I'm trying to figure out how to solve an issue with an 1800s barn here in vermont that is my home. The water comes into the house into the unheated, un-insulated basement (where the cows used to live). Floors are dirt, barn wood walls. There is a room for the water pipes, insulated, cement floor, and with an electric water heater in the room, blanketed. Upstairs is the living part of the barn, heated with wood stove heat in the winter. I've been paying a rental fee for the hotwater heater for years, and more than half of my kwh use is from the water heater. The water heater has been helpful in that it helps add heat to the water room in the winter and aids in preventing the pipes from freezing. I also have a fan that vents heat from the upstairs bathroom down to the water room. And I have anelectric space heater that is on a thermostat in the water room. It gets to 20 below zero in the winter here.
I don't want to continue to pay a rental cost for an old water heater. I can purchase the heater for $100, but that seems a waste, given how old the heater is (over 15 years). I use wood heat over 6 months of the year.
*Should I get rid of the downstairs water heater and figure on heating the room via the space heater only. (any other good ideas?) *Does an on demand water heater make sense? Or a tank water heater that I can heat part of the year via my woodstove? I only need hot water for a shower and sink. I don't use hot water for the laundry.
