Ground source heat pump : Open loop GeoReport

Ground source heat pump : Open loop GeoReport

This report is designed for users proposing to install ground source heating or cooling using an open loop borehole system.

Open loop systems utilise groundwater as a direct energy source.

They use an abstraction borehole to take groundwater as the fluid for the heat pump, pass it through a heat exchanger and then either re-inject it back to the aquifer using a re-injection borehole or sometimes discharge to a nearby watercourse or sewer.

For closed loop systems see Ground source heat pump : Vertical closed loop

The modules included in the base report are the modules that we recommend. You can however select a combination of available modules and create a fully customised report by selecting Site Investigation Borehole.

Our Ground Source Heat Pump reports go to a depth of 150 m as standard. If you require a greater depth than this (up to a maximum of 300 m) this may be possible for an additional charge but please contact us via with details of the location and the report required before placing an order. We will review the data available for the site and see if it is possible to meet your requirements and provide you with a quote.

If you are unsure whether you need a closed or open loop report then please select our Site Investigation Borehole report and select one of the "Groundwater abstraction" modules along with the "Temperature and Thermal properties detailed" module below. This will provide enough information for a qualified professional to look at the viability of both options. Please note in comments that you wish to have information for both a closed and open loop system.

Optional module

Engineering Geological and Drilling Considerations
This module gives a preliminary guide highlighting issues the site geology might pose for drilling and ground engineering.

Areas of complex geology

For areas where the geology is very complex, the reports take significantly longer to write and this is reflected in the price. Please see the "Report availability map" for an indication of the area, these areas are shown in purple on the "Report availability map".


Geological Map Extracts are not available in some areas of the UK. These areas are shown in yellow on the "Report availability map" below.

All prices include delivery.
