Replacing radiators - will this help make the room warmer?

[loziv]

Hi

In our living room which is approx 3.7m x 4.8m we only have the following radiator

under the bay window. Is this big enough for the room or would we be better with a more powerful and more efficient radiator?

Also in our hallway which is very large and the stairs lead up to a galleried landing, we have the following radiator

near to the front door

Again would we be better replacing this with a larger radiator or additional radiators? to make the house warmer / more efficient

Many Thanks
Lauren

If your current radiators seem to heat up the room to a satisfactory temperature on cold winter days then there is no need to replace them.

If not, they are most likely to be undersized, find out the correct size needed by doing a heat loss calculation.

Sometimes the radiators could be correctly sized but the system may be dirty or not balanced so the radiators don't heat up properly.
