flexoTHERM is a ground source heat pump out of the box which can be connected to either a borehole or a ground array for ground source applications. Using advanced EVI compressor technology, flexoTHERM earns the Vaillant Green iQ badge meaning flexoTHERM is the most efficient product in its range. When installed with a VRC 700 or VRC 700f weather compensating control the flexoTHERM becomes ErP rated A+++.
flexoTHERM has also been awarded "Quiet Mark", issued by the Noise Abatement Society, thanks to its exceptionally low operating noise levels. It sounds no louder than a standard domestic fridge of 42dB(A). flexoTHERM is MCS accredited and RHI eligible. flexoTHERM is the third heat pump to be awarded "Quiet Mark" alongside the aroTHERM air-to-water heat pump and geoTHERM ground source heat pump.
The ground source unit can also be connected to a passive cooling module for projects that require efficient climate control as part of the specification which works by passing warm heating circuit water against cool brine fluid to gently cool down the building.
