I'm in the process of installing a stoker with a hot water loop in it that I will plumb into my 30 gal. Aero Loboy hot water tank (oil fired) to heat domestic hot water. When I'm done the oil burner will still be able to fire under high demand, I'm hoping most of the hot water needed will be supplied by the coal burner.
That's exactly what I need to do.
I have been tossing around a few ideas on how to use the coil.
One was to circulate the water thru the coil in the stove, then into the oil furnace. I have a 41 gallon indirect-fired boiler hooked up to the oil furnace as a 4th heating zone with it's own circulator (absolutely CANNOT run that thing out of hot water! Works great!!). The little computer on the boiler sends a signal to the oil furnace when it needs heat & it kicks on the circulator & the oil burner, if needed. If I could get the water in the oil furnace hot enough, the burner would never kick on to heat the hot water in the indirect tank.
The furnace also has a tankless coil that we used to use for hot water (sucks). It's not connected to anything now. Was thinking I could circulate the stove coil water thru that to heat the furnace, but judging from the sucky hot water we used to get out of it, the heat transfer will be useless.
The other idea I got from Greg -- run the icy cold water from the well, thru the water coil in stove, then into the indirect tank so the water is only being heated a few degrees versus 80*. But I would have to get another tank (i'm running out of space here!) to circulate the water when we're not using the domestic hot water to prevent a
Another idea I had was to get an 80 gallon tank connected to the stove & hook everything in parallel to it from the oil furnace. That way i could use the hydronic heat too. I'd probably have to slow the circulating water waaay down to get any kind of heat out of it, though.
I'll figure something out eventually .........I figure this is easier than insulating the house!
