Heat pumps are heating and cooling systems that transfer heat from one place to another using a compressor and a circulating structure of liquid or gas refrigerant.
Heat Pumps
They extract heat from the outside air or ground to heat a space and can reverse the process to cool space in warmer months.
This makes them an efficient and versatile option for both heating and cooling needs in various climates.
Air Source Heat Pumps (ASHPs)
Air source heat pumps extract warmth from outside air and bring it indoors, functioning well even in sub-zero temperatures.
Using a refrigerant system, they absorb and amplify outdoor heat, then distribute it inside via radiators or vents. These pumps are highly energy-efficient, producing three times more heat per energy unit used.
When combined with renewable energy sources like solar panels, they offer enhanced environmental benefits, providing clean heating and reducing carbon footprint for sustainable living.
Ground Source Heat Pumps (ASHPs)
Ground source heat pumps (GSHPs) extract heat from the ground, using a network of underground pipes filled with a water and antifreeze mix.
They are notably efficient, achieving about 400% efficiency. However, this efficiency comes with higher purchase and installation costs.
GSHPs require a significant land area for the pipe network, often up to 1200 square meters, roughly three times the heated property’s footprint.
These factors, especially the land requirement and installation expense, make GSHPs less practical for many homeowners compared to the more space-efficient and cost-effective ASHPs
