So this weekend I started tiling my kitchen and finally finished on Christmas eve, it is around 20sqm on top of wet underfloor heating. The house was built in 2009.

I used 150mm x 600mm 8mm thick porcelain tiles and used tops tiles flexible adhesive and primed before hand with bal primer.

I tuned off the thermostat for the underfloor heating around 48 hours before I started tiling and I know I need to leave it off for around a week before starting to turn it back on.

My question is how should I do this. My heating system Is a nibe fighter exhaust air pump. The thermostats are not connected to the heat pump at all they are just connected to solinodes that are either open or closed to allow or stop the flow through the different room heating loops. The flow temperature is also variable as the heat pump uses temperature compensation from a outside temperature sensor to manage the flow temperature, For example the current outside temp is 5.8 degrees c the flow temp is 31 and the return temp is 29.

How should go about increasing the temp when it's safe to do so? There is a temperature compensation setting on the boiler if I reduce that the flow temp will lower in relation to the outside temperature. There flow temp never really gets that high anyway the most I've seen is around 37 I think during very cold weather.
