Buy a water heater is not all. It still needs to be installed, and then connect. Moreover, connect to the water supply, and to electricity. How to install the water heater depends on its type: flow or accumulative. Depending on the size and shape, the installation location is selected. The requirements for the power supply line are dependent on the power, and from the internal device of the water heater - the diagram of connecting to the water supply.
Types of electrical water heaters
There are two large groups: flow and accumulative. Flowing water heaters are heated by water, which passes through them. In this regard, there are relatively small sizes, but very high power - up to 24 kW, but this is a maximum. For washing dishes and taking the soul, there is enough power in 4-6 kW, for the adoption of the bathroom - 10-12 kW. So, to connect such equipment, a dedicated power line is required from the RCD.
Water heaters of different types
Cumulative water heaters are called "Boilers", they have a tank and a small, compared to flow, power - from 0.8 kW to 4 kW. However, a separate power supply line is also desirable for them. The size of the boilers depends on the volume of water, which is contained in the tank. The form is cylindrical, and the cylinder can be vertically (a cheaper option) and horizontally (cost more).
The location for installing the water heater is chosen mainly depending on the existing connection conditions. Most often it is or a bathroom or kitchen: water is connected in both rooms. In second place, the place is selected from aesthetic considerations: so that the equipment is not very "rushing" into the eyes. From this point of view, a toilet or bathroom is usually chosen. If there is a place, this choice is optimal.
How to install a boiler (storage water heater)
Let's start by mounting on the wall, because it is usually fixed there. Empty boilers have a solid weight, and even water contains up to 150 liters. Therefore, strict requirements are presented to the fastener: they must withstand double weight equal to double tank. That is, if you have a boiler for 80 liters, the fastener must withstand 160 kg. In this regard, it is mounted only on the basis of a good bearing ability to anchor with hooks.

Holding a boiler on the wall
On the rear wall of the water heater, there is a mounting plate (sometimes two of them - at the top and bottom). It has slits in which the hooks are doing. So the boiler is hung on the wall. There are two different ways to note where to drive fasteners:
- If there are helpers and space allows you to move relatively freely, you can lean the boiler in the right place to the wall, after which there is a breakdown.
- Measure the distance on which the plank is from the top of the water heater, measure the distance between the centers of the mounting holes. To postpone all these parameters on the wall, finding the necessary points.
One nuance: If you are going to hang the water heater under the ceiling, it is necessary that there is no less than 5 cm from its top to the ceiling to the ceiling. It is necessary that it is possible to raise it, planting on the hooks. Otherwise, the boiler will not work.
How to connect a boiler to the water pipe
We will proceed from the fact that the cutting point of cold water is already there, as well as a combination of hot water wiring. A little about how to connect the exits of a boiler with a hot and cold water pipeline. It is more convenient to use flexible hoses, but not those that are just a rubber band in braid, but flexible from corrugated stainless steel. They also have different lengths, have at the ends of the cape nuts with gaskets, but their service life and reliability are several times higher. If the boiler hangs over the bathroom and all the connections are there in the same place, even in the case of a gust of the hoses, you do not threaten anything: water will be in the bathroom. If not, you can flood your neighbors.
Another option is the use of plastic (polypropylene or metal-plastic) pipes. This option is used if the hot water is placed at the same time by distribution points. Otherwise, it is more convenient to use flexible connectors. Only when using pipes, keep in mind that there are special pipes on hot water, on which the labeling is usually applied in red, it may not be completely on pipes for cold water, or it has a blue / blue color.

Now directly about the scheme of connecting the boiler to the water supply. Although modern water heaters are often equipped with automatic, periodically, when heated, a sharp pressure jump occurs, which can lead to disruption of tightness of the container. To avoid jumps, a safety valve is installed on the cold water inlet nozzle. When the threshold value is exceeded, the faucet opens and some part of the water, aligning pressure. Therefore, when installing a crane, make sure that the drain output (small socket) is directed down. If you want your boiler to work for a long time, put this valve necessarily.

It is convenient if it has a second function - it works as a check valve, overlapping the outflow of water in the absence of pressure in the system.
Safety valve for boiler
If you look at the photo, there is an arrow on the housing that shows the direction of water movement. If such an arrow is, the device works and as a check valve, not allowing water to be poured. If there are no arrows, it will also have to install the check valve (above the safety).
What functions the safety valve performs, and how it is better to install it if it is not over the bathroom, look in the video.
Another mandatory detail of the scheme is shut-off cranes. They are usually put on the branch from the riser of hot and cold water. These cranes are required. Sometimes they are set before a security group, but they are no longer obligatory, but serve only for more convenient repairs.
A security group is a coarse cleaning filter and pressure reducer. If these devices are not at the entrance to the house or apartment, it is very desirable to put them: they extend the life of the water heater.

Connecting a boiler to electricity
All water heater manufacturers recommend include boilers to electricity to a separate line from the electrical tailor, on which a double automatic and Uzo is installed, note that the machine must be double - that is, such that bursts simultaneously and the phase and zero. There is also necessarily grounding. These measures ensure safety, so you should not neglect them.

Instead of the bundle of the UZO + automatic, you can put the DIFAVTMAT. It will also control the leakage current and short circuit, but is performed in one case. On the middle power boiler, there is enough automaton by 16 A, and the current leakage current is 10 mA. The cross section of the copper wire (monashed) is enough 2.5 mm.
How to install a flow water heater
As already spoke, the flowing water heater has smaller dimensions, because the place for it is easier to find. It can be hung nearby on the wall, and you can-cut into the locker. Its dimensions are usually 15 * 20 cm * 7 cm or so. In general, small. Weight - from strength 3-4 kg, so that the requirements are minimal to fastener. Usually or placed on two small diameter dowels screwed into the wall, or has a mounting plate that is screwed to the wall, and the water heater is already hung. How to install a flow-type water heater figured out, now about connecting.Article on the topic: Girl grapes on the balcony: Growing technology (photo)
Connecting a flow water heater to the water supply
From this side everything is simple. But the disadvantage is that at the same time supplied with water, it can only one point. Depending on the place of installation on the outlet of warm water, they put a shower can with a flexible hose, or a hussak - for washing dishes. There is an opportunity through the tee to put both "hussak" and a watering can (how to extremely right on the right).
How to connect flowing electric water heater
To have the opportunity, if necessary, remove the water heater and do not overlap water in the entire apartment or house, at the entrance and at the output are ball valves. They relate to mandatory equipment. Connecting from nozzles until the twinkle in the cold water supply line is also carried out in the same way as when the boiler is connected: corrugated stainless steel hoses or plastic pipes. Hot water to the point, if necessary, is conducted by a flexible hose: there are no temperatures too high in principle, so it should withstand.

Another feature of flowing water heaters is that they can normally heat only a certain amount of water. With increasing flow or too low temperature at the input, they are coping with the task. Because most often this water heater is used as temporary - in the country or when the hot water is disconnected for prevention (for summer).
It is easy to resolve the issue with excessive amount of water (with an increase in pressure above the normative) is easy: or put the gearbox at the inlet or flow limiter. Reducer - a more serious device and recommended to put at the entrance to the apartment, and the flow limiter is a small cylinder with the valve. It is checked on the inlet nozzle of cold water. An example of how to install a flow-up water heater and where to turn the flow limiter to the video.
Connecting to electricity
With the electrical connection, everything is as well as with a boiler: a dedicated line, RCD + automatic. Others only the nominations and cross-section of the wires. The denomination with power up to 5 kW - 25 A, up to 7 kW - 32 A, from 7 to 9 kW - 40 A. Section of the Copper Wire Zhida - 4-6 mm (Monastened).
