Only you can decide this. But the main considerations will be:
Local climate
How much you, and other home occupants feel the cold.
The type of floor coverings
Your budget
The priorities are usually the bathrooms first, followed by tiled living areas,then bedrooms.
In a screed on top of the base floor, warmth is felt within an hour. Of course it also then cools down, more quickly.
Since storage is required for satisfactory operation of the controlled tariff systems, the cable is embedded in the base slab or a sand/cement screed and warm up time is a few hours. Thermal insulation assures temperature stability in these installations .
Once the building construction is complete, problems of damage are very rare. The cable is tested at installation and at connection.
Fortunately, if damage does occur, we have specialised equipment and techniques to locate the spot. A small trench around the cable is then dug, and it is rejoined.
Every category of floor covering has been used successfully with floor heating. Nevertheless, any unusually large thickness of timber, cork, or other insulating coverings should be checked out. Heatec can assist with operating temperature information and the manufacturer should then have the final say on suitability. Under most coverings, the concrete does not get nearly as hot as your footpath outside in the sun, or, the floor near most room heaters. Since the warmth radiates from a large area, temperatures are moderate, with 27 Deg C at the surface being common.
Any suspended floor levels which are open below, will lose heat downwards. Insulating-type floor coverings such as carpet, cork and parquetry, drive the concrete temperature up an extra 12 Deg C, increasing the problem. If open to the weather below, the underside of these slabs must be insulated. Heatec can assist with advice on practical methods available.
If the underside of the slab faces an area that requires heating, it may not be necessary to insulate below.
Methods vary. In this instance, Heatec’s equipment was used to develop a warm spot at the point of damage, which was detected with a thermal image camera.
