Put simply a heat pump takes the available heat from the ground or air surrounding a property and increases it to a more useful temperature for use in the home. This renewable source of heat can be used to create warm air or water (for space and central heating) as well as hot water (for both central heating and domestic hot water supply).
Air Source Heat Pump
Air-to-water heat pump
Quiet operation makes it suitable for use in densely built-up terraced housing estates
Particularly powerful – with a flow temperature of up to 75°C
Suitable for all applications
Super low GWP due to natural refrigerant
Discover a future-proof solution today that is both powerful and environmentally friendly. The new aroTHERM plus uses the natural refrigerant, R290 to achieve higher flow temperatures of up to 75°C. Suitable for all applications this air source heat pump can use existing radiators and operates down to -25°C.
The aroTHERM plus can be tailored to the properties needs with a choice of indoor units.
The uniTOWER is an integrated 190 litre cylinder with hydraulic components which can easily provide sufficient hot water for the needs of a family of five, including the use of rain showers. Thanks to its space-saving dimensions, the system is the perfect choice for new buildings. Installed indoors, the uniTOWER is about the size of a fridge freezer and saves valuable space in the room where it's installed.
In the case of higher hot water demand, the aroTHERM plus can be used together with a wall-mounted hydraulic station and a wide range of accessories, including the uniSTOR heat pump cylinders and buffer tanks.
Very Quiet Operation
The aroTHERM plus Sound Safe System ensures that it is hardly audible during operation. With sound power as low as 54dB(A) the aroTHERM plus 3.5, 5, 7 and 12 kW outputs have been accredited with the Quiet Mark. The system can be placed close to a residential building, even in densely built-up areas.
Suitable for Retro Fits
The aroTHERM plus is suitable for use with underfloor heating, fan coils and radiators.
The aroTHERM plus works with the environmentally friendly R290 refrigerant, which has a particularly low global warming potential and is therefore exempt from the EU-wide F-gas regulation. In this way, you can safely use the heat pump solution over the long term.
Your customers will be interested not only in the eco-friendliness of the technology, but also in its climate-friendly energy consumption. The system can be combined with photovoltaic or solar heating systems, among others, and helps your customers to reduce their own CO2 consumption.
Efficient & Economic Energy Consumption
With a SCOP up to 5.03 the aroTHERM plus is highly efficient. The system delivers up to 25% more hot water and can be used with rain showers. It’s high performance also makes the aroTHERM plus particularly economical: testing has seen up to a 43% saving when replacing oil or LPG heaters in retrofit projects.
*The achieved or achievable energy savings depend on various factors (e.g. local electricity prices, previous model, heating setting, use, location, outdoor temperature) and may thus vary
Ground Source Heat Pump
230V and 400V ground source heat pump with Green iQ technology
MCS accredited and Quiet Mark approved*
Suitable for domestic and commercial properties
ErP rated A+++ when installed with VRC 700 or VRC 700f
High seasonal SCoP value
flexoTHERM can be connected to either a ground collector or borehole system to provide efficient generation of heating and hot water.
This option is suitable for applications where adequate space is available to incorporate a ground collector - or a borehole in situations where space may be restricted. In addition, flexoTHERM can be connected to a passive cooling module to assist with climate control in modern homes that are airtight. The passive cooling module works as a heat exchanger, removing the thermal energy stored in a building to discharge it into the ground. It is only suitable for homes with underfloor heating and fan coil systems and must work with a ground collector.
Passive cooling is possible at almost no cost with ground or water sources, passing warm heating circuit water against cool brine fluid to gently cool down the building.
