I have a 60 ranch walk out basement home with electric baseboard radiant heat and an electric hot water heater. My master bathroom is on a north facing wall in zone 4 (Wisconsin). We are going to do a total gut and redo of the bathroom. I would like to convert the electric radiant baseboard to floor and wall hot water heat with an electric fired boiler located in the basement. The boiler could also be combined with domestic hot water. The size of the bathroom will be about 12' x 12' with 8' ceiling. At a later date we would also like to add the hydronic heat to the basement floor that covers about 28' x 28' with 8' ceiling. Is there a small electric boiler/domestic hot water heater that would be sized correctly for a 2 zone system (bathroom and basement) for the 1600 sq foot application? Is there a boiler that could be hung on the wall? We live next to a creek in a flood prone area so I don't want to use the electric in floor radiant heat because the basement floor sometimes gets wet. Also if we could elevate the boiler and hang it on the wall, when the creek rises we don't have to worry about anything electric in the basement getting wet. Any suggestions? And don't tell me to move because of the flooding. The area is so beautiful I can live with the occasional flood.
