Today, the problem of heating water for various household and technical needs can be solved in several ways, and flow-through (electric) water heaters are one of these methods.
Instantaneous water heaters - features
Using water heaters of this type it is most rational in cases where a continuous supply of hot water is required and it is possible to allocate significant electrical power for this task. The performance of such equipment is determined primarily by the power of the heating elements installed in it.
Standard electric instantaneous water heater It is a small container with a heating element heat exchanger installed in it, designed for high-speed heating of the liquid passing through it (usually water). For calculation required power The following data is required:
- Supply temperature cold water(degrees Celcius);
- Water consumption (liters per minute);
- Required water temperature at the outlet of the water heater (degrees Celsius).
Instantaneous electric water heaters - advantages
The main advantage that is a feature of this type of units is that they provide the possibility of uninterrupted supply of hot water to water collection points, but it is important to note that sufficient power of the heating elements is required for sufficient performance.
Despite their high energy consumption, instantaneous water heaters are more economical than storage heaters (which use energy to maintain the temperature of already heated water). Another advantage that you need to focus on is that there is no need to save hot water. They can supply hot water continuously for an unlimited time within the limits of their resource.
The Termobalt group of companies produces and sells completely stainless instantaneous (electric) water heaters of the VETM type at the most favorable conditions. The assortment presented on our website is an extensive model range, covering both low-power devices and industrial installations power up to 300 kW.
For electric water heating, flow-through, storage, electrode water heaters and electric steam generators are used.
Industrial elemental non-flowing and instantaneous water heaters, equipped with heating elements, are used for low hot water consumption. They have low power, are simple in design, and are quite electrically safe, so they can be serviced by unqualified personnel.
Storage water heaters used in open systems water supply with an uneven hot water consumption schedule. Flow element water heaters are used in animal watering systems, feed preparation systems, and for heating small rooms and etc.
Electric water heating is carried out by elemental and electrode water heaters. Elemental non-flowing and flow-through electric heaters are equipped with tubular electric heaters (TEHs) and are used for low hot water consumption. They have low power, are simple in design, and are quite electrically safe.
Non-flowing water heaters used in open water intake systems with an uneven hot water consumption schedule.
Instantaneous (fast-acting) elemental water heaters used in systems for watering animals, preparing feed, and for heating small rooms.
Electrical energy is converted into heat when flowing electric current through water located between the current-carrying electrodes.
Electrode water heater type EPZ. It has two versions, differing in the drive of the power control mechanism (I2 - manual, I3 - electric drive). The design of the electrodes depends on the power of the water heater.
Water fills the space formed by the phase and control electrodes. Current flows from the electrodes of one phase through the water through the regulating metal electrode, then through the water and to the electrodes of the other phase. The power of the water heater is regulated by changing the area of the active surface of the control electrode.
Electrode water heating boiler KEV-0.4(Fig. 3) is manufactured with plate electrodes and is intended for heating water with resistivity above 10 mOhm. The power is adjusted from 25 to 100% of the nominal by changing the active height of the electrodes due to the movement of control plates made of dielectric in the interelectrode space. The power regulator drive can be manual or electric.

Electric steam generators are intended to receive saturated steam with excess pressure up to 0.6 MPa. They are used to meet technological needs, as well as in hot water supply and heating systems.
Basically, steam generators belong to direct electric resistance heating installations; their operating principle and design are similar to electrode water heaters. The classification of steam generators is similar to the classification of electrode water heaters.
Not so long ago, a new term appeared and became established in the family of water heaters - an industrial instantaneous water heater. Compared to a conventional one, such a water heater has a significantly larger volume, as well as very high performance.
Such water heaters are capable of providing hot water supply for a whole multi-storey building or, for example, an enterprise that requires large consumption of hot water.
What are the benefits of industrial water heaters? Firstly, such equipment can become an alternative central heating, since he is able to work on a permanent basis. And secondly, to be an addition in places where there are frequent outages. At the same time, you can significantly save money on heating.
Savings are achieved due to the composition of the equipment. The water heater is equipped with special sensors that record the desired temperature and turn it off in time. As a result, the water in a special tank is always hot. The water is heated using powerful heating elements installed inside the tank. Their advantage is fast heating.
But this market, like all others, does not stand still, moving forward. Thus, gas-based industrial heaters have recently appeared. There is an opportunity to save even more, because electricity costs exceed gas costs. This, in turn, is a kind of disadvantage, due to the fact that gas lines are not laid everywhere, and therefore do not always allow connection.
In addition to the above, it should be noted that industrial water heaters can replace a similar boiler room in those places where its construction is necessary, which will reduce costs in this area as well. This is confirmed by the performance of water heaters. And automation will allow you not to use large quantity specialists.
