There is a company in Canada that makes under slab electric heat panels. They are designed to work with off peak storage electricity and do not use any insulation under the floor. They claim to heat a large storage sump with the cheaper electricity and the heat is released from the floor when the electricity is off. Has anybody seen or used this form of heat?

My question is how much energy is lost to the ground below. At some point say ten foot of dirt must have some meaningfull R value.
