The Benefits of an Air Source Heat Pump

Air source heat pumps are efficient in cold climates and can save homeowners money by providing heat for their heating, hot water and cooling systems. This is because they consume less electricity than other home heating systems.

They are also eligible for a PS5,000 grant under the Boiler Upgrade Scheme in England and Wales.


If you are looking for a low cost alternative to gas boilers, an air source heat pump (ASHP) could be the perfect solution. However, it is important to understand that this system will still require a significant investment upfront.

ASHPs are highly efficient at heating your home and can be used for both space and hot water heating. This is because they extract heat from the outside air, even at lower temperatures. This efficiency is measured by a coefficient of performance, or COP. The higher the COP, the more energy efficient it is.

When used in conjunction with underfloor heating, an ASHP can offer greater air source heat pump savings than traditional radiator systems. However, a well-insulated property is essential to ensure the system works as efficiently as possible.

The ASHP also requires regular maintenance, including inspections and cleaning of filters. However, the energy savings and reduced CO2 emissions will make this a worthwhile investment in the long run.

Energy Efficiency

The energy efficiency of an air source heat pump is determined by its ability to capture and store thermal energy. When temperatures drop, the heating system is less efficient because it loses some of its ability to absorb energy. However, new technology has made ASHPs more effective in cold climates. This makes them a viable option for homeowners who currently use gas or oil as their primary source of heating.

They are also more energy efficient than traditional gas boilers because they avoid fossil fuel combustion, and instead use a refrigerant cycle to move heat. As such, they emit significantly lower levels of CO2 than traditional systems.

A heat pump’s energy efficiency is indicated by its COP (coefficient of performance). The higher the COP, the more efficient it is. However, it’s important to note that this metric only indicates how well it performs during steady-state cooling operation. Other efficiencies, such as seasonal energy efficiency ratios (SEER), are better indicators of performance over an entire season.

Combined with insulation and draught-proofing, an ASHP can be a cost-effective way to heat your home. In fact, a typical homeowner could reduce their CO2 emissions by up to 44% per year with an ASHP, according to calculations from the Energy Saving Trust.


Noise pollution refers to unwanted sound that causes discomfort, disrupts hearing and/or damages health. It can result in sleep loss, stress, high blood pressure and heart rate, and it reduces productivity and quality of life. Noise can come from all sorts of sources, including machinery, amplified music, traffic and construction activity.

The level of noise produced by different sources varies widely, and acoustic pressures are measured on a logarithmic scale called decibels. Human ears are sensitive to sounds ranging from the whining of a mosquito’s wings to the racket of a jackhammer.

Natural sounds can reach up to 140 decibels, such as thunderstorms, avalanches, earthquakes, flowing water bodies, and animal sounds. Noise from man-made activities, including road and car park construction, building and household maintenance, industrial activity, household appliances and musical instruments can reach up to 100 decibels.

Heat pumps can be noisy when in operation, but they are not as loud as a refrigerator. Modern devices offer schedules for silent mode operation, which can be paused at night without affecting temperature control. In well insulated houses, operation can be paused for up to several hours without significant efficiency loss. Noise can also be reduced by acoustic enclosures, which reduce the amount of sound energy that is disseminated into the surrounding environment.


Air source heat pumps are much easier to maintain than traditional boilers, but they still require regular care. It is recommended that you get your heat pump serviced once a year to ensure it is working as efficiently as possible.

Generally, heat pumps have few moving parts and can operate for 20-30 years without needing replacement parts. They are able to produce hot water for your property as well, which can help reduce the amount of gas you use. They can also save you money on your energy bills as they are a green alternative to fossil fuels.

Annual preventative maintenance keeps your heat pump running smoothly all year round. air source heat pump It minimises the risk of unexpected breakdowns and results in greater cost-savings.

The most important part of maintaining your heat pump is ensuring it is clean. A build-up of dirt on the evaporator coils can block airflow and cause your system to work harder than it should, resulting in higher energy bills.

The cost of repairs and maintenance for heat pumps depends on a variety of factors, including age and type of unit. Small systems that heat and cool one room tend to be cheaper than larger units that condition the whole home. Additionally, access to the unit influences repair hourly costs as some components may be difficult or impossible to reach.
