A specialist from British Gas shared tips on resolving cold spots in radiators, suggesting using a radiator key that costs 97p. If your radiator has cold spots at the top or is slow to heat up, bleeding it may be necessary to release trapped air. It’s a simple task but requires the proper tool.
Before bleeding the radiator, turn off the heating system and allow the radiator to cool down to avoid burns. Have an old towel and container on hand to catch water. Locate the valve on the radiator, turn it anti-clockwise using the key, and listen for a hissing sound as air escapes. Catch the water in the container, tighten the valve, and move on to the next radiator.
Avoid turning the valve too much to prevent lowering the boiler pressure. If issues persist after bleeding the radiators, seek assistance from a gas safe registered engineer. Additionally, a British Gas engineer recommended leaving the oven door open after cooking to utilize residual heat and warm the kitchen. Energy bills have increased, with the average yearly cost for gas and electricity now standing at £1,758 for direct debit customers.
