I am experiencing my first winter in my new Minneapolis, MN home. The house is heated with a gas boiler and baseboard heaters which work well. However the previous owners converted the attic space into a master suite and installed an electric baseboard heater with its own thermostat. They claim to have insulated as best they could when they did the conversion, but it is absolutely freezing up there and we end up keeping the electric baseboard at 70 degrees all night.
I have heard that electric baseboards are electricity hogs - is that true? Am I burning through money by leaving it on almost 24/7? Also, I think I could run water pipes up from the basement which would give me a standard hot water baseboard in the master suite which I could then zone. Would it be worth it?
