Water heater: what firm better equipment

Heater storage-type compact size

Note! In some cases, the operation flow units wiring can not withstand such loads.

Cumulative equipment makes it possible to receive the heated liquid for a sufficiently long period of time. Depending on how fast the cooling water or consumption, heating is carried out. This process is automated and requires no human intervention.

Scope of the water heater:

• suburban and private homes;
• office rooms;
• apartment;
• Beauty Salons;
• country houses and cottages;
• shop at the enterprises.

Functionality of this equipment is useful wherever there is a need for a hot water.

The market offers a wide variety of water heaters

Apparatus accumulative electric heaters horizontal and vertical

storage-type equipment is a fluid reservoir (tank), inside which the heating element is mounted. The basis of operation of the device based on the principle of action thermos, water heating is performed to a temperature of 50-85 degrees Celsius. After that, heating is switched off, and the unit continues to keep warm. When water is consumed (tap opening), part of the liquid from the tank, and in its place is supplied cold, which is to be heated again.

Accumulating constructs may be free-flow and pressure head, in other words, the equipment can be compared with the effect of operation of the electric kettle.

The principle of operation of the electric heater

Domestic appliance device includes having the following structural components:

• Tank with an inner seating and capacity of 10-20 liters;
• anode formed of magnesium (element inhibits the formation of rust);
• electric type heating element, or PETN;
• insulating layer separating the outer and inner coating (element contributes to the conservation temperature after heating);
• the safety valve (pressure level decreases when increasing);
• thermostat (item, set temperature and controls it to a certain point).

Note! Power PETN can reach 1.5-2.5 kW. On modern shelves you can find models that can carry out the work in two modes: heating and duty.

Advantages and disadvantages of the storage equipment

Due to the large number of advantages, the heaters are stable popularity among a large number of consumers.

Advantages of the equipment:

• the heating element has a low capacity;
• possible to connect several points of the fluid supply to one unit, as the apparatus is designed for the pressure generated by running water, and locked at the outlet valve;
• at low power because it is not necessary to install wiring, plug;
• the heater may be set farther than the point of water intake is located;
• via the mixer is assigned a fixed temperature and water flow rate;
• simple and convenient operation system;
• always available in a certain amount of heated fluid;
• design for a long time keeps the water in a heated state.

Storage water heaters are more powerful than with flow

Deficiencies are not many, but they exist. The equipment has a large size, it is impossible not to consider when buying and installing the unit. Shopping accumulating electric heater 10 liters under the sink to wash dishes will suffice. For taking a bath or a shower unit need more capacious tank.

Hot water can only be used after heating it is formed. Therefore it should be liquid preparations in advance.

Criteria and features a selection of water heater for questioning: how to choose the optimal device

To make the right choice when buying a water heater, should be guided by a number of selection criteria. Any design in operation is exposed to certain destructive factors. These factors include:

• sharp temperature jumps;
• aggressive active ingredients;
• high pressure.

Useful advice! When choosing a heating equipment in the store, is to ask the consultant about availability of anti-corrosion coating in the favorite models of boilers. This type of coating effectively protects against the damaging influence of aggressive substances.

Water heater harmoniously fit into a modern bathroom design

The weak points in the construction of any heater are placing weld zone. In these areas during the operation eventually appear leakage. From this it appears that the preferred embodiment fly cylindrical product, and the acquisition of a volume of 10 liters water heater electric flat better avoided. The moment caused by the fact that the cylindrical shape has a high resistance against pressure. However, this does not mean that the flat water heaters do not win in other ways.

Choosing the boiler tank with the appropriate volume

The optimal design of such a heater which provides satisfaction of the needs regarding hot water and thus remains economical. Choosing a water heater tank with an appropriate volume - the first step to buying a profitable unit.

Presented in hardware stores can be equipped with cisterns of various sizes. The minimum size of 10 liters, larger items can be up to 150 liters capacity.

Choosing a water heater with an appropriate volume of the tank - the first step to buying an economical device

Kitchen belongs to the category of premises that need daily in hot water, which is consumed at the kitchen work and wash the dirty dishes. To do this, you may need to average 10-25 liters. To fill the bath having a standard size, need about 50-70 liters. Use of shower stall for water treatment is accompanied by a smaller water consumption. Enough for making the tank with the soul capacity of 30-50 liters.

For a family of two people, in the tank accumulating the electric heater 80 liters will be sufficient. In homes where a large number of people, you must install the equipment capacity of 120 liters.

Useful advice! Equipment for 120 liters is able to provide a large family with water, provided an economical expenditure. To not experience shortage of hot water is recommended purchase unit 150 liters.

Horizontal storage type water heater

Anti-corrosion protection for heater capacity

Virtually any heating device there is a special protective layer. He prevents corrosion that can cause serious damage to the equipment. Protection - is not the only function of such a coating, it brings additional benefits, making the design attractive and harmonious heaters in interiors of bathrooms or bathrooms.

There are several types of tanks:

• stainless;
• titanium;
• enamelled.

On the inner side wall of each tank, the heater is constantly in contact with the liquid water exposure provokes rust. Through the application of a coating of stainless steel, this unpleasant moment can be avoided, which will extend the life of equipment.

Special protective coating ensures a long service life

On sale you can find tanks with corrosion-resistant coating. In most cases, it may be glass porcelain or titanium plating.

coverage option in the form of glass ceramics - the most amazing way to solve the problem of corrosion. However, there are some drawbacks. Abrupt temperature changes have a negative impact on the glass ceramic surface - it is covered with small cracks. The maximum warranty period of service in this case is only 5 years old.

On what type of control is better to stay

Electronic control type is characterized by a number of advantages: it is easy to operate, has a modern and neat appearance. But is there any expediency in the purchase of such equipment? After all, the price of a flat heater Electric storage 30 liters with electronic version control significantly higher than that of the machine with similar capabilities, tunable mechanical way.

EXAMPLE panel heater control device

Useful advice!If the area where you live, there are persistent problems with the supply network, for example, sharp power surges, shortages of electricity, it is not necessary to purchase equipment with sophisticated electronic stuffing. Any such differences may be the last for the heater, which may ultimately fail.

In most cases, the owners of the heating structures are not faced with the constant adjustment of the unit. The optimal parameters are set once, they take into account the preferences of the person and can be used daily without additional correction. Target control parameters assigned to relay.

Electronic Control The disadvantage is that the failure of at least one element in his complex system leads to failure of the entire heater. While mechanical control type is less susceptible to breakage, because it has a simple structure.

Heaters with an electronic control for this considerably higher in price

The choice of heating equipment for power level

All boilers storage type applying electrical energy to heat the fluid, there are one or steam heaters. These components can be of different capacity.

Small containers up to 15 liters equipped with single Tan, the power of this element is 1 kW. The accumulative electric heaters 50 liters sets heating element with a power of 1.5 kW. Large structures with a reservoir of about 100 liters equipped Tan, the power level of which is equal to 2-2.5 kWh.

Classic embodiments execution heaters have the form of a copper tube, it has a curved shape, and for each boiler model such specific shape. Inside the tube is placed nichrome filament, it serves as a conductor for electric current. This type of PETN called "wet". Water heating is carried out due to its contact with the copper pipe.

Outdoor water heater with a large volume tank

Important! Over time, due to impurities contained in water, covered fuser surface scum. The same happens with the inner surface of the container. To avoid premature failure, you should regularly clean the PETN and internal walls of the tank with water. This should be done at least once a year.

TEN as one of the most important criteria for selection of equipment

TANS called heating elements in the boiler. This abbreviation is a verbatim transcript of a tubular heating element. Taking into account the structural features it turns out that is not quite correct to use this abbreviation to describe a "dry" heating element, as is the custom to do.

Standard heating element of tubular type is created in the following sequence:

1. In the central part of a copper or steel tube placed nichrome filament.
2. The remaining space is filled with heat-resistant powder.
3. It carries out the procedure of rolling. As a result, the tube extending through openings, each of which is becoming smaller.

Apparatus PETN: 1 - ceramic insulator; 2 - fastening fitting; 3 - pin rod; 4 - heating coil; 5 - periclase; 6 - tubular sheath; 7 - sealant; L - length of PETN tubular sheath (cm); Lk - the length of the "cold zone" contact shaft (cm); La - active length (cm); Lh - fitting length (mm)

The result is the final shape of PETN - nichrome, which is separated from the shell of the insulating layer of a refractory powder. The resulting product has a tightly compressed structure. Subsequently it is cut into pieces of appropriate length and bent into a spiral shape. "Dry" PETN has a completely different structure.

Distinctions "dry" PETN from "wet"

According to statistics, buy cheap electric water heater storage-type solution takes about 90% of consumers. The remaining 10% of the purchase flow model. The electrical equipment is not the last role played by the heating element.

"Dry" is a spiral heating element. It is surrounded by a hollow tube made of ceramic.

Surface heating element "dry" type has an increased area

Note! After contact with steam under the insulating coating copper parts water particles it decomposes into oxygen and hydrogen. As a result of heating element is broken. The ceramic elements are less vulnerable because they spiral is protected from material falling into the liquid.

Water heater: which company is better? Comparative characteristics of the brands

According to consumer reviews, water heaters Electric storage with floor type of accommodation are the safest. In contrast to the flow models accumulation boilers are more massive and heavy construction.

Most of the manufacturers of the equipment produces a cylindrical shape, in other words, the design has a circular cross-section. Some brands of water heaters are made in the form of a parallelepiped with right angles. Most of them provides both horizontal and vertical type fastening.

Electric heaters are presented with a large number of models with different characteristics and device

For ease of installation boilers have additional equipment. This product incorporates the special mounting brackets. There may be two, sometimes three. These elements are fixed by pins or dowels, firmly fixed in the wall.

There are several types of walls that can be in the room:

• internal (walls separating one room from the other);
• The carrier (walls, retaining the basis weight of the building);
• false (walls and partitions made of plasterboard or other materials).

Experts recommend to perform the installation of the heater in the most durable bearing walls. False walls for this purpose and are totally under the weight of the device will fall. On the inner walls even possible to install a flat electric water heater 100 liters, provided through use of studs.

Scheme separating water non-pressure electrical heater for two mixers: 1 - free-flow heater; 2 - Mixer with open hot water tap; 3 - the hot water supply valve; 4 - water drain valve for preservation; 5 - tee; 6 - hot water flow switch; 7 - 4 comb connector; 8 - goose with a slot on the nose; 9 - Mixer valve in the "open"; 10 - nozzle hot water supply; 11 - a cold water supply pipe; 12 - cold water input line
