A household appliance for heating water is installed in an apartment, a country house or a private dacha. The selection and installation of a water heater is related to the number of people living in the room.
Although the installation process itself is simple, but without experience it is problematic to install with high quality. Therefore, it is better to read the instructions, read the tips and tricks.
Generalized work plan for connecting a water heater
Standard actions:
- Choose the most suitable place in terms of size and location. It is necessary to measure all planes with a margin for the water heater.
- Find out the exact number of water intake outlets. This includes bathrooms, sinks, showers, etc. The power and complexity of the connection process depend on the number of points.
- Wiring information. It is better to know the cable cross-section, its maximum loads. The fact is that neglect of electricity in the house can lead to accidents. For more confidence, invite an electrician for a consultation and find out exactly how to connect the water heater, whether it is possible to connect a heater of the declared power. If the specialist says that the voltage is weak, then you need to “throw” a new cable individually.
- The quality of the supplied fluid. Water entering the boiler tanks should ideally be filtered. If the water quality is low, it is better to install primitive filter elements in the system to save the working surfaces of the heater.
- Find out exactly for yourself which heater is better: with a storage system or a flow one. Moreover, the size and manufacturer will also play a role.
- You will have to choose not only between models, the type of device will also make you think about the choice. You need to decide between wall, floor, vertical or horizontal type.
- The device should be fixed as firmly as possible to the surface. It is correct if it does not move when touched, and its movement in different directions is strictly prohibited by safety regulations.
- The water heating system must be completely sealed.
- It is not recommended to use poor quality hoses for piping. The optimal material for such elements is steel, copper, metal-plastic or plastic.
- The first start and further use is strictly in the presence of liquid in the riser or water supply.
How to install an electric storage heater
For those who decide to do this work on their own advice! Under no circumstances should a vertical device be installed in a horizontal position and vice versa!
Connecting a storage water heater is more convenient and most correct to do as follows:
- Preliminary assessment of the place for installation.
- A room with a small area, as a rule, does not have a large space for household appliances. Connecting the water heater to the water supply in the apartment, in this case, is performed in hidden niches or plumbing cabinets.
- Equipment with a volume of up to 200 liters can be mounted. Strictly on the floor, devices with a large volume are installed, otherwise a break is inevitable.
- A water heater from 50 to 100 liters is best fixed to a load-bearing wall. Use an anchor bolt for fastening. Such fasteners must be purchased additionally, because they are not included in the kit. In no case can you save on an expensive device. The more brackets for the heater are fixed, the more reliable the operation process from year to year. For hinged models of 100 liters or more, there must be at least 4 brackets.
- If you decide to put the device in a hard-to-reach place, then consider maintenance in advance. A poor quality model will often have to be repaired, and this is not comfortable to do in hard-to-reach places.
A safety valve must be installed. It will save the system from mechanical damage and excessive pressure. The principle of operation is simple - excess water is removed at elevated pressure. In other words, the water is discharged to the operating pressure of the system.
How to turn on an already installed heater
So there is a need to use . You need to do the following:
- Shut off the hot water valve installed on the riser. If this is not done, then the water treated by the device will enter the general water supply system. When closing the valve, a specific sound will be heard, confirming the blockage.
- Next, open the valves to the water heater. The first one goes with cold water, then open the tap that supplies water from the boiler to the drains.
- After these manipulations, turn on the device in the network. Popular models of boilers and water heaters will automatically start their work with the correct water supply.
Sequence on the diagram:
Doubtful actions or opening taps not according to the instructions are best not to perform if you are not sure or if you are encountering a household appliance for the first time. Sometimes it is cheaper to call the master even to turn on 3 taps and start the device than to pay for repairs after leaks.
How to connect a storage water heater in the country
The installation of heating elements in the country implies a low-pressure water supply system in the system. Unfortunately, without a pressure of several atmospheres, it is impossible to connect and operate a storage water heater using the classical method. There is a working approach for such a situation.
Boiler tanks are filled with water thanks to the tank, which is already installed separately from the water heater. The use of a check valve in such a circuit is not possible. 
Additional capacity is selected by volume. It should be several times the volume of the heater tank or tanks. The pressure vessel must not be closed (vacuum). In other words, you need to drill holes in it.
It is more practical to provide such a tank or container with a float valve to regulate the water level.
The connection from the tank to must be equipped with a tap or valve.
A tank that creates pressure is most often installed in the attic. The main condition for the operation of the system with an additional tank is the location of the pressure tank above 2 meters from the boiler.
When installing a water heating element in a country house or in a house for periodic residence, it will be necessary to drain the liquids from the tanks before the onset of cold weather!
Any water heater is demanding on the conductivity of the electrical network. We are talking about the cross section of the cable, namely the copper core of the wire. Its thickness should start from 2.5 millimeters.
A good connection to the network is not possible without a fuse or protective device. Any heater model must be equipped with an RCD (residual current device).
The classic way to connect to the network is to plug into the nearest outlet. It is important to establish grounding. To do this, use a three-pole socket with a moisture-resistant function.
The classic method is suitable for water heaters with low power. Powerful models are not designed for this method. They will at least heat the outlet.
Systematic heating of the socket will lead to weakening of the contacts and the appearance of a spark. From the spark, the plastic of the socket will ignite, the heating element will break, and the power supply system will ignite.
It is better to take care of security in advance. To do this, you need to bring the electric cable of the desired section individually. In this case, a wire is mounted from the electrical panel to the boiler without additional sockets or branches.
Without plugs and sockets, disconnection is only possible via an automation device. Although the main function of the machine is the safety and safe use of the water heater.
If there is no fuse in the kit, then you need to purchase a device with a calculated sensitivity level. If you install a fuse with low sensitivity, then a permanent unreasonable shutdown of the boiler cannot be avoided.
For powerful water heaters, 16 amp fuses are installed.
In the process of acquiring the desired water heater, it is better to decide in advance how further installation will take place. When installing with your own hands, in no case should you ignore safety precautions. At the slightest doubt, it is better not to save money, but to call experienced specialists.
