Three signs your radiators are wasting energy and how to fix them

With the weather only set to turn colder and amid the worsening cost of living crisis, many of us are trying to find cheaper ways to keep our homes warm.

Many of us are trying to find ways to cut costs where we can, and while we're trying to use less energy, we could actually be wasting it if our radiators aren't working properly.

Thankfully, the experts at BOXT have explained some simple ways of checking if our radiators are working properly, and what to do if they're not.

Fixing a problematic radiator will not only stop energy being wasted, but it could bring our energy bills down, too.

How to identify if your radiator needs bleeding:

  • Your radiator is cold at the top
  • There are damp patches or condensation surrounding the radiator or above it
  • Your radiator makes funny noises when heating up

How to bleed your radiator:

Start off by turning your boiler on and allowing your radiators plenty of time to fully heat up. This way, you can easily identify which radiators need some TLC and which can be left alone.

Carefully have a feel around the surface of your radiators (without burning yourself) for any cold patches. If any make a funny noise when heating up, have patches that heat doesn’t reach or you notice a radiator is cold at the top, it is definitely worth bleeding them.

Once you’ve identified the radiators that need some attention, turn the heating off and allow the radiators plenty of time to cool down. If you attempt to bleed a radiator with your heating on, you risk hurting yourself with the hot air or water from your radiators. You don’t want any trips to A&E just from trying to bleed a radiator.

Bleed your downstairs radiators first, then move on to upstairs. Place an old towel and a container below the radiator valves to catch any liquids to protect your home from any dirty radiator water spillage.

Use an old cloth or thick gloves to twist your radiator key anti-clockwise and open the valve.

Don’t open your radiator valve completely or keep it open for too long. Turn the valve enough to hear the hissing noise of air escaping. Allow all the trapped air to escape until the sound stops and a steady stream of water starts to leak from the valve.

Wipe away any excess moisture or condensation once you’re done, in order to avoid any rust forming around your radiator valves.

Double-check that your efforts have paid off. Firstly, check your boiler pressure. It’s normal for your pressure to decrease slightly after radiator bleeding. However, for reference, it should be around 1.0 - 1.5 bars when switched off and can rise to around 2 bars when switched on.

If your boiler pressure appears fine, it’s time for a ‘heat test’. Boot up your central heating and have another feel of your radiators. All being well, there should be no more cold patches, meaning you and your family can feel the full benefits of a warm home and save some cash on your bills - it’s a win-win situation.
