How soon after plastering can I turn on heating?

[celine26]

Hi the plastering is almost complete in our renovation. We are installing underfloor heating powered by a geothermal heatpump. I was wondering how long we should leave it before the heating is turned on? We are keen to get it on asap but want to avoid cracks as much as possible.

When I replastered one room completely, I gave it three full days (in early summer) to dry out competely with windows open. I then only heated for short periods, and low temps.

Let it go as long as possible before you turn it on. On fine days, open all the windows in the room(s), as Horusd said.
