Water heater with dry dense: overview, types, characteristics and reviews

Due to frequent shutdowns of centralized hot water supply, many people are thinking about purchasing water heating tanks. Their advantages are undeniable. Modern storage models are produced in a beautiful design, and, most importantly, are energy-saving. Such a result the manufacturers were able to get thanks to good thermal insulation. As a rule, heating the water in an average volume of the tank (80, 100 liters) takes 2-3 hours. After reaching the set temperature, the device automatically turns off the ten, and the liquid remains hot for a long time. Therefore, the energy consumption is on average 2-6 kW (depending on the amount of water consumption).

So, making sure of the efficiency of the storage boilers, you can go to the store. However, here the buyer expects a large assortment, in which the unknowing person is easily confused. At specialized points of sale, there are a variety of models: from classic round to flat. And you can buy a water heater with a dry tenor or wet. In a word, the differences are not only in the design design, but also in technical equipment.

For example, in budgetary models, water heating is carried out using a "wet" TEN. It comes into direct contact with the liquid. In such devices there are disadvantages (the formation of scale on the element, a decrease in temperature), and the advantages (heating occurs relatively quickly). For those who are not acceptable such disadvantages, the alternative will be electric water heaters with dry tans.

Immediately it is worth noting that the cost they are significantly different. For example, Gorenje EWH-100 V9 is sold for about $ 100. It is presented in a classic design, has a volume of 100 liters, is equipped with one tenon (wet type). For comparison, let's take a similar model that looks very similar to the EWH-100 V9, - Gorenje GBF 100 / UA (GBF 100). It already sells for about $ 160. Its only difference is the type of tena. In the model GBF 100 / UA (GBF 100) it is dry. Let's see if this difference in price is justified.

The device of water heaters with dry tenom

So, in order to highlight all the advantages and understand the shortcomings, it is necessary to understand how the water heaters are stored with dry damp. As for the case, in most cases it is made of metal - stainless steel or sheet steel, covered with enamel. Also there are models in which there are elements from plastic. In such cases, manufacturers use only a specialized constructive form. So, let's look at what this boiler consists of.

• Housing.
• Accumulation tank.
• Thermal insulation layer.
• Heating element - ten.
• Thermostat sensors.
• Thermostat.
• Magnesium anode.
• Control panel (mechanical knob or buttons).
• Valve.
• Pipes for cold and hot water.
• LED operation indicator.
• Power cord or power cable.
• Wall or ceiling mount (brackets).

Features of dry tena

A water heater with a dry tenon is a boiler that provides an apartment or a house with hot water. And what is the most important thing in this device? Of course, the heating element, or in other words - ten. This part consists of a spiral, which is equipped with contact rods. They are located at the ends. It is very important that the rods are insulated with a thermoplastic or sealant. For greater efficiency and reliability, the spiral is placed in a metal flask, due to which the heating element does not interact at all with water. Also, the working capacity of the thermostat is no less important. It must be protected from external influences and properly regulated.

Principle of operation

A water heater with a dry tenon operates on the basis of density. What does this mean? As you know, cold and hot water has a different density, so inside the storage tank it is moved by layers. Cold water through a special pipe enters the bottom of the tank. After that there is an automatic switching on of the heat that starts to heat it up to a certain temperature. With each degree, the water rises higher. Having reached the maximum index, it enters the system through the fence tube and, consequently, flows out of the tap. Due to this principle of circulation, the temperature of the liquid at the outlet is always high.

Advantages and disadvantages

A water heater with a dry tenon, however, like other types of boilers, has both advantages and disadvantages.

Pluses:

• Economy in work;
• Reduction of water quality requirements;
• There is no need for frequent cleansing;
• Large operating period;
• When replacing the foam, do not drain the water;
• The risk of electric shock is minimized;
• No air jams are formed;
• Presence of two heating elements;
• High level of thermal protection.

And now it is necessary to voice the shortcomings faced by the owners of such water heating tanks:

• Absence of universal heating elements. Models of dry tones are exclusive and do not fit all boilers;
• Service and spare parts are expensive;
• Cost of devices.

The main thing is to understand that the period of qualitative work of the boiler directly depends on the operating conditions. Many argue that appliances that are constantly used at maximum temperature, quickly fail. The optimal indicator is 55 °. Include a maximum only once a month in order to prevent from bacteria.

Gorenje

• Gorenje GBF 80 / UA (GBF80) - water heater with dry tenon. 80 liters - the volume of water. Consumes power 2000 watts. Heating to the maximum temperature (+ 75 °) will take about 3 hours.
