What are the Benefits of Using Heat Pump Technology?

Air Source heat pumps are thought to be one of the most cost effective ways to power a domestic heating system. They work by removing heat from outside air, into cooler air inside the building.
In a well insulated home they offer a cheaper alternative to traditional fuels and could reduce the carbon footprint of the homeowner by as much as 10 tonnes annually.
They don't generate carbon monoxide thanks to non-combustion based technology so they are very safe. The systems are also extremely adaptable and may be installed in new build properties or retro-fitted to existing buildings, with barely any adaption.
Most systems have an average life expectancy of 20 years, so an air source heat pump unit offers the householder an extremely cost effective and environmentally friendly way to heat their home and water.
The government also pays those who generate and use renewable energy to heat their buildings. The Renewable Heat Incentive (RHI) means most pumps are paid back in just five years, creating a Return-On-Investment (ROI) of 28%. The RHI is set to cover domestic use from summer 2014 but in the meantime the Government has offered a one off grant to help with the installation costs, this can be up to £1300.

How Does an Air Source Heat Pump Work?

An air source heat pump extracts the external heat from the atmosphere and transfers it to the interior of the property to provide heating or hot water. In the same way as a refrigerator extracts the heat from the interior of machine and expels it through the elements at the rear, the air source pump will do the reverse; drawing the heat in, boosting the temperature through compression and then emitting the warmth throughout the building.

There are two different applications for air source heat pumps. An air-to-water system circulates heat through a centralised heating system such as radiators or underfloor heating, while an air-to-air version circulates the generated heat around the house with the use of fans.

Which Air Source Heat Pump Systems are Available in the UK?

As one of the country's leading renewable energy suppliers, Spirit Solar recommend three manufacturers for energy efficient and economical air source heat pump units; Hitachi, Mitsubishi and Dimplex.

All three have received Microgeneration Scheme Certification (MSC) accreditation. Only pumps installed by MSC accredited workers will be eligible for the government's RHI scheme. All three performed excellently when tested in low temperatures (to 0 degrees centigrade) and all manufacturers provide a comprehensive range of heating accessories which can be used to enhance the system's performance and efficiency.

Dimplex Air Eau

Dimplex has been in the renewable energy technology market for more than 30 years and is a well known and trusted name among both UK consumers and the international market. Their range of air source heat pump systems are all provided with a full three year warranty.

The Air Eau range is available in four different sizes; 6kW, 9kW, 12kW and 16kW, providing a suitable option for any size of property. The compact design makes installation swift and easy and very little preparation is required to make the system fully operational.

This model is fitted with a night mode feature which means it is almost silent it has an integrated automatic defrost function for when it gets very cold. It also comes with additional immersion heater facilities which can be operated as a back up to the system should temperatures fall significantly and the household need to boost the hot water supply.

Mitsubishi Ecodan

Manufactured in Scotland, the Mitsubishi Ecodan delivers a highly efficient and technically advanced air source pump system. It is available in three sizes; 5kW, 9kW and 14kW and can deliver Co2 reductions between 30 and 50%.

Due to Mitsubishi's innovative technology, the Ecodan range is able to outperform a conventional boiler, generating much more heat. The Ecodan generates 3.3kW for a consumption level of 1kW. It will also perform in external temperatures as low as -20 degrees centigrade and can provide constant hot water up to 60 degrees centigrade.

Hitachi Yukati M

The Yukati M is a compact, external air source heat pump unit which provides an energy efficient delivery of heating and hot water to the domestic property. It reduces CO2 emissions by 50% and can save you up to 60% on your bills compared to running a traditional boiler. It generates 5kW to 1kW input.

As the unit is designed for external installation, it has a wireless control for touch button operation and a weather compensation control feature for inclement conditions. The Yukati is widely used in Germany and Scandinavia, where extremes of temperature are commonplace. A five year full warranty is offered with each installation.
