Water heater, flow electric: characteristics and types

Today not everyone can install a double-circuit boiler or a heating tank in an apartment or a private house, but it is possible to use all the advantages of hot water in a different way. To do this, there is a water heater with a flowing electric current. This is a very compact device, which does not require much space in small bathrooms. Also this device will not spoil the interior.

With the help of these devices, hot water can be used without any problems during the period when it is not supplied. Do not have to change habits and suffer. Today such equipment is produced by a lot of different companies. How to choose a suitable heater, what are they, who makes them? About all this read on.

Principle of operation of flow-through heaters

Water heaters of flow type are a special flask where the heating element is located. Also, in addition to the heater, the device is equipped with an automation and control system. The startup process occurs when the user opens the tap. The power of the heater is very high, so the running water is heated almost immediately. As for the temperature, it depends on the power of the head.

If you need very high temperature water, then reduce the jet. If the tap is closed completely, the device will automatically turn off. Despite the rather compact dimensions, the heater has sufficient power.

As a heating element, in addition to TETA, uninsulated spirals or gas burners can be installed in similar devices.

Types of flow-through heating equipment

All flow-through heating devices for water, which are offered to the modern consumer, can easily be divided according to the design features on the flowing water heater electric pressure or non-pressure. The difference between them in their capabilities. Thus, a gravity-free model can only be installed on a single water intake point, while pressure equipment easily supplies heated water to several such points.

Features of non-pressure heating devices

This equipment is most often installed in urban apartments. The power of the heaters can vary from 3 to 8 kW. The devices from ordinary sockets are fed. During installation, the system is connected to a cold water pipe or directly to a mixer. Non-pressure solutions have only one tap.

Some manufacturers produce heaters that are equipped with a nozzle-shower. Also in the kit there can be other details.

Water heater, flow electric: features

This equipment for household use has a high power, and also differs in the way it is connected. If in the case of a non-pressure solution it was sufficient to fix it on the mixer, then it is necessary to install it in the water supply system.

The pressure flow electric water heater can simultaneously serve several consumers. The water will be equally hot at all points. With such a device, it's hard to notice that summer and hot water are not available on the street, and the presence of such a heater will be felt at prices in the electricity bill.

The appliance can not be plugged into a household outlet. It is connected only to a three-phase network. Such networks are in the apartments, where an electric stove is installed instead of a gas stove.

Selecting a device by power

The rate at which water will be heated depends on how much power this or that water heater has with a flowing electric current. Capacity also depends on capacity.

In this case, you should not choose the most powerful device - you need to focus on the electrical power capabilities of the house. Often, the wiring power in the apartment is not higher than 12 kW, and on the market you can find heaters with a power of over 27 kW.

For an ordinary city apartment will be quite sufficient for those features that the water heater provides up to 8 kW. Naturally, the device can not cope with the filling of the bath, but it will be possible to take a shower or wash the dishes.

For those who want to receive immediately and everything and does not represent life without a hot bath every day, it is better to buy a water heater with a flowing electric current, whose characteristics are read by power from 13 kW.

Selecting the heater according to the consumption of water

The amount of water required depends on the number of inhabitants of the apartment. Selecting the device, you should focus on the necessary amount of water, which can provide this or that device. No less important is the parameter, such as performance.

This characteristic is measured in liters per minute and must be indicated in the documents to the instrument. Modern flow-through heaters with an average output of 3 to 8 kW have capacities from 2 to 6 l / min. This volume (6 liters) will be heated in 20 seconds.

Body and overall dimensions

If the water heater flowing electric electric has a low power, then install it directly at the point of water intake. It is important to find the right and proper place for the device. With this there will be no problems. Modern manufacturers make compact devices that do not take up much space. But there are quite large products. So, the average size is 150x300 mm.

Pay attention to the equipment, the body of which is made of plastic, metal or both.

Adjustment, automation, options

Choosing among some models, it is worth paying special attention to the availability of a control system. It can be either electronic or hydraulic. On more modern and technologically advanced models, the front part of the casing is necessarily equipped with various adjustments. Installing the water heater flowing electric electric, photo of which can be seen in the article, please note that the temperature regulator should be available. To save energy, manufacturers have provided several modes.

Security

Since this is an electrical appliance, safe operation is an important parameter. Any modern water heater is equipped with various sensors. If any of them works, the heater will immediately turn off.

In order to avoid any problems during use, the device is equipped with thin filters and a check valve. The magnetic starter allows the heater to be turned on / off automatically.

The best among instantaneous water heaters

Choosing quality equipment, you should pay attention to AB Electrolux. The flowing pressure electric water heater of this manufacturer is an intelligent device in which there are all necessary adjustments for comfortable use.

In the line of models there are both pressure and non-pressure solutions. All equipment is completely safe, compact in size and easy to operate. The power of the device is different: from 3 kW to more powerful.
