Flip.....how do you have the biomass stove situated in your house? Placed for optimum radiant heat, or have you tied it into your furnace system somehow?
It's a freestanding unit. Sits in the Northwest corner of the living room on a brick hearth on the first floor. It's rated conservatively at 50K BTU's per hour, burns wood pellets, cherry pits, pelletized switchgrass, shelled corn, or soybeans, whatever is cheaper. I tend to burn shelled corn and pellets mixed and I run the furnace in the basement on blower only to distribute the heat throughout the house. because the unit runs 24/7 during cold months, 50K BTU handles the whole house because the heat is constant, mostly convection and some radiant from the front of the unit. It has blowers in the cabinet. It's all computer controlled and thinks for itself plus it's very safe with shutdown monitors if a malfunction occurs.
I do have it on a remote digital thermostat but I tend to keep the thermostat at 70 and the house stays about 68. The only time I used the furnace is if we have a stiff wind from the west and then I'll allow the furnace to help out a bit. It's on a digital thermostat as well.
I consumed about 200 bushel of corn last winter and 4 ton of pellets running 24/7 from mid September until mid may. That's about 1300 bucks or about a third of what I'd pay for propane for a year.
This year I got propane substantially less than last year, I own 2-500 gallon tanks, so I filled them. Corn is around 100 bucks a ton (56 pounds to the bushel @15% moisture and pellets are around 210 a ton so I won't be at a third, maybe 1/2 this year.
I've been heating with renewable fuels/biomass for 13 years now and I like the independence and the cost difference. Nice warming heat that you have complete control of, both in cost and amount.
Units are made that can tie into your central heating system, be it forced air or hot water/low pressure steam.
I don't sell them but I have lots of contacts and websites. If you are interested, PM me and I'll provide them.
