Radiator Installation and Repairs


Problems with your radiators? We’ve identified three of the top questions customers have regarding their radiators to help you identify exactly what’s wrong.

My radiator isn’t working, what can I do?
If you have one radiator which isn’t working, but the rest of your central heating system seems fine, then it usually means that there’s trapped air in the radiator which is stopping the hot water from flowing through the pipes.

It’s a relatively easy fix. Grab a radiator key and a cloth, and then locate the valve. Use the key to ‘bleed’ the radiator by slowly turning the valve until you can see air being released – usually accompanied by some water droplets. As soon as the droplets become a steady stream of water, close the valve and wipe down any damp areas.

If this still doesn’t resolve the issue, then it may be a problem with the thermostat on the radiator, which would require our help

Why aren’t my radiators getting hot?
If none of your radiators are heating up, it is probably an issue with your boiler. Check that it’s turned on, and that the thermostat is definitely set to the desired temperature. Also check the pressure indicator on your boiler. If it’s below 0.5 bar then you’ve lost some water in the system and it’ll need topping up – just find the water inlet valve and slightly open it to raise the pressure.

If this doesn’t work, or if you find that you’re needing to top up the pressure on a regular basis, then you’ve got a more serious issue on your hands and you’ll need our help to identify the issue and resolve it.

Why is my radiator hot at the top but cold at the bottom?
Radiators that are hot at the top but cold at the bottom usually have some blockages caused by sludge in the system. This happens over time as dirtier water causes a build up that can stop the pipes at the bottom of the radiator from flowing properly.

The solution to this is normally a power flush, which is carried out using a specialist machine and chemicals to break down any blockages. It’s recommended that you have a power flush of your entire system every 5 to 6 years to keep it working at its best, but if you notice issues then call us and we can investigate.
