burn these different fuels reliably (I would mention a manufacturer, but I am not certain it is appropiate here, if so, let me know and I will respond with it). Corn is plentiful, energy dense, environmentally friendly and if enough people start using it as a fuel, why couldn’t we expect to see a bulk truck driving through a neighborhood filling hoppers and automatic feeder tanks? American Product, American Consumers, American Jobs, Saving the Environment? Is there any downside? Some effort I suppose, but I KNOW I don’t get enough exercise, and with a 60 bushel automated feeder, I probably still wouldn’t.
January 5, 2008 at 10:16 am
“I’m surprised you didn’t even mention it in your list of “waves of adoption”…?”
It’s a regional thing. In the midwest where I used to live, gas is locally available and a major factor. In the northeast, it isn’t locally available, so oil tends to dominate.
“Corn is plentiful, energy dense, environmentally friendly”
Yes. That’s another midwest vs northeast difference.
“American Product, American Consumers, American Jobs, Saving the Environment?”
Exactly.

Well, there are no easy answers to this one. I can tell you that I have been very happy with a wood gasification boiler, made by HS Tarm. It is probably not the most efficient of the wood gasification approaches, because it tends to run at a somewhat high stack temperature and doesn’t use as much surface area as the really sophisticated ones do for heat exchange (see the “Wood Gun”). However, I can pretty much heat my house for about four cords of wood and use the oil burner pretty much just to supplement it when I’m away or can’t get outside to use the wood. The problem of course is that it’s getting harder to get cheap cordwood in New England, and of course stacking wood, emptying the ash, filling the firebox, etc., etc., etc. can be a real pain in the butt particularly compared with just turning on the thermostat. However the savings are pretty staggering. At $180 a cord, using this compares pretty favorably to anything including even coal, and its cost per BTU is about nine dollars per million BTUs. Oil at $3.30 a gallon cruises on in at about $28 per million BTUs. Natural gas at $1.40 per therm seriously undercuts the price of oil at $17 per million BTUs but still doesn’t compare to wood. The long and the short of it is that if you don’t mind doing extra work, you can save a lot of money using a wooden gasification boiler, and still keep the convenience of central heating compared to pellet stoves. However they are not cheap, and wood gasification boilers run anywhere from six grand to 10 grand. I figure I’m saving about $2500 a year in fuel costs, so this will pay for itself in about four years.

I think you will all find this ‘quick’ analysis of wood heating illuminating:
http://www.theoildrum.com/node/3374
Home Heating in the USA: A Comparison of Forests with Fossil Fuels
“While there is seemingly a huge inventory of trees in our country, there is also a huge inventory of humans and their respective consumptive wants. Warmth and protection from cold are among the most basic of our human needs – quite simply, there are not enough trees for an annual growth harvest to provide more than a fraction of our current heating needs. I don’t really expect we will return to heating with wood, but the point of this exercise is to show that if the market should incentivize people to heat with wood, we have upper limits in expanding our use of wood for heating, and they are not too far from where we are now.”
January 13, 2008 at 9:35 am
“if the market should incentivize people to heat with wood, we have upper limits in expanding our use of wood for heating”
It’s not just wood. Pellets can come from a variety of forms of regionally-appropriate biomass. The final comment in that thread:
http://www.theoildrum.com/node/3374#comment-279722
says in part:

Pellet stoves burn a small quantity of fuel fast. The newest ones are as efficient as the highest efficiency gas stoves.
http://www.bixbyenergy.com
http://www.hinkletown.com/bixby
There are also commercial size pellet stoves made for retrofitting large buildings like schools. The stoves are placed outside and use heatexchangers to connect to the building’s present system.
REAP-Canada has been researching biomass production and conversion. They have been burning both wood and switchgrass in a pellet stove. Their EROI for switchgrass production and pelletizing in S/W Quebec is 14.6. They have an interesting Powerpoint presentation up at
http://www.reap-canada.com/online_library/Reports%20and%20Newsletters/Bioenergy...
Pelletizing of switchgrass was done at a wood pelletizing plant, but if grass pellets as heating fuel takes off, I’m sure that pelletizing will ultimately end up being done right at harvest by the same machine. Remember, the word combine comes from “combined harvester” which reaped, threshed and separated all in one pass. This is a trivial engineering problem for ag engineers and farmers.
Switching from anual grain crops to perennial biomass crops has huge positives for farmers: lower production costs, lower risk, lower capital needs, higher return. Biomass has the potential of giving a farmer three paychecks: the crop, carbon credits, wildlife habitat payments.

I purchased a pellet stove in late November. I purchased a fire place insert model and did the install myself. This included doing a reline of my chimney with help from my son. My house is about 2000 sq.feet. We have been very pleased with the performance of our stove, particularly with all of the cold weather in December and January. We keep our house temperature between 62-64(at night) and 64-68 (during the day)degrees.
As mentioned in several of the other posts, your success in heating your house depends on a number of variables, particularly the layout of your house and location of your stove. My stove is located in a central location (with a central stairwell) on the first floor of a two story and it does a great job of heating the upstairs.
My primary heat source is oil and my personal pleasure is watching my oil level just sit there! We use a little for heating hot water, but it barely has moved since December 3rd. I am on my second ton of pellets and this will get me through to the end January.
As I see it my benefits have been lower direct heating costs, a warmer house, being more environmentally friendly and doing my part to reduce dependence on foreign oil. The drawbacks include the daily grunt work of loading the stove and the every 3-4 day emptying of the ash (for my insert model) and cleaning of the stove (I have this down to 20 minutes).
Overall, I am very pleased with my decision to go to pellet heat! I recommend that you do your research and carefully consider your house layout, sq.footage, stove location and BTU requirements when thinking of going pellet.

Is a ground-source heat pump an option? They are expensive, and they require that coils be sunk into your yard. However, they use very little energy and they provide efficient cooling in the summer. Can they produce enough heat for a New England winter?
Ground source heat pumps might be too expensive to be worth it today, but I wonder if higher energy costs and economies of scale (as/if more people buy them) will push the price down enough to make them worth it.
I was also surprised that more people don’t use natural gas. From what I understand, a lot of the natural gas present at oil drilling sites just gets burned off and wasted today because there is not enough demand for it. That has always struck me as a such a waste, especially with energy becoming more and more expensive.
February 6, 2008 at 8:04 am
“Is a ground-source heat pump an option? ”
Yes. One friend is using that method successfully. Another was unable to because the well on his property doesn’t deliver enough flow — you need to move a lot of water.

Just over a year ago, 18 FEB 2007, I converted my oil burning boiler to burn wood pellets. I replaced the oil burner on the boiler with a wood pellet burner from Sweden. This approach retained my entire heating system, controls and all and was a low-impact conversion. In the past year I’ve burned over 10-tons of pellets keeping my 1400 sq foot house (built in 1910 with little insulation) warm and cozy. I’m now in the process of getting manufacturing rights to these burners and setting up to build them in New England. Even if it isn’t a huge money maker, the more people that can get off of oil and onto renewable wood pellets, the better!!!

Hi All:
This November I purchased pellet boiler and have been running ever since. I’m a plumbing and heating contractor and work with alot of alternative energy boilers. My unit is Harman pb105 boiler. It’s alot cheaper than my oil fired boiler in operating costs. Original purchase price with flue piping was $6000. I figure about three year payback. There are alot of maintenance ie cleaning and also stacking . Buying in bulk and silo storage is better than bags.
March 17, 2008 at 7:55 pm
Andy
Do you have any info on oil fired conversion to wood pellets??
March 18, 2008 at 8:39 am
I’m currently weighing two options: A pellet boiler, and a wood gasification boiler. I think the cost will be roughly equal. Likewise the environmental impact: I guess these new wood gasification boilers extract about as much heat and produce as little residue from wood as pellet stoves do from pellets.
Given that both options will require stacking and maintenance, it’s not clear that the pellet option is much more convenient.
I reckon the fuel cost is roughly the same too, but what I’m wondering is whether the future prospects for unprocessed wood may not be better than for processed pellets.
March 24, 2008 at 6:32 am
I would like info on conversion oil to pellets on my existing oil fired boiler thanks mike

Hi Folks! I just got my web site up and running, published it on Friday (28 MAR 08). If you want to see more information regarding our system for converting oil fired boilers to wood pellets, check it out: http://www.pellegy.com
We’re still a few months away from being able to ship to additional customers, but our manufacturing line is comming up and we plan on sending a couple units out for testing real soon. This will allow us to open up the market space a little more. Shoot me a note off the site’s link and we’l be sure to keep you updated on our progress.

I’m considering a pellet furnace myself. A Harman PB105. The addition of a supplemental heat source would be welcome given the cost of heating oil. Would you be willing to share more details of your experience this last winter with the pellet heat and dispense some advise?
April 14, 2008 at 9:27 pm
Michael:
Buy pellets early if you have the storage for them. If you can set up for a bulk pellet delivery it will save you a lot of money, but you need to consider storage and handling. Pellets need to stay dry. The Harman PB105 is a nice boiler, but it only has a 160 LB hopper. This means a lot of time filling. Harman also has a larger bulk bin with integral feed conveyor as an add-on to the boiler. Ask about it and see if it is right for you (size, physical footprint, cost, etc.). Back to pellets: New England Wood Pellet in Jaffrey, NH will deliver bulk pellets within a couple hundred miles of their facility. If you can handle bulk pellets and the delivery rates, this is the way to go. I had them deliver almost 7-tons of pellets last year in one drop at the rate of just about $215/ton (delivery included). This will go up as oil prices do; however, there are more places getting into the bulk pellet delivery business such as Biomass Commodities Corp out of St. Johnsbury, VT. Pellet heat is great, but it is solid fuel heating and requires more intervention than that of oil, natural gas or propane, less than cord wood. As a supplemental heat source, pellets are outstanding.
Consider about 1-ton of pellets for every 130-gallons of oil burned today. This is a very rough number, but reasonable for a back of the napkin calculation. Shoot me a note if you have more questions.

May 22, 2008 at 9:21 am
I am currently going through the process of selection of a pellet furnace to place in parallel with my oil furnace. I am considering the Harman PB105 or the pinnacle/Traeger PB150. Anyone have any information on these for comparison to the “company line” from the suppliers?? I live in a central Maine town in an older home which used 1670 gallons/year average for the past three years.

As far as oil goes, many people are trying to go green by either reducing their oil intake, or shutting it all off and freezing. But there’s actually a cool new thing called Bioheat. It still uses oil, but it is now blended with biodiesel, therefore, producing NO greenhouse gases and reducing emissions. Working for NORA, I have seen the increase in “green” needs. Check out this site for more info on bioheat. Amazing stuff.

> It still uses oil, but it is now blended

From the page you cite:
“It costs just about the same as “regular oil.””
Nonstarter for most of us. We need a fuel that’s way cheaper than oil, and that can also be burned cleanly. In New England that fuel is wood and wood products. The clean-burning technologies I’m aware of are pellet boilers and modern wood (gasification) boilers.

I am just starting to Look into the the Wood/corn
Pellet thing. I am looking for a conversion to my current OIL Drinker Boiler I also live in Vermont, In a very old Leaky House. The way Oil is Now I just cant afford to Run oil anymore
And with the projected Cost to go up to 200bucks a barrel I am just not sure what i am going to
with my Current situation. I use Oil 360 days a year I wish I had foward thinking when I instaled my Present Oil boiler 5 years ago at that time i would have gone with a pellet Boiler
May 25, 2008 at 7:48 pm
I bought the pb-105 boiler and have run it for one winter season. It has a 200lb hopper on it not 160lb and can also burn corn .Down side to corn is it is corrosive and leaves clinkers.produces more heat per pound than pellets but also have to contend rodent issues.I used pellets in mine.I had problem with igniter burning out.Its a Harman boiler. They had issues with all there stoves igniter’s. It took me 2 months to get the replacement.Harman’s attitude was just deal with it.There customer service attitude is poor.
I’m a plumbing and heating contractor and if I put in new boiler for someone and couldn’t get part for 2 months my customers would have sued me.Overall the boiler works very well but needs to be serviced and cleaned often for best results. If you want hands off heating approach then this boiler isn’t the answer. You need to be somewhat mechanically inclined. Because if you have dealer service it , it will be minimum $135 service call.
I burnt about 5 tons for 2,000 sq. ft. colonial with two zones of heat and indirect hot water tank at cost of about $1050 oil would have easily been $3500.
May 28, 2008 at 4:33 pm
We put in the Harman PB105.
In the first few months, it’s automatic igniter burned out 2 or 3 times.
The retailer replaced them without question.
Harman then sent the retailer a reconfigured burnpot with a new igniter.
The PB105 worked fine after that.
It does require some maintenance, such as cleaning the burnpot weekly.
It also requires moving bags of pellets, and lifting them to burn in the boiler.
In my mind, these are small concessions to renewable fuel and cleaner emissions.
May 28, 2008 at 8:15 pm
> In my mind, these are small concessions
> to renewable fuel and cleaner emissions.
Indeed. My order for an Orlan EKO-40 (wood gasification boiler) will be placed tomorrow. If all goes well, I’ll be loading firewood 2 or 3 times a day come next winter, and will be grateful to do it.
May 28, 2008 at 8:22 pm
you received a reconfigured burn pot on your Harman pb-105??
May 28, 2008 at 8:24 pm
when did you get the new burn pot recently???
May 29, 2008 at 1:51 pm
bryan,
Yes, we got a reconfigured burn pot.
It is similar to the original, but has fewer holes toward the narrow end.
The new one has worked well…I think we got it in January.
Your retailer should be able to get you one from Harman if you need it.

Very interesting posts. I live in Keene and when I bought my house in 2003 it had an underground oil tank. That scared me a bit and I finally had it taken out in the summer of 2006. At that time I had to decide if I wanted to buy an oil tank or go with pellets and buy a pellet stove or furnace. I went with a pellet furnace. Everything seemed great at first — it would take me about 5 minutes a day to load the hopper, do some cleaning, etc., but that seemed a very small price to pay for efficient, relatively cheap heat. Unfortunately the furnace died after something like a month (would have been around February 2007). The installers replaced a part (can’t remember what, sorry) but it died again a month later (March 2007). I was so disgusted at that point, and so busy with work, that I just used little electric heaters for the next few weeks until the heating season ended. My work schedule got crazy and I never got the furnace fixed for winter ‘07-08 - just used the heaters all over my house (a ranch of about 1,500 square feet). Surprisingly the electricity didn’t cost as much as I’d feared, but coming home to a cold house every day (I didn’t like leaving the heaters running when I wasn’t there) wasn’t much fun. I just bought 5 tons of pellets from Home Depot (great price) and am storing them in my garage, which means I’ll be going back to pellet heat for next year. Time to call the installers again. (Luckily the warranty is at least 5 years so it should be free to fix — it’s just a pain in the butt.)
Do those of you who have the pellet furnaces have any tips on maintenance? I feel like I must be doing something wrong - surely it shouldn’t have died twice in 2 months.
Also is anyone using geothermal heat? It’s not an option for me here in Keene (my lot isn’t big enough, for one thing!) but maybe for the future.

I have just finished sending out the deposit and reservation letter for a Maine Energy System Pellet Boiler. I have done as much research on pellet boilers as I can without going to Europe and going through the factories. The system put together by Maine Energy uses the oldest manufacturer of pellet burners (Janfire) in the world coupled with a Bosch boiler to create a system that needs only ash emptying 2-3 times a season and a single annual cleaning. I am ordering pellets directly from Maine Energy as well - 235/ton delivered. No oil for our family this year.
June 8, 2008 at 6:55 pm
This is really interesting discussion. I have a 3500 sq. foot four story townhouse in Massachusetts. I spent about $4500 on oil this season — I have a REALLY old oil furnace (it was originally a coal burning one) and can’t afford to double my cost of oil. I’m looking into corn pellet burner (yellowsgreen.com) but they will have to be hotwater, not my current steam, in the radiators, which will require a lot of piping. I don’t know how often I’ll have to stoke the furnace. Any ideas/suggestions? I’m also looking to convert to gas.
June 16, 2008 at 1:39 pm
We live in a 1922 New Englander with steam heat (you know those big old radiators) Oil is just about breaking us. Is there any way to put in a pellet stove in our basement with the current furnace to supplement cost. Forgive my ignorance on the matter. If that won’t work are there any other suggestions?

June 16, 2008 at 3:54 pm
Carla, others on this thread have commented on their experience with pellet boilers that can complement an oil burner in a hot-water-based heating system.
A year from now, I hope I’ll be able to comment on my own experience with the EKO wood gasification boiler that I’ve ordered but not yet installed.

I have an oil boiler which provides steam to radiators in a 1250 sqft home, 2nd floor. With the very high oil cost, I’d like to supplement the oil heating with a pellet stove installed into the fireplace in the L.Rm.. Any idea if corn is cheaper than wood pellets with a delivery to the Sturbridge, MA area (W. of Worcester, MA)?
June 23, 2008 at 10:36 am
Hi,
Currently, I have an oil furnace (forced hot air).
I’m looking to buy the Harman PB105 boiler and connect it to a heat exchanger within my existing duct (either return side or in the plenem above my existing oil furnace). Has anyone done this. Also, I have an 80gal. electric hot water heater. I would like to use the Harman boiler for hot water in my house. However, how fast can it produce hot water when compared to and electric hot water tank? I plan on keeping the electric hot water tank as a backup.
June 29, 2008 at 12:56 pm
I have thoroughly enjoyed the heat my Harman p38 pellet stove has put out since I got it in Jan. of this year. Kept the thermostat at 50 so the stove took care of all the heat I needed. Can’t wait til I can get a silo instead of lugging bags! I’m finding good hardwood pellets keep the cleaning needed each week or two to a minimum. Looking forward to eventually doing an alternative water heater as I rarely run my oil furnace for that.
July 1, 2008 at 4:46 pm
I’ve been heating my house for 7 years with a wood pellet boiler providing hot water to some 15 radiators and for shower water etc.
I have some 10.000 litres of pellet storage integrated in the basement of the house, enough to satisfy my boiler for one year of automatic operation.
This is the future for New England and elsewhere in the U.S.
Since I am a manufacturer of this type of technology, I see a coming demand of this technology due to high oil prices and general recession. I’ts time to drop new kitchens and travelling and focus on living cost and money savings and this will drive customers over from pellet stoves/oil boilers to complete pellet boiler systems.
And by the way, there are a lot of trees in Canada and they are screaming to get rid of the huge amounts of pellets they are producing, the same goes for several other countries.

Sweet!
In my case, if all goes well, I’ll be loading firewood a couple of times a day into an EKO-40. This choice was driven by an urge to diversify sources. I already have a pellet stove for the living room. I wasn’t sure about committing to pellets — a manufactured product — on a grander scale. Yes there are lots of trees, but it’s my understanding that the first wave of relatively cheap pellet supply was based on availability of wood byproducts that could be repurposed, more than on harvesting of trees. When we get to the point where it’s all about harvesting, I figured I’d rather be one step closer to the source.
And while the option to go fully automatic is wildly appealing, I couldn’t see accomplishing that on my budget.

Agreed. Things are about to get a whole lot more primal for a whole lot of people. Which will be good in the long run, I think, for a lot of reasons. Once we get past “Who moved my cheese?” and start dealing with the reality of our new situation, I hope a lot of things will start to move in right directions.
In particular, I’m looking at the economic upside of:
- putting people to work manufacturing modern/clean/efficient biomass-burning technologies in the US
- putting people to work in a burgeoning industry of sustainable forestry
- putting people to work in a burgeoning industry of home retrofitting

I am trying to decide between an automatic pellet boiler to tie into our hotwater radiator, and which I hope will produce our hot water, or a geothermal.
The geothermal, assuming the well will work, will perhaps not tie into the iron baseboard radiators–I’m not sure. Not keen on the duct work, and I don’t like forced air. Appparently it does not provide enough hot water, so that would need to be supplemented.
I like the idea of not burning anything with the geothermal, but we’d have to burn something to get hot water, apparently.
I was told that in Maine the ground loop system doesn’t work so well due to the frost heaves. Water will need to be discharged.
The hot air is appealing for the air conditioning, but I’m not sure that we need it.
I will talk to some geothermal installers shortly. The first one who came seemed more interested in selling the pellet-fired furnace.
And with the pellet stove, we have to get the chimney lined, which is another drawback.
If anyone has more info on the pros/cons of the pellet furnace, would like to hear.

Hi,
I was looking to buy the Harman PB105 but was told that Harman
is unable to keep up with demand and will not be shipping any
units until April of `09. For now I went with a pellet insert
from St. Croix (The York), should be installed sometime in August. A little pricey but will help until next year when I
try and buy the boiler.

just a response to a comment i read here, contrary to what you may have been told, corn does not produce as many btus per pound as pellets does, corn is usually less than 7200 btus per pound as where pellets will burn anywhere from 7500 to 9000 btus per pound and at a cheaper price than corn (right now anyways), i am in the heating business so this information is acurate and not just my opinion; so in a nutshell, if you farm and have corn, sell it and buy pellets, you’ll save money on your heating bills

I just checked the first comment in this thread, from my friend Rob Mitchell, posted New Year’s Eve 2007:
“As a fellow New Englander we’ve considered alternatives to fuel oil, but we’ve stuck with oil for now.”
I saw Rob recently. Their plan, six months later, for this upcoming winter, is:
- Insulate the basement.
- Shut down the second floor for the winter.
- Buy a woodstove and lay in a supply of firewood.
- Bang out a wall on the first floor to help circulate the stove’s heat.
It’s crunch time here.

Hi Susan,
The pro’s for a geothermal system w/deep well are following as far as I see it:
Well proven technology
Automatic operation
The disadvantage is high investment cost and you are tied up to the price of electricity. This price will , in my opinion, follow the price for oil, gas and coal.
If we are talking about a centralized pellet boiler in the basement or outside to heat many radiators and providing hot water for other utilities, then the pro’s are:
- Pellet boilers are similar technology to oil or gas furnaces, you can use the existing radiators etc.
- Pellets are fairly cheap and they will probably be cheaper in the long run compared to other alternatives.
- It’s more environmentally friendly than geothermal systems if these operate on electricity made from coal or oil.
The disadvantage is that you need to follow up the boiler and clean out the burner head etc. on a regular basis. It doesn’t take any longer than to wash some clothes.
You can check out pellets.info, a Swedish pellets forum. On pellets.info/viewforum.php?f=39
you can find pictures of different solutions.

Rolf, I found and restored your comments, thanks!
“The disadvantage [for geothermal] is high investment cost”
Being heat-pump-based, isn’t it also happier in a milder climate than a more extreme one?
“you are tied up to the price of electricity”
Because you have to pump a lot of water to effect the heat exchange, right?
“[pellets are] more environmentally friendly than geothermal systems if these operate on electricity made from coal or oil.”
Yes, because they burn as cleanly, but are releasing carbon that would’ve been released anyway if the trees weren’t harvested and died a natural death. Versus coal or oil whose carbon would have remained sequestered.
“Pellets are fairly cheap and they will probably be cheaper in the long run compared to other alternatives.”
What about versus firewood though? I wound up buying a wood gasifier partly because I figured that it’s better to be as far upstream as possible. In a pinch I can buy a woodlot and produce my own, like a number of friends who own woodlots do. I can’t produce pellets.

Greg:
The name of my pellet boiler is Ariterm. It’s a swedish pellet boiler with integrated burner. http://www.ariterm.se.
It’s close to 7 years old. Today I would probably chose a burner from http://www.Ulma.se or a similar technology. The boiler from Ariterm is excellent but the burner is kind of old fashioned and needs to be cleaned fairly often.
Thanks, Jon, for restoring my comments.
A fluid to fluid heat pump needs electricity to lift the temperature up from what you are picking up in the well. The further you have to lift the temperature, the more electricity you use in a heat pump. Radiators need higher temperature to heat up the house compared to water borne systems in floors and this will increase the necessary electricity usage. An existing heating system based on boiler/ hot air furnace with radiators or hot air ducting is the ultimate basis for converting to pellets.
When it comes to firewood heating in a boiler with accumulator tank, you need a lot of wood to heat up a large house during the winter. In bulk storage, pellets use around 1/3 of the volume compared to wood and is automatically fed to the boiler.
It’s more comfortable and handy with pellets but more expensive if you can get firewood cheaply. I use firewood in a stove during week-ends in addition to my pellet boiler.
I certainly believe that the US market for pellet boilers will explode the next 2 years.
There are two major factors coinciding:
Firstly the oil price have exploded and will probably increase further (ref. Goldman Sachs).
Secondly I believe we are entering stagflation in the whole world starting out in the financial world where there have been no limits or regulations. This means that most people will start to save costs instead of spending money and they will aim to reduce the price of energy, for example by buying smaller cars. (GM is in deep shit).
When the above occurs, this will be the time that I start making money from my new conveying technology for pellets. Yesterday I got an order from a school in Sweden for this technology, see http://www.matene.com.
If anyone reading this is interested in making business out of pellet technology, I’ll be attending the http://www.bioenergydays.com in Minnesota late September together with other Scandinavian companies.

I’m loathing the fact that my wife and I purchased a pellet stove. We live in NJ and pellets are once again almost impossible to find this year! I hate this thing and wish we would have put in a messy old wood stove instead, I have loads of dead trees in the area.
I HATE THIS THING!

First timer in So.Eastern MA.
I purchased a Harmen insert two years ago.
My wife and i love it.We go thru 2 1/2 tons
a year for 1600sq ft. home.Also this year installed Andersen thermal windows and a
System 2000 Energy Kinetics heating system.
Hopefully will see major savings.Still putting off filling my oil tank hoping oil will go down further.Will let you know what
savings i see.

ALTHOUGH I OWN A PELLET INSERT WHICH IS HIGHLY EFFICIENT AND SAVES ME DEARLY IN PROPANE COSTS, DEFINATELY AN ECONOMIC OFFSET, I AM SERIOUSLY CONSIDERING A GEOTHERMAL UNIT. ALTHOUGH, THE INITAL COST IS EXTREMELY EXPENSIVE AT 16K, THE FUTURE REWARDS FAR OUTWEIGH THE COST OF OTHER METHODS. MOST IMPORTANTLY YOU GET THE BENEFITS OF A/C IN THE SUMMER AND HEAT IN THE WINTER. THIS IS A RENEWABLE RESOURCE WITHOUT WASTE AND IN 8YRS IT PAYS FOR ITSELF ASSUMING YOU WOULD USE 2K A YEAR TO HEAT AND COOL YOUR HOME USING PROPANE

I have a Harman PB105 wood pellet boiler that I want to use will my oil fired boiler. Would like to talk with someone who has tried this type of setup, looking for some information on the operation of this setup.
Thanks Bob
October 14, 2008 at 10:36 pm
Chris - have you checked out http://www.pelletsales.com yet? They have premium wood pellets in stock and deliver them to your home. That’s where we got our pellets this year. Good luck!
November 2, 2008 at 1:20 pm
Bob lamere; I am using the pb 105 pellet boiler with my oil boiler and it seems to be working well. I have it plumbed in series so I can shut it down in the summer months and use oil. My next move is to install one more shut off and bypass to completly take the oil boiler out of the loop to save on wasted B.T.U.’s. The pellet boiler needs to heat 10 gallons of water and the 3 cast iron plates every time a heat or water zone calls for heat. This is about 20 to 25 percent of the water volume plus the cast iron. This should make it that much more efficent. Hope this helps. Charlie

Hey all:
To those asking about steam conversion with some piping modifications the steam radiators could be used with the harman pb-105 boiler. If anyone’s looking to buy a pb-105 I have a one year old one for sale installation is possible as I’m a plumbing and heating contractor. I’m getting divorced wife has house and can’t maintain unit so I’ll be putting oil boiler online

I have a new install PB 105.. It is in series with old oil unit. I heat two zones plus hot water… I am using about 120 lbs of premimum pellets a day… Average outside temp is about 20 degrees… The guys that installed it set high temp to 180 degrees… No way in the world it will ever get there… Room temp with the computer runs about 154 to 165…I keep house set about 67…I know I am losing heat in oil boiler but hesitate to change setup as we travel for long week-ends and if pellets run out pipes might freeze… Anyone have any ideas how to bypass oil and have it usable either automatically or manually before I get ready to leave…
December 23, 2008 at 10:07 pm
I recently installed a PB105 in series w/oil boiler. Setup works very nicely. Turn oil down about 20-30 degrees below pellet setpoints and ensure pellet low setpoint is above oil high setpoint. I have tankless DHW in the oil boiler. This also works just fine. I use about 80 lbs/day w/2500 sqft home, 1992 construction, with additional attic insulation. I’m in Massachusetts and it’s been lower than 20 degrees lately.
