I close the gas water heater on the balcony by the method of closing the valve of the shower in the

How do you want to control the switch if you don't control it like this?

The important design idea of the gas water heater is the "water pressure control control switch", that is, the water heater is automatically turned on and off according to the change of water pressure, which is the basic setting and has no effect on the water heater.

What you are talking about is the correct normal way to use, please feel free to use, if you do not use it for a long time, please go to the balcony to turn off the gas valve and cut off the power.

The water heater is installed on the balcony, first of all, there is no noise (because the gas water heater has the sound of fan exhaust), and the safety performance is also higher, but the water heater is far away from the water outlet point, and the cold water in the water pipe needs to be drained every time it is used, which is a waste of water resources.

It's completely normal to use, and there's no better way to use it.

There is no impact, now the use of gas hot water is controlled by the terminal, the gas has been turned on, because some units have 2 bathrooms, the kitchen also needs hot water, can not use one to turn off once, that is so troublesome.

I recommend installing a ball valve or triangle valve at the front end of the shower, because without a valve, the shower water is not very tight, and it is convenient to close the valve.
