What it is

The Vaillant 065131 is a 190mm, 12-plate secondary heat exchanger used only in combi boilers, transferring heat between the primary heating circuit and the domestic hot water circuit to provide hot water on demand.

Signs this part needs replacing

  • Fluctuating or reduced hot water temperature at the taps
  • No hot water while central heating still functions normally
  • Unusual noise (kettling) when hot water is drawn
  • Scale-related restriction found on inspection

Before you order

  • Confirm the exact VUW model and GC number/revision (R1–R3) of your boiler against the compatibility list
  • Fitting must be carried out by a Gas Safe registered engineer
