Radiant floor heating is literally heat that radiates up through the floor.
For those of you who have never experienced it, it means when you step on the bathroom floor, it’s warm to the touch.
That, an electric towel warmer, and a steam shower, is the ultimate in bathroom luxury.
Most bathroom floor radiant heat systems are electric, where something resembling a very durable electric blanket is installed above the sub-floor and below the flooring material.
The diagram below shows the heating element prior to the flooring being installed.
The radiant heat element is not the red stripe, but rather is the almost clear layer in which you can see wires that run up and down. That red stripe is most likely some insulating material to minimize heat loss.
Being electric, there is clearly a control of some sort. As we all wish to conserve electricity, I recommend installing a timer switch so the floor heats up maybe 15 or 20 minutes before your alarm clock goes off. That way the floor is nice and warm before you head in for your morning routine.
Aspects of the installation that make additional sense is to install insulation beneath the heating element and/or sub-floor when you can to ensure heat loss through the sub-floor is kept to a minimum.
Done correctly, your radiant heat floor system will keep your toes warm for years to come. Now don’t forget that electric towel warmer.
By the way, radiant floor heating is not new. In ancient Rome radiant flooring heating by hot water was common in the public bath houses.
