Our engineers are capable of undertaking in-situ soil temperature and thermal conductivity measurements for the design of the horizontal Ground Source Heat Pump (GSHP) systems.
 

Benefits of GSHP systems include:

 

  • Lower your fuel bills, especially if you replace conventional electric heating

  • Lower home carbon emissions, depending on which fuel you are replacing

  • No fuel deliveries needed

  • Can heat your home as well as your water

  • Minimal maintenance required

 

Thermal Probing

FWS provide a specialist, cost effective and rapid service to provide site specific soil temperature, thermal conductivity and soil type data for use in the design of horizontal closed loop systems. Typically, to determine the evaluate the soils characteristics and determine the “bulk” soil conductivity for a 1- 2 ha site, around 10 to 20 thermal probe tests are required.

 

These tests, to determine the temperature and thermal conductivity, are undertaken at a depth of around 0.2m below the local frost line, within either augered boreholes holes or trial pits, to a depth of around 0.6m to 1.5m.

To obtain sufficient data for a 1 – 2 ha site, a thermal probing survey typically takes between 1 – 2 ha in area and takes 1 day to complete, with the factual report issued soon after.

FWS Expertise

FWS engineers have extensive experience in undertaking thermal probing surveys across the UK, with surveys in Scotland serviced from our Scottish office in East Kilbride and surveys in England, Wales and Ireland from our head office in Durham. We provide a cost-effective service and rapid response to coordinate and complete the probing survey and reporting.

FWS operates an ISO 9001:2008 Quality Management System accredited by the British Standards Institute for the provision of geological, hydrogeological and geo-environmental services, which maintains the accuracy, quality and reliability of all of our work processes.

We also have extensive experience in the design, system-integration and performance modelling of both ground- and air-source heat pump systems for heating and cooling of buildings. We are able to carry out design and feasibility studies on a wide range of options including vertical closed loop ground arrays, closed loop horizontal ground arrays, open loop systems including standing column wells, naturally-occurring water sources such as rivers and lakes, air-source options and hybridisations of all of these sourcing strategies. Our bespoke modelling methods can be used to explore seasonal energy use, design capacities and plant sizing, carbon savings and financial economics. For new-build applications and situations where thermal demand profiles are unavailable, we are able to carry out building thermal modelling in order to explore heat pump system options benchmarked against conventional heating and air conditioning approaches, the impact on local electrical infrastructures, use of thermal and battery energy storage and the evaluation of alternative system control strategies.
