Under rug heating

[boilerfrustration]

I have a log fire in the living room but no central heating. I can't justify ripping up the wood floors to install underfloor heating but I am aware of under rug heating. Is this type of heating effective and most of all safe? Can it be connected to a thermostat?

There is a chemical type underfloor heating where the resistance of the chemical increases as the temperature goes up so it is to some extent self regulating.

However to control electric under floor heating a double thermostat is used, one probe goes in the floor to limit floor temperature the other in the air to limit air temperature.

Hysteresis is a problem, in real terms under floor heating needs to run 24/7.

Likely the cheapest to run electric heating is the fan heater, not counting refrigeration methods, but it is noisy, so some compromise is required, the lighter the heater is the less delay there is from turn on to getting heat, inferred is really good for places where there are regular air changes but near impossible to control the heat, they or either on or off, no real control.

The underfloor heating is likely the most expensive to run.

Back boiler on wood burner, with a large insulated tank, and a radiator with a thermostat controlled pump, so a good burn does not end heating when fire goes out, but continues to heat hours after the fire has gone out.
