WHAT FAILS HERE

Heating faults common in Leyton

Leyton's landscape of converted properties means we frequently encounter combi boilers that are perfectly functional but simply mismatched to the actual demand of the modernised living space.

01

Combi boiler struggling with simultaneous demand

In flats created from larger houses, the single combi boiler may be undersized for the number of hot water outlets, causing a noticeable pressure drop when a shower and kitchen tap are used at once. An engineer will check the boiler's flow rate against the property's requirements and assess the condition of the main cold water inlet.

02

Low hot water pressure in converted properties

Retrofit combi installations in older buildings can be hampered by existing pipework that is too narrow or partially blocked, restricting flow. The diagnostic process often involves testing dynamic pressure at various outlets and inspecting the internal boiler components like the plate heat exchanger for scaling.
