Capacity for commercial demand.

Choose from three listed capacity classes for central hot-water projects. At the stated standard test condition, heating outputs are 52, 75 and 115 kW.

Compare hotel, accommodation and shared-facility demand by project.

Select against peak draw-off, recovery time and storage volume.

Capacity varies with air and water conditions.

Outlet water up to 70°C.

The specification lists a maximum outlet water temperature of 70°C for all three models. This supports evaluation of higher-temperature hot-water requirements.

Standard performance is rated for water heating from 15 to 55°C.

Maximum outlet temperature is separate from the rated performance point.

Confirm the permitted temperature at the project design ambient.

Hitachi inverter.

Three capacity choices.

All three columns specify Hitachi inverter compressors. Standard-condition COP values are 4.65 for the 50 kW class and 4.25 for the 75 and 115 kW classes.

Compare heating input and output at the same test condition.

Rated heating input: 11.18 / 17.65 / 27.10 kW.

Project consumption depends on operating conditions and demand.

Performance data

for colder conditions.

The declared ambient operating range is −15 to 45°C. Separate air 7/6°C and −7/−8°C ratings help assess capacity at colder design points.

At air −7/−8°C: 27.61 / 43.71 / 85.42 kW heating output.

The low-temperature test heats water from 9 to 55°C.

Do not apply standard-condition output to minimum ambient.

Water-side details.

Ready for selection.

The listed water-side heat exchanger is coaxial. Connection sizes, rated flow, unit weight and dimensions are provided separately for each capacity class.

Connections: DN40 / DN50 / DN65.

Maximum water pressure: 1.0 MPa; enclosure rating: IPX4.

Check access, structural loading and top-discharge clearance.

The maximum water temperature and minimum ambient are separate listed limits. The source does not establish 70°C output at −15°C ambient. Obtain the complete operating envelope for the ordered version.


The noise row does not identify sound pressure / sound power, distance or test condition; do not describe it as a 1 m sound-pressure rating. The source hot-water-output rows are labeled only “L”, with no time basis: they are excluded from rate claims pending clarification.

Build the brief.

Confirm the design point.

Why is the 50 kW class shown as 52 kW?

The workbook labels the model column “50KW” and separately declares 52 kW at air 20/15°C with water heated from 15 to 55°C. Both are retained without treating the capacity label as an order code.

Can the unit deliver 70°C at −15°C ambient?

How should I compare the COP values?

Does this page include a PV direct-driven version?

Can the products be controlled in a cascade?
