TEN for Ariston water heater: varieties and their characteristics

Water heating equipment brand Ariston is of high quality. But even its individual parts can break under severe operating conditions. Therefore, it is extremely important to take into account the basic nuances of handling such equipment.

Special features

Presenting a comfortable apartment or even a private house without hot water today will not work. Where it is impossible to use central heating, it is necessary to put water heaters. If such a system is chosen correctly and installed properly, it will provide for the everyday needs of a large family quite effectively. The decisive element in the heating equipment is the heating element, which is a copper or stainless steel element. The tube inside it contains a spiral through which a strong current passes.

The heater for the Ariston boiler and any other is different from those of similar devices that are mounted in electric kettles or in washing, dishwashers. Its total electrical power is noticeably larger, as it requires heating a significant amount of liquid in a short time. The company produces both “wet”, made according to an open pattern, and “dry”, hermetically closed, heating elements. Ariston Corporation uses to make its heaters an alloy of copper with chromium and nickel.

Specially designed flange made of brass allows you to give the maximum amount of thermal energy.

Capacity varies by model. All the highest quality heaters are equipped with a thermostat. This unit stops the operation of the device as soon as its temperature becomes critical. On the other hand, the automatic system gives the command to start and when the temperature drops below a certain threshold. Therefore, you can not be afraid, when buying Ariston products, that there will be any negative phenomena or there will be a risk of fire.

Types and device

Ariston water heater for 100 liters can be represented, for example, by the model Abs Pro R 100V. For this model, heaters are needed that are able to raise the water temperature to 75 degrees and are able to be under fluid pressure from 0.2 to 7 atmospheres. The heating control is carried out according to the mechanical scheme, the indicator shows only on and off. There is a thermometer in the system, as well as a limiter for the degree of heating. The protective anode is made from magnesium.

80 l wall mounted heater is Abs Blu R 80 V Slim. The device must provide direct heating power of 1.5 kW. Management is organized mechanically, the highest temperature created is 75 degrees. The wet-type apparatus is equipped with an immaculate shut-off automatics. The developers have provided active prevention of corrosion due to a large magnesium anode.

For water heater Abs Vls Evo Inox PW 50 A capacity of 50 liters provides for the use of two heating elements at once - one per 1000, the other 1500 watts. Modern design allows to reduce energy consumption by 12 -16%. In this case, the speed of work is very high compared with similar models.
Abs Blu Evo RS 30, as the name implies, is designed to heat 30 liters of water. The total power is 1500 W, accelerated heating by the designers is not provided.

Up to 60 degrees, the water heats up in 70 minutes. The only wet heater should operate on a current of 220 V with a water pressure up to 8 bar. Gas boiler for 200 liters of flow type Marco Polo Gi7S 11L FFI is a worthy competition to the above electrical devices. Here are its main parameters:

total power of 22 kW;
warming up of water of 75 degrees;
fluid pressure from 0.6 to 8 bar;
the amount of moisture heated per minute to 11 liters.

It is noteworthy that this model illustrates the visually impressive capabilities that other - already electric - devices from the Italian manufacturer, belonging to a high price class, have. Reliable overheating protection and automatic troubleshooting of the device are provided. The system is able to regulate its power smoothly, change the intensity of the passage of water and its temperature. Supply of programmed amount of water is possible. Open heating elements, including those placed in 15-liter tanks, can heat water faster and are relatively inexpensive.

But they have a serious problem - increased current consumption, insufficient security and short-term operation.

Who wants to get a reliable and economical product, gets a dry-type heater. True, there is no reason to hope for rapid heating of the fluid with such equipment. For an insignificant tank capacity, this does not play a special role, since it is difficult to notice the difference here. In addition to the magnesium anode, the temperature limit by the thermostat (the higher it is, the more active the corrosion) contributes to the preservation of the heater for a long time.

In dry heating elements designed for both 1000 W and any other power, there is no boundary between the casing and the flange. The internal surfaces are invariably covered with protective enamel. At such a step, engineers go to reduce the rust rate additionally. In both wet and dry circuits, a magnesium anode is used, which “pulls” the oxygen released from the water. Therefore, the latter will not be able to react with the steel parts of the housing and the heater itself, and therefore the corrosion process will be slowed down.

Rely on one enamel is not worth it, because the constant temperature drop leads to its cracking.

The anode is placed in the immediate vicinity of the heating element, and therefore should be considered in conjunction.Returning to the main topic, it is worth pointing out that Velis heating parts are included in any table of a model rating. TEN of a wet format with a flange with a diameter of 12.5 cm, in which 5 holes are made, is used for this model. The voltage is standard, two blocks cannot be used immediately, the type of connection is a pin, contact M5.

How to replace?

In case of failure of the heater in a system attached to the wall, it will be quite possible to get it even on its own. In systems that are not equipped with electronic display, you need to be prepared for a very bad look inside the device. It is recommended to remove the water heater as a whole from the attachment and spread it out on a flat horizontal platform. The cover is hooked, this is enough to open the system.

Disconnection of terminals can be done immediately, the main thing is not to forget what they were connected to. Marker notes or even a photo will help here. By disconnecting the wires connected to the thermostat, you can pull out the heater directly. To do this, take out the fasteners that hold it. Such a procedure is performed not only when replacing, but also during repair, maintenance or troubleshooting.

Of course, in order to change the heater, the device is previously de-energized. When finished, put the new unit in place and carefully assess whether there are any leaks. Since the wiring is located nearby, great care will have to be taken. At the time of work, it is recommended to remove the thermocouple removed away so as not to break it.

Attention: without knowing for certain what kind of heater is installed in the heater, it is better to take a damaged sample before purchasing it in the store.

Tips and tricks

Before replacing the heating element in the water heater, it is necessary to completely drain all the water from the tank. Check whether this item is broken, or the boiler does not work for some other reason, you can only a multimeter. RCD should be designed for 10 mA, if you do not comply with this requirement, you can face the penetration of current in the most unpredictable places. In some models, for access to the electric heater, it is necessary to dismantle the hot and cold water valves; more detailed information provides technical documentation.
