I'm in the market for a combination furnace (hard coal - oil). I'm leaning on the EFM 'cause I got some friends that very highly recommend it. I currently have a very tired [hand fired] National soft coal furnace x-connected with an (almost as tired) oil furnace in a hot water system in South Western God's Country (PA). They're wired on two different thermostats.
First off, I've got a little money put back and wondering if I can do this. I've got a buddy who can help me put it in (professionally) so, conservatively, what would I have to spend for one of these?
Also, can an EFM combination furnace automatically switch to oil if the fire goes out? (The wife ain't real good at keepin' fires when I'm away).
Would appreciate any help,
Dave
