To understand the installation principle of the storage water heater, it is necessary to know the technical characteristics of the equipment.
Storage water heater is a cylindrical tank of vertical and horizontal type, designed to heat water from 55 to 75 using electric heaters. After heating the water to a predetermined temperature value, the water heater switches off and switches to automatic temperature maintenance mode.
Advantages and disadvantages
Heating coil of the boiler
The advantage of storage water heaters is that they are universal and do not require large energy costs. Their installation is allowed in any rooms where there is electrical wiring and plumbing.
In addition to these advantages, there is one more and no less weighty plus - the use of water from the tank in several places at the same time. From the storage water heater produce a supply to the main water valve, where the water is distributed. The only disadvantage is that its dimensions make it impossible to install them in small rooms and in tight spaces.
If you are faced with a choice and do not know which of the two types of water heaters to choose, then the best and economical option, of course, will be a vertical water heater. This is explained by the fact that in the vertical water heater of the heating element is located in the lower part of the tank. And have a horizontal heater in the side. As a rule, cold water falls to the bottom of the tank. For vertical water heaters, its heating is not difficult.
Horizontal storage water heaters cope with the water heating worse. As a result, energy consumption increases.

What can affect the durability of the water heater?
Storage water heater device
First of all, the water quality affects the durability of the storage tank. If you use water that is saturated with iron, it is best to use an enamel tank. In enameled tanks put large protective anodes, they will neutralize the active components of iron. The only requirement is a regular replacement of the protective anode.
As for stainless steel storage water heaters, they are supplied with small protective anodes. Therefore, when using ferrous water, the anode does not cope with the load, and iron is deposited on the surface of the tank and on the heaters. As a result, it is necessary to change the tenu and anode at the same time.
Operation principle
There is one more nuance that affects the durability of the water heater - this is the operation of the water heater device. Improper operation of the device in the winter season leads to the fact that the water tank freezes, resulting in the bursting of the heating elements and protective anodes. The joints begin to flow, as a rule, this leads to premature disposal of the water heater.
Accumulative water heaters are made with one and two heating elements of different capacities - 1.5 and 2.5 kW. A heater with two heating elements is installed in places where consumption of large electric power is foreseen.
The heater with one heater is designed for low-power electrical lines.
Installation locations of the storage water heater
Installation under the sink
Most The ideal place to install the appliance is the lower part of the wall under the sink. Thus, the space is not cluttered and the risk of the tank breaking under the weight of the water mass is reduced. Do not be afraid of the fact that on the surface and on the places of the connecting elements will splash water. Manufacturers of water heaters have worked on the electrical safety system and designated the degree of protection on the body of the water heater. Therefore, before installing a storage water heater, familiarize yourself with the labeling.
Mounting fasteners
Fixing the heater to the bracket
Mark the installation location of the fasteners and install anchor bolts or hooks. Anchors and hooks are installed using an adjustable wrench, and they are clamped with full force. After fixing the fasteners, the nuts are unscrewed from the anchor bolts and a tank is put on the anchor, after which the nuts are clamped.
The choice of fasteners is selected according to the displacement of the tank.
Water supply to the water heater
Water supply to the boiler
To facilitate the water supply to the water heater, it is necessary to begin with the supply of cold water. The inlet port of the nozzle is marked in blue, the outlet is inserted into it with a pre-wound layer of tow soaked in silicone.
A tee is screwed onto the treated nipple and an emergency drain valve, a relief valve and a shut-off valve are mounted in each hole. At the end of the installation of valves and valve on the tee install a threaded adapter and connect to the apartment plumbing.
Next, go to the hot water. On the hot water system, we install a shut-off valve and a threaded adapter, it will serve as a link between the apartment wiring and the hot water pipeline.

Rules for connecting an electric water heater:
Wiring
Connection of the boiler to electrical networks
Prepare a cable with a square cross section of 2.5 squares and an automatic circuit breaker of 16 A. Then connect the wiring to the electrical panel and fasteners in the tank according to the attached instructions.
