Problems with hot water supply of residential premises are found everywhere. In the summer period, hot water is turned off by utility services, motivating it with the need to repair the entire system. In another period of the year, the same problems are less frequent, but they can not be completely insured from them. The only way out is to have a local system that allows water to be heated. Excellent proved in this regard boilers. Consider how to install a storage water heater and its flowing version.
The device of a running water heater.
They differ in both the capacity and the volume of water that is placed in the tank. Such a water heater belongs to the family of storage devices and does not have any subtleties in the design and operation. The boiler arrangement is remotely similar to an ordinary electric kettle. This is the same capacity for water, inside which there is a heating element (TEN).
Stages of installation
The capacity of the boiler is determined by the total capacity of the heating elements, which are installed in it. The boiler design includes sensors for temperature, pressure, water level and thermostat. At its core, any boiler is a running water heater, as water enters it, heats up and leaves the tank. The boiler is supplied with an instruction that describes in detail how to properly install a storage water heater (boiler). This whole process (regardless of the device model) consists of the following stages:
Scheme of using a running water heater: during operation of the water heater it is necessary: crane - "2" close, taps - "1", "3", "4" open; when the water heater is not in use: the cranes - "3", "4" close, the cranes - "1", "2" open.
- installation of the device and all its components;
- connection of water to the boiler;
- organization of hot water discharge (connection to cranes);
- connection of the water heater to the electrical network;
- grounding of the device and control tests.
Installing a storage water heater is simpler than a flow analog that does not have a capacity.
The storage water heater does not have any special requirements other than those required for water hardness and timely preventive cleaning of water heating elements. The order of service and its frequency are strictly regulated by the attached instruction.
Install a running water heater that does not have a storage capacity, is also easy, since it is devoid of complex elements.
Typically, such a water heater consists of a housing, inside which there is a heating element, a water pump and a temperature sensor. In the outer part of the case there are two nipples and three terminals (and several regulators, the number of which depends on the model).
Beginning of work
First you need to read the assembly instructions and choose the most convenient place for installing the water heater on the wall. The choice of the place where you will install the water heater must be coordinated rationally with the location of the water pipes. Do not connect the device through various tees. The temperature of the heated water depends more on the speed of the water inside the water heater. When connecting such a device to water in parallel to other devices or cranes, the speed of water will change constantly. This is not very convenient, as water will constantly change temperature.
Tools and materials

Also it is desirable to connect the water heater to the power grid through a separate line. It is not recommended to use the connection to a common network via a standard outlet, since the device is characterized by too high power consumption, not any wiring in the house can withstand such a high load.
If there is no possibility to connect a water heater to a separate line, then an experienced electrician should be consulted. Without measuring the section of the wiring and its insulation, you can not do. And if all measurements are made and you have received permission to connect, then you need to stock up the following set of tools and materials:
- a drill and a set of drills;
- dowels and screws;
- a set of keys;
- FSM tape;
- metal-plastic pipe and its corresponding tee and crane;
- electrical wiring and electrical tape.
The order of work
On the supporting wall we have a water heater (above the person's head) and mark on it the attachment points. The height of the water heater should be such that the water can quickly leave the device. Otherwise, the heating element will overheat very quickly and fail.
So, you have determined the place where you will install the device, and made the necessary marks on the wall. Further all is simple: we drill apertures, we hammer in them djubeli, we put a water heater and tightly we screw screws.
Connection to water
Installation of a running water heater.
In the water distributor clamp the metal-plastic pipe and with the help of the holders we bring it to the inlet pipe of the water heater. The connection of the pipe to the branch pipe is made by means of an adapter, which must be supplied with the device. The threaded joint is sealed with a PCM tape.
To the outlet branch pipe, we connect the tap in the same way. It is desirable, that water was taken away only on one line, therefore it would not be necessary to mount various adapters.
Install cranes and diffusers having narrow holes with a water heater. Conventional devices can also be connected, but in this case the water will quickly pass through the water heater, so it can not get warm enough. It is necessary to understand the adjustments for a long time, but it will be very difficult to achieve the desired water temperature. If a special diffuser is not included in the delivery of the water heater, you should consult with the seller regarding the choice of the appropriate parts for the most reliable equipment.
Importance of grounding
Connecting a flow-through water heater.
It must be remembered that the water heater is electric, so it needs grounding. You should not rely on the grounding, which is provided by the outlet of the device. No wonder the water heater housing has a special terminal for grounding. Doing an installation without proper grounding means putting yourself and your loved ones at risk.
Maintenance of the flowing water heater is done with very dense periodicity. The heating element is very sensitive to the quality of water, so all impurities will inevitably cover the TEN with lime coating or rust. Cleaning the heater is necessary with an approximate regularity once every two weeks (with regular use of the water heater).
The second point, which concerns the length of the life of the water heater, is to turn the device on and off correctly. Statistics show that in 70% of cases the device breaks down precisely because of violation of the rules of operation. The correct order of the heater switching on is as follows: turn on the water, turn on the heating element after 10-15 seconds. When turning off, the order should be reversed. Violation of this rule leads to the fact that the heater of the device is not cooled by the flow of water, so it quickly burns out.

Manufacturers of flow-through water heaters understand that most users will connect the devices to a common electrical network via a socket.
To avoid unpleasant consequences, most flow-through water heaters go on sale without wiring. To consider such devices as substandard does not follow: rather, this indicates a high quality of the product.
And still need to say a few words about the wiring. Previously, for the installation of electrical circuits in the apartment used wiring, which in its parameters in dozens of times exceeded the total power of all electrical appliances.
At the present time, the number of devices in the apartment has increased. The old wiring simply does not withstand such loads. This is another reason to think about the fact that the water heater should be connected in parallel with the main network in the apartment.
Take care of the availability of reliable machines for the meter. Regular semi-automatic plugs for 10 A are no longer suitable.
It is not necessary to perform the whole cycle of works on electric supply of a water heater independently: entrust this work to an experienced electrician.
