If your commercial premises has a high heat demand exceeding 75kW, the largest capacity capable of a single unit manufactured by Kensa Heat Pumps, an effective solution is to link a series of Kensa ground source heat pumps in a modular cascaded system.
Ideal for buildings with a required flow of up to 50°C, any high heat load can be matched with a cascaded system, as the central ground array is sized to deal with the peak heat demand
Find the recommended cascaded ground source heat pump design for your commercial building project and establish the heat pump installation costs using our costed examples.
Cascaded solutions for businesses
Benefits of a cascaded system
The cascaded system design can 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.
Another benefit of the system design is that, depending on the heat pump selection, it can be configured to provide 60°C hot water at the same time without the need for an additional immersion heater.
Costed example for water source
If your business premises has access to a stream, river, pond or lake, then you should consider using this as the heat source for your installation.
Water is an excellent conductor of heat and therefore water source ground source heat pump systems are extremely energy efficient.
Kensa Contracting provides a complete turnkey service from feasibility study, through to design, full project management as well as installation and commissioning. And of course the heat pumps are manufactured by Kensa Heat Pumps, too.
If you or your own preferred installer will be undertaking the installation, Kensa’s MCS Umbrella Service offers full MCS compliance for those who are not yet MCS accredited, or simply require design support.
Guy Cashmore, Technical Director for UK manufacturer Kensa Heat Pumps, clarifies what is meant by the term ‘cascaded ground source heat pumps’; and what this type of system architecture can bring to commercial projects with high heat loads.
