Case studies: Using Ground Source Heat Pumps in Commercial and Community Buildings

April 25, 2019

case study imagesAs part of the GeoAtlantic project we have been finding out more about businesses and community groups in Argyll which are using ground source heat pumps to meet their heating and hot water needs whilst reducing their carbon footprint and earning money from the Renewable Heat Incentive.

Our case study of the Islay Hotel in Port Ellen looks at how one business is using boreholes beneath their beer garden to create a warm welcoming environment for guests and provide all the hot water they need for showers, even at peak times.

Our case study of Dunaverty Village Hall in Kintyre examine how one community group dug trenches beneath their sports field to collect heat stored in the ground to heat their post office, meeting rooms and sports hall, all whilst earning them around £80,000 over 20 years form the Non-Domestic Renewable Heat Incentive.

Whilst both buildings are new-builds, ground source heat pumps are also suitable for retrofitting into many buildings and the heat can be distributed by radiators as well as underfloor heating.

As always, as well as choosing the right system, the key is ensuring that your building is as well insulated as possible as this will give you the greatest benefit of any heating installation.

For more information on support available for community groups and businesses wanting to invest in ground source heat pumps contact Local Energy Scotland.


Funding available for local heating project

September 25, 2018

We’re seeking expressions of interest from groups or individuals who would like to receive funding towards the cost of a heating or cooling system which uses the earth’s natural energy to serve homes, community buildings or business premises.

The system will be installed as part of the GeoAtlantic project and act as a model for others who might be interested in using geothermal energy or heat pumps.  In return we can offer a range of support including a substantial contribution to the costs of designing and constructing the system and wider project support including help to identify additional funding if required.

To find out more see our Geothermal and heat pump page.

The GeoAtlantic project is co-financed by the Interreg Atlantic Area Programme through the European Regional Development Fund.

Exploring the potential of Geothermal

August 28, 2018


IET are please to be part of a European project looking at the potential of geothermal energy for communities which border the Atlantic Ocean.

Alongside partners in Scotland, England, France, Portugal and Spain, we will be investigating the options for using geothermal energy to heat and power homes and businesses on Islay, Jura and Colonsay as part of the GeoAtlantic project, as well as working with our partners to develop tools and resources which will assist those looking to use geothermal energy.  We aim to develop a geothermal resource which can be used as a pilot project and learning resource for local people and the wider GeoAtlantic community.

The project is in its early stages but we’re keen to hear from anyone on Islay, Jura or Colonsay currently using a ground source, air source or water source heat pump in their home or business, or from anyone thinking about installing one.

To let us know about your system, or for more info, contact the GeoAtlantic project Development Officer, Kirsten Gow, at or call 01496 301413.
