1. High efficiency frequency conversion technology

With more than 40 years of experience in heat pump R&D and manufacturing, our high-efficiency inverter technology not only saves energy for users, meets comfort requirements, but also reduces product noise and does not pollute the environment.

Ordinary heat pump VS STIEBEL ELTRON inverter heat pump

Ordinary heat pump: The compressor only works at two speeds, full speed or off. However, the actual heating demand is a continuously changing analog quantity, not a switching quantity. This leads to deviations between the working state of the compressor and the actual heating demand, and the final result is that the compressor works in a high energy consumption state most of the time, resulting in waste of energy.

STIEBEL ELTRON high-efficiency variable frequency heat pump: The continuous rotation speed of the compressor can be controlled according to the actual heating demand. When the demand is high, the speed is fast, and when the demand is low, the speed is reduced. This ensures that the heating demand is greatly reduced, and the energy consumption is greatly reduced, and the working noise is also reduced.

STIEBEL ELTRON HPA-O 13 C(S) Premium Air Source Heat Pump:

- The energy efficiency ratio (COP) reaches 5.09 at an ambient temperature of 7 ° C and a water temperature of 35 ° C.

- Seasonal energy efficiency ratio (SCOP) reached 4.76

- For noise control, the sound pressure level (5 m free field) is 32 dB (A), similar to the sound environment in the library.

2. Bare wire heating technology

Heating tube heating VS bare wire heating

* The bare-line water heater technology requires a special insulation system between the live part of the bare-line heating element and the water at the inlet and outlet of the appliance to ensure the protection of the live part.

* The insulation system consists of water pipes located at the inlet and outlet, with the heating element located between the two (see figure). These pipes are made of insulating plastic.

* The length, cross-sectional area and specific conductivity of the pipe determine the resistance of the pipe.

*Import and export are made of metal and grounding meets Class I appliance standards.
