I'm going to do some reading on here but is it possible to heat up a house to 80 degrees with a boiler? If I could find a decent boiler for under 6 grand with all the parts I would totally do a boiler but an air stove would be much cheaper from what I'm reading. I'm just nervous about a boiler because of water freezing up or rusting out my owb or keeping my home warm enough. Are people really getting 10 to 14 hours before filling up their owb and can I get some pros and cons for a nice stove, also is it worth buying the biggest one I can afford? The less I have to fill it with wood the better obviously.
1: I was picking corn late one night, wife wasn't feeling well and had the chills. Instead of turning the thermostat up, she turned the fan to manual on the thermostat. It was 86 when I came in late that night. Went back outside and stripped the Carharts and most of the rest of my cloths off, spent a few minutes trying to figure out WTF was going on after I walked around and opened most of the downstairs windows. Next morning I made it quite clear she was never to touch the fan switch again and it was ALWAYS to be left on Auto. OWB did that. 80 shouldn't be problem unless you're still using animal skins for windows and a chunk of canvas tarp for a door.
2: You get what you pay for, old farm house originally had a coal furnace, that was converted to oil, then had a wood furnace in the basement. Father and both his parents said this old house was never as warm as it was before I went with a outside boiler. House stays cleaner and the humidity stays up a lot better no matter how cold it gets.
3: My home built is going on 14 years old, no leaks, water looks clear. It would have to be out for days before freezing was a real possibity. Bypasses could be installed so no water flowed thru a sidearm or plate HX and your duct HX.
4: If filled clear full of oak and red elm I've gone two full days, most efficient though to only fill enough to get a 12 hour burn at a time.
5: Size it according to your heat load, if it's too big you could have the very real possibility of it going out on warmer days as it won't cycle enough. Bigger also costs mucho more $$$.
