Potable hot water expansion tanks

TWB-8LX

The ThermoWave™ 8-liter / 2.11-gallon inline expansion tank is an ideal choice for compact potable hot water systems. Featuring a high-grade butyl diaphragm and virgin polypropylene liner, it ensures safe and reliable performance. The patented stainless-steel water connection provides a dual water/air seal, while the O-ring sealed air valve ensures leak-free operation.

Pre-charged to 1.9 bar / 28 psi and fitted with a 0.75" BSPT (c/w NPT) connection, this inline tank helps conserve water and energy by absorbing expanded water volume.
