When I connected my Central Boiler to a heat exchanger in my forced air furnace plenum in 2012, I added a separate thermostat so I could run the wood source heat exchanger without using my previous (and still in place) primary heat source, an air source heat pump with oil backup. For the past couple of winters I've stopped using that separate t-stat, instead using my heat pump, which of course uses the heat from the C.B. whenever the furnace fan comes on. I did this thinking I would realize some savings on my electric bill, and some savings on my wood supply, but not perhaps as much as if I'd run just one or the other. I can't say that I have saved on either - didn't try to compare before/after (plus I think it'd be difficult to get a fair comparison).
So I'm asking, do you guys think this (a little savings on both wood and electricity) is a correct assumption? Or was I better off just using the wood-fired heat? I'm getting older and harvesting my own firewood is getting old, too
