Can you put underfloor heating on concrete floor?
Underfloor heating can be fitted in both concrete and timber suspended floors, but for other floor constructions (for example we also offer a ‘floating floor’ solution) please contact us.
How do you prepare a concrete floor for underfloor heating?
How to prepare your floor for underfloor heating
- Clean the area of all debris and dirt.
- Fit the insulation boards neatly and stable ideally with all gaps and joints taped.
- If using liquid screed, a membrane of between 500 and 1000 gauge must be laid as crease/fold free as possible with all joints taped and no gaps.
How thick does concrete need to be for underfloor heating?
The minimum screed thickness you should use for warm water underfloor heating systems is: Minimum depth of 65mm for hand-mixed screed. Minimum depth of 50mm for liquid screed.
Can you install radiant heat on concrete?
There are several manufacturers of electric radiant floor heating systems that can be placed directly on top of an existing concrete slab. These radiant floor heating systems can also be installed on top of a slab before the flooring goes down. There are several manufacturers of this type of radiant floor heating.
How long does it take to heat up a concrete floor?
If you have a non-insulated thick concrete floor it could take between 2-8 hours before the heat is felt. In contrast to that, an insulated concrete floor takes between 2-5 hours, while a concrete floor with a 10mm tile-backer insulator takes only an hour to warm up.
Do you screed over underfloor heating?
Most screeds are applied as floating screeds as this is most practical for placing on top of underfloor heating and insulation solutions.
What’s the best concrete for underfloor heating?
THE RIGHT TYPE OF CONCRETE FOR UNDERFLOOR HEATING SYSTEMS. From a technical standpoint, a concrete with a hardness of approximately C35 or 35 newtons with a water to cement ratio of less than 0.40, would offer a great starting point for the ideal concrete mix to use over heating.
