Agreed, go start splitting wood. Wood needs to be seasoned 1 year, well preferred to be one year. While your at it plan on 2 years worth of wood ahead. And try to keep 2 yrs ahead. Trust me, makes a big difference in overall perfrmance, cleaning,etc.
Now you need to figure out how much wood you'll need. I only know the rough estimate of wood vs oil. 1 cord of well seasoned wood=150 gals of oil, thats if you buy a gasser or Garn. I was burning 1000 gals of oil a year, now I'm using about 6.5 cords of well seasoned wood.
Anyone know the rough figure for propane vs wood? You should do a heat load calc.
When i looked at an OWB, it cost as much as my gassification boiler and storage tank. Add a few more thousand dollars for install and I had a unit that burned a lot less wood than an OWB. And when burning, there is no smoke. None.
Also, you're in NH. Tarm boilers are set up in Lyme,NH. They got a couple of units set up for Demo on site, I think. BUT there are many very good units out there other than Tarm's. But it's local, to see what these gasser's are all about.
Google GARN. These are impressive units also.
My set up is a Tarm Innova 30 with 820 gals of storage. Located next door in my unattached garage, oops i mean wood storage facility. Tank is in basement of house. When i take my wood off of the splitter, it is stacked on pallets. Store pallets outside(hopefully after 2yrs of seasoning) till needed. Use my tractor to put pallets in garage, when needed. Cuts down on the handling of wood, and the need for a large area of storage for wood. I just put 1 cord of wood in my garage in under 15 minutes. And yes, I'm spoiled. Even got a heater and a radio.
Now I start 1 fire a day(in the deep of winter). Takes about 10 minutes at most. If it's sub zero, I'll go back out and refill boiler. Just depends on the demand. I've got 3 teenagers. they all know how to start a fire and when to refill if needed. They are always coming and going, someones headed out the door. The new phrase in the house is "Check tank temps, if needed go start a fire. And don't stay out late! If you do, fill the damn boiler!" But majority of time, we do one fire a day. So it's 10 minutes tending time a day. You have radiant floors! Hooray. These perform very well with a system of some type, with storage. If you can't do storage now, no biggie. Can always add on later.
Spring and fall times, i get 2 maybe 3 days out of storage. Summer we go 4 to 5 days for DHW. Thats on one fire. i run my oil furnace once in a while. If my tank gets too low on heat, the oil system will kick in automatically.
Hopefully didn't confuse you too much. this is a great site to learn from. Good people.
