Proper installation of a water heater in an apartment or a private house is a universal solution to ensure uninterrupted hot water supply. The condition is especially relevant for residents of apartment buildings, where the hot water supply is periodically turned off (seasonal pressure testing of pipes, prevention, diagnostics, repairs, etc.).
In one of the articles, we talked about.
So, the choice was made, all proposals for installing a water heater by "masters" for space prices were rejected, and it was decided to install the boiler on our own. There is nothing supernatural about the connection, but some tool and attention will be required.
Do-it-yourself storage water heater installation
Before proceeding with the installation, it is recommended to determine the bearing capacity of the wall where the heating device will be installed. Will it hold up? Still, the weight will be rather big. If there is doubt about the strength of the wall, then you can build a supporting stand or some additional brackets for the device.
Since there will be no immediate need to regulate the temperature, we do not consider the distance from the point of use in our case - we install the boiler where it is convenient for us.
Otherwise, everything is the same as in the case of: we drill holes, drive in dowels and fix the water heater.
Connecting the storage water heater to the water supply - diagram
Installing a storage water heater requires a more thorough approach. In addition, it allows you to use hot water from the appliance throughout the apartment.
In the diagram, we see a typical connection of a water heater (accumulative) to the water supply.
Notation "hot water" and "cold water"- these are "risers" - two pipes that pass through all the apartments of the entrance and supply them with water (cold and hot).
1-2 - water taps. They block or open the circulation of water to the tank and back from the water heater. When the device is working, the taps are opened, if not used, then, of course, they are closed.
3-4 - water taps introductory to the apartment. They are necessary to shut off the water supply to the apartment.
5 one of the important elements check valve. It is necessary to protect the heating element of the electric water heater from overheating (in the event of a shutdown of cold water, the water heater tank is not left without water and its heating elements will not burn out).
For understanding, let's turn to the device of a storage water heater, the principle is as follows: water is supplied from below. And if suddenly the water supply is suddenly turned off - all of it will rush into the already empty riser with cold water, the heating elements will heat the air and simply burn out. The check valve is designed to prevent such an accident.
Any good storage water heater includes such a protective device. Be careful when checking the package!
6 - drain valve- a tap that is designed to empty the storage tank of the water heater. For obvious reasons, such a tap must be provided during the installation of the water heater: before dismantling (if necessary) the water heater, it will drain all the water from the tank. After all, depending on the capacity of the water heater, there can be 100-150 liters of water in the tank ....
Attention to the diagram: it is imperative to place a tap for draining water above the check valve. Otherwise, you will not be able to empty the tank - water simply will not flow out of the tank.
How to use the water heater taps (closing and opening)
"1" and "2" will be needed to turn off the water when the electric heater is not in use. For example, if we needed to remove the last one.
Cranes indicated in the diagram by numbers "3" and "4" available in any apartment connected to the central water supply, located after the risers, because we sometimes have to turn off the water for various reasons.
Let's look at the faucet "4"- it blocks the circulation of hot water between the apartment and the riser during the operation of the device. If the tap is not closed, then all residents of the entrance can use hot water from our water heater - the water will go to the riser.
Main rule of use- if hot water is supplied by the city boiler house, the water heater is in the off mode - "1" and "2" taps are closed, and "3" and "4" are respectively open. If the boiler room "gets up" for prevention and the hot water is turned off, we connect our device to the 220V network, open the taps "1" and "2", and close the tap "4".
Scheme of connecting the storage water heater to an open tank
In private houses, cottages or in the country, where there is no centralized water supply (or for other reasons), water storage tanks are used, which, as a rule, are located on the roof. This is not a limitation for using the water heater. The only thing is that the distance from the device to the tank must be at least 2 m, and if the pressure in the water supply is more than 6 bar, then it is necessary to install a reducer (at the inlet, in front of the boiler) to reduce the pressure.
Depending on the distance from the upper point of the boiler or pumping station, different connection schemes are used.

Connecting the water heater to the mains
Since the operation of the water heater requires a connection to a 220V network and mandatory grounding, the best option would be to connect to an existing outlet for a washing machine - through a plug (of course, provided that this outlet is wired in a separate line in compliance with the rules).
If the apartment does not have such an outlet, then it would be best to turn to electricians for qualified help in laying electrical wiring. There are several reasons for this.
- First, working with electrical wiring requires certain skills and knowledge, and if certain points are not observed during installation, it threatens with electric shock or failure of electrical appliances.
- Second, you will have someone to ask for poor quality work. Of course, if you have concluded an agreement with a contractor.
- And finally, there will be no problems with which wire to choose, which machines to install.
Perhaps this will prompt you to conduct an audit of the electrical wiring throughout the apartment.
Well, in conclusion, I would like to wish you pleasant water procedures.
