NON-POTABLE WATER EXPANSION TANKS

17

HeatWave tanks are designed for use in closed-loop

hydronic heating systems and should never be installed

in open loop or potable water systems . They are the ideal

solution for fluid expansion in radiant heating systems and

can be used with systems running glycol with a water to

glycol mixture of up to 50% . The air chamber is sealed

with a brass air valve and O-ring sealed air valve cap

providing many years of leak-free and maintenance-free

life . Its two-part polyurethane, primed paint finish will

withstand the harshest indoor and outdoor environments .

HeatWave inline models feature a welded hex nut connection

and can be installed on system piping and supported by the

GWS universal wall-mounting bracket . Freestanding vertical

and horizontal models are constructed with a rigid base

designed to support the weight of the tank during operation

The expansion tank must be connected to the closed loop

circuit and should only be used in close loop circuits with

corrosion inhibitor . Do not connect to an open-loop circuit or

any system where fresh water is used for regular top up .

Available vertical and inline, ranging from 2 - 150 L /

0 .5 - 39 .6 G .
