Energycal LSQ Modular Heatpump

Energycal LSQ: Air source heat pump for large residential and commercial applications

The Energycal LSQ is a compact air source heat pump for DHW and heating. The units are designed to be mounted hard-up against each other reducing the space required, and creating a seamless multi-circuit heat pump. The cascade can consist of machines of different capacities, and therefore can be matched optimally to user requirements. The machines run extremely quiet over a wide range of operating conditions.


Upto 16 units in a cascade. Efficient across the entire operating range.  

A multi circuit heat pump system can be set up to optimally match user requirements by connecting up to 16 units in cascade. What’s more, the units need not be of the same capacity and the entire cascade is controlled by a single controller. The Variable Speed DC Fan is controlled by ambient air and leaving water temperature. The evaporator performance therefore closely matches compressor capacity at all time, and in conjunction with an electronic expansion valve ensuring highest performance factors with low consumption values.
