Omusha integrated water heater must be easy to use, because Omusha adopts the most advanced 3D MAX stereo surround heating technology, and the water and electricity are completely separated, which is safe and efficient. Ten years of zero failure!

Smith water heater is too miscellaneous and rotten. What they sell most are vats (storage water heaters) that have long been banned from production and sales in Europe and America. They consume a lot of electricity and are difficult to clean, not much better than heating rods!
