Kensa has calculated costed examples for ground source heat pumps in large and medium-sized commercial buildings, to illustrate the costs and savings using both self-financed and funded split ownership models, compared to LPG alternatives.
Benefits of a cascaded system
Kensa heat pumps can be configured in a modular ‘cascaded’ configuration, providing a wealth of benefits for buildings with high heat demands.
A cascaded ground source heat pump system architecture can be effectively used to meet a high heat load, adjust to seasonal variations, maximise efficiencies of multiple temperature zones, add redundancy, and reduce overheating.Read more about cascaded systems
One of the many benefits of a cascaded ground source heat pump system is the ability to flex between periods of minimum and maximum heat demand; for example during the spring and summer when the need for heat is lower, only one heat pump need be in operation, with subsequent heat pumps coming into operation as the heating season progresses.
Costed Example: Large Commercial Building
This ground source heat pump costed example features a large single commercial building with a 515,000kWh annual space heating demand.
Kensa has calculated this example will require a 4000m2 area for the borehole ground array infrastructure.See example costs
Costed Example: Commercial Building
This ground source heat pump costed example features a smaller single commercial building with a 102,500kWh annual space heating demand.
Kensa has calculated this example will require a 500m2 area for the borehole ground array infrastructure.See example costs
Summary: A cascaded ground source heat pump system links a central ground array infrastructure to a number of large modular ground source heat pumps cascaded together all in one central plant room. Cascaded ground source heat pump systems can adjust between minimum and maximum heat demand as needed. Cascaded systems can also be designed with one or…
If your commercial premises has a high demand for heating and hot water exceeding 75kW, an effective solution is to configure Kensa’s ground source heat pumps in a cascaded system.
