Chilly loft conversion

[Notcontent]

I had a loft conversion done recently and while it was done well, with insulation, it’s probably the coldest room in the house. I suspect it’s because it has large windows and I think the radiator may be too small for the space. Has anyone else had that problem?

It’s my dd’s room and she spends a lot of time sitting and doing homework, revising etc. So I am thinking of getting her an electric oil radiator as an interim solution, instead of turning up the thermostat for the whole house. Is that a good idea or are they very expensive to run?

They are expensive to run.
I'd bite the bullet and get a bigger radiator installed, not a big job they can extend the piping where the original radiator is.

Thanks. That’s what I thought…

One solution would be to fit wireless TRVs to all your radiators. That way you can control the temp in each room and don't have to have every radiator on to heat one room. Your daughter could have her radiator on whilst the rest of the house rads were off.

We spent about £800 installing our system and not only does it make the whole house more comfortable it reduced our heating bill by about 25%

We've got the same and have put an oil filled radiator in, it's cosy. We've put velux blinds in as well which help.

Surely with TRV's on every radiator you're going to be running the whole system more to heat one room?

We have put a much bigger radiator in one room as the existing radiator wasn't big enough. It absolutely solved the problem the room got nice and warm when the heating was on and we didn't have to run the heating longer or turn up the thermostat.

If you have wireless TRVs on every rad and run the heating system then the heat you produce will only be going to the rad(s) where the TRVs are 'on' - the other rads remains cold.

If you have a cold loft and you need a radiator on most of the time to keep it warm then it gets very, very expensive if you run this with electricity. Currently, electricity is 22p per KWh rising to 28p soon. Gas is currently about 4.5p rising to 7p.

Heating with Electricity is very, very expensive regardless of what method (underfloor, oil filled rad or boiler etc.) you use.

@TobyHouseMan thank you for the explanation.

How strange, our loft is roasting compared to the rest of the house.
Find a couple of radiator calculators online and check if your radiator is too small.

We had the opposite problem even though we had big windows the loft was the warmest room in the house. But did hale two radiators.

Another vote for getting a larger radiator.
We did this in our fairly large living room as it had one single small radiator. Got it replaced with a double depth one. It only looks a tiny bit bigger but the room is much cosier. I was surprised
We previously had loft conversion in our old house and struggled with the temperature extremes, heat waves were unbearable,.

I second for working out the BTU if the room (put the height, width and depth of the room into a BTU calculator online).
Then choose a radiator with enough of a BTU rating to heat it.
A wireless valve might save you electricity but it won't give the existing rad the capacity to heat the room..

Two moves ago our bedrooms were in the loft, freezing cold in winter and boiling hot in summer.
