Ground Source Heat Pumps

Heat pumps are riding an increasing wave of popularity brought on by their high efficiency and low running costs. Compared to a gas boiler that can be over 90% efficient, heat pumps can achieve 400% meaning a huge reduction in running costs. This means that for every £1 spent, you’ll receive £4’s worth of heating.


Unlike fossil fuel boilers, ground source heat pumps can generate hot water and heating 24/7 by compensating for changing weather conditions – helping to keep your home at a constant temperature all year.


Additionally, ground source heat pumps require very little maintenance which makes them perfect for many different environments. The quality and consistency of Nibe products is the reason we’ve been installing their heat pumps around Yorkshire since 2003!

Life Span 25+ Years
RHI Eligibility Yes – Up to £1,348/year for 7 years. Our engineers will be able to give you a more accurate quote
Efficiency Can exceed 400% meaning that 1kw of electricity would produce 4kw of heat
Emissions None on-site
Maintenance Yearly service – can also be monitored remotely

The Science Behind a Ground Source Heat Pump

As the sun shines on the earth, it raises the temperature of the outermost layer. By laying pipework in a series of trenches (called ground loops) a metre below the surface level, cold liquid with a very low boiling point can be circulated to absorb the low-level heat from the surrounding soil. For buildings where outdoors space is limited, ground loops aren’t feasible, so a borehole can be used instead. These operate in the same way, however it absorbs the heat from a series of pipes ranging from 90 to 160 metres deep. The pipes then transport the warmed fluid back to the main pump inside your home.


Note: GSHP’s are not feasible for all properties if there is insufficient garden space / access. Our qualified engineers will be able to guide you on the best options for your home.


This heated liquid isn’t ready to be circulated through your house just yet, it’s still less than 10 degrees but this is sufficient to turn a super cold refrigerant into gas. Within the compressor of your heat pump, this gas is converted back into a liquid which raises the temperature further, this heat is then transferred to water through a heat exchanger – following this, the newly heated water will circulate throughout your home.

Heat Pump Experience

We take great pride from only using products that we have high confidence in. All of our heat pumps are supplied by Nibe – a Swedish company that has been manufacturing heat pumps for over 50 years. Recognised as one of Europe’s largest heat pump manufacturers, their knowledge and expertise in this specialised market are second to none.

The design engineer from Warmaway will provide a radiator schedule, which will show the heat required, what heat you have got, and what if any changes are needed. We can only give the correct advice following a site survey and a heat loss calculation. This service is provided entirely free of charge, and we provide all the necessary facts and figures.
