What Are the Advantages and Disadvantages of An Air Source Heat Pump?
In order to decide if an air source heat pump is right for you it’s worth considering the following advantages and disadvantages:
- Air source heat pumps have a high CoP making them very energy efficient.
- As a result of their high CoP, they are usually more cost effective than other home heating systems.
- Air source heat pumps have a good lifespan and require low maintenance.
- They are easier to install than ground source pumps.
- Their low or zero carbon footprint (if used with a renewable energy tariff) is very good for the environment.
- Installation costs can be offset by the UK government’s boiler upgrade scheme.
- Some homes especially flats are not suitable for air source heat pumps given the space needed for the installation.
- They will only work at temperatures of minus 15°C and lower however energy efficiency decreases the colder it is outside and in colder temperatures more electricity will be required.
- Radiators will feel warm, not hot, as air source heat pumps supply lower heat than boilers, so homes will take longer to warm.
- Your home needs to be well insulated to keep the heat in.
- Air source heat pumps can be noisy so it’s best to site your pump at a distance from your home.
What To Do Next Having Decided an Air Source Heat Pump Is Right for You?
Once you’ve decided that an air source heat pump is right for your home what’s the next step and how do you ensure that you get the most out of your new heating system?
Finding the Right Installer
When it comes to the installation, you’ll want to ensure that you find the right air source heat pump installer.
It’s important that your installer understands the technology and how to ensure your installation gives you the best return for your investment in terms of installation and running costs. In order to do that the installer needs to have a clear understanding of how low temperature heating systems work, the requirement, and workings of the required control system as well as which brand would work best for your home and what design will give the best results.
It’s also a good idea to get a quote which covers the following: what will be covered as part of the install e.g. will the price cover radiator upgrades if required, is integration with your existing system included if required, will removal and safe disposal be included if any system components need to be replaced; will the cost cover the commission of the system, will the installer carry out the whole job or do they sub contract or will other trades be required to complete the work, will the installer provide the efficiency values of the system and what payment plans are available to you and are they covered by insurance?
Understanding Your Air Source Heat Pump System
Once your system is installed it’s important to understand how it works, to ensure you are getting the best out of the system. Take the time to understand your heating controls and how to use them effectively. Refer to your system’s user manual and ensure your system is setup to give you the level of heating and hot water that best suits your needs in line with your daily routine.
The harder an air source heat pump has to work the more electricity it will use. Air source heat pumps also need longer to heat your home so set your pump to supply heat at a lower temperature over a longer period of time so that your home is warm when you need it to be while energy consumption is kept as low as possible.
When you have your heat pump system on close your windows and doors to ensure the heat generated does not escape through an open window. It’s also important to ensure you have good insulation so that heat is not lost.
Check that your external unit is not blocked by debris e.g., leaves and remove any items that may obstruct the unit including plants or snow and ice during the winter months.
Maintaining Your Air Source Heat Pump
Just as with any mechanical and electrical system its vital to maintain the system and service it on a regular basis so that any issues or faults are found and corrected as quickly as possible, and the system continues to work effectively and efficiently.
