Water heaters: wiring diagram. Connecting the water heater to the water supply system:

Electric water heaters have recently become very popular among the population, since they give autonomy from the central supply and allow creating comfortable conditions where there are no boiler houses. However, when purchasing such products, users often have questions about their installation. That is why, when acquiring water heaters, the connection scheme of which assumes a separate inset in the water supply system, it is worthwhile to learn in advance about the actual installation process.

Operating principle

Such units operate due to the active resistance of the fans, inverters or anodes, which are installed inside the tank. When water enters it, they produce heat and maintain the temperature at a certain level. As a result, the user has access to this benefit of civilization at any time.

Models and their connection systems

At once it is worth noting the fact that the connection scheme of the Ariston water heater is practically no different from the same projects of other manufacturers. Therefore, to consider individual models simply does not make sense. All of them are almost of the same type and do not differ from each other in any way.

However, there is one kind of this device, which has special design features, affecting the installation. The point is that the connection diagram of the instantaneous water heater does not imply full integration into the system. Typically, such products are separate units that have their own water supply and output directly from their own capacity.

Electricity and water supply

First of all, it is necessary to remember that the manufacturer gives a guarantee on his water heaters. The connection scheme should be used exactly the same as planned in the project even while developing the device. However, most experts recommend to leave a standard connection for integration into the water pipe, but they are suitable for the electrical part separately.

Given this, it is necessary to separately describe both the process of the electrical circuit and the connection to the water supply system. At the same time, the installation should be stated in detail, proceeding from the fact that the project is designed to fit into an already existing network.

Materials

• First of all, you will need pipes that will connect the system and water heaters. The connection scheme when using the tie-in involves the use of metal-plastic products. They are more reliable and do not require additional tools for installation.
• Next, you need to purchase accessories that will be used to connect all the elements. In this case, separate attention should be paid to the fact that you need two tees, which will carry out the transition from one tube to another.
• It is also advisable to purchase a pair of valves that block water access to the heater. Basically they are not needed, but in some situations it is very convenient to be able to physically close access to the device.
• A typical electrical connection scheme for a water heater assumes the availability of a cable corresponding to the capacity of the unit. It is desirable that it be made of copper and have a good protective shell.
• Separate attention deserves a protective device or machine. It is also selected based on the power of the heater. It is thanks to him that it is possible to make a complete shutdown of the device, which is not provided for in some models, and it will also provide protection for the product itself and the entire network.

Tool

The set of necessary tools directly depends on the materials that will be used in the work. However, if the connection scheme of the water heater involves the use of metal-plastic pipes, its quantity can be greatly reduced.

• First of all, you will need a set of keys that will be used when clamping the connections. Therefore, it is necessary to worry in advance about the fact that there is exactly the instrument that will correspond to the fittings.
• Also, a special cutting knife is needed. If necessary, it can be replaced with a hacksaw, but it will be necessary to clean the edges of the cut.
• For some works you will need a screwdriver, which is useful not only for fixing certain couplings, but it is just necessary when connecting electrical circuits.
• Special attention should be paid to the perforator. This tool will be needed to fix the heater itself to the wall and fix the pipes that will be fed to it.
• Usually connecting a water heater to a water pipe, the scheme of which involves the installation of its own power cable, does not involve the use of pliers, knives and insulation tape, but it is advisable to have these things at hand.

Hardware Fasteners

It should be noted right away that there are many models of these products and each of them assumes its own way of installation. For example, the connection diagram of the water heater "Termix" directly depends on the specific features of the selected unit. It can be suspended from the ceiling, wall and even installed on the floor. Functionally, this arrangement does not particularly affect the circuit itself, but the wiring and fastening depend on it.

In order to properly fix the heater in the plane, first you need to measure the horizontal with the help of a water level so that the product does not have any distortions. You also need to measure the vertical with a plumb bob. Next, on the plane, places are marked for mounting the fasteners, which are mounted with a perforator. After that, the heater can be hung in its place.

Water pipes

At this stage, it is necessary to create a closed pipeline, part of which will be water heaters. The connection scheme here usually involves inserting into the existing system. However, there are exceptions, but in this case a separate project is being prepared for the entire wiring.

• First of all, it is necessary to cut the cold and hot water pipes in accordance with the clamps or adapters used. Usually for this purpose the water pipe is cut and the tee is inserted into this place, but in some cases it is possible to simply drill a hole and use a special clamp with a clamp and a tap.
• Next, tap water is installed on the water outlets on the heater. Some masters consider this not mandatory, but it is with their help that you can make a complete dehumidification of the product or completely cut it off from the system.
• At the final stage, you need to connect the cold water pipe to the corresponding tap on the heater, and the same is done with the hot system. They are usually marked in red and blue.
• It is also worthwhile to divert from the safety valve of the device with a special hose, which is usually placed in the toilet bowl or drain.

Electricity

Usually the connection diagram of the water heater is pretty simple. Many people think that it is enough to simply bring the outlet to the product, into which the plug of the unit wire should be inserted. However, experts have their own opinion on this matter.

Professionals first prefer to completely cut the plug and make a connection to the machine. This reduces the number of contacts and reduces the factor of a substandard outlet. Then lead the wire to the junction box. It is opened and connected directly to the wires of the supply of this section of the apartment or building.

Recommendations of specialists

• Before you start working on the sidebar in the pipe system, you need to turn off the water. The same applies to the installation of an electrical circuit.
• Typically, the connection of a water heater to a water pipe, the scheme of which involves the use of several units, is carried out independently of each other. So you can ensure the stable operation of both devices and get the opportunity to disable one of them.
• Choose a similar product is necessary, focusing not only on the type of premises where it will be installed, but also on the number of future users. This factor should be the main one, since the level of comfort depends on it, for which reason the heater is installed.
• Some models of such products have their own installation and connection features, which are individual. They are usually described in detail in the instructions that come with the kit. Compliance with these conditions is strictly necessary, since the functioning of the specific model and the period of its operation depend on it.
• In some stores, you can purchase special sets that are designed to connect to the water supply of certain models of heaters. They are quite practical and save a lot of time and money. However, it is necessary to be very careful to choose the product that is suitable for the already existing water supply network. Therefore, first of all, it is necessary to pay attention to adapters and coupling sleeves.

Conclusion

Based on the above, it can be understood that the connection diagram of the storage water heater is exactly the same as that of any other device of this type. At the same time, even a novice specialist can cope with its development and implementation, having a minimum of tools and even not having much experience. However, it is necessary to remember that some manufacturers give a guarantee on their products only in case of correct installation without breaking the seals of the cover of contacts or when using the services of specialists with appropriate qualifications. Therefore, this issue needs to be clarified at the acquisition stage.
