The absence of hot water in the house can be associated with a number of reasons: interruptions in DHW supply, seasonal shutdown, etc. From this situation there is quite a logical way out - the connection of the water heater. You can do it yourself. And then the question arises: "How to connect the water heater?" To begin with, you should familiarize yourself with its design features, type of execution, and also the connection diagram.
It is worth saying that electric heaters are of two types: accumulating and flowing. In the design of the flow enters the heat exchanger, through which passes cold water and immediately heats up. The storage is equipped with a thermally insulated storage tank, the volume of which varies within the range of 5-1000 liters, where the water is continuously heated by means of a ten. For household appliances, the power consumption is usually 1-2 kilowatts. So, if we talk about how to connect a water heater, then it is worth considering a lot of nuances.

Often such devices are equipped with an automatic system designed to set the desired water temperature. It is widely believed that the use of such a water heater leads to significant costs for electricity. This is a delusion, since even with a large power consumption it works much less time than a storage heater. Only the used part of the water is heated. This leads to the fact that the same amount of electricity is consumed. The main drawback is a large power consumption. That is why when answering the question "how to connect a water heater" it is worth noting that special requirements are imposed on the electrical wiring.
To connect a flow heater, you need to extend a separate line with individual electrical protection around the house or apartment, otherwise you can stay without light after mounting the heater. It is best to use a copper wire of 4 square millimeters or more. For a device with a capacity of 8 kilowatts, the cross section must be at least 6 square meters. Mm.
If we talk about how to connect a storage heater, it should be noted its lower demand for wiring, which is associated with a lower power consumption - only 1-2 kilowatts. However, in houses with old wiring, it will be more correct to insure yourself by conducting a separate group with an automatic machine connected through it. A copper wire with a cross section of 2.5 square millimeters is quite suitable for these purposes.
If you understand how to connect a water heater, then it is worth mentioning the advantages of its storage type. First of all, its advantage is that it allows you to heat water for the bathroom, as well as to serve simultaneously in several taps, which is sometimes necessary. In the event of a power outage, there will be some hot water in the house.
