Ceramic oven plus heated floor (electric).
Most comfortable house ever and pretty cheap as long as you can get the wood.
I built a heated floor. The floor is a 125,000 lb slab of concrete with water circulating in it that is hooked up to an outdoor furnace.
I usually burn coal in it, but can burn wood if necessary.
The heat is wonderful.
I accidentally over fired the furnace one winter when it was cold. The floor got so hot that my dogs refused to lay on it. Had to open the windows and it took two days to cool down.
I bought 50 ton of raw anthracite coal straight from the deep mine near me. One of my clients owned and operates the mine.
Problem was, mine run coal had boulders of coal the size of a sofa. I just lifted them up to full height with my backhoe and left it shatter when it hit the concrete pad the furnace sets on.
Hillbilly living can be fun.
By ceramic oven, do you mean a masonry heater? I’ve wanted one for a while.
Did you build, hire builders, or buy a house with it already installed?
As usual, I’m coming in late the discussion. Grew up on a winter wheat farm in the Dakotas. Heated and cooked with wood and coal as emergency backup. Then years later in N Minnesota - oil fed furnace for hot air, then later circulating hot water heat.
Cost per therm/kW in versus delivered kW-hr.
Now, living in an escapism state where I can afford anything but on-site nuclear -
I have extremely-efficient wood stoves in my library and bedroom. Otherwise, rely on super-insulation and reverse-cycle AC.
My problem is dumping the excess kW.
Happy to list vendors but so much depends upon design of habitat. R40 walls, R60 ceilings, even the floors are R-20.
I hauled wood behind a horse team, then chopped and split as a kid. Leaves lasting memories.
Sorry that many of you are constrained by not being an ornery engineer with dollars to spend.
