Non-potable hydronic heating expansion tanks

HWB-80LV

The HeatWave™ Tank 80 liter / 21.13 gallon vertical model is built for demanding closed-loop heating systems requiring reliable fluid expansion management. It features a high-grade butyl diaphragm, patented chromed steel water connection, and a brass air valve with O-ring sealing for leak-free, long-lasting operation.

Coated in a durable Gray dual-layer polyurethane finish, this vertical tank is resistant to corrosion, making it suitable for a wide range of environments. Supporting pressures up to 1.5 bar / 22 psi, it is perfect for large-scale radiant heating circuits and glycol-based systems. The 0.75" BSPT (c/w NPT) connection simplifies installation.
