What it is
The Gledhill Platinum Int Exp Dir 150 is an internally sited expansion arrangement for the Gledhill Platinum unvented cylinder range. The Dir designation denotes the direct version of the cylinder, and Int. Exp. indicates that the expansion vessel is housed within the unit rather than mounted externally. It accommodates the expansion of heated water inside a sealed unvented hot water system so the cylinder can continue to operate at mains pressure.
Signs this part needs replacing
- Water discharging from the pressure relief valve or tundish as the cylinder heats up
- Repeated loss of system pressure or frequent topping up at the filling loop
- Hot water performance falling away once the cylinder is under demand
- Weeping, staining or corrosion around the expansion vessel and its connections
Before you order
- Confirm the existing cylinder is the 150 direct model and matches this unit
- Check whether the installation is arranged with an internal or external expansion vessel
- Read the cylinder data plate and any existing part number before ordering
- Confirm there is access to drain down and recharge the system safely
