Overview

The fluoCOLLECT water-to-water stainless steel heat exchanger connects to a flexoTHERM heat pump to offer an alternative to ground source.

Water source heat pump systems are ideal for end users that have a suitable water source onsite, such as a lake, river or stream. 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.

flexoTHERM and fluoCOLLECT are MCS accredited, so may qualify for the RHI scheme.

Features and benefits:

  • Available in 230V and 400V - 230V heat pump is available in 5, 8 and 11kW models. 400V heat pump is available in 5, 8, 11, 15 and 19kW models
  • More power, more efficiency - Integrated EVI super compressor, injects additional refrigerant into the compression cycle
  • Exceptionally quiet - With noise levels as low as a modern refrigerator - 42dB(A), flexoTHERM has earned the ‘Quiet Mark’ approval.
  • High quality and sustainable - Green iQ technology aids in future-proofing the product and ensures optimum efficiency performance and sustainability.
  • Ability to cascade up to seven flexoTHERM heat pumps - Suitable for larger domestic and commercial properties.
  • Ideal for aesthetically sensitive projects - Minimal visual impact both during and after installation.
