What it is

The Navien 3-way valve, part number 30015234A, is a hydraulic component used in Navien NCB-CE ERP boilers. It directs water flow between the heating circuit and the domestic hot water circuit according to demand. It is fitted across both system and combination models in the NCB-CE ERP range.

Signs this part needs replacing

  • Heating runs but domestic hot water does not, or the reverse
  • The valve body does not change position when demand switches between heating and hot water
  • Water passes to the wrong circuit, giving warm radiators during a hot water draw-off
  • The valve motor turns but the valve does not seat or seal correctly
  • Leaks or scale build-up around the valve body

Before you order

  • Confirm the boiler model and serial number against the fit list above
  • Check the existing valve part number before ordering
  • Inspect the valve body and actuator to confirm which component has failed
  • Confirm whether the boiler is a system or combination variant
