Non-potable hydronic heating expansion tanks

HWB-24LX

The HeatWave™ Tank 24 liter / 6.34 gallon inline model is tailored for medium-capacity closed-loop heating systems. Its high-grade butyl diaphragm and patented chromed steel water connection ensure excellent fluid expansion management. The brass air valve, sealed with an O-ring, provides maintenance-free performance for years of operation.

Coated in a Gray dual-layer polyurethane finish, this tank is built to withstand challenging indoor and outdoor conditions. Supporting pressures of up to 0.7 bar / 10 psi, its inline design and 0.75" BSPT (c/w NPT) connection allow for seamless integration into hydronic circuits running glycol mixtures of up to 50%.
