How to install a instantaneous water heater?

Water heaters, or boilers, are becoming more and more popular in the home appliance market, because the state of hot water supply, to put it mildly, leaves much to be desired. Many are not satisfied with the tariffs; one does not have to talk about the quality of the service at all. And summer blackouts have become almost the norm. An excellent temporary option in this case is a flow-type boiler. In this article, we will figure out how to install a instantaneous water heater.

Features

The main difference between a flowing boiler and a storage boiler is that it produces heating of running water. After the tap is open, cold water enters the device, heats up and comes out already hot. In fact, the principle of operation of a hot-water device resembles a familiar column, only it functions not from gas, but from electricity.

An important advantage of the flow-type device is its compact size. If the storage boiler produces heating for a certain time and provides the apartment owners with water within the tank volume, then the small appliance heats the water almost instantly. In addition, it is very easy to mount.

Important! Their only drawback is the installation of only 1 conclusion: a kitchen sink or shower. It is impossible to install one flowing device so that it provides the whole apartment with heated water. An improvement made in this regard is the combination of a boiler with a shower and a washbasin faucet.

DIY instantaneous water heater connection - installation algorithm

Despite the fact that the instructions indicate the installation and connection of the device, we will dwell on some points in more detail.

How to choose the right model?

Before you purchase a device, consider in detail where exactly you are going to install it:

• If you are going to mount a flow-through boiler in the bathroom, then the best option would be a water heater combined with a shower. A model with shower and faucet allows you to use hot water in the shower and wash basin. In this case, no new wiring with complex branches is necessary.
• Another feature is the mounting of a water heater for a shower cabin. In any case, fastening must be done outside the cabin (immediately behind it or from above). The choice of a specific model depends on the installation location of the device.

Food:

• After you have decided on the installation location of the device, it is necessary to conduct a power cable. Since the energy intensity of the flowing boiler is quite high, experts recommend the use of a copper three-wire wire with a cross section of 2x2.5.
• It is also necessary to take care of arranging a good grounding. In no case can you install the device without it.
• The cable must be pulled from the apartment distribution board.

Important! For safety reasons, it is necessary to install a 32 A machine in the shield

Ideal if you can stretch a solid cable. The place to install the outlet must be chosen so that it is as far away as possible from the water heater. It is necessary to use a socket protected from moisture, with grounding.

Mount

It is necessary to fix the device to the wall using the appropriate dowels. The parameters of the dowels must be selected so that they correspond to the fastenings on the water heater itself.In some cases, you will need to remove the rear panel of the boiler.

Often fasteners come with a water heater. If they are of good quality, you need to use them. If they are not too strong, it is better to purchase mounts separately.

How to drill walls? If they are tiled, then they use a special drill with a tip from Pobed. After the tile is drilled, you can use a drill with a conventional drill.

Important! The device must be fastened only in level, without distortions.

Connection Nuances

The next step is to connect the boiler to the water supply system. Instantaneous water heaters are sensitive to dry operation. Therefore, before connecting to the network, it is necessary to fill the device and “spill” it in order to expel all the air.

Installation in the shower

The biggest difficulty in installation work is to choose the right electrical cable. The boiler is connected to the water supply using a hose from the shower. There are two mounting options here:

• Between the washbasin and the bath, if you want hot water to be supplied to these two devices.
• Over the bathtub.

Installation for washing

How to install a flowing water heater in the bathroom - figured out. Now - about connecting the device to the water supply system in the kitchen. The boiler in the kitchen is mounted below, while remaining hidden behind a cupboard.

Connection to the water supply system is slightly different:

1. Install a tee on the cold water outlet.
2. Use the first branch to supply water to the mixer, the second - to supply water to the boiler.
3. Disconnect the hose connected to the hot water supply from the system and connect it to the outlet of the hot water heater.
4. Put a cap on a conclusion of a hot water supply system.

Do-it-yourself installation of the instantaneous water heater is completed.

Important! Do not forget to double-check the correctness of all connections before starting the system.

Test work

The startup algorithm is as follows:

1. First open the water supply to fill the boiler.
2. Turn on the heat only after a good pressure appears.
3. Turn off the system in the reverse order: starting with the heating system.
4. The faucet can be turned off after the heated water comes off.

Important! It is undesirable to turn on the heating if the water pressure is not strong enough.

As you can see, not everything is as complicated as it seems. To install a flowing water heater with your own hands is quite realistic. Be extremely careful and careful when performing installation work, and then everything will work properly and reliably for a long time.
