We recently attended a rental property in Exeter city centre where the tenant was experiencing heating and hot water issues.

Following a full diagnostic, we identified multiple faults within the Baxi boiler that were affecting performance and reliability.

Scope of works

Full boiler diagnostic and fault finding

Replacement of diverter valve cartridge

Replacement of actuator head

Recharge/replacement of waterlogged expansion vessel

System repressurisation and balancing

Full safety and operational testing

Findings

The boiler had developed several common faults over time:

A failed diverter valve cartridge causing issues with hot water and heating switching

A faulty actuator head preventing correct operation

A waterlogged expansion vessel leading to pressure instability

These combined faults resulted in poor performance and unreliable heating.

Outcome

All faults were repaired, and the boiler is now operating efficiently, safely, and reliably. Heating and hot water were fully restored for the tenant during the visit.
