Basic information about electric radiant floor heating

A comfortable, easy to install and energy efficient way to heat your house is to install an electric radiant sub floor heating system. In this article, you will find details about the kind of wires needed, insulation that must be installed with the system, functions and features of the thermostat, the method of installation and other basic information.

First, you need to know that your heating wires must be resistant to electricity and insulated properly.

They also need to be protected mechanically to any damage and resistant to heat. Thinking about the use of 120 or 240 volts, you will need to use silicon rubber insulation and a metal braid which will protect against ground faults. In conclusion, you will need an insulation that will be resistant to 300 degrees Fahrenheit.

The electric cable which controls the temperature must be switched on and off by the temperature controller. This device will also detect ground leakage, but its most important role is to detect the temperature of the ambient air and also floor temperature. It is recommended to install a device which uses a thermostat and an input for the floor temperature sensor. This device can be programmed to automatically turn on and off to a desired temperature, over the night or when you are gone from home.

Now, you need to know that the process of installation in very important, so you should be very careful if you want good performance, durability and safety. First, you have to clean the sub floor very well. You will need to form continuous loops and try to avoid the crossovers. Make sure that you don’t cut or damage the cable loops and place them at least 1 inch apart.

Now you can check if your system is working properly and make sure that you done that before and after you applied the thin-set concrete. You must check the continuity of the system and the integrity of the insulation which must have a value of 10 megaohms. Now, you can apply the concrete over the wire. The protective layer should be about ½ inch thick. After that, you will install the resistance wire and the in-floor sensor to the controller device. Now, you can make a full system test and check for integrity, resistance and heat production.
