A specialist from British Gas has shared advice on how to address cold spots in your radiator, with a low-cost tool priced at just 97p. If you notice cold areas on your radiator, particularly at the top, along with gurgling sounds and slow heating, it may be necessary to bleed the radiator. This process, though simple, requires the use of a radiator key, which can be purchased inexpensively from Screwfix.
Before starting the bleeding process, it is crucial to switch off your heating system. Ensure that the radiator has completely cooled down to avoid any risk of burns from hot water. Prepare an old towel and a container to catch the water that will be released during bleeding. Locate the small valve on the radiator and use the key to turn it anti-clockwise.
Peter Knowles, a technical repair engineer at British Gas, advises to open the valve slightly until you hear a hissing sound, indicating the release of trapped air. Once water starts to come out, collect it in the container, then tighten the valve and move on to the next radiator. Over-bleeding can reduce boiler pressure, so caution is advised.
If bleeding does not resolve the issue, it is advisable to contact a Gas Safe registered engineer for further assessment. Additionally, another British Gas energy engineer, Jessica Rawstron, suggests utilizing residual oven heat by leaving the oven door open after cooking to warm the kitchen and conserve energy.
Recent increases in energy bills have pushed the typical annual cost for gas and electricity to around £1,758 for households on direct debit. The price cap sets limits on unit rates and standing charges but does not cap the total bill, which still depends on actual energy usage. Pre-payment meter users now face a yearly cap of £1,711, while those paying upon receipt of the bill are looking at £1,894 annually.
