Case Studies

Case Study - Hall Garth Hall, Darlington

Thermal Earth worked in conjunction with Calibrate Energy Limited to provide a Ground Source Heat Pump system to Hall Garth Hotel and Country Club in the North East of England. 

Having only split phase electricity available on-site, this limited the options available. MasterTherm’s Inverter technology with Zero starting current allowed us to offer 2 arrays of 10 MasterTherm AquaMaster 45 Inverters (22kW each) in Master-Slave Cascade connection totalling a 440kW Ground Source Heat Pump System providing 95% of the yearly onsite heating and hot water requirements. The new Ground Source Heat Pump system is integrated with the existing Natural Gas boilers on-site as a backup and for peak energy requirements.

The heat is distributed over a district heating system for:

  • Domestic Hot Water
  • Radiators in all the hotel rooms and public areas
  • Swimming Pool and Jacuzzi
  • Pub
  • Gym and Spa

Over 17km of ground collector pipe was laid around the perimeter of the golf course scrub land area to absorb the energy stored in the ground from radiant sunlight. This energy is then compressed by the heat pump up to 50°c for use around the hotel complex.
