Well I found the specs for my system, and it is 12 watts per sq/ft no matter if your using 120 or 240 volts. So for a whole house, it could get kind of spendy if your house is not very well insulated. But my system is not designed for a whole house, that system would have different rating. Electric forced air heat might be cheap to install, but not electric wires or mats for heat. Hydronic is probably the way to go for a whole house. Michael

Usually it is in a small room, a bathroom which might be a hundred or so square feet 25% or more of which is covered with shower stalls, tubs, vanities and so on. The ambient temperature of the dwelling will probably be around 70 degrees F so you aren't topping it up much. Heating an entire home that way though would be a lot more expensive. funny really, my first home nearly 40 years ago was all electric with R12 in the walls and R20 in the ceilings and promoted as being the way of the future. Within a couple of years though that turned out to be a myth. Electric heat is cheap to install though.

OK Mike, Then it sounds like the electric mats aren't as bad as I thought. Are you just using them as a comfort heat source and not a primary heat source? Are they thermostatically controlled or do you turn them on and off when you want the heat? I've been looking at hydronic for a primary heat source on the first floor of my house. -- Blue skies.
