EVN (electric water heaters, boilers)

Elektrovodonogrevatel (EVN, boiler) is a great alternative to gas pumps and other water heaters. Among the benefits you can highlight the universality of fuel (electricity), simple installation and independence from the construction standards and specifications. In type EVN share on flow and storage. Instantaneous water heaters operate automatically and are included immediately after the opening of a hot water tap. Heating in them occurs instantly when the water passes through the device. In flow-through heaters can provide several advantages: compact size, installation in any available spot, instant heat, and hence the continued availability of hot water. However, in such a system, there are disadvantages: the power of these heaters is 2-25kW. Such power may require a separate posting. If you do not have opportunities to use such power, then you can use the electric heater of an accumulative type. It consists of the inner tank, internal heater, insulation and decorative shell. They are harder to install and more voluminous. In these types of EVN reliability depends on the material from which made the inner tank. This may be steel, covered with a special enamel - a reservoir is not very reliable because steel expands when heated, and no enamel. Subsequently, cracks cover, and then corrosion of the metal. In the more expensive models of boilers can be used stainless steel tanks, with a special technology of welding seams that prevent rust, as well as tanks coated biosteklofarfora and other advanced materials. Volume savings EVN can be from 5 to 2000 liters. Hot water discharges from the device automatically, and in return it receives a new portion of cold. Just boilers can be equipped with electronic panels at the board and timers. When choosing EVN should pay attention to its volume of calculation that for filling a standard bath you will need about 50 liters of hot water for showers and 35-40 liters per person. Find a compromise between power and heating rate. You should not "chase" for low prices. Your water heater should be such that you only have placed it and forget about the problems with hot water for many years. Construction and principle of the water heater EVN 1. Filling the tank 2.
