Indirect heating stainless steel boilers

By and large, the indirect heating system - an additional circuit that heats water, which is placed in an additional container. It is called a boiler. It helps to heat water to very high temperatures. Due to the fact that there is no direct contact between the consumed hot water and the coolant, it is called indirect.

High efficiency and thermal insulation of the tank can reduce the consumption of electricity boiler. And in comparison with the heating boiler it will be mere pennies.

The final choice should be made after getting acquainted with all the features of the room in which the installation is planned. It is necessary to take into account all the conditions of its use. Now there are many different options offered.

• Wall-mounted boiler. This device is attached to the wall at a low height. The only note to the installation. The wall on which the boiler is placed, should be quite strong.
• Floor boiler. Needs a separate room for installation.
• Vertical boiler. The most popular type. Due to the fact that it is limited in size, it is ideal for installation in offices and apartments.
• Horizontal boiler. It is distinguished by its large capacity, so the scope of its application has become enterprises. It does not need additional pumps to keep the water at the required level.
• Boiler with a coil. It all depends on the number of circuits in it. One circuit is more popular. It is such boilers more often come with boilers. If there are two circuits, the water intake for the boiler and return for consumers occurs simultaneously.
• Boiler with recirculation. An additional inlet to the tank is needed to provide recirculation.
• Boiler "tank in tank". These are two tanks placed one inside the other. In the small tank, which is inside - water. The water needs to be heated. In the large outer tank - the coolant, which acts as the water from the boiler. Such boilers have a good efficiency of operation with running water. Also to its advantages can be attributed its compactness.
• Accumulation boiler. In addition to heating water, keeps the selected temperature mode.
• Combined boiler. It has a heating element or a gas boiler. You can try different types of fuel, but the price tag on such a pleasure is quite high.

More well-known manufacturers represented in the Russian market:

1. ACV (Belgium). Produces the whole range. Boilers of this producer have better insulation than others, they are efficient and compact.
2. Gorenje. The low price with not bad quality of assembling.
3. Nibe (Sweden). Beautiful ceramic heaters.
4. Protherm (Czech Republic). Clear control and a steel tank.
5. Valliant. High-speed water heating.
6. STEELSUN (Turkey). Not the highest quality, with a very low price.

The choice is quite wide. When choosing, you should pay attention not only to the heating system, but also to the materials used, or rather their compliance with sanitary norms, and to the availability and ease of operation.

Boilers of stainless steel, unlike enameled ones, allow heating water up to 90º C. Diluting the hot liquid to a temperature of 45º C makes it possible to double the capacity of the tank. At the same time, such a boiler takes up less space and saves energy for heating, compared with counterparts made of other materials.

The prices for this type of products start from 40 thousand. For this money you can become the owner of the apparatus of the company STEELSUN (Turkey). But do not hurry to stop at them your choice, because the quality of assembly is not at the highest level, and there is a risk of failure of its individual elements.

Stainless company Nibe (Sweden) is in a price segment from 60 to 170 thousand rubles. And this is not the limit, but you can pick up a good model for not very much money.

A few recommendations on the selection of such equipment.

• It makes sense to buy such a device if your water flow rate is more than 1.5 liters/minute.
• It is necessary to make a power calculation. Whether the boiler is able to heat both the room and the water.
• The material of the inner part of the heater. It should not be afraid of water. Protection against rust is simply necessary.
• Material insulation is recommended mineral wool or polyurethane foam.
• Select the size of the boiler, so that you do not have to make repairs under it.
• Familiarize yourself with the warranty on the device, its term and what the manufacturer includes in this concept.
• Do not buy from a dubious manufacturer. Maybe he does not have service centers in Russia.

If you take advantage of all the rules and recommendations, you can be sure that a stainless steel indirect water heater is an excellent choice for many tasks.
