Are there any disadvantages?

• With a regular and significant consumption of hot water, it costs a considerable amount.
• If you use a powerful device, you need a thick cable.
• The device with a small capacity does not provide sufficient heating of the water, especially in the winter.

Important! Flowing water heaters with significant power are not even equipped with a cord with a plug so that the owner does not take it into his head to use an ordinary outlet.

Classification

All water heaters are divided into 4 groups.

• Cumulative. The water in the tank is heated.
• Flowing. The water that passes through the appliance is heated.
• Mixed. Can be used in both modes of operation.
• Filling.

Important! Outwardly, all water heaters are similar. The shape is rectangular or cylindrical, there is an opportunity to adjust the water temperature. The peculiarity of the storage equipment is impressive dimensions. In particular, if the boiler is designed for a large volume of water. Flowing water heaters are more compact.

But before you choose water heaters - cumulative or flowing, you need to know all their pros and cons, to study in detail all the technical characteristics.

Features of the instantaneous water heater:

• Compared to the storage device, the dimensions of the flow-through water heater are more modest.
• By appearance the equipment resembles a small box, which is fixed to the wall.
• Inside the tank there is a small size TEN.For rapid heating of running water, heating elements are made in the form of a spiral.
• An important design element is a flow sensor that monitors the appearance of water in the device and provides a signal to turn on the heating device.
• Flow-through water heaters are also equipped with temperature controllers.

Pressure and non-pressure flowing water heater: connection features

There are flow-through electric water heaters of system and individual type. The system device( it is also called the pressure device) cuts into the water risers. Such a heater can serve several points at once:

• Washbasin.
• Shower.
• Sink in the kitchen.

Important! Low-power pressure installations, designed for 8-9 kW, are capable of heating a small amount of water. More powerful devices( up to 32 kW) are rated for 380 V( three-phase).

Individual heaters are connected to cold water. They are equipped with a flexible hose with a nozzle or a sink for cleaning. This - a good option for giving or as a temporary measure for the period of shutdown hot water.

Control types

The control of flow type heaters can be:

• Hydraulic. At the input of the device there is a flow sensor, which sends a signal for switching on and off the heating element. The disadvantage of such a system is the inclusion of one power. There are devices with power control( push-button switching).
• Electronic. The device is controlled by a microprocessor. The device is monitored by several sensors that support the set temperature.

Important! A flow-through water heater with hydraulic control heats the water quite weakly. The temperature increase is 20-25 degrees. This means that in summer you get water at a temperature of about 40 degrees, and in winter the water temperature that passes through the device will be just above 20 degrees, because the temperature of the incoming water is very low.

Models of higher power - system, have an electronic type control and successfully cope with the task of maintaining the set temperature. The drawbacks of these water heaters are:

• Relatively high cost.
• High power consumption.

But if you got such an installation, you can use water with the temperature set by you at any time of the year.

Which water heater to choose for an apartment:

fabrication materials The internal filling of the flow heaters can be:

• Copper. Heaters made of copper, thanks to the excellent thermal conductivity of the metal, quickly heat up the water.
• Steel. This is a reliable and rather durable option, if the water is not too stiff.
• Plastic. This is the most budgetary option with a short working resource. Despite the fact that for the manufacture of using strong grades of plastic, buying a protochnik is a rather dubious business.

Important! To power the device, use a copper wire. The wire cross section is:

• With a power consumption of up to 7 kW, at least 3.5 mm.
• For power consumption up to 12 kW - 4 mm.

With proper selection of the power cord and good grounding, the device will work stably.

Selection Criteria

Choosing a flowing electric water heater to understand which is best to buy, pay attention to the following:

• The variability of the operating pressure is the minimum and maximum values.
• The amount of power consumption.
• Material of the tank and heater.
• Degree of protection( location near the tap and shower).With what water the device can work.
• Degree of heating water for 1 minute.

All these values ​​are given in the technical specifications of the device.

Important! It is also useful to see reviews for a particular model. If we talk about the producing country, then the leaders in terms of quality are German and Italian companies. Chinese products are "as lucky", but the percentage of high-quality goods is also rather large, as many European companies transfer their production to China. In this case, the label indicates the original birthplace of the brand and the place of assembly. Most of such equipment works well, since eminent companies value reputation and strictly control the quality of products.

Flow-through water heater VS cumulative

How to choose an electric water heater for an apartment-cumulative or flow-through, it is easy to decide:

• The main limiting factor is the power consumption. If you want to heat water to high temperatures and in large quantities, think about whether you can install a powerful flow-through device in 7-8 kW?Will your wiring survive?
• Decide how often you will use hot water: periodically or permanently. For intermittent use or as a temporary measure for repair, a flow device is more suitable.
• If you use the heated water regularly, it is better to use a storage( boiler) device. Modern models hold the temperature well, so there is an opportunity to save electricity.

Now we have considered all the nuances of how and what better to buy a water heater running electric or cumulative. We hope you could make the right decision, and now there are no problems with hot water in your house.
