FRESH is a combined buffer store for primary water with instantaneous production of domestic hot water (DHW) through a high efficiency heat exchanger made of a corrugated stainless steel pipe. It is available in two options: buffer store + DHW production (FRESH-1) and buffer store + DWH production and auxiliary heat exchanger (FRESH-2).

The high ratio between exchanging area and store volume, allows FRESH to deliver a high performance of DHW production even in combination with low temperature sources like the modern hydronic heat pumps Cylinders are also prepared to host a backup immersion heater (not supplied).
