£5,694.30 inc. VAT
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.
Connect with a Standard Pre-Plumbed Cylinder for an eco-friendly, low cost hot water solution. With its sleek design and pre-plumbed architecture, the space requirements for the pre-plumbed hot water cylinder have been reduced dramatically.
• Hot Water Heating up to 75ºC
• Operates in Extreme Frost to -20ºC
• Sound Power @ 54dB(A)
What is a Air to Water Heat Pump?
An air to water heat pump is not a new technology is an electrical device that extracts heat from one place and transfers it to another. A heat pump is not a new technology; it has been used around the world for decades. Refrigerators and air conditioners are both common examples of this technology.
Heat pumps transfer heat by circulating refrigerant through a cycle of evaporation and condensation. A compressor pumps the refrigerant between two heat exchanger coils. In one coil, the refrigerant is evaporated at low pressure and absorbs heat from its surroundings.
What are the benefits of Air Source Heat Pumps?
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 fit change
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 and 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.
