Are air source heat pumps any good?
The simple answer is yes, but only if they are made by a reputable manufacturer, installed correctly at a property which has been assessed as suited to using an ASHP as its heating solution and designed correctly for that property. Please read on for more about the pros and cons of air source heat pumps.
If you’re looking for a new way to stave off the cold this winter, you may have already explored the option of installing an air source heat pump (ASHP). As a renewable heating solution, it is powered by electricity and draws heat from the outside air.
This technology will minimise energy usage, whilst providing effective warmth all year round. An air source heat pump is good for the environment and doesn’t compromise your comfort. Your wallet will also be thankful in the long run, as against fuel costs of many other systems, household utility bills plummet significantly.
How does an air source heat pump work?
While you may have heard the term floating around, you might be uncertain as to how an air source heat pump actually works. Heat pumps take heat from a specific source – air, ground or water – and use it to power heating and hot water inside a building.
An air source heat pump can be used to regulate the temperature in your home, depending on the needs of the season. The physical structure of an air source heat pump consists of two components. A unit is installed outside your house on an external wall, which is connected to a separate component inside the house that feeds a wet heating system (air-to-water). You can also get air-to-air heat pumps which dispense warm air, but these are less common in the UK.
Environmental and financial costs
At the top of the list of benefits of using a heat pump is energy efficiency. Heat pumps are 300% to 400%+ efficient. Making use of either a ground source or air source heat pump can seriously curtail the negative effects of household heating on the environment.
Upfront air source heat pump costs are higher than a conventional heating system, but cheaper than a ground source heat pump. Usually, air source heat pumps cost between £9,000 – £15,000. Financial help is available via the BUS Scheme or the Home Energy Scotland Loan.
So, what would I be signing up for?
If an air source heat pump is looking more like the right option for you, it’s worth understanding what physical presence it will have in your property. You’ll be pleased to know that a big selling point of an air source heat pump is its modest size.
The outdoor unit measures approximately 1.5m x 1.5m for a system that will heat an average family home. This makes it ideal for many British homes, where outdoor space is at a premium. When it comes to installation, an air source heat pump is far less disruptive than installing a ground source heat pump. Whichever route you go, make sure you follow the proper channels when it comes to installation. It cannot be stressed enough – use a reputable installer that will get the job done in way that does not cause disruption further down the line.
When are air source heat pumps NOT the right option?
Whilst the benefits of air source heat pumps far outweigh the downsides, it is important to note that this solution is not perfect for every home. Utilising the right heat pump installer is vital, as they will be able to professionally assess any criteria that will makes it an incompatible heating source for your property.
If your property’s insulation is inadequate, this may not be the most effective option for you. The potential for other distribution is also a factor to consider when making your decision. Low-temperature heat may require larger radiators to provide adequate distribution. In simple terms, air source heat pumps provide constant heat at a lower temperature when compared to conventional systems.
In addition, there can be a noise factor involved with air source heat pumps, although this has improved dramatically with the latest technology with many of the manufacturers boasting the quietest. Whilst the noise is minimal from the outside unit ranging from 49dB to 60dB depending on which unit you have, ensuring that it is placed correctly and adhering to MCS020 standards is imperative.
In many cases, and especially for larger properties – ground source heat pumps are the most efficient solution. They may be a better option for you, but it depends on the building’s heat demands, your available outside space, and your budget. Speak to one of our advisors to learn whether a ground source or air source heat pump is most suitable for your needs.
Summary
Air source heat pumps can go a long way to reducing your energy spending, whilst efficiently heating your home. The Boiler Upgrade Scheme currently provides money off your install costs in Scotland the Home Energy Scotland Loan can assist with the up front capital costs and provide substantial cash-back.
However, it is vital that you do your research and get the best advice. Always make sure that an accredited installer is doing the work, and that you trust their advice and guidance. A well designed, well installed heat pump will simply work – that’s what you can count on with IMS Heat Pumps.
