Description
A higher capacity ensures a steady and sufficient flow and improves the operation and efficiency of the heat pump. A greater water volume also extends the duty cycles and, simultaneously, the life cycle of the compressor.
G-Energy buffer tanks are available as 501L and 1000L models, with DN50 and DN65 connections and 3 or 6 bar pressure categories.
