1st switching on of UFH

[Dan]

I would yes.

I used to say turn it on to the temperature that matches the existing floor temperature, leave it 24 hours, turn it up a degree, leave it another 24 hours, keep doing that until the floor isn't heating up anymore no matter what temperature you set it to (meaning it's reached its max - you can also make a note of that temperature then too which can help you use it economically by not turning it up to that temperature all the time). Then bring it back down a degree per day until you hit the lowest temperature again.

Then use it as you wish. Should take a few weeks to do that, so you'll be doing the floor some good getting it slowly used to the heating and cooling.

Heard a few different ways of doing it. But I've never heard of just turning it on to its lowest for a few days then using it as you wish. Surely that's going to give the floor a bit of a shock wehen you suddenly whack it up to full?

SLC / adhesive can be shocked if turned on too much too soon. I always advise my clients to establish existing floor temp and as Dan says, start here. I get them to set temp adding 1 degree per day to max, then down again. I have lost count of the number of clients who inform me via email "our new floor is lovely and warm!".....only 12 hours after I leave the house :yikes: Never been back to a failed job yet though :lol:

Please dont do it though......there is a first time for everything

12 hours is a bit dodgy! Products will have cured but not actually dried out much then. So you'd be forcing them to try, which can ruin their strength. And that might not fail now. But in a couple of years time.

How many threads have we seen that start "UFH has been down 18 months now and cracks are starting to appear in the grout and a tile has come loose"....
