Heat Pump System Design & Specification

The most important step in the design of a ground source heat pump installation is the accurate calculation of the building's heat loss, its related energy consumption profile and the domestic hot water requirements. This will allow accurate sizing of the heat pump system. 

Sizing a heat pump system involves careful consideration of a number of factors: fabric of the building, air exchange rates, mean temperatures internal and external, insulation levels, etc.

Thermal Earth provides a full design and specification service which will accurately determine the heat load of the building. However, the design doesn’t stop there. We offer the following for heat pumps and underfloor heating:

  • Full heat load calculations of property to determine the necessary size of the heat pump
  • Design of ground collector for both horizontal and vertical systems
  • Specification of all components required to complete the installation
  • Design of heating system and schematic showing arrangement of components
  • Design of underfloor heating complete with spacing requirements, flow rates and temperatures
