      Why install an air source heat pump?

      ASHPs are a highly efficient way of producing heat for your home and a great alternative to traditional gas boilers. Drawing heat from the outside air which is then compressed to create heat, they offer a greener and more economical way to heat the home.

      There are plenty of advantages to installing ASHPs including:

      What grants are available for air source heat pumps?

      A heat pump is a much greener way of heating your home, so the UK government favours those who are willing to install them to help the government reach their legally binding target of reaching Net Zero carbon emissions by 2050. 

      The most relevant grant for many homeowners is the Boiler Upgrade Scheme that offers homeowners who are upgrading their old boiler to an air source heat pump up to £7,500 towards the cost of the heat pump and its installation. So long as you own the home you’re applying for, and are replacing a fossil fuel heating system, then you’ll likely qualify for £7,500 in support.

          How Air Source Heat Pumps Work

          1. Collecting Air 

          Air source heat pumps (ASHPs) get their name from the fact that they’re designed to pump air outside your home. They then draw in the heat from the outside air to heat up a refrigerant liquid. 

          2. Heating Refrigerant 

          To heat the refrigerant liquid, the warm air is compressed to increase its temperature, making it hotter and warming the refrigerant liquid until it becomes a warm gas. 

          3. Warm Home 

          This warm gas can then be used to transfer its heat to water via a heat exchanger which can then be used for zone heating via radiators or underfloor heating and for hot water in the home by warming a hot water tank for later use.

          4. Cycle Restarts

          As soon as the heat has been extracted from the gas by warming water in the system, the refrigerant begins to cool again until it becomes liquid once more, allowing the whole process to be reset and then start all over again.

          How Efficient Are Air Source Heat Pumps?

          Perhaps the real draw of ASHPs is that they’re incredibly effective. All of them are over 300% efficient, with some reaching dizzying heights of 500%+ efficiency.

          What that means is that for every 1kW of electricity used to power the heat pump, all heat pumps will be capable of producing 3kW of heat for your home, and the very best will produce 5kW+ of heat for your home.

          This efficiency means that ASHPs essentially pay for themselves and will help you save big on energy bills. So switching to a new, renewable heating system with Effective Home just makes sense.

              Air Source Heat Pumps - FAQs

              Installing ASHPs with Effective Home is a simple process. You contact us with a few basic details about your property for an instant quote. We then conduct a full, free survey to ensure your home is suitable for ASHPs (not all of them are, but we’ll cover that in our ‘Are all homes suitable for air source heat pumps?’ FAQ below).

              If it’s determined that your home is suitable for an ASHP installation, then we’ll work out a date that’s suitable for you and help you decide on some of the finer details of the installation (such as which ASHP you would like, etc). 

              On the day, we’ll send out a member of our installation team, who will take care of everything, including connecting your new ASHP to your existing heating system and removing anything that’s no longer required. 

              From initial enquiry to job completion, it could take less than 2 weeks (your home’s suitability and our team’s availability allowing). 

              If you’ve been doing your research, then you might have come across ground source heat pumps, and you’re probably wondering what the difference between the two heat pumps are, and which one is better suited to your home. 

              Ground source heat pumps work in exactly the same way as ASHPs. They compress heat to make it warmer which then turns a refrigerant liquid into a hot gas which can heat water for use in your showers, baths, radiators, and underfloor heating as appropriate. The heat exchanger, the pump itself, and all parts are basically still present. The only difference is where the pump gets its heat from.

              As the name suggests, ground source heat pumps take the heat required for the process to work from the ground. In this system, buried underground coils are put beneath the ground in your garden to extract heat from underground (which fluctuates very little in terms of temperature as it’s protected from the elements above). 

              Ground source heat pumps are an excellent option in colder climates for this reason, but they are also far more fiddly to install and often require certain conditions to be met, which make them more restrictive than air source heat pumps. 

              If possible, ASHPs are usually the preferred option for homes in the UK. 

              When you work with Effective Home, we’ll be able to install your heat pump in just a few days. This does not include the time it takes to complete the full, free survey to ensure your house is suitable for an ASHP.

              From the moment we arrive on site to complete the installation, we’ll usually be finished in a few days, causing much less disruption to your home life than if we were installing ground source heat pumps, for example, which take much longer to install. 

              ASHPs are easy to integrate into existing properties. During our free survey, we’ll be able to give you a much more accurate timescale of how long your individual installation is likely to take. 

              As with any product or service in the world, there are obvious disadvantages that need to be considered before deciding if an air source heat pump is right for you. These include things such as:

              • Higher upfront costs than traditional boilers (although with grant support the final cost is much less than it has been in previous years)
              • You may notice an increase in your electricity bills 
              • If there is a power outage, then your ASHP may be affected


              It’s worth considering if these disadvantages are greater than the advantages that ASHPs offer you.  

              Absolutely, although it’s a common myth that air source heat pumps are unable to work effectively in winter, so we understand why it’s a frequently asked question. 

              It may seem counterintuitive at first, that a heat pump that’s drawing heat from the air is able to do so in winter when it’s cold outside, but it can. Although it feels cold to us and it’s hard to imagine that there’s any heat at all in the air for your heat pump to extract and compress for heating your home and water, there is. 

              ASHPs can work in -15 degree Celsius conditions, which we rarely experience in the UK. That means our usual winters are fine for ASHPs and they’ll still continue working effectively, even when we think it’s too cold outside for them to do so. 

              No, as we alluded to earlier, not all homes are suitable for air source heat pumps. Old, draughty properties are not ideal for ASHPs because this heating system doesn’t warm a home quite as effectively as gas boilers do in terms of reaching high temperatures and keeping them there. 

              Instead, an ASHP relies heavily on your home being well insulated to keep hold of the heat it does produce. A poorly insulated property won’t be able to keep the heat in, making your home feel colder and more uncomfortable.

              You’ll also struggle to install an air source heat pump if you don’t have a lot of outdoor space. Your air source heat pump will need to be housed on an external wall, and as a general rule it takes up the space of about two standard washing machines side by side. 

              Whilst this is suitable for many properties, not all UK homes have a lot of outdoor space, and some homeowners prefer to keep what little garden space they do have for themselves, rather than sacrificing space to a heat pump.

              If you’re unsure if your property is suitable, contact us today. We offer a completely free survey to all of our customers, where one of our air source heat pump experts will be able to assess your property for its suitability. 

              And if we determine that your property isn’t suitable, for whatever reason, including if we think your home will be less comfortable to live in after an ASHP installation, then we will say so. We NEVER advise our customers to switch to an ASHP if it isn’t appropriate for them or their property.

              Most ASHPs will have a lifespan of around 20 years, although some more modern models with improved technology could last up to 25 years before needing to be replaced. To help you compare that to a standard heating system in the UK, gas boilers only have an average lifespan of around 15 years, so ASHPs do have more longevity.

              Most ASHP manufacturers also release their models with a warranty of 5 years, meaning if anything goes wrong in those first 5 years, you’re covered. 

              Air source heat pumps are considered permitted development, meaning no planning permission is required, so long as certain conditions are met. These conditions are:

              • That the size of the air source heat pump does not exceed 0.6 cubic metres.
              • The installation must be the first of its kind (with no other air source heat pumps on site) and the property must also not have a wind turbine on site. If there is already an air source heat pump OR wind turbine on site, then planning permission will need to be sought. 
              • The entire installation must take place AT LEAST one metre away from the property boundary.
              • The air source heat pump must not be installed on a pitched roof. A flat roof is permitted development provided the heat pump is at least one metre away from the edge of the roof.
              • It is not considered permitted development if the property is a listed building or within a site designated as a scheduled monument.
              • If in a conservation area or world heritage site, the air source heat pump must be installed on a wall or roof away from highways to protect the integrity and look of the area.
              • If not in a conservation area or world heritage site, the air source heat pump must not be installed above ground level on a wall that fronts a highway.


              Provided these conditions are met (which is usually the case for most UK homes), no planning permission will be required. If you’re unsure about your property, we’ll be able to advise further during our free survey.

              Energy Saving Trust updates their guidance on this regularly, but based on fuel prices as of October 2023, you can expect to save between £115 and £1100 per year in energy bills by switching to an air source heat pump depending on the heating system you’re switching from.

              If switching from an A rated gas boiler, then you may find your energy bills increase by around £35 per year, because of the electricity it takes to power your ASHP. 

              In all other cases, you’ll be making a saving. 

              No matter which heating system you’re switching from, you’ll save between 1600 and 8000 kg of CO2 each year according to Energy Saving Trust. That’s a significant amount of CO2 being prevented from entering the atmosphere each year by switching to an air source heat pump.

              If going green is important to your household, then contact Effective Home today and we’ll help you make the switch.
