Frequently Asked Questions

What is the maximum water temperature this heat pump can provide?

The CO2 (R744) heat pump can heat water up to 90ºC-95ºC, making it ideal for high-temperature applications like disinfection and industrial cleaning.

Can this unit operate in extremely cold climates?

Yes, it is specifically designed for low-temperature environments and can efficiently provide heat even when the ambient temperature drops to -43ºC.

What are the environmental benefits of using R744 refrigerant?

R744 is natural CO2 refrigerant. It has a Global Warming Potential (GWP) of 1 and zero Ozone Depletion Potential (ODP), making it the most eco-friendly choice compared to synthetic refrigerants.

How does inverter technology improve performance?

The inverter control allows the unit to vary its power output based on real-time heating demand. This prevents frequent on/off cycles, leading to significant energy savings and more stable water temperatures.

What does the "Monobloc design" mean for installation?

The Monobloc design means all components are housed in a single outdoor unit. There is no need for complex refrigerant piping work during installation, as only water connections are required.

What is the energy efficiency (COP) of these units?

Under standard conditions, these units offer a COP of up to 5.5. Specialized multi-function models can reach a COP of 7 by utilizing free cooling while producing heat.
