Description
ITS-6.3HDSuper 6.3 kW High-Temperature Domestic Heat Pump
The ITS-6.3HDSuper is a high-temperature residential air-to-water heat pump from the ITS Super series. It is designed for larger domestic hot-water requirements and combines a robust metal casing, an internal bronze circulation pump, R134a refrigerant and an advanced digital controller with built-in Wi-Fi and app control.
Rather than generating all of its heat directly through an electrical resistance element, the heat pump uses a refrigeration cycle to extract thermal energy from the surrounding air and transfer that energy into the water. This makes it possible to deliver substantially more useful heating energy than the electrical energy consumed under suitable operating conditions.
6.3 kW Heating Capacity and COP 4.5
The ITS manufacturer brochure lists a rated heating capacity of 6.3 kW with typical electrical input of 1.4 kW. The published COP is 4.5 under the stated test conditions. Actual operating efficiency will vary according to ambient temperature, incoming water temperature, required outlet temperature, hot-water demand and installation conditions.
High-Temperature Super Series
The ITS Super series is designed for applications where higher hot-water temperatures are required. The manufacturer brochure specifies a maximum heat-pump water outlet temperature of 80°C. The current ITS product page also highlights the Super-series ability to provide geyser temperatures above 60°C.
Built-In Wi-Fi and App Control
The unit includes an advanced digital controller with LCD display and built-in Wi-Fi. ITS identifies the Smart Life application for convenient remote control and scheduling.
Internal Bronze Circulation Pump
An internal bronze circulation pump is incorporated into the heat pump. This integrated design simplifies the hydraulic arrangement compared with systems requiring a separate external circulation pump.
Hot-Water Production for Larger Geysers
The manufacturer brochure lists hot-water generation of approximately 135 litres per hour when heating from 15°C to 55°C under the relevant test conditions. The current ITS product page markets this model for geysers up to approximately 500 litres, making it suited to larger residential hot-water systems when correctly sized.

Residential Applications
The ITS-6.3HDSuper is intended for larger residential domestic hot-water systems where increased heating capacity and higher-temperature performance are required. Correct sizing should take account of geyser volume, household occupancy, daily hot-water consumption, ambient conditions and required recovery time.
Installation Considerations
Professional installation is recommended. Performance and warranty compliance depend on correct hydraulic integration, suitable flow rate, pipe sizing, water pressure, electrical supply, airflow and positioning of the outdoor unit. Existing plumbing condition, geyser position, pipe routes and access can affect the installation scope and cost.
Manufacturer Specification Note
The current ITS product page and the manufacturer Super-series brochure disagree on a small number of fields. In particular, the current page lists 1015 × 420 × 620 mm and 70°C maximum water outlet temperature, while the brochure lists 1011 × 420 × 514 mm and 80°C maximum outlet. This product record uses the manufacturer brochure as the primary source for those conflicting technical fields. Always verify the documentation supplied with the physical unit before installation.
