Groundwater Source Heat Pumps
Code of Practice

CIBSE, GSHPA and the HPA are publishing a code of practice for Open Loop Groundwater Source Heat Pumps.

The Code of Practice, which is being produced by a steering committee with lead authorship from Nic Wincott and Jen Billings of the GSHPA, will be available from

Electronic copies will be available to members of the GSHPA, without charge. Please request a copy via

Installation of Ground Source Heat Pumps

To get the full benefit of a GSHP installation or a GWSHP you will need to employ someone with design and installation experience. A groundwater source heat pump, like a ground source heat pump, may not perform well unless it is incorporated in a good design by someone who understands the needs of the building, the use to which the building is being put and the local geology.

To ensure a "soft landing" you should ensure that a ground source system is well understood and well maintained and this may include fine tuning the controls in the first years of operation.

For more information on installation of ground source heating from an experienced source please contact one of our members.
