What it is
The Vaillant 064724 is a 28-plate secondary heat exchanger that transfers heat from the boiler's primary circuit to the domestic hot water supply. It is fitted to Vaillant VUI 362-7 and Aquaplus VUI 362-7 appliances. The plate pack forms the DHW heating surface within the boiler.
Signs this part needs replacing
- Domestic hot water runs cooler than the set temperature or fluctuates
- Reduced hot water flow rate at the taps
- Visible weeping or leaks from the plate pack
- Scale or debris build-up restricting flow through the plates
- Kettling or unusual noise when hot water is drawn
Before you order
- Check the appliance data badge to confirm the model and GC number
- Confirm the existing heat exchanger has 28 plates
- Check whether new seals or O-rings are required separately
- Isolate and drain the appliance before removal
