Overview

The fluoCOLLECT accessory is a heat exchanger which connects to flexoTHERM 230V and 400V to adapt it to a water source heat pump. The water source adaptation, flexoTHERM with the fluoCOLLECT, can utilise onsite lakes, rivers and streams as a renewable energy source.

Using a fluoCOLLECT alongside a flexoTHERM enables end users to take advantage of consistent water temperatures, to produce consistent hot water and heating, even in the coldest of temperatures. With the water source system pipework being submerged, it is also a viable option for projects that are especially aesthetically sensitive and require minimal visual impact, during installation and once completed such as listed properties. Highly efficient with quiet operation, the flexoTHERM with fluoCOLLECT is a simple to install option for suitable projects.
