You will need
  • flexible water hoses in a metal braid, 2 crane 0.5 inch, wrench 22/24, ribbon Fuma (special soft tape, designed for sealing threaded connections), power outlet (Euro) with grounding, wiring, brackets for attaching the heater to the wall, a screwdriver.
Electrical accumulative water heater (boiler) heats the water to 55-75 degrees, and then maintains the temperature automatically. Since heating takes place gradually, such apparatus does not require large electric costs. Even the 150-liter water heaters consume no more than 1.5-2 kW. The capacity of the storage water heater can range from 10 to 500 liters.
In flow-through water heaters the water is heated instantly, passing through the heating element of large capacity (capacity from 6 to 27 kW), therefore, the heaters of this type are immediately removed from the network more compared to boilers, the amount of electricity. On the other hand, instantaneous water heater can issue an unlimited amount of hot water and does not require regular maintenance.
Gas instantaneous water heaters provide hot water. They are safe in operation: the safety valve with the thermocouple will block the flow of gas if the burner accidentally goes out. The ignition device is fully automatic and requires no adjustment, while ensuring complete combustion of the gas during start-up. In gas water heaters can smoothly adjust the water temperature, the automation will ensure its permanence, regardless of fluctuations in water pressure.
For fixing on the wall water heaters take the brackets with the hooks, secure them firmly to the wall. On the back side of the heater there is a special hanging device with two holes. Hang the heater on the brackets.
Now you need to bring cold water to the device by screwing the pre-to the intake valve ball valve and to the valve to screw flexible hose that connect to the water supply. The output of hot water put the tap, from the tap output hot water pipe hot water, which will go to the bathroom and the kitchen. At the same time the tap for the intake of cold water and tap hot water outlet, do not forget to open a hot water tap, for example, in the bathroom so the air came out of the water heater tank. When the water goes from the bathroom faucet, the tank of the water heater filled with water.
Now you need to connect the water heater to the electric network. For this we need to install the socket (Euro) with a grounding contact, to bring to her a electric wire with a diameter of not less than 2.5 mm, it is better to separate the line from the meter. Ground in a separate building is best done in the cellar, scoring the iron area in the ground not less than 1 meter.
Insert the plug of the heater into the outlet. Turn on the water heater START button (Power, select the temperature level. After about an hour the water is heated, and the heater is ready for operation.
