Should I Choose an Air or Ground Source Heat Pump?

Those searching for renewable energy sources can often find themselves deciding between air and ground source heat pumps. Though they are quite similar in design and operation, there are some benefits of the air source heat pump that might sway you towards them over their ground counterparts. Let’s take a closer look at the two, and why you might want to select an air source heat pump.

How Do They Work?

Air and ground source heat pumps can both be used to heat the water for your home – providing hot water that can then be used in radiators or underfloor heating or from the tap. This is an efficient way to heat a property, and both sources can help homeowners to save in terms of their utility bills.

The difference between the two pumps is quite straightforward. An air source heat pump will absorb heat from the air around it. Meanwhile, a ground source heat pump takes its heat from the ground. It really is that straightforward.

A Question of Cost

One of the big factors that can determine a heat pump installation can be the cost. Here, the air source heat pump will always win. It costs around £12,000-15,000 to install an air source heat pump. A ground source heat pump costs significantly more, usually costing somewhere between £30,000 – £50,000. There are also some higher costs involved with the installation of a ground source heat pump too.

There are several incentives that apply to both air and ground source heat pumps. Home Energy Scotland offers loans and other information into the incentive and cashback schemes that a household could apply for should they choose to add a heat pump to their property. This could make installing such a solution much more cost-effective.

Ease of Installation

When it comes to installing the heat pumps, an air source heat pump is easier to install compared to its counterpart.  They do not require land to be dug up, and don’t take up too much outdoor space. In fact, it looks very similar to an air conditioning unit once installed. Since the unit is often visible on the outside of the property, you might need to acquire planning permission for its installation.

A ground source heat pump will require a lot of outdoor space, and excavations will need to take place to fit the pump. Though it can be laid vertically instead of horizontally, a better option for smaller gardens, there might be a need for more digging plus specialist equipment for installation. When considering the higher initial cost of a ground source heat pump, the project only becomes more expensive when you add in installation.

Both are fantastic options for a renewable energy source in your home. However, the ease of installation and lower costs of an air source heat pump do make it a preferable choice for many.
