What it is
The plate heat exchanger and 3-way valve assembly is an Alpha component for the He33 (LPG) boiler. It combines the domestic hot water plate heat exchanger with the 3-way valve that diverts boiler water between central heating and hot water modes. Both functions are supplied as a single assembly.
Signs this part needs replacing
- Domestic hot water runs hot and cold, or fluctuates in temperature
- No hot water while central heating continues to work
- Boiler fails to switch between heating and hot water modes
- Water leaking from the plate heat exchanger or valve body
- Reduced hot water flow caused by scale or debris in the plate heat exchanger
Before you order
- Confirm your boiler model is the Alpha He33 (LPG)
- Check the part number 3.018556 against the existing component
- Verify the boiler is the LPG variant, as fitment differs from natural gas models
