Central heating & 3 storey house

kitch

Hi. Just after a bit of advice. Trying something new with the heating this winter.

Usually we normally have all the radiators switched on full (when needed of course) and the thermostat on about 22. Problem is that the bottom floor is quite cold. For us to be able to warm the bottom floor enough, we have to ramp up the thermostat to 25 or so. The rest of the house then gets far too warm.

This year I have switched off all the radiators other than the bottom floor and leave the thermostat at about 25/26. When the heating comes on, it warms the bottom floor nicely and the heat rising gets the rest of the house comfortable.

Is it more expensive to do the latter as the temp is higher or is it offset by the fact that i only have one floor of radiators switched on?

Thanks for any help.

Presumably you don't have working TRVs on the radiators as that is the whole purpose of having them fitted.


Without knowing the insulation properties of your house and size of rooms etc, nobody can answer.


Your best bet is to attempt a trial for a week on each system when the weather is roughly the same.
