GWS ThermoWave™ potable water pressure tanks are suitable for domestic and light commercial central heating applications such as washing, cooking, showering and more.

Traditional water heating systems rely on relief valves to allow water to be released from the hot water tank when pressure becomes too high, which is highly inefficient. ThermoWave™ expansion tanks conserve water and energy by temporarily absorbing expanded water volume instead of allowing it to be vented through the relief valve.

ThermoWave™ vessels are constructed with a virgin polypropylene liner combined with a high grade butyl diaphragm.

GWS expansion vessels are quality tested at several stages during production to ensure the structural integrity of every tank which guarantees a high quality, reliable vessel.
