COMMERCIAL HEAT PUMPS
HISA supplies R290 commercial air source heat pumps in 50 kW and 75 kW models for commercial, multi-residential and larger-building heating applications in the UK. Designed to operate individually or in cascade, with outlet water temperatures up to 75°C subject to operating conditions.
Tell us a little about your project and a member of the HISA team will get in touch.
Two model designations.
Output depends on operating conditions.
Maximum outlet water.
Subject to operating conditions.
Units in parallel.
Project-specific design required.
Refrigerant across both models.
GWP 3, as listed in the source.
01 / High temperature
High-temperature capability creates options for commercial heating projects. The right selection starts with heat loss, emitters, operating temperatures and the electrical supply—not the model number.
75°C is a maximum outlet-water temperature, not a guarantee at every ambient condition or at rated output. Suitability, emitters, heat demand and hydraulic/electrical design must be assessed for each project.
02 / Cascade
HISA commercial heat pumps support parallel operation of up to 16 units. Plan the arrangement around the building load profile, available space and project control strategy.
Individual heat pump
Coordinated operation
Project heating demand
03 / Controls & BMS
Bring building-management requirements into the design conversation from the start. Confirm the interface, equipment and configuration required for your project.
Features listed in the supplied source. Availability, accessories, network provision, integration scope and configuration must be confirmed with HISA. No live monitoring service is provided by this website.
04 / Applications
From new developments to existing estates, suitability depends on the actual building and its operating requirements.
Housing and apartment developments require a project-specific communal-heating assessment; the commercial range is not an automatic selection for every housing scheme.
05 / Technical library
Choose a model designation. Review exact performance records, source-listed specifications and original drawings without assuming that one duty represents every condition.
Performance
Model designations are not guaranteed outputs. Review the operating level and temperatures together, then confirm project selection with HISA.
Numerical 50 kW performance points are withheld while HISA verifies differences between the catalogue and supplied tables. The original catalogue curves are shown for reference only; no selectable figures are estimated from them. Obtain confirmed project data before equipment selection.

Heating capacity
COP —
Capacity curve for one operating level and flow temperature. Points are exact supplied records. Connecting lines are a visual aid, not interpolated data.
Each selectable value is an exact supplied capacity/COP pair at the same operating level, ambient temperature and water outlet temperature. Lines join measured points for readability, not interpolation. The structured data does not specify wet-bulb or water-inlet conditions; do not treat the full curves as the catalogue A7/6 test condition.

06 / Project support
Start with the building, not the product. Share the project stage, estimated heat demand, required flow temperature and any constraints so we can discuss the next steps with your design team.
Talk through equipment selection, cascade concepts, controls integration and the information needed for your specification. Final suitability and system design remain project-specific.
Commercial and non-domestic applications may be subject to separate warranty arrangements agreed by HISA.
