The patent of motorcycle proportional valve says so.

1. energy rate magnetic levitation moving coil gas proportional valve is a patented technology. Proportional valve imported from Japan is standard in the whole system, and the forest is a moving rod type. 2. There are 6 coils in the energy rate heat exchanger, 5 in the forest, and only 3 machines with average 1000. It can be seen from this aspect that the energy rate configuration is more solid. 3. The water pipes and water tanks in the forest are spliced and welded, and the energy efficiency from the water tank to the water inlet and outlet is integrated, so there is no need to worry about water leakage for long-term use. 4. Both the water inlet and the water outlet have temperature sensors, and there are only five water outlets in the forest. On the premise of the same energy rate as the imported cpu under the forest, the energy rate is not as much as that of the advertisement under the forest, so it will be about 400 cheaper. The energy rate starts with gas specialty, and the forest is a stove. To sum up, I think the energy rate allocation function is better than that of forest, and the price is higher, and the energy rate has a higher market share in Japan. We can see which is better.
