In our country the issue of hot water is one of the most urgent. It is rare to find apartment buildings in which the centralized supply of hot water works year-round without interruption. And even if there are such houses, during the technical work, the tenants still have to go without hot water for several weeks. In such cases, water heaters help out. The question of how to choose a water heater , is asked also by the owners of private houses or villas, because there they are simply necessary.
Water heaters are electric and gas, the latter most often we are accustomed to calling columns. Undoubtedly, gas columns are cheaper to use. But with their installation you have to stay longer. First, a gas pipe and a branch for combustion gases are needed. Secondly, self-gas water heaters are very difficult to install. Installation of electric water heaters is much more complicated, but they are more expensive to use.
Electric water heaters are of two types: flow and storage, which still have the name of capacitive. Let's see,
In flow-through boilers, there is a ten, which is powered by electricity. He heats the water. The principle of operation of the instantaneous water heater is that the water enters the pipe in which the ten is located and flows out hot from there.

The huge advantage of a running electric water heater is that it has small dimensions and the water heats up instantly. The downside is that for a large family, in order to heat the required amount of water for bathing or showering, it is necessary to install a water heater whose capacity is greater, accordingly, there will be much more electricity consumption. Also, the minus of the running water heater is its price, it is more expensive than the storage one.
When installing a flow-through water heater, it is necessary to install additional wiring and install a fuse.
The second type of electric heaters is accumulating. Such boilers also have ten, but water is heated not in a pipe, but in a tank. It takes more time to heat water, but less electricity. The disadvantage is that the water must be heated in advance. But, since these tanks are covered with heat-insulating material, water can be heated at night and all day to use it.
Storage electric water heaters
The storage water heater can be connected to several points, for example, for a bathroom and a kitchen. It can also be noted that the temperature of the water in the storage tank is greater than in the storage tank, so that when mixed with cold water, more warm water is produced.
When choosing the volume of the electric water heater, first of all, it is necessary to determine what it will be used for. If for washing hands, then there will be enough tank from 5 to 15 liters. If you want to put the boiler in the kitchen, you also need a small tank of up to 30 liters.

But in a bathroom, for a family consisting of more than two people, it is best to put a boiler for 80-100 liters.

The special feature of storage water heaters is also that they need to be taken care of regularly, that is, periodically cleaned. The scale forms a scale that can break the water heater. To descale less, it is desirable to pass the water through the filter. Filtering of water is mandatory in cases where you have hard water. In apartment houses with tap water this happens less often, but the water from wells or wells that are used in private homes is often too hard. At the same time the formation of scale occurs instantaneously, and your heater will not last half the time. Clean the boiler is not so difficult, but it is best to call the master.
For large storage tanks, the volume of which is more than 200 liters, there are separate rooms. Therefore, it is impossible to establish it in a small one-room apartment, and there is no need for it. Such large water heaters are usually installed in private houses with several bathrooms or in mini-hotels for several rooms. Most often these tanks - floor.

The same running tanks, with a volume of 80-100 liters, can be hung on the wall directly in the bathroom, in the kitchen, in the laundry or in the bathroom. It can visually reduce the room, but at the same time you have a huge advantage - hot water constantly. Small tanks from 5 to 15 liters can be placed under the shell.
If you use and care for the boiler correctly, it will last a very long time. The most important mistake often made by consumers is the inclusion of a flowing water heater before the water runs into it. Therefore, the first thing to remember is that after installing the heater and connecting it to the water supply, it is necessary to completely fill the tank with water, and only after that to switch on the power grid. Another mistake in the use of boilers is the frequent switching-on and off of electric storage water heaters in order to save. Such actions on your part can lead to premature failure of the heater. If you follow the instructions, then from all other troubles your boiler is reliably protected.
