An indirect heating boiler is an electrical device (barrel of water) that heats water in several ways:

1. Water heating is carried out using a heating element (boiler principle);
2. The water is heated by the heating system. Built-in heat exchangers can be connected to gas, electric, solid fuel boilers. Water heating can even occur due to solar energy.

Tank capacity 100 - 1000 liters.

Indirect heating is the heating of water in a boiler from two sources that are independent of each other.

• The first way is electric, with the help of a heating element, according to the principle of an electric kettle.
• The second heating option is from the heating system: gas, electric, solid fuel boilers, centralized heating system or solar systems.

Water in the heating system acts as a heat carrier, which gives off part of the heat to the water in the tank of the indirect heating boiler. Thus, the water is heated to the desired temperature, and the user has the ability to adjust the level of its heating. A kind of circulation in the system - boiler - heat exchanger - pipeline - boiler.

The second way to operate an indirect heating boiler is to electrically heat water using a heating element.

TM RODA convectors are produced in capacities from 0.5 kW to 2.5 kW, where 1 kW is designed to heat an area of 10 sq.m. But along with this, it would be reasonable to take into account the material and thickness of the walls, the height of the ceilings, the number of windows and doorways. For a more accurate selection of a convector for your room, we recommend contacting qualified specialists from manufacturers.

The methods by which the convector is adjusted are carried out in two ways:

1. Mechanical way - Mechanical convectors . It is considered inexpensive and practical, temperature control with a deviation of one or two degrees.
2. Electronic method - Electronic convectors . More precise temperature control. Can be programmed to automatically turn off after reaching the set temperature. Such convectors are more modern, but more expensive.

Electric convectors have a maximum efficiency of 90%. All consumed electricity is converted into heat. The convector is one of the most economical types of equipment.

Electric convectors have a maximum efficiency (coefficient of performance) - from 90%. All consumed electricity is converted into heat. Heat spreads throughout the room and heats it up as quickly as possible.

Which convectors are the most economical ? An electric convector is one of the most economical types of equipment.

Often people are frightened by the sounds that an electric convector makes during its operation. In most cases, there is nothing to worry about. If an electric convector cracks , then the main reason may be overheating of the metal and deformation of the body due to this. The same sounds are heard when it is cooled.

The second reason may be the heating element, which makes quiet but unpleasant sounds. In this case, you need to solve the problem by contacting service specialists.

The price of aluminum radiators of 10 sections is from 2199 UAH. The cost of the section is from 220 UAH.

Aluminum radiators consist of sections, which makes it possible to divide them by adding sections or, conversely, take away, select a radiator for a room of any size and complexity.

The power of one section of an aluminum radiator at delta t=70C from 180 W - 183 W

The calculation of aluminum radiators by the number of sections through the standard formula is as follows: multiply the area of the room by 100 W (on average) and divide by the power of the radiator section . However, this formula is not entirely correct due to the fact that it is necessary to take into account the material and thickness of the walls, the height of the ceilings, the number of windows and doors. In order to select aluminum radiators in detail and accurately calculate the number of sections, it is recommended to contact the manufacturer's specialists.

Aluminum heatsinks are manufactured by high quality aluminum alloy die casting with silicon addition. They consist of sections that can be added or subtracted, thus selecting the radiator power for any area and complexity of the room.

1. Aluminum - a universal heating option due to the fact that the coolant supply can be both from below and from above. This makes it possible to remake the old heating system for new radiators, create a project of any complexity for many rooms. The benefits are clearly:
   • weight;
   • they do not need to be painted over time, as they are covered with a special powder paint;
   • ease of maintenance due to its structure;
   • simple installation;
   • high efficiency and heat transfer;
   • affordable price.
2. Bimetal - they are not much different in appearance from aluminum. The main advantageous difference is that they withstand high pressure (40-50 atmospheres). This was made possible by a new method of injection molding and a mixed type of metal - aluminum and steel. Sections can be divided, added or removed - combined according to the area. High heat dissipation, modern look, light weight, ease of maintenance and installation, the ability to use in almost any room. Corrosion resistant. Service life 20 years.
3. Steel - these radiators have replaced cast iron as a more modern and improved replacement. What are the heating batteries of this type? Inside themselves, they are divided into three types depending on the number of panels: one, two or three, which are welded together with U-shaped ribs, which provide fast heat transfer. Unlike bimetal and aluminium, steel ones have side and bottom connections. This expands the range of design options for RODA heating systems .
