A friend of mine has a small flat with a tiny hallway, he has a modern Worcester combi with a wireless thermostat and TRV's all round. When I visited recently I could hear the boiler cutting in and out fairly frequently without the living room really warming up. His hallway leads onto the buildings fairly cold hallway entrance via the front door I don't know if the rads have been balanced but what would be the best way of setting up the rooms TRV's and siting the thermostat? Thanks for any advice.
