Only install the High Pressure Digital Mixer Valve with a multipoint gas water heater
or combination boiler of a fully modulating design (i.e. where the water draw-off
rate indirectly controls the gas flow rate to the burner).
An expansion vessel must be fitted (and regularly maintained) if any form of backflow
prevention device is fitted, e.g. Non-return valve or PRV. This will ensure that excess
expansion or pulse pressures do not damage the product or plumbing system. The
expansion vessel may already be fitted within the boiler (check with the manufacturer)
and is in addition to the normally larger central heating expansion vessel.
