Water heaters for indirect water heating have recently been in great demand. In terms of dimensions, the models are rather bulky. Their rated power parameter starts from 2 kW. For large families, devices of this type are great. It's important to consider performance before purchasing a device. In this case, component materials play an important role. To understand in more detail the indirect type water heaters, you need to understand the principle of their operation.

How the device works

There are a wide variety of indirect water heaters on the market. The principle of operation of the devices is to heat the spiral element. Initially, the voltage from the 220 V network is supplied to the power supply. Next, the control system is activated. The inlet pressure of the device depends on the valve. A fuse is required to protect the system from overvoltage. Water temperature setting is carried out thanks to the controller. In terms of conductivity, heating elements are quite different.

The water is supplied through the pipe. In some cases, a flexible hose is used. The coolant is connected to the insulator. As the model power increases, the heating coil inside the tank heats up. Heated water enters through the outlet. In this case, the control unit is used with a stabilizer. Limit temperature control is carried out thanks to a thermometer.

How to connect the device?

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