Is It Time to Replace Your Boiler?

To get the best performance from your heating system, your boiler needs to run efficiently. If your boiler is old, unreliable or frequently breaking down, it may be costing you more than you realise – and replacement could be the most cost-effective solution.

Modern boilers can operate at up to 90% efficiency, helping to:

  • Reduce energy usage
  • Lower heating bills
  • Improve reliability

 

Many new boilers also include manufacturer warranties of 8–12 years, offering long-term reassurance and excellent value.
