What is an Air Source Heat Pump?

An air source heat pump (ASHP) is a renewable energy system that provides heating and cooling to residential and commercial buildings. It is an alternative to traditional HVAC systems that use non-renewable energy sources.

Air source heat pumps are becoming increasingly popular over traditional combustion heating systems due to their improved energy efficiency and environmental friendliness. Unlike combustion heating systems, which require fuel like natural gas or oil to generate heat, air source heat pumps use electricity to power their refrigerant-based system that extracts heat from the air.

When it comes to how a heat pump works, it essentially functions as a refrigerator in reverse. The heat pump uses two coils – an evaporator and a condenser – to transfer heat from the air outside your home into the indoor environment.

How does an Air Source Heat Pump work?

An ASHP works by extracting heat from the outside air and transferring it to your home’s heating system. The refrigerant within the ASHP system absorbs heat from the outside air and pumps it to a heat exchanger, which releases the heat into your home.

The indoor unit of an air source heat pump contains a series of components that further work to move the heat inside your home. These include a compressor, expansion valve, and several other mechanical devices. The heat extracted from the air is then transferred to your home’s heating system through pipes.

An ASHP can be used as a standalone system, or integrated into existing home heating systems. For example, it can be connected to a hot water cylinder, allowing you to use the heat pump to supplement your home’s hot water requirements.

Air source heat pumps are becoming increasingly popular for colder climates, as they can be used to provide heating in the cold winter months. Depending on the climate, an ASHP can provide up to 4 times more heat than the same amount of electricity used in a traditional heating mode.

Benefits of Air Source Heat Pumps:

Air source heat pumps are an ideal choice for cold weather climates as they deliver warmth to your home. As the heat pump extracts warm air from outside, it is then distributed inside through your heating system and delivers enough heat to keep you comfortably warm during the coldest winter months.

One of the advantages of air source heat pumps is that they were able to stored heat, making them more efficient than traditional boilers. This means that when the outside temperature drops, the heat pump will still be able to provide warmth. Additionally, many countries offer various financial incentives for upgrading your heating system with a heat pump, including a boiler upgrade scheme in the UK. Other renewable energy sources, such as solar panels, can also be integrated into an ASHP system to further increase efficiency and cost savings. Solar panels can help reduce the amount of electricity needed to run an air source heat pump, allowing you to make further savings on your energy bills.

One of the key benefits of an air source heat pump is its low maintenance. Unlike combustion heating systems, there are no fuel tanks to be filled or replaced and the system itself requires little upkeep. This can save time and money in the long run, as well as the hassle of having to constantly monitor the system’s operation.

Energy Efficiency:

An ASHP is more energy-efficient than traditional HVAC systems, which can save you money on your energy bills. They are designed to operate at lower temperatures, which means that they require less energy to heat your home.
