Avoid These Common Boiler Mistakes That Drive Up Heating Bills

With energy costs still a concern for many households, avoiding common boiler mistakes can help keep heating bills under control. Energy experts at Grant Store have shared the most frequent errors they see and how to fix them.

“One of the biggest mistakes is not getting your boiler serviced regularly,” say energy experts at Grant Store. “A service once a year ensures your boiler is working efficiently and helps prevent costly breakdowns during winter.”

Incorrect thermostat settings are another common issue. “Many households set the thermostat too high, which wastes energy and money. For most homes, a comfortable range is between 18°C and 21°C,” the experts explain.

They also warn against ignoring the boiler pressure gauge. “If the pressure is too low or too high, your system will not run as efficiently. Check your boiler manual for the correct range and adjust accordingly.”

Bleeding radiators is another simple yet often overlooked step: “Trapped air in your radiators can stop them heating properly, which makes your boiler work harder. Bleeding them in early autumn can improve efficiency before the cold weather arrives.”

The experts also recommend checking your heating schedule. “Setting the heating to come on only when needed and turning it off when you are out can make a big difference to your bills. Many smart thermostats allow you to programme heating times to match your routine.”

Finally, they suggest keeping the area around your boiler clear. “Storing items too close can block ventilation and reduce efficiency. Always make sure there is enough space around the boiler for it to operate safely and effectively.”
