Could Radiator Sludge Be Behind Your High Energy Bills?

If you’ve noticed your energy bills rising recently, this could be down to a number of reasons. The problem may lay with the boiler, your thermostat, or even your radiators.

Could Radiator Sludge Be Behind Your High Energy Bills?

Old Boiler

If your boiler is over 10 years old, it is quite likely that this is the cause behind your high energy bills. This is because the older your boiler gets, the less efficient it becomes.

According to The Energy Saving Trust, an A-rated boiler could potentially save you £315 a year. Click here for a fixed quote on a new boiler installation.

Boiler Pressure

If your boiler pressure has fallen, your boiler will require more fuel to reach the same amount of heat, therefore costing you more.

It’s quick and simple to top up the pressure and instruction on how to do so can usually be found in the manufacturers guide. Alternatively, you can read this helpful guide on how to top up your boiler pressure by iHeat.

You Aren’t Using Your Thermostat Effectively

Learning how to control your heating system’s settings to deliver optimum temperature in accordance to your lifestyle can also save you lots of money on your bills.

The Centre for Sustainable Energy recommends programming your boiler to turn the heating on 30 minutes before you wake up in the morning but at a lower temperature.

By reducing your room temperature by just 1°C, a change you may not even notice, you could potentially cut your bills by up to £75 a year in an average home. Public Health England suggests 18°C as the minimum temperature of your living room.

Your Home Isn’t Insulated

Almost a third of heat lost in uninsulated homes escapes through the loft/roof. Insulating your home can reduce this heat loss and save you up to £160 a year on energy bills.

Air Bubbles or Radiator Sludge

Air Bubbles or Radiator Sludge

When your radiators have cold spots, it requires more energy to heat the room up that it would if they are hot all over.

If your radiators are cold at the bottom, this is likely as a result of a build up of sludge. Whilst it is possible to clean them yourself, it’s usually better to get this done by a professional who can clean them properly or perform a powerflush.

If your radiator is cold at the top, it most likely needs bleeding. When people don’t turn on their heating for long periods of time such as during Summer, this can cause air bubbles to get trapped inside the radiators.

Because the bubbles rise, the air accumulates at the top of the radiator, making it gradually become cooler.
