This section provides details of an example project featuring a cascaded ground source heat pump system fed by a pond mat ground array.
We have provided schematic drawings, example costs and a real-life case study to showcase how a cascaded ground source heat pump system architecture designed by Kensa can effectively meet a high commercial heating and hot water load.

* A cost range is depicted here as every project is different and can contain more design features than shown in this example **Installation costs for external kit only (costs to install internals equivalent to a traditional system) ***NDHRI is a 20 year index linked funding stream which assumes inflation at 3% ****Based on electric at 15p/kW/hr and COP of 3 *****Based on LPG at 40p litre and 85% efficiency
