Electric water heater for floor heat.
Posted by Dennis on February 10, 2004 at 08:51:28:
I am having trouble with my floor heat keeping the temp (air) constant. I seem to have about an 7-8 degree swing and when the outside temp is really cold, it really don't keep up at all. My area is only 30x40 ft. The water heater is a 40 gal electric with a pump and an expansion tank installed in the line. I have a heat only Honeywell thermostat on the wall (inside wall). The water heater hardly ever shuts off. Should I have used a gas heater instead? I understand gas will recover quicker.
