Boiler Efficiency & Performance FAQs
Maximise your boiler’s efficiency and cut energy costs. Our engineers explain how to improve performance, reduce waste, and stay safe.
What affects my boiler’s efficiency?
Age, servicing frequency, water pressure, and sludge build-up all impact boiler performance. Regular maintenance keeps efficiency high.
How can I make my boiler more efficient?
Bleed radiators, balance heating, install a magnetic filter, and service annually. Smart controls also help reduce wasted energy.
Do modern boilers really save money?
Yes. New condensing boilers are up to 90% efficient, saving up to £300 a year on gas bills compared to older non-condensing models.
What’s the best temperature for efficiency?
Set your flow temperature to around 60°C. This helps condensing boilers run efficiently while still providing enough heat.
Should I replace my old boiler to improve efficiency?
If your boiler is over 12 years old or rated below 80% efficiency, replacement can dramatically reduce gas use and running costs.
