What it is

The Vokera 20043496 is a by-pass valve used in Vokera Mynute i20 gas boilers. It sits in the heating circuit and controls the flow of water around the boiler, maintaining a minimum flow rate through the heat exchanger when system demand falls. It is supplied as a boiler spare part for service and repair work.

Signs this part needs replacing

  • Boiler locks out or overheats when most radiator valves are closed
  • Poor or inconsistent heating output across the system
  • Water leaking from the valve body or its connections
  • Noise or vibration from the boiler on low system demand
  • Visible scale, debris or seizure inside the valve when inspected

Before you order

  • Confirm the boiler model is a Vokera Mynute i20
  • Check the part number on the existing valve or the manufacturer's parts list
  • Inspect the valve seating and connections for damage before fitting
  • Isolate the boiler and drain down before removing the old valve
