Loose cable systems vs electric mats
- Loose cable systems
Electric underfloor heating mats make installation quick and easy. The wires have the correct separation allowing even heating
at the correct output. The mats are self adhesive meaning in most cases the floor doesn’t need to be primed before installation.
The quality of the mats are import as some mats have very flimsy mesh or are packed badly and will refuse to lay
flat when installing.
Mat layout guide
Unless you are experienced underfloor heating installer or have a very simple room it is always best to ask for a mat layout plan from your supplier. Rayotec supply free CAD mat layout plans for any of our underfloor heating mat customers who require one. It stops mistakes like ordering the wrong size or starting in the wrong place. As the mats are self adhesive it is best to get it right the first time.
If possible ALWAYS insulate under your underfloor heating system. There are special high density boards available that are designed so that you can tile straight on top of. The boards are available from only 6mm in thickness making possible to install in areas with limited floor height.
The major advantages of using insulation are:
1. Lower running costs
2. Faster heat up time
3. Easier installation
Rayotec sell a premium insulation board at a range of thicknesses prefect for any installation under tiles.
With underfloor heating you tend to have one thermostat per room. There are two basic types; digital and dial. The Digital is programmable giving far higher level of control and allows you to control running costs.
The thermostat will need to be located somewhere were it can detect the average temperature of the room. Locations near windows, radiators, fireplaces etc should be avoided. The thermostats are not IP rated and therefore should not be installed in wet rooms (bathrooms etc). A floor probe should always be installed to limit the temperature of the floor.
