commissioning ufh after tiling

[wdk]

Hi Folks
any advice welcome. To be clear the ufh was commissioned before floor was tiled (50m2 slate on Gyvlon) and has been down for a couple of months. This will be the first time the ufh is turned on since the tiles and grout were installed. Am I right that to avoid thermal shock I need to turn it up 5 degrees per day up to max temp, hold for a couple of days then down again?

cheers

Will

That will do yes, gradual increases as you say.

hi ,yes small gradual increases

[Mike]

and decrease the same rate when bringing it down

yes that is correct

Guys how long do you leave the UFH on in the periods of 'running in'

and what temp do you start at?
