An air source heatpump (ASHP) is a reversible heatpump that uses the same vapor-compression refrigeration method and also the same outside heat exchanger with a follower as an ac unit to use the outdoors air as a warmth source when in house heating mode or as a warmth sink when in cooling mode.

Air to air source heat pump
Heat is transferred from the outside air to the air within your home via air-to-air heat pumps, boosting the temperature in each room. Air-to-air heat pumps are frequently mistaken for air conditioners. While most people think of air conditioning as a technique to cool down buildings, it may also be used to heat them.
What is a water source heat pump?
A water source heatpump works similarly to an air source heatpump, only it extracts and dissipates heat through water rather than air. They do this by cycling water through a pipeline system installed at the water’s edge.
What is a ducted air source heat pump?
A ducted air source heat pump is a large system that uses ductwork in the ceiling or floor to cool and/or heat multiple areas. Diffusers are used to spread the air, as shown below.
What is a ductless air source heat pump?
A ductless heat pump is an outside equipment that transfers heat from a source to a heating storage system. This system then distributes heat throughout the home, whether to hot water pipes or a central heating system, depending on how the heat was planned to be distributed.
Unit & Installtion & Running Cost
The cost of purchasing and installing an air source heat pump ranges from £3,000 to £18,000 ($4000 to $24000). Air-to-water is the more expensive option, with supply and installation costs averaging £13,000 ($17000). For delivery and installation, air-to-air costs roughly £3,100 ($4100). Although air source heat pumps are more expensive than many traditional heating systems, the environmental advantage is significant.

Air source heat pump efficiency
An Air Source Heat Pump (ASHP) typically generates 3kW of thermal energy for every 1kW of electrical power consumed, resulting in a 300 percent effective “efficiency.” More than 100 percent efficiency is thermodynamically impossible because it suggests that more energy is generated than is put in. As a result, rather than efficiency, the performance is expressed as a Coefficient of Performance (COP). A COP of 3 would be assigned to the above scenario.
How much do you save with an air source heat pump?
With typical COP values of 3.5 to 4.5 (ground source heat pumps) and 2.5 to 3.5 (air source heat pumps), it can save up to 52 percent when used alone for space heating rather than a gas boiler.
Because of their higher efficiency and lower utility costs, air source heat pumps can save money in the long run; however, they are often linked with higher upfront expenses than traditional heating and cooling systems, so you may want to look into financing possibilities.
Your savings from installing an air source heat pump will be determined by the sort of fuel you now use for heating. Here are some estimates for how much money an air source heat pump system could save a typical 2,000 square foot home in Massachusetts.

Air source heat pump noise
What Is Decibel?
An equipment that measures sound in decibels is used to measure it. The abbreviation is dB. At 0 dB, there is no audible noise; after that, every 3 dB increase doubles the sound intensity, or acoustic power. The noise level in the room is 30 decibels.
How much noise does an air source heat pump make?
Heat pumps, on the other hand, are usually quieter than fossil fuel boilers. An air source heat pump can reach 42 decibels, whereas a ground source heat pump can reach 40 to 60 decibels, depending on the manufacturer and installation.
Reduce Air source heat pump noise
- Tighten mounting bolts
- Install vibration absorbing pads
- Clean the fan blades
- Secure loose parts
- Level the heat pump
- Replace noisy parts
- Unclog drains
- Remove leaves and debris
Popular questions of air source heat pump
Do air source heat pumps use refrigerants?
Air source heat pumps work similarly to central air conditioners, but they may also supply heat to keep your home warm throughout the winter. A chemical molecule called refrigerant is used by a heat pump to accomplish both tasks.
Does air source heat pump work with radiators?
YES! Air source heat pumps work well with radiators.
Can you heat a swimming pool with an air source heat pump?
Heat is captured from the air and transferred to the water in your pool using air source heat pumps. Swimming pool air source heat pumps are an energy-efficient way to heat your pool water; for every unit of electricity used to operate them, you can get up to 5.25 units of heat.
What is the effective temperature range of an air source heat pump?
The heat pump has to work harder when the outside air temperature drops, making it less efficient. The COP continues to fall until the outside temperature reaches -4°F (-20°C). Our air source heat pump’s effective temperature range goes down to -4°F.
How cold is too cold for an air source heat pump?
The current AHRI 210/240 testing standard for air source heat pumps in the United States does not even test below 17°F. This gives little to no indication of how products perform in sub-zero temperatures, if they can even operate at all.
