Storage indirect water heater: operating principle, connection, feedback

Water heaters indirect heating of water in recent years are in great demand. In terms of size, the models are quite cumbersome. The nominal power rating starts from 2 kW. For larger families, this type of device is great. Before buying a device, it's important to consider the performance. At the same time, the completing materials play an important role. In order to understand in more detail the water heaters of indirect type, one must understand the principle of their operation.

Principle of operation of the device

A variety of indirectly heated water heaters are on the market. The principle of the devices is to heat the spiral element. Initially, the voltage from the 220 V network goes to the power supply. Then the control system is activated. The inlet pressure of the device depends on the valve. In order to protect the system from overvoltage a fuse is necessary. The temperature of the water is controlled by the controller. Conductivity heating elements are quite different.

The water is supplied through a pipe. In some cases, a flexible hose is used. The heat medium is connected to the insulator. When the power of the model is increased, the heating spiral element inside the tank is heated. Heated water comes through the outlet pipe. In this case, the control unit is used with a stabilizer. The temperature limit is controlled by a thermometer.

How to connect the device?

Connecting the indirect heater is quite simple. First of all, the tank is fixed directly. Most often, horizontal stops are used for this purpose. In this case, much depends on the size of the water heater. After fixing the tank, proceed to connect the pipe to the water supply system. For this purpose, a metal clamp is used. Direct connection in devices is provided screw type. The outlet connection is connected to the mixer. Connect the network cable to the power outlet.
