Each family consumes a different amount of hot.water per day. Someone turns out to spend less displacement, and someone - more. But there are certain rules that will help determine the choice. It all depends on the purpose of the boiler. Thus, the water heater of 15 liters is suitable for kitchen use or for washing hands and washing in the bathroom.
There are such planning house or apartmentwhere without a small boiler just can not do. For example, when the bath is far from the kitchen. In this case, it would be advisable to purchase a small 15-liter dishwashing water heater and a large main boiler for taking a bath or shower.
Principle of operation
Storage water heaters of 15 liters have their own clear specialization. This volume is not enough to fully bathe in the shower, but this will be more than enough for washing dishes.
Water heater 15 liters of volume working intemperature range from +35 to +80 degrees. In the tank, where the heating takes place, a thermostat is installed. It is he who turns the heating element on and off according to the parameters set by the user.
Today almost always applyelectric water heaters on 15 liters of the closed type. There is always liquid in the tank. If a hot water tap is opened, cold water flows under the same pressure.
The storage water heater of 15 liters allows you to control the outlet temperature by mixing hot and cold water from the plumbing communications system.
Accumulative and flow type
There are two types of heaters: flow and accumulative, which are able to provide the user with 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.
Instantaneous water heaters do not have a storage tank. Built-in heating element immediately heats the stream passing through it. Water consumption is not limited by the volume of the tank.
However, such a system would requireelectrical wiring of good quality and power and mandatory grounding. After all, the heating rate should be almost instant. If the power of the heating element is not enough, you will have to reduce the pressure. Especially in the winter. This is a big drawback, which has a flowing water heater. 15 liters is easier to heat with a boiler. His TEN has much less power. Therefore, drives more popular protochnikov.
Power
The greater the power of the heater water heater, thefaster to achieve the desired temperature. For 15-liter boilers, heating elements of 800–1500 W are often used. In this case, the water in the tank will heat up to 75 degrees in 36-22 minutes. respectively. This is an average calculation, because the temperature in the highway is different in the 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 "Termeks".
Among foreign products there are otherparameters of heaters. Thus, the 15-liter hot water heater "Ariston" can have a power of 1200 watts. This boiler will have a longer time to reach the set temperature than the Russian "Termex".
But the instantaneous water heater in the kitchen fornormal operation will require about 4 kW of power. The issue of grounding is not even discussed here. Many models have a limiter that does not include the heater without its presence.
Tank material
The water heater is accumulative 15 litersvarious anticorrosion coating. There are stainless steel, steel with enamel, glass ceramics, titanium. And quite often, manufacturers develop their own technology to protect the tank. For example, a steel enamelled boiler can be further protected by zirconium chips. According to experts, the 15-liter water heaters “Termeks” of the domestic manufacturer use the technology of micro-reinforcement of ceramic glass, which significantly reduces the risk of corrosion.
Stainless steel tank needs a mandatorygrounding If this is not done, then "stray currents" will be present when heated. They destroy the tank very quickly. Grounding makes the stainless steel durable.
Water heaters 15 liters, reviews of whichleft by users, note the life of the product without the requirements of the instructions as very short. No more than 1.5 years will have to change the boiler.
TENA type
Trying to increase the life of the boiler, manufacturers will improve the technology of manufacturing these products.
Today, the consumer presented two types of heaters.They can be open or closed. In the first case TEN is directly in the water. It is usually made of copper. But there are other options. For example, according to expert reviews, there are storage water heaters of 15 liters with heating elements, which has a silver coating. It additionally protects all internal elements of the tank and purifies water from bacteria.
Most often with the "wet" TENOM install magnesium anode. It prevents the formation of scale. It should be changed once a year.
There are heaters with "dry" heater. It is in a flask and is not exposed to water. This technology gives durability to the product.
However, none of the water heaters accumulative 15 liters, reviews of which are left by the experts, do not have a “dry” heater.
The form
Overall dimensions and shape play an important role even for such a small boiler, which is the 15-liter version.
There are round water heaters, which are called barrels. This is the standard form. But for the convenience of the consumer, manufacturers produce small square or rectangular boilers.
Например, согласно отзывам пользователей, очень such water heaters of 15 liters of volume are convenient, as "Ariston", "Fer", "Termeks", etc. Their dimensions allow you to harmoniously enter the equipment into the interior of the kitchen or bathroom.
Many found non-standard forms. Electric water heaters 15 liters provide manufacturers with room 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 components listed above, the boilerhas more details. Thermostat is very important for this device. It will protect from overheating and will maintain the set temperature in the tank. It is better if he will have a second spare device. But such a complete set is rare.
Isolation tank is very important.The cooling rate and, as a result, energy consumption will depend on this. The storage water heater of 15 liters, reviews of which were left by experts in various sources, has a smaller insulation layer than large boilers.
However, due to the short heating time, such an indicator is less important for the presented equipment than for a tank with a volume of 80-150 l.
Customer Reviews
According to user reviews, previously there were very high quality boilers made by such brands as “Ariston”, “Combustion”, etc.
For example, the water heater "Ariston" 15liters, reviews of which can be found in various sources, marked by users as reliable only in the case of the Russian assembly. Chinese production leaves much to be desired.
Constantly improve and introduce newtechnology domestic manufacturers. The water heater "Termeks" 15 liters, the instructions for use of which are strictly followed (the boiler is grounded), will last longer than their foreign counterparts.
Expert Reviews
Professionals in the field of savingswater heaters note that there is no significant difference between foreign and domestic manufacturers. Machinery manufactured in China, Korea, which was acquired in a non-specialized shop, is of poor quality. These heaters may have poor thermal insulation or less than their counterparts, the thickness of the tank.
Poor quality components become a frequent cause of failure.
Водонагреватель накопительный 15 литров "Ariston", "Electrolux", "Bosch", "Combustion" are noted by experts as the most purchased. However, if they are connected incorrectly and if the requirements of the manufacturer’s instructions are not fulfilled, they will not work for a long time.
Even the highest quality boiler will needservice once a year. Cleaning the tank and replacing the magnesium anode are mandatory conditions for the manufacturer to fulfill its warranty obligations.
Cost
Согласно проведенным исследованиям, высокая cost is not always a guarantee of quality. The most expensive are German, Swiss, French, Polish and Turkish boilers. Their price sometimes reaches $ 240.
However, few people are interested in the assembly country.For example, the water heater "Ariston" 15 liters, reviews of the cost of which attribute it to the mainstream segment, is surprising. After all, this device often has an assembly in Russia. And its high cost is explained only by the brand name, not the cost price.
But the relatively inexpensive boiler of the Italian configuration "Fer" (about $ 70) is quite cheap thanks to the assembly in China.
Installation
Install a water heater of 15 liters prettynot difficult. It has a small weight. Depending on the configuration, it is attached above or under the sink / wash basin. He can be on the sidelines. It is attached to the wall with dowels. Tees are installed in the inlet pipes, a cutting is done. 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 check 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 goes normally, the boiler is installed correctly.
Electric power can be done through a socket or automatic.
Having familiarized with such device aswater 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 significantly prolong the service life of the boiler.
