Storage water heater 15 liters: instruction manual, installation and feedback

Each family consumes a different amount of hot water per day. Some people get to spend a smaller amount of storage, while someone has a bigger one. But there are certain norms that will help determine the choice. It all depends on the purpose of the boiler. So, the water heater of 15 liters is suitable for kitchen use or for washing hands and washing in a bathroom.

There are such layouts of a house or apartment, where without a small boiler simply can not do. For example, when the bath is far from the kitchen. In this case, it will be advisable to purchase a small 15-liter water heater for washing dishes and a large main boiler for bathing or showering.

Principle of operation

Storage water heaters of 15 liters have their distinct specialization. This amount is not enough to fully bathe in the shower, but that's for washing dishes it will be more than enough.

The water heater of 15 liters of volume operates in the temperature range from +35 to +80 degrees. In the tank where the heating occurs, a thermostat is installed. It is he who turns on and off the heater on the user-specified parameters.

Today electric water heaters with 15 liters of closed type are almost always used. There is always a liquid in the tank. If a faucet with hot water is opened, cold water flows into it under the same pressure.

A storage water heater of 15 liters allows controlling the temperature at the outlet by mixing hot and cold water from the plumbing system.

Cumulative and flow type

There are two types of heaters: flow and storage, which can provide the user about 15 liters of water. Each has its advantages and disadvantages.

The boiler draws water into the tank and heats it for a certain amount of time. We'll have to wait until the set temperature is reached.

Flowing water heaters do not have a storage tank. The integrated heating element immediately heats the flow through it. Consumption of water is not limited by the volume of the tank.

However, such a system will require the presence of good quality wiring and power and mandatory grounding. After all, the heating rate should be almost instantaneous. If the power of the heating element is not enough, it will be necessary to reduce the head. Especially in the winter. This is a big drawback, which has a running water heater. 15 liters is easier to heat with a boiler. Its heater has much less power. Therefore, drives are more popular than protochnikov.

Power

The greater the power of the heater's heater, the faster the desired temperature is reached. For 15-liter boilers, heating elements of 800-1500 W are very often used. At the same time, the water in the tank will be heated to 75 degrees in 36-22 minutes. respectively. This is an average calculation, because the temperature in the highway is different in summer and winter.

For example, the power of 1.5 kW, according to the instructions for use from the manufacturer, has a 15-liter water heater "Termex".

Among the foreign products there are other parameters of heaters. Thus, a 15-liter storage heater Ariston can have a power of 1200 watts. The time to reach the set temperature for this boiler will be greater than that of the Russian "Termix".

But a running water heater in the kitchen for normal operation will require about 4 kW of power. The issue of grounding here is not even discussed. Many models have a limiter that does not include a heater without its presence.

Tank material

The storage water heater of 15 liters has a different anti-corrosion coating. There are tanks made of stainless steel, steel with enamel, glass ceramics, titanium. And quite often manufacturers are developing their own technology to protect the tank. For example, a steel enamel boiler can be additionally protected with zirconia chips. According to experts, 15-liter water heaters "Termex" of the domestic manufacturer use the technology of micro-reinforcement of ceramic glass, which significantly reduces the risk of corrosion.

The stainless steel tank requires a mandatory grounding. If this is not done, there will be "wandering currents" when heated . They destroy the tank very quickly. Grounding makes stainless steel durable.

Water heaters of 15 liters, reviews of which were left by users, mark the lifetime of such a product without observing the requirements of the instruction as very short. No more than 1.5 years will have to change the boiler.

Type of heating element

Trying to extend the life of the boiler, manufacturers will improve the technology of manufacturing these products.

Today, the consumer is represented by two types of heaters. They can be open or closed type. In the first case, the heater is located directly in the water. Usually it is made of copper. But there are other options. For example, according to experts' opinions, there are accumulating water heaters of 15 liters with TEN, which has a silver coating. This additionally protects all internal elements of the tank and cleans water from bacteria.

Most often with a "wet" TEN installed magnesium anode. It prevents the formation of scale. Change it should be once a year.

There are heaters with a "dry" TEN. It is in a flask and is not exposed to water. This technology gives durability to the product.

However, no water heater is accumulated 15 liters, reviews about which experts leave, does not have a "dry" TEN.

The form

Overall dimensions and shape play an important role, even for such a small boiler, which is a 15-liter variety.

There are round water heaters, which are called a barrel. This is the standard form. But for the convenience of the consumer manufacturers produce small square or rectangular boilers.

For example, according to user feedback, such water heaters of 15 liters of volume, as "Ariston", "Fer", "Termex" etc. are very convenient. Their dimensions allow to harmoniously enter the technique into the interior of a kitchen or a bathroom.

A lot of non-standard forms are encountered. Electric water heaters of 15 liters open up the producers scope for creativity.

The main thing is to first measure the parameters of the installation site, and only then determine the shape of the product.

Additional Items

In addition to the accessories listed above, the boiler has additional details. The thermostat is very important for this device. It will protect you from overheating and will maintain the desired temperature in the tank. It is better if he has a second spare device. But this equipment is infrequent.

Very important is the insulation of the tank. This will determine the speed of cooling and, as a result, energy costs. A 15 liter water heater, reviewed by experts in various sources, has a smaller layer of insulation than large boilers.

However, due to the short period of heating time, such an indicator for the presented technique is less important than for a tank with a volume of 80-150 liters.

Customer Reviews

According to user feedback, earlier there were very high-quality boilers of products of such brands as "Ariston", "Burning", etc. However, over time, much has changed in production technology. Many new high-quality boilers have appeared, including domestic production.

For example, the 15-liter "Ariston" water heater, which can be found in various sources, has been marked by users as reliable only in the case of Russian assembly. Chinese production leaves much to be desired.

Domestic manufacturers are constantly improving and introducing new technologies. Water heater "Termex" 15 liters, the instruction on which application is strictly carried out (the boiler is grounded), will last longer than foreign analogues.

Expert Reviews

Professionals in the field of storage water heaters note that there is no significant difference between foreign and domestic producers. The production technique of China, Korea, which was purchased in a non-specialized store, is of low quality. These heaters may have a weak thermal insulation or a smaller thickness of the tank than in the case of analogues.

Substandard components become a frequent cause of breakdown.

Water heater accumulating 15 liters "Ariston", "Electrolux", "Bosch", "Combustion" are marked by experts as the most purchased. However, if they are incorrectly connected, they will not work for a long time without observing the requirements of the manufacturer's instructions.

Even the best boiler will need service once a year. Cleaning the tank and replacing the magnesium anode are mandatory conditions for the manufacturer to fulfill its warranty obligations.

Cost

According to the research, high cost is not always a guarantee of quality. The most expensive are recognized German, Swiss, French, Polish and Turkish boilers. Their price sometimes reaches 240 $.

However, few people are interested in the country of assembly. For example, the water heater Ariston 15 liters, whose cost is attributed to the mid-price segment, is surprising. After all, this device often has an assembly in Russia. And its high cost is explained only by brand name, and not by cost.

But the relatively inexpensive boiler of the Italian complete set "Fer" (about $ 70) is quite cheap due to the assembly in China.

Installation

Install a 15-liter water heater is fairly straightforward. It has a small weight. Depending on the configuration, it is attached above the sink / washbasin or under them. He can be on the sidelines. It is fastened to the wall using dowels. The tee-pipes are installed in the supply pipes, a bend is made. Cold water is connected to the boiler outlet. The hot water tap is connected to the second outlet on the tank.

Before entering the cold water, you should install a non-return valve and, if desired, a filter. This will extend the life of the product.

Then you need to open the water and check the operation of the system. If the water is running normally, the boiler is installed correctly.

The electrical supply can be made via a power outlet or machine.

Having familiarized with such an instrument as a water heater of 15 liters, its device and types, you can choose a quality boiler. It will satisfy the need for hot water in the kitchen or in the bathroom. Compliance with the manufacturer's instructions, proper installation and operation will greatly extend the life of the boiler.
