BUNSEN AIR SOLAR 
ASSISTED HEAT PUMP

The Bunsen Air Unit is a small solar assisted heat pump that uses 2 solar collector panels to transfer the FREE energy from the air and outside weather in order to generate energy in the form of heat. This energy is then transferred from your solar assisted heat pump to your domestic hot water system. The Bunsen Air unit is a Solar Assisted Heat Pump and uses externally fitted solar collector panels to transfer the free energy from the outside weather in the form of heat to the refrigerant.

An Air Source Heat Pump uses a large fan to blow air in order to transfer energy only from Air temperature. A Ground Source Heat Pump uses pipes in the ground to transfer energy from the earth. The Bunsen Air uses the two solar collector panels – which have no moving parts – to transfer energy from the FREE energy from the outside air temperature, wind, sunshine, rain or snow on the large surface area of the solar collectors to your hot water system.

The Bunsen Air solar assisted heat pump is the culmination of over 12 years of Research and Development data and has been designed to optimise power, efficiency and reheating capacity for all year round performance in the U.K. climate. 

The Bunsen Air solar assisted heat pump components are all specified for efficiency, ensuring the Bunsen Air solar assisted heat pump is a very low energy system which can provide all of your domestic hot water needs all year round. The Intelligent Controller Functions give you easy options to more advanced settings for operating your Bunsen Air unit and increasing the efficiency of you hot water system. 

The full development for the Bunsen Air unit has been carried out to optimise performance specifically for the U.K. climate. This very clever solar assisted heat pump will work in the coldest weather to produce your domestic hot water system needs day and night. Every internal component is dedicated to creating high level efficiency for the generation of domestic hot water, and protecting operational efficiency in the coldest weather. 

Slim Attractive Design - The Bunsen Air solar assisted heat pump unit shows its quality from the outside in. The modern design puts the Bunsen Air solar assisted heat pump unit into a class of its own in terms of aesthetics, and the touch screen display is elegant and simple to operate. Being a slim unit makes it ideal for wall mounting in tight spaces, while the looks make it pleasing wherever you choose to site it. 

Powerful Functionality - The Bunsen Air solar assisted heat pump has an extremely efficient and powerful compressor, with a small intelligent water pump to minimise running time and therefore costs, while maximising reheat times. The intelligent electronic valve system allows the Bunsen Air solar assisted heat pump to constantly monitor and manage all aspects of its performance throughout the heating cycle.

Audible Alarm System - The Bunsen Air solar assisted heat pump will let you know if any factors are affecting its performance. An audible alarm will sound to let you know there may be an issue. At the same time the intelligent controller system will automatically switch to immersion heater operations to ensure continuation of your hot water system and give you total support when investigating any possible issue. Therefore the Bunsen Air solar assisted heat pump can backs itself up should anything interfere with normal performance. 

Automatic Performance - The Bunsen Air solar assisted heat pump unit will heat your hot water 24 hrs a day the whole year around. If you wish to do so you can simply set the unit on the default settings, which will always heat your water back to 55°C as soon as it detects a 5°C drop in the cylinder temperature. Once the target temperature of the cylinder is reached the Bunsen Air solar assisted heat pump will switch itself off. This means you can always have hot water from your hot water system whenever you need it. 

Intelligent Controller Functions - The Bunsen Air solar assisted heat pump has further advanced setting options, allowing you to program when the Bunsen Air solar assisted heat pump unit does or does not operate, and even adjust the target temperatures within these operating times. You can program up to 3 operational time zones with 3 different target temperatures. This means that if you like silence only during specific hours of the night, you can make sure the unit cannot switch on. Or if you wish to prioritise daytime running when the Bunsen Air unit is even more efficient, you can chose Run Zone times and temperatures to get your greatest domestic hot water heating requirements during the warmer daylight hours. 

Automatic Anti-Legionella Function - The Bunsen Air solar assisted heat pump is programmed to heat the cylinder up to 60°C once a week for disinfection and Anti-Legionella protection of your domestic hot water system. This can be set to be achieved either by the Bunsen Air unit, or by both the Bunsen Air unit and the immersion. The day and time can be adjusted, although Friday mid-afternoon is generally a good time so there is even more domestic hot water waiting for you at the end of the week when you get ready to go out on the town!
