Water heaters are an essential household appliance that helps to make life much easier. We propose to consider how the water heater is correctly connected to the mains, to the water supply, in the country, as well as the installation of a horizontal boiler in the country and in the apartment and the general installation scheme.
Detailed connection and construction description
In this way, you can connect a storage water heater from Atmor (Atmor), Elenberg, Eltron, Etalon, Ferroli, Gorenje, Polaris, Stiebel, Thermex, Vega, Termeks, Ariston (Ariston), and others. It is considered the most effective option for connecting a simple vertical boiler, but first you need to understand the design of the device.
A standard boiler consists of the following parts:
- element that heats water - heating element;
- a tank that keeps the water temperature at the right level;
- thermostat;
- water drainage and supply systems.
The most important thing when choosing a boiler is the way it is attached to the wall (vertical or horizontal), and the volume of the tank. Most often, vertical appliances are used in modern apartments: they take up much less space than horizontal water heaters and are connected to the water supply system much easier and faster.
Step-by-step instruction:
A fuse or safety valve is a special device that serves to protect the tank from rupture at very high temperature or pressure. This can happen if the liquid pressure in the tank exceeds the nominal value (the standard value is 0.6 MPa). The pressure valve hole must be open without fail, because often home specialists simply forget to ensure that excess hot water is drained into the sewer in time, which puts themselves and their families in serious danger.
It must be said that the standard valve in a set with a water heater most often simply does not cope with its task, and we recommend that you immediately buy a protective device separately, having already foreseen the needs and capabilities of the boiler.
- The valve consists of a whole system of parts, including a plumbing tee, the valve itself, an American coupling, a reverse-acting valve (which prevents hot and cold water from mixing, which means it saves energy and reduces pressure on the internal tank of the boiler);
- Now, with the help of pipes and compression hoses, we divert water into the sewer. If necessary, simple garden hoses can be used, although they are not designed for use in hot water conditions;
- We seal the connection with a special sealant, leave it to dry for 4-8 hours. We turn off the water long before the start of the process, even a slightly damp pipe will not be airtight and will quickly “disperse”;
- Next, we continue to connect the boiler to the water supply system.
- We advise you to give preference to pipes made of polypropylene materials, they have a much longer service life and are easier to install than metal pipes. We connect them by welding polypropylene, leave to dry a little. Some masters carry out this operation, having only metal-plastic pipes, but they are much more difficult to install and less reliable;
- Then, using a ball valve, we bring cold water to our boiler, connect, check and, if necessary, fix with a sealant the junction of the water supply hose and the inlet hole;
- We also drain hot water through the same ball valve, this also provides for the connection of a storage water heater and a flow one;
- It is necessary to make the system in such a way that when the taps are closed, water does not flow, but if the riser valve is closed, liquid can be used;
- Now, depending on whether we are connecting an electric water heater or a gas water heater, we need to connect the device to the power system and check its operation. When using the first method, all the requirements of the PUE are taken into account: waterproof sockets (especially in the bathroom), grounding of a household appliance, most likely, you will also need a separate RCD for a two-phase boiler, etc.;
- Check the condition of the cable, it must be moisture resistant, durable and elastic.
Installing an outdoor boiler
Installation of a floor or horizontal boiler does not take much time, but it is a very voluminous job. They are often more than 50 kW, and they weigh about a hundred kilograms, so they are difficult to transport or simply move on their own. The system is connected to hot and cold water in the same way as a vertical water heater, with the difference that the drain hole is at the top.

The grounding system is also more serious; a separate outlet is provided for powerful boilers. It can be easily done with your own hands, just branch off the wire from the iron part of the device, and connect it to an independent output to the ground.
This device is mainly used in production, because. it has a fairly large volume, and the price is high - from 80,000 rubles (the cost was taken into account by the regions of Yekaterinburg and Moscow).
As you can see, connecting an instantaneous water heater is a simple task that requires maximum concentration. If the coupling is connected incorrectly or loosely tightened, then failure is inevitable, because of this, the service life can also be significantly reduced.
No special documents are needed if you buy a water heater, not a gas water heater.
