So the electric water heater doesn't keep under pressure. Is it possible to install the valve? 40
Electric water heater, the water heater as we all know, burning electricity, burning gas, electric water heater, as we all know, is to use water heater and electric heating, but the water heater is the most important one is "hot", namely after the heat is boiling water and electricity immediately. There is hot water, so called hot type.
Not quite understand what you mean, the installation of a water inlet valve can adjust the angle of the influent quantity size, electric water heater is a hot water and cold water inlet, is heated to a high temperature when the internal pressure will increase, is to close the angle valve inside there is pressure, don't worry. That's what the design room takes into account.
Generally speaking, the pressure refers to the pressure of the tank, rather than the pressure of the water supply (the highest is also more than a dozen kilograms). If the angle valve is closed at the inlet, the user will not turn on the hot water valve when it is normally heated. At this time, the liner inlet and outlet are closed, still heating, equivalent to a boiler! Very dangerous!
The risk of pressure in the water heater line is far from the danger of dry fire. If the dry - burning device fails or the heating of the heating element is dried by mistake, the heating element will be burned at most one or two minutes. Therefore, the installation of imported control angle valve is prohibited. But if the water pressure is too high, install the pressure reducing valve (regulating valve).
