We didn't heat the bedroom but our heavy breathing was causing so much condensation to form that below the window had to be painted. Heat it up a bit and the condensation is no longer a problem. I could probably reduce its use if I closed the bedroom door but then less fresh air.
We run the underfloor in the lounge all the time - but again thermostat on 15-18C and it gets lots of sun warmth.
Heated towel rail in bathroom is on all the time (can't see a thermostat for it so no idea what temp it's at).
Our hot water is now a small unit, much like an elec shower. This probably chews juice but I don't use hot water.
Hmm, it's probably just jacked up because of the heating being on now.
Not sure about the state of insulation.
We don't heat the bedroom/office/hallway. Just have the underfloor heating in the bathroom and kitchen on for a bit in the morning and a bit in the evening, then whack on one of the wall heaters in the living room while we're in there. Works fine. Not a big flat, and quite new and well insulated.
