When it comes to relative comfort to somehow survive a few weeks, an ideal solution can be the installation of a flow water heater. The most basic advantage is ease of installation. Absolutely any person can cope with this process, which has exceptionally general knowledge of plumbing and wiring.
Most often, such heating devices hang on the wall, as close as possible to the mixer in the kitchen or in the bathroom, so that it is possible to maximize the heat loss. Flowing heaters, compared to cumulative, have a rather small weight, in connection with which the particularly durable attachment does not require. Ordinary brackets and fastening screws may well come. Flowing heating devices are located both over washing or sink and under it. For both cases, the connection scheme must be specified in the instruction that comes with the device itself.
The advantages and disadvantages of this design, the installation of which is the ability to perform yourself

Advantages of the running water heating device:
- Quite small sizes compared to cumulative water heaters.
- More simple installation process.
- The lowest possible device.
Disadvantages of flowing water heater:
- The high energy consumption is quite high - from 5 to 30 kilowatt (most often from 5 to 8 kilowatt, but in some cases it can come up to 30).
- The need for high water pressure in the system, otherwise there is a possibility that the device is burning.
- In connection with the previous problem, it is impossible to use a similar device on the upper floors of multi-storey residential buildings.
If a small family lives low and the apartment has no room to install a cumulative heater, the choice of the host should be made in favor of flowing water heaters.
Installation of flowing water heaters with your own hands: Tools
It is worth paying special attention if any moments on the installation of a flow water heater will be incomprehensible, should not be attempting to independently perform the installation of the electric heater in order to avoid electric shock.
Installation and further operation must be carried out in compliance with safety.

It should be noted that the flow heater at the exit should necessarily be a shower or ordinary, otherwise it will not have time to heat the water.
What will be necessary in order to perform the installation of a flow water heater:
- Flow-type water heater.
- The hose from the shower, which must be connected to the mixer to the disconnected shower nozzle.
- An electric drill that can drill in a hole in the concrete.
- Screws and dowels.
- Drill for concrete under the size of the dowels.
- Triple copper single-core electrically conductive, which has a sufficient section for the heater power.
- Watering key.
- Screwdriver either screwdriver.
- Passatia.
- Fumilent.
In case it is planned to install inpatient:
- Tee in order to divert water to a boiler from a plumbing system.
- Crane valve, which overlaps water at the inlet of the device.
- Flexible hose-wiring of the required length from the water supply to the heater.
It is possible to do and a set for the installation of metal-plastic pipes (cutting pipes of the corresponding length and collet connectors-clamps).
Preparation of a flow electric heater
Scheme of the protocate electrical heater.
First of all, you need to choose the required flowing water heater. There is a sufficiently large number of devices of this type that can be installed with your own hands. They are quite different in design and form. However, they are all arranged within approximately the same, and the installation of them is always the same.
The design of the flow water heater is shown next image 1, where 1 is the heating element, 2 - switch, 3 - terminals of power connections, 4 - rotary compressor, 5 - connection to the water supply, 6 - output of heated water, 7 - holes required to attach the device to Wall.
Any flow water heater will consist of directly the heating element (which is searched from all sides of the cylinder and from which 2 cuts of 1/2 inches threads are conducted, 3 terminals to connect the carrier, zero and ground wires), switch or switch and enclosures.
The heater to be installed, depending on the model, can be equipped with a stepped and smooth recovery regulator of heating, safety sensor from disconnecting or overheating water, light indicator.
It should be stated on the wall of the place where the flow water heater is planned to be fixed. They will be needed for drilling holes. Next, you need to do the appropriate number of holes, after which you drive the dowels in them. Next, you can begin to perform the installation of a flow water heater.
Mounting a flow water heater with your own hands

Installing and connecting such an instrument can occur in 2 ways:
- With the help of a shower hose to turn off it as soon as they give hot water. In this case, switching between the water heater and the mixer crane will be carried out using the mixer handle. When the handle is in the position for the shower, water will be able to go from the water heater, and in another position - as usual, from the crane.
- Inpatient in the apartment system of the water pipeline. In this case, it is necessary to install a separate valve at the entrance to the water heater. It makes sense to consider in more detail this method.

It is necessary to overlap cold water, after which it is necessary to install a tap adapter using fumes in the intended place.
Installing the drive occurs according to the instructions for connecting heating wiring. Another end connects the wire, for example, with a socket for a washing machine. Heating power consumed in no case should exceed the possibilities of wiring in the existing apartment. Otherwise, in the process of incorporating the water heater at full power, it will be the likelihood that sees the plugs or automata.
Next, you need to fasten the water heater to the wall into the holes with the dowels that were prepared in advance. Now you need to turn on the water heater into the plumbing system.
The valve joins the input pipe of the device, and the flexible hose or the metal-ceramic tube joins the valve. Everything will depend on the installation of which system is planned. Pipes or hose must be connected to a specially prepared adapter. At this stage, the system will be ready for operation.

Next occurs the installation of the crane or a shower mixer from the configuration of the water heater. After that, you can move to the test of the installed device. It is necessary to include the unscrewed pressure of the water and the power supply of the heater. Approximately 10-15 seconds from the crane can be warm or if the installation was performed a sufficiently powerful device, hot water. Its pressure and warmth can be adjusted by using the valve: when the water is strengthened, it can be cool. It should be said that in the device for 3.5 kW hot water (boiling water) is absolutely impossible to get. The temperature at different water heads will be from a little warm to almost hot. The device that has a lower power is advisable to purchase exclusively in case the apartment is an old wiring that does not withstand even 3.5 kW.
If the flowing water heater is located in removal from the sink, the mixer must be connected using the use of a flexible hose and fix on an additional bracket in a sink, in which an additional crane-hussak cannot deliver inconvenience.
Installation of flowing water heaters: Recommendations
If everything satisfies with the connection and there is a desire, you can hide communications behind the walls panel. Now it will be possible to enjoy the warm shower all year round and not be afraid of turning off hot water.
If there is a water of not very good quality in the house, it makes sense to connect the heater with a water purification filter: it will give the opportunity to extend its service life and improve the purity of water at the outlet. The most reliable option for connecting a high-power water heater is the installation using a cable with a cross section from 2.5 mm, which is able to withstand a load of up to 10 kW with a current of up to 40 A.

Do not include the water heater without water supply. It can bring it out of order. Be sure to use grounding during connection to the network. It will also be necessary to use the automatic fuse, which is triggered at a current at least 32 A.
It should be remembered that the incorrect installation of flowing heating devices can lead to a breakdown of the device itself and, therefore, loss of warranty repair.
Water heater connects to the water supply in the diagram, which is specified in the instruction. Depending on the model, the installation can be performed using the use of flexible or rigid wiring. All connections will be required to be sealed with FMU and sealant tape. In order to perform control, you should open a tap with water and check the reliability of the connections after the installation is completed.
If the flowing water heater is combined with a crane or a shower nozzle, you will need to connect it to cold water. However, if an ordinary linear heater was purchased, it must be connected to hot and cold water pipes. In order for such a water heating device to work with the correct compliance with the temperature mode, it will take to make the water temperature that goes does not exceed 35 ° C.
Shut-off valves and sanitary liner must necessarily comply with all the parameters of the water supply network and water heater. Location of nozzles, their horizontal or vertical orientation must comply with the recommendations from manufacturers.
The last thing to be noted is: the flowing water heater will not warm the water to a certain temperature. He only heats it, for example, at 20 ° C. Thus, in the winter and summer period, the water temperature after its heating can be different: from warm in winter to hot in summer.
Connection of electricity to flow heater
Flowing electric water heater must be included in the network after performing all installation work, as well as after the heater is filled with water. If a household flow unit was purchased, which has low power, then connect it is the ability to the outlet.
Before purchasing an electric flowing water heater, you should carefully calculate the load on the electrical network and prepare a three-phase separate connection for 380 volts in advance. The cable type must be selected based on the declared power of the heating element (TEN). A similar device for heating water is the ability to be considered electrical exclusively with an effective grounding.
In addition to avoiding the damage to the equipment, you will need to install a protective shutdown device (UZO), which provides emergency disabling design. According to the safety requirements, you will need to connect a differential machine with the characteristics that correspond to the load on the network.
