  1. Bleed Your Radiator

There are a number of great online guides to help walk you through bleeding a radiator so whether you are looking to catch up on some old skills or are a complete beginner you should find the help you need.

If you find that your radiator has cold patches it could be that there is a build-up of air, and bleeding your radiator will ensure that the hot water can reach every part of the radiator.

To bleed your radiator you will need to open the valves at the bottom, and it is also worth pointing out that you may want to make precautions for any drips so you don’t ruin any flooring beneath the radiator.

You will then need to attach the bleed or vent key which can be picked up very cheaply at your local DIY store. When turning you should hear a hiss as the air escapes and you should re-screw the vent when water begins to escape.

This is more a tip for when you are having your radiators installed as it is quite common for flow diverters to be missed during installation.

  1. Balancing Your Heating System

It could be that you need to balance your heating system and ensure all of your radiators have their water flow adjusted to run at equal temperatures.

Of course some of these vary in difficulty but having some idea of what the problem is will definitely make it easier for you to solve.
