How to select and install the correct heating cable for underfloor heating
How to select and install the correct heating cable for underfloor heating.
In this case we are considering the installation of heating cable.
It is better and cheaper to use heating cable. Heating mat can be used only if it is not possible to raise the floor level or make a recess in the floor screed.
- The standard heating cable output for underfloor heating is 18 W/m. A more powerful cable can be used for heating poorly insulated rooms, ground floor flats, loggias, etc.
- Each room should have its own temperature controller.
- Laying the cable correctly is very important.
- The heating cable should only be installed where there is no furniture, carpets, etc.
- The indentation from the walls should be at least ten centimetres.
- As the lengths of the heating sections are standardised, it is not possible to find the perfect fit. Select a heating section with a length shorter than required.
- For proper use of the heating cable, the floor level must be raised. This can only be done in new homes by installing the heating cable before the screed is poured. If the screed already exists, it is necessary to make indentations in it where the heating cable is to be installed.
- Be sure to use thermal insulation when laying the cable. Twenty millimetres of styrodur will be sufficient. As there is no such thing as too much insulation, if you can, lay more.
- The cable must never be fixed to the thermal insulation. If the cable comes into contact with the thermal insulation after casting, it will overheat and fail. The cable must be in a cable tie on all sides.
- It is better to pour the underfloor heating in several stages.
- Cover the thermal insulation with screed first. Then wait for the screed to dry. Then fix the heating cable to the mounting tape and re-pour. It’s better, but it takes longer.
- If there is no time, the second method will speed up the process somewhat. Lay the styrofoam and fix the cable to the mesh. During the pouring process, maximise the penetration of the mortar under the mesh. This is to prevent the cable from coming into contact with the thermal insulation.
Heating cable with a thermal insulation layer will allow you to maximise the efficiency of your underfloor heating system.
The heating cable laid in the screed will allow heat to accumulate in it, and the thermal insulation will avoid senseless heat loss.
The main purpose of underfloor heating is comfort, but saving money while getting comfort is just as important.
The extra effort and time spent installing underfloor heating is quickly compensated for in the form of comfort and energy savings.
