Frequently Asked Questions

How does an air-source heat pump water heater work?

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.

What capacity range does DERK offer?

Commercial models range from 20 kW to 400 kW, suitable for hotels, hospitals, schools, swimming pools and industrial process hot water.

Can it operate in cold climates?

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.

How many water tanks can one unit supply?

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.

Is installation complicated?

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.
