Seems I once ran into an off grid customer that had an outdoor wood boiler set up energy free.. the boiler itself is physically located below (Down hill) from the house and is plumbed with like 2" Pex so it uses gravity to circulate and a smoke stack tall enough (and insulated) to conjure a decent draft. they also have hot water lines running out to the diesel gen set for co generating heat. (Both for gen set block heating and for dumping exhaust heat). For thermal storage, they have an old dairy bulk tank in a walled off room with truck radiators in the tank connected to manifolds out side the room. the whole room was filled with recycled styrofoam peanuts. the tank loop is connected to the boiler, a kitchen wood stove and a radiant slab, the radiator manifolds are connected closed loop to SHW on the roof and domestic hot water. Yes, he's an old Vermont Yankee farmer.

I have a Central Boiler brand of outdoor wood furnace. It has an electric damper that has to be powered whenever the fire is burning, which draws about 50 watts and a small circulator pump that draws a bit less than 100 watts.
I stopped using it years ago because it consumed so much wood, but it worked great. It was a great way to get rid of pallets.
Unfortunately it was most needed whenever there was not much sun, so it definitely increased generator run time.

Hi Wrenches,
Have a client who wants to install an outdoor wood furnace for hydronic heating in his shop and home. Wondering if any have had experience with these. It seems like an intensive off-grid load because of fans and/or pumps. Any experience or model recommendations is appreciated, thanks!
