When hot water is running but your radiators stay cold, it's a classic sign of a partial boiler failure—a problem that London landlords and homeowners cannot afford to ignore. With strict obligations under the Landlord and Tenant Act 1985, failure to provide adequate heating can lead to fines, repair claims, or tenant complaints.
Fraser Bond, a leading London property consultancy, offers expert guidance and access to certified heating engineers to help property owners resolve heating issues swiftly and in full compliance with UK regulations.
If your boiler is producing hot water but not circulating heat to radiators, there are several likely causes:
In combi boilers, the diverter valve controls the flow of hot water between taps and radiators. If it's stuck or malfunctioning, your taps may work while your heating doesn't.
A common fault in central London flats is pressure loss due to radiator leaks or air in the system. If pressure is below 1.0 bar, your heating system may shut down.
If the thermostat or programmer isn't communicating correctly with the boiler, the heating circuit may not activate—even if the hot water remains functional.
Trapped air or sludge buildup can prevent water from circulating through radiators. This is especially common in older properties with poorly maintained heating systems.
