Boiler Repair or 
Boiler Replacement?

Recognising when you require a boiler service versus a heating repair is vital. Boiler servicing, akin to a car’s MOT, is an annual check-up for safety, efficiency, and performance, including replacing specified parts as instructed by the manufacturer. Mainly, a boiler service is preventive, catching issues before they happen!

Boiler repair is a cost-effective option for minor issues that don’t impact the unit’s overall performance. However, if your boiler is over 10-15 years old, frequently breaking down, or significantly inefficient, investing in a new boiler replacement may be more economical and energy-efficient in the long run.

System Losing Pressure

If your boiler system is losing pressure, it could indicate a leak, faulty relief valve, or issues with the expansion vessel. Low pressure can compromise your boiler’s efficiency and heating performance.

Our best advice is to get the boiler and central heating system fully serviced, as this may produce clues as to what is causing the issue or eliminate the problem before the problem leads to a full breakdown.
