Ground Source Heat Pump (GSHP) FAQs

by | Apr 9, 2021

Ground source heat pumps are a great alternative to conventional methods for heating your home, business facility or development. We’ve written previously about the various benefits of having a ground source heat pump installed, but today we wanted to look at some of the most frequently asked questions (FAQs) people come to us with when considering this heating option. Here at Borehole Solutions, we’re well-experienced in these installations so if you’re looking for answers, you’ve come to the right place!


How Do Ground Source Heat Pumps Work?

They’re actually pretty simple devices, in truth! They work by installing a loop (or series of loops) underground and then circulating a fluid through the pipe. As the fluid is pumped around, it absorbs heat from the underground and is then passed through a heat exchanger to provide the heat energy in a practical, usable form.


How Much Does It Cost To Install A Ground Source Heat Pump?

There’s no one set prize when it comes to installing a ground source heat pump; mainly, because scale and complexity tends to vary massively from project to project. Quotes tend to range, however, between £10,000 and £20,000 (another variable that affects price is whether you’re inserting a trench or borehole-based ground source heat pump system).


How Much Space Do I Need?

It depends on the type of system you have installed as you can either implement a horizontal version or a vertical borehole system. For horizontal systems, a relatively large area is required (between 500 and 700m2 is fairly standard) whereas vertical borehole systems require much less space. With a borehole being drilled using a specialist rig, these holes are relatively narrow in diameter but their depth can range from around 15m to well over 100m – it very much depends on the site in question.


Are Ground Source Heat Pumps Energy Efficient?

Yes, very! According to the UK’s Ground Source Heat Pump Association, these pumps are up to 400% efficient in terms of their overall energy usage and produce carbon dioxide emissions 70% lower than conventional gas boiler heating systems. If you’re looking to make your home greener, then ground source heat pumps are a good choice to consider!


How Much Maintenance Do Ground Source Heat Pumps Require?

Asides from being checked annually, these systems are relatively low maintenance and will last you a very long time – in fact, most ground source heat pumps can last somewhere between twenty and thirty years without breaking a sweat! It’s important that you always call in a qualified engineer or the contractor who installed your pump to carry out any checks or maintenance works required.
