Radiator not heating in Herefordshire? Here's what to do.
A cold radiator while others are warm is one of the easiest plumbing problems to diagnose — usually air at the top, or sludge at the bottom.
Try this first
Safe steps you can take in the next 10 minutes — in order.
- 1Bleed the radiator with a bleed key — turn the valve until water (not air) comes out.
- 2Re-pressurise the boiler if the gauge dropped after bleeding.
- 3If the top is hot but the bottom is cold, you have sludge — needs a power-flush.
- 4Check the TRV — sometimes the pin sticks; gentle tap with a wrench can free it.
When to stop and call
If bleeding doesn't help, multiple radiators are cold, or you find the bottom is cold but the top is hot (sludge needs professional flushing).
Likely causes
Most cases of a radiator that won't heat in Herefordshire homes come down to one of these.
- Air trapped at the top of the radiator — needs bleeding
- Sludge at the bottom restricting flow — needs flushing
- Stuck thermostatic radiator valve (TRV) pin
- System imbalance — newest radiator getting all the flow
- Failed pump (when ALL radiators are cold)
