Potable hot water expansion tanks

ThermoWaveTM expansion tanks are specially designed for

use in potable water heating applications . Many homes

and buildings have potable water heating systems to

provide hot water for washing, cooking, showering, etc .

As the water is heated it also expands . This expansion

leads to increased system pressure and can cause serious

damage . In most systems a relief valve is installed to vent

the expanded water volume and prevent the system from

exceeding maximum operating pressure . Unfortunately,

this creates wasted energy as hot water is vented and

additional water must be filled and heated again . In

order to safely accommodate the natural expansion of

water without venting from a relief valve, a ThermoWave

expansion tank is used . ThermoWave expansion tanks

conserve water and energy while safely maintaining system

operating pressures . They do so by temporarily absorbing

the expanded water volume instead of allowing it to be

vented out of a relief valve .
