Condensing boilers are more efficient than older models, but they have some specific failure points. The condensate pipe which drains the acidic water produced during condensing is vulnerable to freezing in cold weather, a problem we see regularly across Cardiff during winter. Flue issues and PCB failures are also common. We repair condensing boilers of all makes across Cardiff, usually on the same day. Call +44 7812 510121.
When You Need Condensing Boiler Repair
Watch for a fault code indicating a condensate blockage (often after a cold night), the boiler failing to ignite, error codes relating to the flue gas sensor, the boiler running but not heating properly, or the boiler locking out repeatedly. A frozen condensate pipe can often be thawed and the boiler restarted, but if it keeps happening the pipe installation may need improving.
Our Condensing Boiler Repair Process
We diagnose the fault using the boiler’s own error codes and our own diagnostic equipment. For condensate issues, we clear the blockage and assess whether the pipe routing needs improving to prevent recurrence. For PCB and component faults, we carry common parts for the most popular brands and quote for the repair before starting.
Condensing Boiler Repair Cost in Cardiff
Repair costs depend on the fault. Condensate clearing is a quick, lower-cost job. PCB or heat exchanger work costs more. We always quote before starting.
Why Choose Us
We repair condensing boilers across Cardiff throughout the year, with a spike in callouts during cold spells when condensate pipes freeze. We know how to fix the fault and improve the installation to reduce the chances of it happening again.
