Hyco spares and replacement parts
Hyco makes Speedflow point-of-use water heaters and the Zen boiling water tap range. On Speedflow heaters, the expansion vessel and valves that protect the sealed system are the parts that need replacing over the life of the unit. We stock genuine Hyco parts with trade pricing and same-day dispatch on stock items.
What we stock, by part
- Speedflow expansion and valve kits: the SF3 2 litre expansion vessel and check valve, and the SF4 expansion vessel, check valve and pressure reducing valve kit.
- Pressure reducing valves: the SF5, which keeps incoming mains pressure within the heater's limits.
- Zen fonts with drain for Hyco boiling water taps, in black (ZENFB) and white (ZENFW).
Finding the right part
The Speedflow kits combine different parts, so check which components your heater needs before ordering, and match the part number on the item you are replacing. Our guide on how to identify the right water heater spare part can help, or use the parts finder or our Can't Identify Your Spare Part? service.
