What it is
The Vokera 20196690 is a high head by-pass valve used in EASI-HEAT I combi boilers. It regulates flow between the heating circuit and the boiler's primary circuit, maintaining a minimum flow rate through the heat exchanger when system demand falls. This protects the appliance from overheating and helps keep temperature control stable.
Signs this part needs replacing
- Boiler cycles or locks out with an overheat fault
- Kettling or banging noises from the heat exchanger
- Radiators heating when only hot water is drawn
- Unstable or fluctuating domestic hot water temperature
- Valve body shows scale, debris or a stuck spindle
