When a price has been quoted and accepted and a deposit received, the installation of the ground loop is arranged and the heat pump will be ordered. We carry out the installation of the ground loop and the installation and commissioning of the heat pump ourselves, in accordance with the “Good Practice” guidelines stipulated by the Energy Saving Trust.
Ideally the ground loop installation takes place during the major ground works of a new build. This reduces future ground disturbance, may utilize favourable rates from the builder for digging trenches and allows time for the thermal gradient to be restored. Additionally, you may of course want the land to be landscaped to form a garden. However, installing a ground source heat pump to an existing building is still possible.
The installation of a horizontal ground loop is a simple process. The correct length depth, width and spacing are calculated. These specifications will be passed on to the ground work contractor. The trenches are dug and our engineers lay the piping the following day. The pipe is terminated at the manifold (on the external side of the wall, usually at the point at which the heat pump is to be installed internally). The trenches are then back filled, leaving no trace of your heating fuel supply.
The heat pump needs to be ordered about 6 weeks before heating is required. The unit is delivered directly to the customer and our engineers will carry out the fitting and commissioning and testing. Electrics and plumbing will have been specified in advance and provided as part of the build. Commissioning takes less than one day and involves filling, purging and priming the ground loop and the heat pump unit.
It should be noted that heat pump systems are sized to provide efficient heating and should not be used to “dry out” a newly built property. Industrial heaters can be hired for this purpose.
