Common Boiler Issues and Diagnostics in Balham
Boiler repairs in Balham (SW12) can be complex due to the diverse nature of modern heating systems. Whether you have a combination or a system boiler. Pinpointing the exact cause of a breakdown requires expert diagnosis.
Expert Troubleshooting for All Components
Many of the calls we receive for boiler repairs in Balham involve common mechanical or electrical failures, such as:
-
Faulty Diverter Valves: This often results in a total loss of hot water or causes radiators to heat up even when only the hot water is turned on.
-
PCB Failures: The Printed Circuit Board (P.C.B) is the “brain” of your boiler. If it fails, it can cause the fan to malfunction. Gas valve to stay shut. Circulator pump to stop working.
-
Complex Electrical Issues: Sometimes a component isn’t actually broken, but the P.C.B is failing to send the necessary power to it.
Our Transparent Repair Process
We use advanced electrical testing to determine which parts are truly faulty. In some rare cases—even after consulting manufacturer technical departments—diagnosing multiple failing parts can be difficult.
At Aquaheat, we believe in total transparency. We will always fully explain our findings and potential costs before we head to a supplier for parts. If a repair is no longer cost-effective due to the age or condition of your unit, we will provide a free, no-obligation quote for a boiler replacement so you can make the best decision for your home.
