What does a heat pump buffer tank do?
A heat pump buffer tank increases system water volume, helping to reduce cycling, support defrost cycles and improve system stability.

Is a heat pump buffer tank the same as a thermal store?No. A heat pump buffer tank is primarily used to increase system volume and support heat pump operation, whereas a thermal store is designed to store larger quantities of thermal energy.

Do all heat pumps need a buffer tank?Not always. The requirement depends on the heat pump manufacturer’s recommendations, system volume, zoning arrangements and overall system design.

Can a biomass buffer tank be used with a heat pump?
In some cases, yes. However, a dedicated heat pump buffer tank is often a better fit where the primary objective is reducing compressor cycling and providing additional system volume.
