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.
