Air Source Heat Pumps

Air Source Heat Pumps do not incur any civil ground work costs for the installation and laying of pipes. The cost of these works can be significant, but not for Air Source Heat Pumps. This can make this option advantageous over Ground Source versions.

Our Air Source Heat Pumps provide an alternative low cost solution for space heating and hot water. A typical return on investment against Oil and LPG fed heating systems can take as little as 5 years. Air Source Heat Pumps are also suitable for hot water and comfort cooling applications which provide a comprehensive solution for both domestic and commercial applications.

Air Source Heat Pumps also provide hot water from a pressurised system up to temperatures as high as 55°C which is very suitable for all domestic and business requirements. This will require a tank which is specified to the usage requirements of the tenants or usage of the building. The larger the tank the larger the output of water.

In some applications it may be appropriate to couple an Air Source Heat Pump with traditional heating technology to compliment the required outputs. All Eartheat Air Source Heat Pumps which are specified against user (domestic & commercial) requirements do not need any third party boosting system. The outside of a building is where the fan intake system (outdoor air handling unit) is fixed requiring no annual maintenance. The fan is the only moving part of the outdoor unit which requires no ongoing maintenance.

Air Source Heat Pumps take energy from the air and raise it to a higher temperature using a process which is similar to reversed refrigeration. For commercial and large spaces a row or bank of Air Source Heat Pumps (Air Handling Units) will be required along with internal heat pump and pressured hot water tank for ongoing water usage. This is a system which utilises no external pipes and most of the working elements reside within the building. The air handling unit draws air across the water-anti freeze solution and transfers this energy into the refrigerant. The refrigerant boils and the gases from this are compressed to produce temperatures in excess of 100°C. This part of the process mirrors a ground source heat pump. Air Source Heat Pumps can be used in many more applications including large commercial projects where land space is restricted. Air Source Heat Pumps can be used as a complete solution for room heating using the same distribution system as a ground source heat pump or a traditional system. Air Source Heat Pumps are ideal for very tight spaces and within an eco architectural design or within the design of a building which has large internal spaces such as audience halls and public places.

Eartheat Air Source Heat Pumps are unique as they have no major parts outside exposed to the elements, which means that the compressor and circulation pumps are all internal. The intake fan is the only feature which is external and kept at optimum working temperature with the support of an internal defrost cycle system ensuring 365 day operation in all seasons. The internal defrost system uses the hot water collected by the Air Source heat pump as opposed to direct electric. These types of systems can last in excess of 20 years. The recommended maintenance for the outdoor unit is simply to hose it down once a year. In costal areas this process should be repeated each season.
