No Hot Water but Heating Works in Kingston upon Thames
Hot water gone but radiators still warm? That points to a specific set of faults — and we diagnose them the same day across Kingston upon Thames and South West London.
Local engineers, same-day emergency response, fixed prices — from the team based right here in KT1/KT2.
No Hot Water but Heating Works for Kingston upon Thames homes
When heating works and hot water does not, the fault is almost always in the part of the system that only serves hot water: a stuck diverter valve on a combi, a failed hot water flow sensor, a scaled plate heat exchanger, or on a cylinder system a failed motorised valve, cylinder thermostat or immersion element.
Hard water across South West London scales combi plate heat exchangers steadily — lukewarm water that goes hot briefly then cools is a classic scaled-exchanger symptom.
When your boiler dies on a Sunday morning or a pipe bursts under the kitchen sink, the last thing you want is a national callout line dispatching whoever's "nearest" — sometimes an hour away. Maxfix Plumbing and Heating is based in Kingston upon Thames.
Areas of Kingston upon Thames we cover: Kingston town centre, Norbiton, Coombe, Canbury, Kingston Hill.

Frequently asked
Your questions, answered
Why is my hot water lukewarm but the heating fine?
On a combi that usually means a partially stuck diverter valve or a scaled plate heat exchanger. Both are common in hard-water South West London.
Is a diverter valve worth repairing?
On a boiler with years of life left, yes — it is a standard repair. On a very old appliance we will give you the honest comparison against replacement.
I have a hot water cylinder, not a combi.
Then we check the motorised valve, cylinder thermostat, immersion element and wiring centre — the heating side working narrows it down quickly.
