The Hawken Energy HE is an outdoor wood furnace with a water capacity ranging from 150 to 368 gallons and a heating capacity ranging from 144,000 to 358,000 maximum BTU. The unit's water jacket completely encircles the structural steel firebox. It has a large wood loading door and an easy access back door, and the furnace is mounted on steel legs which eliminates the need for a concrete pad and helps keep rodents out. An automatic forced draft fan provides faster heat, and a stainless steel chimney cap keeps water out of the furnace while lowering heat loss. The powder coat metal exterior features enhanced green paint with black trim. The 2015 starting price of the HE furnace is $6,495 plus shipping and installation. Financing is available.
I have had my stove for less than 5 years. I developed a leak in the system. I was told to empty the stove and take pictures, which I did. Right away Rich in technical support started right off telling me my warranty was void do to water samples. He didn't show all of them, then he told me I didn't maintain my ash good enough, all before he knew where it was leaking from. He then had me refill the stove and find the leak. It's in the top of the stove, in the water jacket. Ash didn't cause that. They then sent out the repair guy and he said it wasn't caused by our error, it failed prematurely. Now they want me to pay for the repairs and say the stove only has a couple years life left in it, what happened to the 20-year guarantee? They look for every reason they can to not warranty their product. I have had cheap stoves last longer then 5 years. I will probably seek a lawyer because at this point I have a ten thousand dollar boat anchor. I will not recommend to anyone and I only live 15 minutes from the company.
I live in central Wisconsin and paid over $3500 in propane last year. I studied outdoor wood furnaces before I decided to purchase a Hawken. I am glad I did. I love my unit. I work 12-hour shifts and I have an hour drive time to and from work. The burn time of my furnace is around 16 to 17 hours when it's near zero and around 24 hours when it's near 30. I burn only oak and do not split it if I can lift it. I think that is key. People have a tendency to split their wood too small and it just burns to fast. It's been in the 50's lately and the burn time has been like 50 hours or better. I am heating a 2000 square foot log home and it has no problem keeping the house 73 degrees all winter. It is the middle of March and I have not even burned 4 cord yet. I read people burn a lot of wood and just want to tell them, quit splitting your wood. I have a 30 by 50 pole building. Next year I am also going to heat my 30 by 50 pole building with my unit and I believe the unit will heat both with no problem. Love my Hawken.
I purchased an he-2100 in the spring of 2009. It keeps a house of 1900 square feet at 68 degrees. As of now, I'm running a 1500 watt electric heater to supplement, due to minus 6 degrees temperatures outside. I run the water pump 365 days. Replaced it last summer due to the hours on it. I will keep it as a spare. Nice unit.
After having an indoor forced air wood burning furnace in use for the last four years, and after having to bring the wood into the house and have all the fine particulate ash and smell in the house, I plunged into the outdoor wood furnace/boiler arena. I looked at several major brands, and after months of poking and talking to others and reviewing websites and forums I decided on a Hawken Energy he-2100. This unit is easy to operate and we have all the heat we need and then some for our 2800 square foot home. Plus, we use a plate heat exchanger to heat our domestic hot water, which has yet to run out even with two teenagers, laundry and dishes all happening consecutively. I bought a unit bigger than my house needs so I can eventually heat a pole barn when that gets built. I also like that, for me, the unit is made in my home state so should warranty work ever be needed during the 20-year warranty period, the manufacturer is close by.
Purchased my he-2100 last fall. No problems, except for some of the caulking peeling up. Heated my large home nicely and didn't use a ton of wood. It was the coldest winter in eighty years, and we only burned 12 ricks of wood and kept my house 78 degrees all winter and had more hot water than could ever be used. I will begin burning in the next few days. The only people around here that don't like a good outdoor wood burner are the electric companies!
