Heat pumps absorb heat from the environment, transforming it into a fluid which is then compressed to further increase its temperature. This heat can then be transferred into a central heating system, where it can provide heat for your home and hot water.
As this Energy Saving Trust article notes there are two different types of heat pumps: air source (ASHPs) and ground source (GSHPs).
What is an air source heat pump?
ASHPs transfer heat from the air outside into water, which can be used to provide warmth for your home via underfloor heating systems and radiators. ASHPs can also heat water that is being stored in a hot water cylinder.
As heat from the air is transformed into a fluid, it is passed through a heat exchanger before arriving in the heat pump. Here the temperature is raised and transferred into water and heat.
You will need to have a place outside your property to place an ASHP, either on the ground or fitted to a wall. It is important that your heat pump has some space on either side to ensure good airflow.
What is a ground source heat pump?
GSHPs contain a thermal transfer fluid (TTF) which is composed of antifreeze and water. TTF flows around a stretch of pipework buried underneath your garden where it absorbs heat from the ground. This fluid is then passed through a heat exchanger and into the heat pump.
You need to have some outside space if you want to invest in a GSHP and aren’t averse to drilling boreholes or digging trenches. If you do have this available space, it is worth considering this type of heat pump because they can be much more efficient in colder temperatures.
Which system should I choose?
If you’re looking for air source heat pumps Cheltenham, look for teams such as gsmlimited.com/services/air-source-heat-pumps/cheltenham,with experience in supporting their customers to select the right heat pump model and system layout.
Your installers should discuss everything from available space to government grants and schemes to ensure you find the right solution for your home.
