Does the heating cause structural damage, such as cracking of the slab or tiles?
No, because the floor heating does not cause the concrete to become too hot. In fact it will not become as hot as your footpath will become on a sunny day. Cracking may occur if the heating is used to cure the concrete quickly. We recommend that the heating should not be activated for at least two months after pouring the slab or one month after tiles are installed into a sand/cement topping. If in doubt, please consult the flooring manufacturer or DEVI Comfort Heat.
