My Boiler Won’t Reset: Is It Time for a New One?
If your boiler won’t reset, it may indicate a deeper problem that simple troubleshooting can’t fix. Persistent error codes, faulty components, or recurring system failures are common culprits. First, consult a qualified heating engineer for a thorough diagnosis. Sometimes, a minor fix, like replacing a sensor, can solve the issue. However, if your boiler is old, frequently breaks down, or repair costs are mounting, it might be more economical to invest in a new, energy-efficient model. Assessing the age, repair frequency, and costs can help you decide whether to repair or replace your boiler.

Regular maintenance can prevent many issues:
– Annual Servicing – Schedule annual servicing by a qualified professional.
– Monitor Water Pressure – Keep boiler pressure between 1 and 1.5 bars.
– Check for Leaks – Regularly inspect boiler and surroundings for leaks.
