Modified Capacity Shared Ground Loops

Energy • Engineering • Environmental

Add capacity to your GSHP and benefit from your existing tariff for both systems.

If you have a non-domestic Ground Source Heat Pump on the RHI tariff with more capacity than you are using, you could benefit from extra output from your existing system through the option of “modifying capacity”. [This does not include extending your existing ground array.]

Any modified capacity added to your system will be paid at your original certification rate and is pro rata from the time of the additional installation to the end of your existing RHI agreement.

For applicable clients, this presents an exciting opportunity to further generate revenue and offset your carbon footprint…

  • There is no need for any in-ground works as this is an addition to your existing ground array.
  • You will get paid on your original tariff rate for the additional capacity for the remainder of your tariff
  • The additional heat CAN’T be used for process heating but CAN be used for space and water heating and various other processes such as aquaponics, production sheds, vertical growing etc.
