I am looking at buying a Empire Elite 100 and adding the 18kw electric backup with a baseboard setup. My questions are how economical would it be to use the electric backup if I was gone for some time as compared to having a backup gas boiler in the system? And what do you think about using the electric backup for my hot water needs in the offseason? Would it be better to just buy a hotwater heater? I am buying a house from a buddy that is a contractor that bought the house and got a contruction loan to remodel it and he is totally against me using the wood boiler. I talked him into it, but can't add storage till after the inspection and I am also wondering if it would be practical at all to use the electric backup to keep the storage heated? Thanks guys I am trying to get my feet wet in this world and hopefully I can start pushing these setups to others cause they are awesome and it would bring prices down cause these boilers are way to simple to cost what they do.
