My outdoor furnace heats a blanket of water around the fire chamber, pumps the water underground to a heat exchange in my backup furnace vent system and then blows it throughout the house. One of the outside lines goes to my water heater and heats the water, and another to a separate building we have and heats it. It’s pulling quite a load really. Like any woodburning system, it loses heat up the smokestack, but it’s a long burn chamber so a huge amount of the heat directly heats the water.

Thank you for your response, I've never heard of that kind of furnace, at least an outdoor one.

Since it, is in essence an water heater, would it be possible to tap into it for a a small amout of water for bathing purposes? .

Not a bathtub of course but enough for miminal needs in case of power failure..

Back in '73 and again in '77 our power was out for about a week b/c of ice storms and during the day we cooked our meals upon the stand alone wood store we had then and put big pots of water to heat overnight and use it to wash, just enough to keep the stink down a bit.

Our insert stove(with blowers) we have now does a good job of heating the house but it's top doesn't have the space to put a good sized pot upon. Just a few smaller pots to heat the frank and beans and an old coffee percolator...

Just wondering, always open to a better option.
