The absence or frequent shutdown of hot water makes you think about buying a heating tank. Such a device is used to heat water, which is under pressure above atmospheric. The equipment is very valuable and irreplaceable both in multi-storey buildings and in the private sector.

When the decision is made, you need to connect the boiler to the water supply. At the initial stage, you need to carry out:

1. The choice of the device according to the volume, level of automation, equipment and appearance.
2. Boiler installation.
3. Connecting the water heater to the water supply.

Common types of heating tank

Flow-through boilers are distinguished, in them a stream of water moves through an electric heater, as well as storage ones, when water is heated in a container and is used as it is consumed. Therefore, you need to think rationally - a 30-liter tank will be enough for a family with 3 people, but for 5-6 people it will be reasonable to purchase a 50 or 80-liter boiler.

We also pay attention to the design of the equipment, choose the color, style, dimensions according to the bathroom interior. An important element is the way of fastening the unit, horizontal or vertical, so that the tank does not take up much space and fits ergonomically into the general space of the bathroom.

Installation

Before hanging the device, it is important to read the manufacturer's instructions. And also make special hooks on the wall and hang the case firmly and evenly on a previously prepared surface.

Connecting the unit to the water supply

The diagram for connecting the boiler to the water supply is very simple, the unit is connected in parallel to the water supply system. Now you need to distribute the required number of pipes for the water supply. Plastic ones are fastened with soldering irons, and steel ones need to be welded with a construction tool.

Attention: in order to prolong the life of the heating element, it is advised to install a cleaning filter on the water coming from the scale. Thus, less limescale deposits will accumulate, and therefore the boiler will serve for a long time and without interruption!

How to connect a water heater to a polypropylene water supply system? If the pipes are not hidden in the wall, then it is very easy to connect the tank to the water supply system, you need to cut the cold and hot water pipe in the designated place, solder tees into the holes, from which to draw the pipeline to the boiler, connect to the taps with a coupling.

With a pipeline closed into the wall, connecting the water heater is a little more complicated. It is necessary to open the pipes, perform a tie-in, remove the pipes and close everything back. Together with tees, it is important to use split couplings, because to solder non-expanding pipes not

possible. When the welded joints are solidified, the connectors are connected and the connection of the water heater to the water supply is carried out according to the previous scheme.

How to connect a boiler to a water supply system with metal-plastic pipes? Fortunately, it is not carried out by a hidden method, and therefore the scheme for supplying water to the tank does not cause much trouble. The pipes are cut and tees are inserted, after which they are fed to the heating device. It is done!

But to connect an electric water heater to a water supply system with steel pipes is the most difficult procedure, which involves bringing the boiler through the nozzles of the mixer for washing in the kitchen. A tee is put on each of them, which allows you to bring both a kitchen mixer and a boiler to one pipe without cutting a thread.

Attention! When installing the water heater to the water supply, it is prohibited:

• Open the protective window when the device is turned on.
• Check the functionality of the unit without water.
• Drain water when power is on.
• Mount parts from other devices and devices.

Professional advice

The boiler system for hot water supply, in addition to the shut-off valve, which is located on the branch pipe of the tank that supplies hot water, does not require additional elements. But when connecting a pipe with cold water, you first need to put a tee, on the side outlet of which a tap is installed to drain water from the tank. Then install a check valve on the tee, after which a shut-off valve is also installed, which is connected to the inset with the water supply.

The importance of the safety valve

This unit prevents the movement of backflow of water into the plumbing system, normalizes pressure surges and releases excess water when heated.

Installation of a non-return valve instead of a safety valve is not permissible

This can lead to an explosion in the room if the temperature switch of the water heater fails.

The valve is located at the cold water inlet to the heater. It is forbidden to place shut-off devices between the valve and the boiler inlet. The efficient operation of the heating tank is directly dependent on this brass device.

If the valve occasionally digs in, this is considered normal and means that it is working correctly and protects the tank from bursting. However, if the pressure in the line rises above 4 atmospheres, then permanent operation is possible, we recommend installing a reducing pressure reducer.

When the valve is dry for a long time, it means that it needs to be checked; it may have become unusable and needs to be replaced.

Connecting the boiler to the network

To supply power to the heating tank, it is necessary to run a separate cable from the distribution panel of the apartment with a copper conductor section of at least 2.5 mm, and the shield itself must be equipped with an RCD residual current device. It will help protect the inhabitants of the premises from electric shock in the event of an electricity leak to the boiler body.

The water heater must be grounded, and the outlet must be chosen moisture resistant, especially if it is installed in a bathroom.
