Cool patch in the centre of the radiator

Problem:

Sometimes you may get a cold patch in the centre of the radiator and not at the top (which signifies that the radiator needs bleeding).

Diagnosis:

This is usually caused by rust deposits inside the radiator that won’t allow for the proper circulation of water.

Solution:

The radiator will need flushing.  This means you should take it off the wall and clean it.

Call EPM to arrange a visit.

One radiator won’t warm up

Problem:

Just one radiator will not warm up

Diagnosis:

There are a few causes for this problem:

  • The valve on the radiator may be closed.
  • Thermostatic valve may not be set properly.
  • The radiator valve may be blocked by corrosion.

Solution:

If your radiators are blocked by corrosion then you will need to remove the radiator and flush it out.  In any of the above events it’s best to hire a professional to check.

Call EPM to arrange a visit.

Top of radiator is cool

Problem:

The top section of the radiator refuses to warm up.

Diagnosis:

This is almost certainly caused by an airlock that is preventing the water circulating fully.

Solution:

The radiator will need to be bled to release any trapped air.  It’s really best to have an expert doing this for you because excess radiator bleeding can lower the pressure in your heating system.

Radiators won’t warm up

Problem:

Radiators won’t warm up but boiler is working properly.

Diagnosis:

If the boiler is functioning properly then there may well be a problem with the pump.  This pumps the hot water from the boiler around the house.  This may be due to the pump outlet being blocked, or the pump may not be working at all.  Another reason may be that the pump thermostat or timer is set incorrectly

Solution:

Call EPM to arrange a visit.

Radiators in part of the house don’t get warm

Problem:

Radiators in one part of the house don’t warm up.

Diagnosis:

This could be caused by several things.  The timer or thermostat that controls that part of the home may not be set properly, or it could be faulty.  This could also be a faulty zone valve or even a faulty pump.

Solution:

Call EPM to arrange a visit.
