Was wondering if anyone on here ever heated with a central boiler, outside wood furnace, HAHSA or anything similar.
I'm primarily interested for our house. But my wife has asthma and allergies, and the PPH. So wood smoke and dust in the house is a NO NO.
I hate to not use all the free wood that is laying around on the place though.
Any suggestions?
Thanks,
Patrick

I have not but I have many friends who use a wood furnace with hot water radiant heat and love it. Most are farmers and heat far more than their houses with this system.
Currently I heat with natural gas but heated with wood for 15 years using an indoor stove. Can't say I miss the bad air and dirt from bringing in wood all the time. I would still be heating with wood if I hadn't bought a farm that had no place to put in a stove in the house. I still want to put in a wood furnace to heat the house, barn and store (and maybe a greenhouse when we get one built) and plan on doing so in the next several years.

I have comtemplated putting an external wood boiler in our next home, but wondered how much I would enjoy filling the firebox with 4' logs each day when I'm in my 60's ...

we also have two indoor woodstoves right now. wood is getting hard to find around here now with selective cutting and all. the stupid government burns the slash piles that people used to be able to pick through for wood now, too. what a waste.
hubby is working on plans to build a 'bale' burner outside like the HAHSA mentioned above, then having pipes with heated water go throughout the cabin and greenhouse floors. he figures we can bale up weeds if need be to burn.

What I'm planning on doing is hybridizing all the best parts of all the wood-heating system.
I'm going to build a wood gassifier and try to capture the heat with coils of copper in sand surrounding the fire chamber, and also from coils inside the chimney. Transfer it to a large water tank where it will circulate through some coils and drop off the heat in that water. Then have a second set of coils to pick the heat from inside the water tank and circulate it through the floor system and possibly my hot water heater.
It isn't a perfect system I'm sure, but I think it is a good compromise.
My brother in laws dad works for a Propane company. He is checking on getting me an old propane tank to use as my fire chamber.
A gassifier uses a fan to inject air into the firebox which makes the fire burn really hot, then in a secondary chamber the combustion gasses are burnt also, so it burns very clean, very hot (sometimes above 2500' F, so the chamber has to be lined with firebrick). But not for very long. That is why I'm going to use the water tank (1500gal) to hold the heat until it is needed in the house.
