TESY Heat Pump Buffer Tank | 30L, 50L, 80L & 100L | Wall-Hung Insulated
TESY wall-hung buffer tanks are compact, high-performance buffer vessels designed for residential and light commercial heat pump systems operating in heating and cooling modes. Available in four capacities — 30L, 50L, 80L and 100L — they provide hydraulic separation and thermal storage to stabilise flow temperatures and improve overall system efficiency.
All models feature G1½" metal connections, INSUTECH insulation, thermo sensor pockets, and an air vent opening for safe, efficient operation. The 50L, 80L and 100L models include 4 or 8-port layouts for flexible pipework configurations; unused ports can be blanked off where fewer connections are needed.
Each tank is designed for vertical wall installation with an integrated mounting plate (100L includes a wall bracket; fixings not included). Optional upgrades include anti-condensation insulation on fittings and an electric heating element.
