How to install a water heater

General rules

You can install a water heater in two ways - yourselfor hire a specialist. Each of these options has its advantages and disadvantages. If there are means, then the second method is obviously easier. But not all "afford" the payment of such services. That is why many people prefer to put the water heater on their own. On average, with the necessary tools for installation, it takes 3 hours. If there is absolutely no experience with plumbing, then it is perhaps more reasonable to instruct the installation specialists. To entrust installation works to the master it is necessary also in the event that you live in an apartment of a multi-storey building. You will install yourself - you risk flooding your neighbors.

If any experience in such works is available, you can try to perform the installation of the water heater with your own hands. In doing so, you get a lot of pluses. In particular, to the undoubted advantages of self-installation of equipment can safely be attributed savings in money and time. In addition, thanks to this work, you will gain skills that will become very useful in the future when repairing and servicing the same water heater. If you need to repair, you do not need to call a wizard for this work. After all, with the dismantling, you can manage on your own.

Principle of operation of

water heaters Electric water heaters mainly use storage and flow options. In the first case, water is heated in a special tank. This kind of aggregates is considered the most common. He got his popularity thanks to an attractive price. In addition, such installations are valued for the fact that they do not have special requirements for wiring.

With regard to a flowing water heater, the heating of the liquid occurs when it passes through a special flask. It is in this flask that the basic heating element is installed, which requires electricity. Usually such a water heater is placed on the tap itself with tap water. Thanks to this design, the liquid can be heated to about +28 degrees. But this requires a lot of electricity, which can not always withstand the electricity in old buildings.

All flow units can be divided into:

• single-phase,
• three-phase.

As a heating element, a spiral or a heater can be used. It should be noted that in comparison with the first variant the second type of aggregates consumes about 12-18% less electricity. If the water in the water pipe is sufficiently rigid, it is recommended to use models of water heaters equipped with a spiral. It serves as an element of heating.

Other types of water heaters

In addition to electric heaters, other models are also used:

• Induction. This kind of heaters definitely deserves attention. A distinctive feature is that in their tanks with water, when heated, scale is not formed. This is due to the fact that the alternating magnetic field from the inductor simply does not allow the scale particles to settle on the surface. Thanks to this, it is possible to maintain the efficiency of the heater for several years. These units have many advantages, so they are very popular among buyers.
• Gas. To put such a heater makes sense only if there is a gas column. Otherwise it just will not work. With your own hands to put the gas column in its absence is impossible, i.e.this is prohibited by law. But even if it is available, in order to modernize it, participation of gas service employees is required, which has all the necessary certificates and licenses for such work. Only they will be able to fulfill all the necessary work by all the rules.

How to connect a water heater

Preparatory work of the

Regardless of the type of water heater to be installed, it must be installed in compliance with the basic safety rules. It is also advisable to listen to the demands made by a specific manufacturer. They are usually indicated on the packaging of the goods or in the instructions attached to it.

We present to your attention some general recommendations that will be useful when installing water heating units:

1. . Until the work is started, it is necessary to select the correct area for installation of the device. So, during the whole period of using the unit, it must be provided with free access.
2. In addition, it is important to choose the right wall, where the device will be suspended. In addition, you need to take care that the wall can withstand a double weight.
3. You should also determine the state of the risers and pipes. Sometimes, with such a check, it turns out that the pipes are to be replaced. For example, this is required if the pipes are very old or there is no place where the water heater could be connected.
4. In addition, it is necessary to know the condition of the wiring, what section of the wire is in it and whether it is able to withstand the future loads from the water heater. And you need to do this before the work starts.

Before starting to install the water heater, you must prepare all the necessary tools in advance:

• The wall will need to make holes. Therefore, a punch is useful.
• The work will also need a screwdriver( two- and four-sided), a tape measure, a set of wrenches.
• For the convenience of trimming small parts you will need cutters and pliers.
• For waterproofing it is necessary to purchase a tape Fum or a special paste.
• One way or another, you need a plastic pipe.
• Even during the installation of the heater, stopcocks, tees, hoses and towers are required.
• If it turns out that the wiring is to be replaced, it will require a three-wire wire of the required length. It is useful and the scheme of the water heater.

How to install a water heater

This is a fairly light and small device. Therefore, it is not difficult for them to find the installation site. As an option, it is allowed to install the unit under the sink in the kitchen. If you purchased a high-capacity water heater, take care of replacing the wiring. Be sure to find out some information about the installed counter, namely, on what capacity it is calculated. If it can withstand a current strength of not more than 40 A, then it will have to be replaced. To connect this type of unit, the machine with a rated current of at least 32A is most suitable. In addition, a 3X6 PVA cable is required.

When the problem with voltage supply is solved, you can start the installation process itself. Immediately need to say that this type of device can be connected in two ways - stationary and temporary. The latter uses a shower hose. In this case, in advance, you need to prepare everything you need to supply cold water. In this case, you can not do without such elements as a tee, a hose and a stopcock. The sequence of their installation should be the following: first the tee cuts into the cold water pipe, the stopcock is installed in place, and then the input of the device to be installed and the tap are connected by a hose. We can assume that the flow unit is installed. Check whether the heating is working: open the tap, from which the heated water should come, and turn on the water heater itself.

Regarding the stationary installation method, in this case the intake and supply of water will work separately from the general water supply system. You will need to buy more than one, and a pair of tees - one for each of the two pipes( cold and hot water).

When this is done, you can install the cranes. At the same time, the joints should be sealed to prevent leakage with a tape or a special adhesive paste and a packet. The pipe should not flow after this, only after making sure of this, it is possible to connect it with the water heater input. In doing so, inspect the connections for leaks. If everything is in order, then you can plug the heater plug into the socket - when the tap is opened, the heated water should go.

If the heating device was put in a multi-storey building, then after using the water it will be necessary to cut off its supply each time.

How to install a storage water heater

Installation procedure:

1. You should start by attaching the unit itself. To do this, it is recommended to mark out the location of the future installation. Take the tape measure and measure the distance between the heater and the holes of the anchors.
2. Now on the wall on the removed sizes it is possible to put labels where holes will be made. Depending on the design of the instrument, it may take 2 or 4 holes.
3. When the holes are ready, dowels and hooks are inserted into them. It is important that the same distance is present between the anchors on the heater and the hooks. Otherwise, they will not be able to put them on the hooks, and you will have to make measurements and holes again. So be careful.
4. After the device has been secured, you can start connecting it. In this case, the places for connecting the water heater must be withdrawn. Places of water inlet and outlet from the installed device are connected to other parts of the system by means of hoses or pipes.
5. The cold water inlet, which is usually marked in blue, must be fitted with a special valve, which allows you to relieve excess pressure if necessary.
6. It is very likely that in the future the water heater will have to be serviced. It does not matter if this is planned or unplanned repairs, but for convenience, cut an additional tee. With its help, you can easily drain water from the tank.
7. To ensure the tightness of the connection point, wrap the tape with tape or a thread with a special adhesive paste.
8. With plumbing finished, you can do electrical work, and, in particular, bring power. Contacts on terminals and devices are conventionally denoted by letters."Phase" is usually a brown wire. It is designated by the letter A. "Zero" is carried by a blue wire and is denoted as N. The earth is usually a yellow or some other cable.

If everything is done correctly, the indicator on the working device will light up. Then, according to the instructions, you should start adjusting the temperature. When these jobs are completed, the storage unit can be used in everyday life.
