Would you like to heat your underfloor heating electrically instead of using gas? When choosing electric underfloor heating, you have a choice of various types, colors, sizes, and wattages of heating cables. We're happy to explain the differences and which one you should choose!
Step 1: Cement screed or dry construction
First of all, it's important to know what type of floor you're going to install your underfloor heating under. Is it a cement-based floor (also known as wet construction) or dry construction? In short: cement-based electric underfloor heating is specifically designed for installation in cement screed floors . The electric underfloor heating is then integrated into the cement floor. This is often the case in new-build homes. Do you want to install underfloor heating in an existing home? Then you choose Dry construction . In this method, the pipes are attached to the cement floor with insulation boards or studded plates. This is often done in renovations and existing houses.

Cement-based electric underfloor heating
Within the cement-based underfloor heating pipes, we offer two types of heating cables. The Magnum electric underfloor heating is specifically designed for installation in cement screed floors. So, if you want to install electric underfloor heating in a cement-based floor, there are two types of underfloor heating cables suitable for this: the Magnum electric heating cable. 10 Watt per meter or 17 Watt per meter.
Magnum electric heating cable 10 Watt per meter
The Magnum electric heating cable, rated at 10 watts per meter, is therefore suitable for cement screed floors and is often used in new construction. Installation of these heating cables is simple because they are malleable. These cables are not suitable for installation in lightweight concrete. Below is an overview of all types of electric underfloor heating, rated at 10 watts per meter.
