House partly unnocupied

[raebhoop]

I live in quite a large house with a Combi boiler,and because of ill health sleep downstairs on a bed settee.The bathroom is upstairs.
What's the situation in winter...can I turn off the upstairs bedrooms and landing radiators for long periods as I don't need them?...Or should they be kept turned down low?

You could turn the upstairs bedroom radiators down to the frostguard setting on the TRVs and keep the doors to those rooms shut, but since heat rises and there's unlikely to be much in the way of insulation between your downstairs ceiling and your upstairs floor (plus the big hole the stairs go up!) you might well find that your downstairs rads are then working twice as hard because they're still having to heat the whole house.

I doubt you'd save much in terms of total heating bills.

 

[Youllneverguess]

To an extent, big temperature differentials will encourage heat transfer.set your unoccupied areas to 15 degrees and close the doors. That will also minimise damp too.

And moisture in the air will condense in the colder rooms, causing mould potentially
