Energy specialists have issued a direct warning to UK households about a common winter heating habit that is driving up bills and reducing warmth. The advice, aimed at those trying to save money, suggests that the instinct to switch the heating on only in short bursts may be counterproductive.
The Problem with 'On and Off' Heating
According to experts at Grant Store, modern central heating systems are engineered for optimal performance when they operate at a consistent temperature. The practice of frequently turning the heating on and off forces the system to work much harder.
"When you switch your heating on for short bursts, the system has to work harder each time to reheat the property," the Grant Store team explained. "That process uses more energy than maintaining a steady, moderate temperature."
This constant cycle of reheating a cooled-down home is less efficient overall. Letting the interior temperature drop significantly means your boiler or heat pump must run for a longer period to restore comfort, consuming more fuel in the process.
Consequences for Your Home and Wallet
This inefficient pattern doesn't just hit your energy budget; it can also impact the heating system itself. The specialists highlighted that frequent short cycles contribute to increased wear on key components.
"Frequent short heating cycles can lead to wasted energy and more wear on system components," the team stated. "This can make your heating less reliable over time and increase maintenance costs."
The core message is clear: maintaining a stable indoor temperature generally requires less energy than repeatedly heating a home from a cold state.
How to Heat Your Home Efficiently
So, what should households do instead? The experts recommend a more consistent approach. Using a timer or a smart thermostat is still encouraged to reduce heating when you are asleep or out, but the key is to avoid letting your home get completely cold.
"Use a timer or smart thermostat to reduce heating when you are asleep or away, but avoid letting your home cool down completely," they advised. "Steady heating is more energy efficient than turning it on and off in short bursts."
They also emphasised that home insulation plays a critical supporting role. "A well-insulated home retains heat for longer," said the Grant Store team. "Sealing gaps around windows, doors and floors means you can use your heating less while staying just as warm."
In conclusion, combining a consistent, moderate heating strategy with effective insulation is the most effective way for households to stay comfortable while avoiding unnecessary energy waste and higher costs this December.
