The Ultimate Guide to Air Source Heat Pumps:

Make informed choices by answering all your questions.

An air source heat pump is a heating and cooling system for the air which manages the energy transfer from the outside air to into a building for heating purposes in winter. Regularly, home heating systems are usually dependent either on fuel combustions or else electrically powered systems for producing heat. Air source heat pumps, instead, carry heat from one place to another.

This is performed by a refrigeration cycle comprising a condenser and compressor to suck heat from a particular location and deliver it to another location. The residence's air source heat pump will pull air into its system from the external environment, which it will then send into the house with the help of either hot-water radiators, underfloor heating circuits, or hot air outlets.

In essence air source heat pumps function almost like normal gas boilers. Feel comfortable in any summer warmth with this toasty winter. Moreover, they can supply even more hot water at up to 80˚ C. Moreover, their operations are eco-friendly since they do not require the use of fossil fuel and therefore create no carbon emissions.

How do air source heat pump’s function?

Humility forbids the image is a fridge that can generate heat instead of cool using boiling water. The air outside is directed through coils through a refrigerant. This cold liquid becomes medicine ate as it is converted to a liquid through the air passing across the coils.

From thereon, it becomes much easier for the gas as it is still curling quietly, to quickly escape past the compressor, then increasing in temp and pressure. This is perhaps like filling the tires with air as the hose gets very hot because the heat from the compressed hot gases piles through the pump?

At the heat exchanger, the hot gases are engulfed in moisture or cool air. The heat of the gases is absorbed into the water or air and gets distributed little by little throughout the interior to warm the place. Everything goes back to square one, the refrigerant reformed, condensation becoming the initiator until the next round of a cycle commences, as the house gets warmer.

What constitutes the different varieties of air source heat pumps?

The categorization points to be collected in air to water and its air to heat. Air to heats is similar in construction to the reverse operation of the refrigerator as aforementioned. Air to water differs slightly from this procedure and is used to draw heat from the external air and deliver it to the wet central heating system. Underfloor heating or large radiators and designer radiators must compensate for the lower heat output, as the heat produced by heat pumps is significantly lower than that by a conventional boiler.

For potential buyers, the appeal of air to water heat pumps is its eligibility for the Renewable Heat Incentive offered by the government. It can potentially relieve the expense of carrying additional heating components.

In essence, this works to provide funds that cover operational expenditure to facilitate the application of renewable space heating systems within households.

Therefore, for the purpose of installing these systems within your property, air to water heat pumps retain their popularity in new builds. They won't provide the slightest disruption to the charm of your home, and there will be no expensive implications to be derived from the situation should you form an alliance with your designer in designing one in from the ground up.

Even after hiring the most professional heating contractor, the construction of an underfloor heating system can be considered rather frustrating, invasive, and expensive.

Is electricity necessary for the operation of air source heat pumps?

Electricity is crucial for air source heat pumps to work properly. However, they generate much more heat than the amount of energy they consume, making them a highly efficient alternative to traditional electric heating methods.

The efficiency level offered varies based on the specific make and model selected. For further details, take a look at our blog post covering The Ins and Outs of Modern Electric Heating.

When assessing the efficiency of an air source heat pump, one typically looks at its SCOP, or Seasonal Coefficient of Performance. This measures how effectively it produces heat in relation to its electricity consumption.

Typically, the display will feature a sole numerical figure denoting the quantity of heat energy produced in kilowatts per 1kW of electricity consumed.

For example, in the case of an air source heat pump with a SCOP of 3.2, each 1 kW of electricity used will result in a 3.2kW heat output.

Could you clarify the difference between air source heat pumps and ground source heat pumps?

One can easily spot the main difference between air source heat pumps and ground source heat pumps, much like a sore thumb that has been struck with a hammer while assembling our radiator covers. As one would expect, this is how they generate their warmth. Air source heat pumps, as their name suggests, extract heat from the air, while ground source models, similar to Paul Weller, tap into natural heat sources underground.

As previously discussed, the SCOP measurement method shows that ground source heat pumps tend to have a higher efficiency level than air source heat pumps. Specifically, while air source heat pumps typically have a SCOP rating of 3.4, ground source heat pumps typically fall within the 4.2 range.

Yes, all air source heat pumps require electricity for operation. However, the heat produced by their operation is significantly higher compared to the electrical energy they consume. So, if one considers this factor only, then they will be quite a bit more energy efficient than the usual methods of electric home heating. The extent of the energy efficiency depends on the particular make and model that you decide to purchase. For additional details about this, refer to our post The Ins and Outs of Modern Electric Heating.

The efficiency of air source heat pumps is frequently referred to by the SCOP value, which stands for Seasonal Coefficient of Performance. This is basically indicating the heat energy delivered in relation to the electricity consumed. Generally, that will be represented by a single numeral reflecting the amount of heat energy in kilowatts produced for each kW of electricity consumed. To illustrate, an air source heat pump with a SCOP of 3.2 will convert every 1 kW of electricity drawn into 3.2kW of heat output.

What is the price range for air source heat pumps?

Pricing will most certainly be the major factor for decision making among the possible buyers of air source heat pumps, since it represents a significant investment. Generally speaking, a decent quality air source heat pump can reach a price tag of about £7,000. But taking into account the installation cost on top of that, you should be ready to spend around £10,500 in total.

Moreover, it is recommended to check what might be the RHI payments to you as soon as the system is up and running. On top of that, don’t forget to compare the cost of this heating system with other renewable energy sources.

Furthermore, it is worth mentioning that the government has started in April 2022 and intends to provide UK and Welsh homeowners with a £5,000 subsidy to switch from gas boilers to air source heat pumps (more information to follow).

The price of fully installed ground source heat pumps can vary from £14,000 to £20,000 depending on the power. In contrast, biomass boilers start at around £15,000 and can have the same maximum price as ground source heat pumps. However, gas combi boilers, the most popular heating systems, can be bought at a much lower price of £1,500 to £3,500 and are thus the cheapest option upfront. Remember, though, that their running costs will accumulate over the years. If lost, one can still search and find out that air source heat pumps generally incur an annual operating expense of £750 as opposed to a conventional gas combi boiler which costs £900-£1,000.

Taking into consideration the amount you will receive from the government’s Renewable Heating Incentive program, the ability of an air source heat pump to gradually cause your heating bills to be lower becomes even more attractive.

Are necessary conditions for the broad acceptance of this renewable energy technology.

However, besides the Renewable Heat Incentive payments already mentioned, the recent proposals introduced in October 2021 indicate a potential government grant that would encourage homeowners to install air source heat pumps. Starting from April 2022, property owners in England and Wales will be able to receive subsidies of £7,500 as support for replacing their old gas boilers with modern heat pumps that are less harmful to the environment, and this will continue into the future. The transition is expected to be a major part of the £3.9bn government scheme aimed at cutting carbon emissions in the heating of residential and commercial buildings.

 The whole idea is to by 2035 get rid of all gas boilers and therefore indirectly lead to the sale of air source heat pumps which would be the only heating option for sale. One of the reasons is to improve the energy efficiency of both places. Although it has been argued that the proposal is not very ambitious and thus stifles the opportunity for the public to invest in more advanced heating systems, the whole situation still becomes a very positive one for the public intending to switch over to an air source heat pump system. Meanwhile, the experts do believe that it will be difficult for the current proposal to meet its target of 600,000 air source heat pump installations in the UK by 2028, nonetheless it is sure to push the market of households and businesses looking towards the low-carbon heat pump and away from gas ones.

The positives and negatives of using air source heat pumps.

It’s possible by now you have figured out the major pros and cons of air source heat pumps already, but we still have some points to consider, and a short list of the most important pros and cons is always handy.

Here are the main pros and cons associated with heat pumps made from air.

Some of the advantages are: good effects, good results, and good characteristics.

Simple installation – Air source heat pumps can be installed much more simply than any other natural heating system. This not only makes the installation more budget-friendly but also makes it the easiest way to cut down on your carbon footprint and energy cost through saving.

Earth friendly – It’s an air source heat pump that has less impact on the environment in comparison to the conventional gas boiler. That is, your home heating will release CO2 emissions that are way lower, thus the atmosphere of the planet will be improved.

Low running cost – The moment you decide to go for an air source pump, you become a participant in the RHI payments that the government has started. Hence, you can look forward to a good return on your investment in the long run.

The government scheme gives you access to incentives through Renewable Heating Incentive for using air source heat pumps, plus they are cheaper to run when compared with gas boilers. This means you reduce the cost of energy consumption while getting the RHI benefits as well.

On the flip side there are some negatives that should be weighed up.

The first factor that comes into the mind of people who consider air source heat pumps is the initial cost. This concern is very understandable as it is a key issue. They are not the cheapest renewable heating options but they are the most affordable to install and buy. Nevertheless, still considerable investment is required for purchasing and installing air source heat pumps which can even be higher than the costs of installing traditional gas boilers whose use is still widespread.

Potential heat output – when it is about heat output, there is a need to say that air source heat pumps may not always be able to provide the necessary heat to fully warm up a house. This could lead to the installation of more or larger radiators for getting enough heat or in some cases, the heating system may even mention an underfloor heating system to be able to function at its best. Normally this kind of information can be found in the product manual.

Sound – The air source pump condensers may produce a lot of noise along with cold air. If you are living close to the outdoor unit, this sound may be a constant source of annoyance for you.

Electric powered – Air source heat pumps need electric power to operate properly and hence they cannot be termed completely carbon free. Still, if you provide your house with electricity from another renewable source like a wind turbine or solar panels, then the use of air source heat pumps can be termed carbon-neutral.

What about an air source heat pump that is cheaper?

The primary purchase cost is usually regarded as a major hurdle, and this is exactly the reason air source heat pumps are not very common in the market. Surely, a heat pump will eventually pay for itself and become cheaper than a gas boiler. However, the initial outlay may still be too much for some, making it not an option at that time.

Are there any cheap similar devices available on the market?

I am sorry, but I have to say the air source heat pump is not only the most economical but also the most eco-friendly way to heat your home. If the initial cost is still considered high, the most likely substitute will be a modern, energy efficient gas boiler. Though these may not be available at prices that are hugely low, they are noticeably more budget-friendly compared to air source heat pumps and range between £1,500 and £3,500. Besides, investing in modern models will not be in vain as they are more energy-efficient than old gas boilers and will thus save you money on heating in the long run.
