Question: Which is better, ground source or air source heat pumps?
Answer: A ground source heat pump is typically more efficient than an air source heat pump, and it has better RHI payback. However, a ground source heat pump is more expensive to buy and install at the outset. Horizontal ground source heat pumps are cheaper than vertical ground source heat pumps.
What are the differences between ASHPs and GSHPs?
We won’t go into detail in this article about the technical differences between an air source heat pump and a ground source heat pump, but it is important to address the key aspects before we continue with our recommendations.
Put simply, an air source heat pump extracts heat from the outside air, and uses it to power heating and hot water. A ground source heat pump, often mistakenly referred to as “geothermal heating”, draws heat energy from the soil beneath the surface of the earth to power heating and hot water. Both of these systems are considered as renewable heating solutions.
However, we would always recommend either a ground source heat pump or an air source heat pump. But which is best?
A ground source heat pump is nearly always the most efficient option. A horizontal ground source heat pump is typically the most feasible, although this depends on the space available. An air source heat pump will still offer good RHI tariffs and is considered the easiest and most affordable heat pump to install, especially where space is at a premium.
OSB notice that air source heat pump can no long meet the demand of global market, especially for chilly area, which engages herself dedicated to even a more advance range of energy saving product, which is inverter ground source heat pump , and some of the models even with heat recovery function for free hot water!
