Has the jury decided what kind of supplemental heating is most efficient for Eichler homes? Space heater, radiant heater, etc. ? We just have too much carpet, extra flooring layers, etc. My mother-in-law will soon be here for 8 weeks this winter, and I'd like raise the temperature beyond low 60s, as efficiently as possible, for at least the living room and kichten areas. The bedrooms are not so important.
Any ideas appreciated.
