Wood waste for heat11/5/13
I have a 10K square foot shop and I want to look into some kind of waste burning to heat the shop. Anyone out there using a certain type of setup or manufacturer. Any info. would be appreciated.
I have had experience with duel fuel furnaces. Forced hot air like a normal oil or gas burner, but with a wood firebox and approved chimney. Ductwork and a fan distributed the heated air through the shop.
You feed it wood while you can, and then it converts over to the secondary fuel if no wood is in the firebox.
These were thermostatically controlled, with night time setbacks. Very convenient.
Be sure to talk to your insurance people. The shops I ran that had these were always under pressure to add sprinklers. Pressure being higher premiums.
I've been heating my 10,000 sq.ft. shop with an outdoor wood burner for six years. It sure feels good to not have to pay for LP anymore.
Before putting in the paint booths I was able to heat the 7 man shop entirely with wood scraps and sawdust all winter long. The sawdust was processed with a Weima briquette maker. I now also have to make a fair amount of firewood to keep up with two 24" exhaust fans in the paint booths. I have them on motor drives so we can slow them down when possible.
It is fairly labor intensive but I love making and burning firewood. With the outdoor stoves you don't have to work up the firewood into small pieces so that helps.
It's not for everyone but as I said, I love it.
My insurance company doesn't have a problem with it.
If I were to start from square one, I would do a separate wood burner like Gary mentions. It just feels safer than having a fire in your woodshop - that's a hard one to get over.
I once heated a home shop with wood - a stove in the corner, with proper flue and non-combustible surround - until the insurance people changed their mind and told me they would not cover it.
What I had in mind was a separate concrete block building attached to the shop. It would be totally separated from the shop with the exception of the duct work for the heat. Gary, where did you get the wood burner from?
I just replaced my big Central Boiler with a bigger Heatmor stove. I also have a Woodmaster at my house. All three have been good stoves.
My Bio Heat outdoor wood boiler seems to be pretty efficient . Thermostat on forced draft , water to move the heat around . Cut heating costs by about 85% . Fluff trees make fluff smoke . Better trees make better fluffy stuff .
Do you use melamine or MDF as well?
We burn any and all shop waste. MDF, melamine, plywood, solid wood. It all burns with less smoke with a forced draft stove.
I have an outdoor wood boiler as well... can't see any other way to heat a shop. ALL scraps go in (with the exception of the large hardwood cutoffs that my employee heats his house with).
I am unfamiliar with these, do they heat water for radiant baseboard heaters or how do they work? thanks
They can be set up to heat however you want with hot water. You can use existing infrastructure or new.
