How the Air Source Heat Pump Works

The Danfoss air source heat pump works by using the energy from the air around you and converting it into heat for your home or commercial property. They are also used to power cooling systems and work on a similar principal to a domestic refrigerator unit. Air has the ability to absorb and store solar energy from the sun, which is naturally replenished when used. Air source heat pumps can be over six times as energy efficient as gas or oil boilers. The popularity of solar panels is soaring at the moment but these can't provide you with central heating, whereas air source heat pumps can. It should also be noted that, instead of causing harmful emissions by burning fuel, they are simply moving solar energy that already exists from one place to another and are therefore completely environmentally friendly.

Air source heat pumps are now becoming just as popular as ground installations. They are quick and easy to install and almost as effective as the ground source systems. There is no need for drilling or digging, so disruption is minimal. If your property has little ground space, then this is the perfect alternative to a ground installation. Thanks to constant research and upgrades, the noise and vibration from these air source installations is no louder than the refrigerator in your home.

The Danfoss air source heat pump will work in the coldest weather conditions and has been proven to be completely suitable for UK winters. Domestic hot water is produced at a lower temperature than the average boiler system, which is more suitable for normal domestic requirements and puts a stop to unnecessary scalding hot water - you won't need to add lots of cold water to your bath. Danfoss designs are unique as almost all parts are internal, including organs compressor and circulation pump, so nothing is exposed to adverse weather conditions. The intake fan is the only external part of the system and this comes with its own internal defrost cycle system to ensure it is kept running at the optimum working temperature. The internal defrost system uses the hot water collected by the air source heat pump.

New Danfoss Design

The new DHP-AQ Danfoss air source heat pumps are capable of performing perfectly at temperatures as low as -20 degrees C. They are equipped with the highest new standards in defrosting technology. This new design range was developed in Scandinavia by Danfoss, who are world leaders in heat pump technology. Danfoss are expecting a high demand for these systems both commercially and domestically. In keeping with other Danfoss designs, the new DHP-AQ has been designed for simple installation by qualified heating engineers. These new systems are also said to be the quietest on the market at present.

The DHP-AQ comes in three design kits; mini, midi and maxi to suit the individual tastes of the customer as well as the requirements of the property. These new systems can also be cascaded for larger domestic properties and commercial buildings. Danfoss has a network of accredited installers across the UK.

Costs Involved

Unlike installing a ground system, installation of an air source heat pump does not require any ground works, i.e. pipe laying, which significantly reduces the cost of installation. This is one of the main advantages of the air source system. Costs vary significantly depending on the size of heat pump installed. For domestic use, Danfoss prices can range from between £5,000 and £10,000. Commercial systems start at just under £10,000. Much smaller, cheaper systems are available but with Danfoss you can be sure you are getting the best available.

You may be eligible for the Renewable Heat Premium Payment, which could award you up to £1300 towards your air source heat pump installation. Support is also available through the RHI Premium Payment initiative, whereby in return for the payment, customers will be required to provide feedback on how the equipment works. RHI tariffs will become available summer 2014.

In order to be eligible for the RHI Premium Payment, you would need to be considered as part of a fair range of properties spread across all regions. You will also need to have a well insulated home and hold a current Energy Performance Certificate. Additionally, you will need to agree to allow the performance of the system to be monitored. The focus will be on properties where heating fuels are more expensive and have a higher carbon content.

Other Considerations

Your property will initially need to be assessed to make sure it is suitable for the air source heat system. If you do not already have it, then you should look into having wall and cavity insulation fitted. Finally, don't forget to check if you need planning permission.
