    Dear all

    Any advice on what to do please! Our builder confidently installed our underfloor heating and it's been concreted in. We have a thermal camera which shows that in between two floor zones, he has run adjacent UFH pipes very close together. So there is a strip of floor which is getting hotter than the rest- in excess of 33 degrees.

    We are about to lay LVT tiles on top which state max safe temp is 27 degrees.

    What shall we do? Make the builder dig floor up and start again or lay the tiles and risk them getting damaged by the heat?

    The job has dragged on for nearly 2 years and builder wants to leave. We're fed up living with concrete floor.

    How important is it that floor temp doesn't exceed 27 degrees?

    Any ideas welcome

    Thanks

    Should be ok as I’ve read temp of 40°c on floors and they have been ok. Just make sure the correct HT adhesive is used.

    If its just in that area you can use ardex high temp or uzin ke49 which can take up to 60 degrees
