Leaway Posted October 27, 2016 Share Posted October 27, 2016 Help anyone, just been advised by one of the tilers providing a quote that the UFH system needs to be powered and tested prior to laying floor tiles to reduce the risk of cracking. The frame is MBC with MBC laid pipes but looking to get tiles / kitchen in asap but power not expected until early December so dependancies are creating a problem. 1) is cracking really a risk for this type of insulated floor? 2) is there a way to power test / heat cycle the UFH on temporary power? 3) Any other options / ideas?

Nickfromwales Posted October 27, 2016 Share Posted October 27, 2016 Guys just being massively over cautious. . No need to run it imho and I never have. Is your slab concrete with steel mesh or floating screed / other? Link to comment Share on other sites More sharing options...

Agree with Nick Very cautious When you do put your unf heating on Keep it at 20% for the first week gradually increasing each day after that If you want to be 100% safe of cracking or lifting Bed Dural matting down before laying your tiles Bit more expense But well worth it Link to comment Share on other sites More sharing options...
Leaway Posted October 27, 2016 Author Share Posted October 27, 2016 cheers guys. yes he is very prim and proper. What is 'imho' Nick? Floor is MBC epc with steel before pour. If i can't work out a way of getting the UFH on i'll take the risk as kitchen ordered and tiles need to be down before fitting. Does the dural matting affect UFH performance?

PeterW Posted October 27, 2016 Share Posted October 27, 2016 How long has the floor been down for and are there any expansion joints..?? IMHO - in my humble opinion... Link to comment Share on other sites More sharing options...
nod Posted October 27, 2016 Share Posted October 27, 2016 No the performance is the same I would put it down with all tiled surfaces with UFH Link to comment Share on other sites More sharing options...
Leaway Posted October 27, 2016 Author Share Posted October 27, 2016 the pour was completed in May 16 and building mainly weatherproof since June Link to comment Share on other sites More sharing options...
PeterW Posted October 27, 2016 Share Posted October 27, 2016 will be dry as a bone and any cracking would have happened by now. I'd just get tiling... 1 Link to comment Share on other sites More sharing options...
