Description
Description
TESY Buffer Tank for Heat Pump System 50L | 8-Port is a compact buffer vessel designed to improve stability and efficiency in heat pump heating systems and other multi-source renewable setups. It provides reliable heat storage and hydraulic separation to help maintain steadier temperatures and consistent performance in both domestic and light commercial installations.
With eight ports (four inlets and four outlets) and robust G1 ½” metal connections, it offers flexible integration across a wide range of heat pump system layouts. It also includes two thermo sensor pockets to support accurate temperature monitoring and system optimisation.
To help minimise heat loss, the tank is wrapped in 34mm INSUTECH insulation and finished with a clean white metal jacket. An integrated mounting plate supports vertical wall installation, with additional safety via an AV opening and optional upgrades such as anti-condensation insulation on fittings and the ability to add an electric heating element.
Key features
This item must be installed by a qualified heating professional and specified correctly for your heat pump system design and flow requirements. Always follow the manufacturer’s instructions and ensure all fittings, valves, and safety components are selected to suit the system.
