Inquiry (采购产品): electric boilers Is there an electric boiler to incorperate into a radient floor heat system? If so does the efficency of an electric boiler decrease with altitude as does a gas boiler? I live at 8600' above sea level, my house is 2300 sq.ft. R-32 walls, R-36 ceiling 10 ft high ceiling. The price of propane is up to $1.58 gal. My boiler is 82% eff.but at this altitude is about 50% eff. would an electric boiler save me money?
