18 Litre Heating Expansion Vessel

Incorporating a welded hex nut connection, HeatWave tanks are easy to install. The air chamber is sealed with a brass air valve and O-ring sealed air valve cap providing many years of leak-free and service-free life. Its dual layer polyurethane paint finish will withstand the harshest indoor and outdoor climates throughout the world. HeatWave tanks are quality tested at several stages on the production line to ensure the structural integrity of every tank. HeatWave inline models are designed to be installed on system piping and supported by the GWS universal wall-mounting bracket. The expansion tank, pipes, and its connection, if installed incorrectly, could leak water. The expansion tank must be connected to the closed loop circuit and should only be used in close loop circuits with correct levels of corrosion inhibitor. Do not connect in an open-loop circuit or where fresh water can be used as a regular top up. HeatWave tanks are intended for use in closed-loop systems and should never be installed in open loop or potable water systems. Failure to comply could result in tank failure and subsequent property damage.
