Hello, Recently moved into a house that had a 3rd gen Nest installed, sync'd to my phone fine, but I can't seem to get the house temp above 18c. It fires up the boiler fine in the morning to get the house upto 18, but then cuts off. we've had the temp on the nest set to 25 just to try and get the temp up, but nothing doing now. I don't even get the 2+ hours. Any help would be greatly appreciated!!
