Heating System Specification Services

When installing an air source heat pump, it is essential that the system is correctly designed and sized. Low-temperature heating systems, such as a heat pump, have specific design requirements which must be met to ensure that the system can successfully meet the heating demand of the property. Grant UK’s Design and Specification Team are on hand to help heating professionals plan and specify for air source heat pump installations.

Tailored support

A range of free and chargeable services are available to support heating engineers, merchants and specifiers with their upcoming Grant air source heat pump installations. The following services are free of charge:

  • Heat loss estimates (when customers require a whole house heat loss)
  • Basic Heat Loss Calculation (when customers require an in-depth room-by-room heat loss calculation)
  • System quotations (supplying customers with a list of products required for the system installation)
