May I ask all the gods in the installation of gas water heaters, I don t know how to install an inne

It can be used, but the pipeline is too long, resulting in cold water every time you use hot water, until the hot water flows out, which will waste a part of the water, and after deactivation, the hot water in the pipeline will soon become cool, so it is water-consuming and exhaust gas, it is recommended that you install a thermal insulation bucket-type electric water heater at the use end, every time you start the gas water heater to heat the hot water of a thermos bucket and then use the end remote control to turn off the gas water heater, sporadically use hot water from the thermal insulation barrel without starting the gas water heater, the advantage of this is that The gas water heater starts very few times, avoiding the waste of water and the heat loss of the pipeline, and reducing the number of starts is of great benefit to the service life and safety of the water heater, while the electric water heater at the use end is only used as a thermal insulation barrel and does not have to be electrified. The gas water heater is only activated when the thermos bucket is stored with hot water and when a large amount of hot water is used continuously.
