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.
