It extracts heat from ambient air through a refrigerant cycle and transfers it into water, producing hot water with a COP of 3-4 and cutting water heating energy costs by roughly 70% compared with electric heaters.
Commercial models range from 20 kW to 400 kW, suitable for hotels, hospitals, schools, swimming pools and industrial process hot water.
Yes. Ultra-low-temperature models are engineered to work reliably down to about -25°C ambient, using enhanced vapor injection compressors to maintain heating performance in winter.
A single unit can supply multiple insulated storage tanks through a circulation loop. We also provide matched tank and controller packages for complete hot water systems.
No. Connect the water pipes and power supply, set the controller, and the unit self-adapts. Our engineers provide remote commissioning guidance for every project.
