GOODHEAT R134a commercial heat pump water heater in a hotel service courtyard

Heating capacity for

your building’s demand.

Three listed heating capacities support comparison across different commercial hot-water projects. Start with peak demand and recovery time, then confirm the unit performance at your design conditions.

Listed heating outputs: 17 / 33 / 70 kW.

 Evaluate accommodation and shared-facility requirements by project.

 Match heating output with the selected hot-water storage system.

Hot-water settings

from 28 to 75°C.

The specification lists a heating-mode water temperature range of 28–75°C with a default setting of 60°C. Select the delivery temperature around the project’s hot-water requirements.

Default heating setting: 60°C; cooling setting: 25°C.

 Confirm the operating envelope at the site design ambient.

 Cooling-mode water range: 18–30°C, as listed in the source.

Three output levels.

One clear comparison.

Compare listed output, electrical input and water flow together. The sheet gives COP values of 4.00, with the test condition to be confirmed.

Listed heating input: 4.25 / 8.25 / 17.50 kW.

 One compressor on the 5 HP class; two on the 10 and 20 HP classes.

 Point COP is not a seasonal efficiency or an annual savings guarantee.

Air moves upward.

Plan the space above.

The listed airflow direction is vertical. The cabinet uses top-mounted fans, so the project layout should preserve the required air path and access around the equipment.

One fan on the 5 HP class; two on the 10 and 20 HP classes.

 Declared ambient range: −7 to 55°C.

 Confirm model-specific clearances and installation dimensions before layout approval.

The source states three-phase power but does not specify a neutral conductor; confirm the wiring diagram rather than assume 3N~. Connection sizes retain the source millimetre notation and gender; thread standard is not specified.


Test conditions, noise metric/distance, dimensions, weight, compressor brand, refrigerant charge and water pressure limit are not provided in this sheet. Request the approved technical submittal for final selection. Water temperature and ambient limits are separate declarations, not a guarantee of 75°C water at −7°C ambient.
