Biomass Heating Solar Heat Pumps

Air Source Heat Pumps

Air Source Heat Pump technology is a remarkable feat in engineering. By taking colder external air from the outside environment, the unit heats refrigerant gases before harnessing the heat through a heat exchanger to provide heating and hot water to the property.

The Benefits:

  • Heat pumps can run at an efficiency of up to 400%, if designed accurately. An electrical supply is required but due to its efficiency, for every 1kW of electricity supplied the heat pump will provide 4kW of thermal energy.
  • Fully automated and unlike a biomass boiler, do not require cleaning.
  • Due to the high efficiency rating heat pumps are a cheaper alternative to gas and oil, even if the property is gas grid connected.

The Options:

Heat Pumps provide heating from 5-12kW. They can be used both domestically and commercially and are available in two main forms:

  • A Mono Bloc - the heat pump is entirely installed externally.
  • Bi Bloc - the heat pump is installed with an external and internal unit.

Both are equally efficient and the choice will be determined by customer needs and requirements.

Unlike conventional or biomass boilers, air source heat pump systems typically operate at lower flow temperatures (35-60°C) so sizing the heating system is essential to maximise the greater efficiency from the heat pump.

Heat pumps are better suited to new build homes and renovations as the building standards are higher. New builds have less ventilation losses and heat loads are lower as rooms are more efficiently insulated.

Installing Heat pumps into new build homes also means that it is easier to install heating systems such as in-screed under floor heating, which is more efficient than overlay and provides greater thermal conductivity for heating.

High temperature models available that cater for retro-fits projects.

How much could you earn?

Air Source Heat Pumps are eligible for the Domestic Renewable Heat Incentive (RHI) but at present they are not eligible for the Commercial RHI scheme.

Only applicable for Microgeneration Certification Scheme (MCS) approved heat pumps providing that the building has a Green Deal Assessment (GDA).

Take a look at our RHI Calculator to find out exactly how much you could earn from the Renewable Heat Incentive.
