Designed specifically for use with unvented cylinders, ThermoWave unvented vessels are ideally suited for domestic and light commercial applications where potable water is stored in an unvented cylinder and supplied to showers, taps etc.

This unvented expansion vessel comes with a bracket attached.

Traditional water heating systems rely on relief valves to allow water to be released from the hot water vessel when pressure becomes too high, which is highly inefficient. ThermoWave expansion vessels conserve water and energy by temporarily absorbing expanded water volume instead of allowing it to be vented through the relief valve.  Using water chambers constructed from high grade butyl diaphragms and virgin polypropylene liners, ThermoWave™ vessels ensure the potable water remains safe and hygienic.

As with all GWS products, these vessels are quality-tested throughout the production process to ensure their structural integrity, and are capable of managing a maximum working temperature of 90° C / 194° F.
