About New build projects

Air source heat pumps (ASHPs) are renewable heating systems that extract heat from the ambient air and convert it into usable heat for space heating and hot water in residential and commercial buildings. Here are some key points about air source heat pumps:

1. Operation: ASHPs work by utilizing a refrigeration cycle. They absorb heat from the outdoor air, even in colder temperatures, and raise the temperature using a compressor. The heat is then released into the building's heating system or hot water supply.
2. Efficiency: ASHPs are known for their high efficiency. They can produce more energy in the form of heat than the electrical energy they consume. The coefficient of performance (COP) measures the efficiency of an ASHP, with typical values ranging from 2 to 4 (meaning 2-4 units of heat produced for every unit of electricity consumed).
3. Heating and Cooling: Air source heat pumps can provide both heating and cooling capabilities. They can reverse their operation, allowing them to act as an air conditioning unit during hot weather by removing heat from the indoor space and releasing it outdoors.
4. Benefits: ASHPs offer several benefits, including reduced energy consumption, lower greenhouse gas emissions compared to fossil fuel-based heating systems, and potential cost savings on energy bills. They are also considered a renewable energy solution since they extract heat from the air, which is a freely available resource.
5. Installation: ASHP installations typically involve positioning an outdoor unit that contains the compressor and heat exchanger. The system is connected to the indoor heating distribution system, which may include radiators, underfloor heating, or a forced-air system.
6. Compatibility and Integration: ASHPs can be integrated with existing heating systems or used as standalone heating systems. They can work alongside conventional boilers or be the primary heating source, depending on the specific requirements and configuration of the building.
7. Considerations: Factors to consider when installing an ASHP include the suitability of the building's insulation and heat distribution system, the climate conditions in the region, noise levels of the outdoor unit, and the available space for installation.

It is important to consult with a qualified heating engineer or renewable energy specialist to assess the feasibility and suitability of installing an air source heat pump based on the specific requirements and characteristics of the building.
