GSHP CASE STUDIES

 
 
  • Roffey Park

    We worked with Baystar on this project and were responsible for designing and installing a retrofit 120kW ground source heat pump with back up oil boiler. The heat pump was designed to deliver 80% of the load.

    A ground source heat pump was installed for the main building utilising the lake on-site as the heat source. Baystar carried out a full feasibility study incorporating additional buildings but the cost benefits did not stack up and carbon savings was a key consideration.

    The study involved assessing the annual load profile and estimating the percentage of the heat pump. Various operating scenarios were considered to enable the size of system to be selected and an assessment made to ensure we had the required volume of water within the lake.

  • Tattleton Estate

    ​A 90 kW cascade system of heat pumps using 18 loop lake collector was installed at this working equestrian estate to provide fuel security, reduce heating costs and provide income from the Renewable Heat Incentive (RHI) scheme.

     

    Lake System Design:

    • CTC Ecopart 90kW heat pump cascade

    • Utilises estates own lake, with collector pipe fed into central manifold

    • Heats five separate buildings linked together to form a district heating scheme

    • Is eligible for the Renewable Heat Incentive (RHI)

     

    Complete Ground Source Package

     

    All 5 buildings are linked with 1000m of underground pipe. The efficiency has already exceeded expectations even when the lake has been covered in ice, with fast hot water heat up time.

    GeoScience undertook the design of the closed-loop lake collectors and the associated, source side distribution pipework to the separate heat pump locations. “Great system, completely invisible and a real talking point for guests. Fantastic hot water production and extremely low maintenance. RHI incentive makes the scheme incredibly profitable and worthwhile both environmentally and financially”

     

    Fuel cost saving; Up to 50% c. £8k (estimated electricity cost)

     

    RHI Payments;

    A project of this size would gain an average of £18,000 every year for 20 years, index linked to inflation
