What's the difference between ptc air energy Yuba and ptc air energy Yuba?

After reading some so-called introductions of ptc air energy bathroom, I feel that I am still playing word games. PTC is PTC, and the performance is still the performance of PTC (it can be heated with high power at low temperature, and the power can be automatically adjusted after the temperature rises). More importantly: "air energy bathroom, unique ionization heater (core patented technology), instantly ionizing air molecules, air molecules collide internally, and their own energy quickly gathers and conducts outward, similar to one. The cost of nuclear power is only one-third of that of thermal power, and the energy consumption of air energy Yuba is only one-fourth of that of traditional Yuba. " It's total nonsense! The efficiency of direct electric heating is just like this, and there is no possibility of generating additional energy. So I think ptc air energy yuba and ptc air energy yuba are the same thing, just playing with the concept.
