Quick summary: A radiator staying warm after the heating is switched off is often caused by residual heat or slow circulation, but in some cases it points to a valve or system issue. The difference us...
It’s a common situation where a radiator feels warm to the touch, yet the room never properly heats up. On the surface, it looks like the heating is working, but in practice the warmth just isn’t spre...
A radiator that stays warm after the heating has been switched off can be confusing, especially when the rest of the system has already cooled. It often feels like the boiler is still running in the b...
When a radiator is warm at the top and bottom but noticeably cooler through the centre, it usually means heat isn’t circulating evenly across the panel. This pattern is less common than cold tops or c...
If your radiator is hot at the top but cold at the bottom, the most likely cause in a UK heating system is sludge buildup settling along the base of the panel. That lower section is where water moveme...
If a radiator is hot on one side and cold on the other, the issue is almost always uneven water flow rather than a faulty radiator. In most UK homes, this happens when hot water enters the panel but c...
When a radiator is warm at the bottom but cold at the top, the room never heats properly. The boiler may be running and the pipes may feel warm, but the heat is not circulating through the radiator as...
When radiators heat up for 10–15 minutes and then slowly go cold, the heating system is failing to maintain circulation through the full cycle. This usually happens because water flow becomes restrict...
When a radiator only heats properly after other radiators are turned off, the issue is almost never the radiator itself. This behaviour usually means hot water is not circulating evenly through the sy...
If your radiator gives off a dusty or slightly burnt smell when the heating comes on, it can be unsettling — especially if it appears suddenly at the start of cold weather. In most UK homes, this smel...
