Just moved into new house (actually 20 years old, just new to us). It has fuel-oil baseboard heat with six zones.
The system works well, but now that hot weather is here the furnace runs a lot to just heat the Hot Water Heater. That seems very inefficient to me. Running a 100,000 BTU/Hr. system just to heat water. Would not a well insulated electric HWH be more efficient and then the furnace could be totally off for 8 months a year?
