Radiator hot but room cold

King Mallie · 06-02-2014 08:49PM #1

Hi All,

Can you help me. The radiator in the kitchen is really hot when you touch it but it gives out no heat.
The wall has pumped insulation and the ceiling has double layer of attic insulation.

Should I replace the radiator ?
Did anyone have this problem before ?

Thanks

Does the rad have fins between the panels? Are these hot? Try increasing the water temperature a little. Check one of the taps isn't closed off too much either.

Is there a draft, it doesn't take much to extract the heat from an open area.

Does the radiator have a clearance of 6 inches from floor level?

If the rad has a cold spot in the centre it's blocked with sludge.

As jca posted, feel the bottom centre of the radiator when the system is hot. If this part of the radiator is cold but the top is hot, it could may well be sludged.
