What it is
The Vaillant 0020020018 is a 13-plate domestic hot water (DHW) heat exchanger made of copper, fitted to Vaillant ecoTEC Pro 24 and 28 boilers. It transfers heat between the boiler's primary heating circuit and the domestic hot water supply to provide hot water at the taps.
Signs this part needs replacing
- Reduced or fluctuating hot water temperature at the taps
- No hot water despite the boiler firing for heating
- Kettling or unusual noise when hot water is drawn
- Scale build-up visibly restricting plate flow (where the part has been removed for inspection)
Before you order
- Confirm the exact VUW model/GC number of your boiler against the compatibility list
- Note the older part number 20020018 is now 0020020018 — check which your boiler's parts list shows
- Fitting must be carried out by a Gas Safe registered engineer
