To prepare a concrete floor for electric underfloor heating:
- Clean the surface thoroughly to remove any dust, debris, or contaminants.
- Ensure the surface is level. If not, consider levelling it using a suitable compound.
- Plan your layout. Determine where the heating mats will be placed, considering furniture and other fixtures in the room.
- Ensure you have a dedicated electrical circuit to support the underfloor heating system.
How to Install Floor Heating in Concrete
Installing radiant floor heating in concrete slab involves the following steps:
- Start by laying out the radiant heat mats, making sure they cover the entire desired area without overlapping.
- Connect the heating mats to the thermostat and power supply, ensuring all electrical connections are secure.
- If using insulation boards in the subfloor, place them beneath the mats to maximize heating efficiency.
- Once the heating mats are in place, pour the concrete over them. Ensure the concrete completely covers the mats and is appropriately levelled.
- Allow the concrete to cure based on the manufacturer’s guidelines before using the radiant heating system.
