Question:

The electric water heater is out of water

The electric water heater is out of water

Answer:

The first use of the hot water valve is opened (by red) (air mixing valve to the red end) then open the inlet valve, (the blue) and water (water inlet valve), then the outlet (shower) air only, this time must be careful not to contact, no power plug can be inserted!!! Over a period of time of shower water, then close the cold water mixing valve, valve not closed, open, and then plug the power supply, open the power supply, for heating,...... For the first time, 1-2 hours later, you can use the hot water mixing valve open, with the open with the use, the inlet valve open not closed.
We must first side to the water heater inside the water inlet side of the hot water shower to open the discharge air, because the first tank is empty, cold water inlet and water tank will have a lot of pressure, if not exhaust air is not filled with water, air exhaust has been discharged into the water when you shower normal means water heater inside who have almost the same!
First of all, the tap water valve should be opened and loaded with water. When the tank is filled with water, there will be air flow and water from the nozzle. When there is no air flow, the water in the tank is full, and then the electric heating will be made.
