Which brand of water heater is good? Do you have any recommendations?

As far as the service life of the water heater is concerned, I still recommend the water heater of Weineng in Germany. The world's first gas water heater with constant temperature control was developed by Weineng, so its family must have a lot of experience in making water heaters. Because it is also a big German brand, it pays attention to high efficiency, energy saving, durability and waterproof, so don't worry about its service life.
