Radiators don’t just keep your home warm - they can quietly inflate your energy bills if they’re not running efficiently! Here are a few simple, practical tweaks that can save you up to £100+ per year on your heating costs, especially during colder months:

Balance Your Radiators

Ensuring that your radiators are balanced can improve efficiency and reduce energy consumption. Balanced radiators distribute heat evenly, preventing some from overworking while others remain underutilised.

It’s a one-off job you can do yourself using free online guides - and it could cut your energy waste by up to 10%, saving around £60 annually in larger homes.

Install Thermostatic Radiator Valves (TRVs)

Fitting your radiators with TRVs allows you to control the temperature of individual rooms, reducing unnecessary heating and lowering energy bills.

Installing TRVs could reduce your heating bills by £70 a year, according to the Energy Saving Trust. Best Heating’s radiator valve guide is a great starting point if you’re unsure which type to get.

Bleed Your Radiators Regularly

Trapped air can prevent radiators from heating efficiently. Bleeding them helps your heating system run more efficiently - and could shave 5 - 10% off your energy use. This simple maintenance task can make a significant difference in energy consumption.

By selecting the right radiator style and implementing these money-saving strategies, you can enhance your home's comfort and efficiency without overspending.
