1. The Nen rate magnetic levitation moving coil gas proportional valve is a patented technology. The whole series is equipped with a proportional valve imported from Japan as standard. Rinnai is a moving rod type. 2. There are 6 coils in the Nen rate heat exchanger. Rinnai 5 wires. Ordinary machines with more than 1,000 units only have 3 wires? From this aspect, we can see that the Neng rate configuration is more solid. 3. The water inlet and outlet pipes and water tanks in the forest are all spliced ??and welded. The Neng rate is integrated from the water tank to the water inlet and outlet. You don’t have to worry about long-term use. There will be water leakage problems. 4. There are temperature sensors at the water inlet and outlet of Nengli, but only the water outlet of Rinnai. 5. Nengli and Rinnai offline have imported CPUs with the same functions. Nengli does not have as many as Rinnai advertised, so it will be about 400 cheaper. Norate started out as a gas major, and Rinnai switched to the stove industry. To sum up, I think Norate is better than Rinnai in terms of configuration and function. The price/performance ratio is a little higher, and Norate has a higher market share in Japan. From this, we can see which one is better. Better yet.
