Understanding air source heat pump efficiency
Air source heat pumps extract heat from the ambient air to deliver constant warmth for your home. Much like the process that keeps your fridge cool but in reverse, the heat that is drawn in by the ASHP is absorbed by a refrigerant, and a compressor heats the gas that is created. The heat produced is then transferred around your home using a compressor.
Modern ASHPs can work even in low temperatures where there is less heat in the air for them to draw upon. They are also more efficient than older systems, three to four times more efficient in some cases, and as they use a renewable energy source, you have the benefit of reducing your carbon emissions and your bills at the same time.
When combined with other energy efficient measures and quality insulation, an air source pump can lead to a constant level of comfort and heating performance for most property types.
Heating and hot water capabilities
It’s important to note that an air source heat pump needs to work with a compatible cylinder in order to meet heating and hot water needs.
The gas produced during the process of the ASHP extracting heat from the ambient air for use in your heating system is transferred to an internal heat exchanger within the hot water cylinder. The water is stored ready for use, ensuing that you have a constant and consistent supply of water, heated using a renewable source.
Choosing the right system for your home
To decide if an air source heat pump is the right solution for your home, consider your property’s specific requirements. Key elements such as insulation, size, and the number of occupants. You’ll also need to consider your typical energy and hot water usage, as this will influence the size of air source heat pump you’ll need and the hot water cylinder to go with it.
An air source heat pump is situated outside your property, either mounted on an exterior wall or positioned on a sturdy flat surface. This position is important as your ASHP will need to be accessible for maintenance checks and has an unobstructed airflow, without causing a hazard to other household members.
To ensure maximum efficiency and effectiveness of an air source heat pump, check that you have quality insulation fitted and that any gaps around windows and doors are sealed. If your property is restricted on space, you may want to consider a pre-plumbed hot water cylinder for your ASHP, as this type of cylinder doesn’t have a header tank, perfect for tight spaces, and also makes for a smoother installation process.
Air source heat pump installation
Professional installation is key to ensuring that your system operates at peak efficiency. An expert assessment will help determine the right model and configuration to meet your heating needs, providing peace of mind and long-term energy savings.
Various grants and incentives may be available to help offset installation costs. One in particular is the Boiler Upgrade Scheme, which provides cash grants towards the cost of an air source heat pump depending on eligibility.
There are some instances where additional regulations need to be followed for an air source heat pump installation. For example, if your property is a listed building or within a conservation zone, you may need to have additional permission from a local authority.
