Two Boiler Buttons Could Save You £325 a Year on Energy Bills
- Adjusting flow temperature dials can improve boiler efficiency
- Heating should be set at 70°C, and hot water at 60°C
- Combi boilers account for 80% of UK homes
A boiler expert has revealed that adjusting two buttons on your combi boiler could help you save up to £325 a year on your energy bills. Combi boilers, which provide both heating and hot water from a single unit, are common in UK households but often run inefficiently due to incorrect settings.
What Are the Buttons?
Combi boilers have flow temperature dials that control the temperature of water for:
- Central Heating: Should be set at 70°C.
- Hot Water for Taps: Should be set at 60°C.
Why It Matters:
According to Ian Palmer-Smith, heating service director at Domestic and General, many boilers come with these settings incorrectly calibrated, causing them to use more gas than necessary.
How to Adjust:
- Locate the two dials or buttons on your boiler, typically labeled for heating and hot water.
- Set the heating flow temperature to 70°C and the hot water flow temperature to 60°C.
- Check your boiler’s manual or consult a professional if unsure.
Expert Insight:
Ian Palmer-Smith explained: “If your boiler isn’t set to the right temperatures according to the manufacturer’s instructions, it can negatively impact efficiency. Making these adjustments ensures your boiler uses less gas and reduces energy waste.”
