Radiator water heating, or, as it is called, the battery is familiar to everyone. It is this device creates in our homes warm in winter. Progress does not stand still, and to replace cast-iron monster of Soviet times has come a new generation - aluminum bimetal and steel panel radiators. Radiators steel panel radiators of this type are made of two steel plates with thickness 1,25-1,5 mm, in which stamped grooves, forming reservoirs and connecting channels. The plates are connected by welding. The height of the steel radiators - 200, 300, 400, 500, 600 and 900 mm, and length - from 400 mm to 3 m. A large area of ??panels and the presence of fins in interpanel space provides a high level of radiant heat that increases comfort heating. Steel radiators are designed for pressures up to 10 atmospheres, but if they will air, they will start korrozirovat, so pour the water out of them more than two weeks, you should not: they began the process of corrosion is impossible to stop. Install steel panel radiators in the central heating system is not recommended due to the fact that in the case of water hammer (pressure greater than 13 atmospheres) radiator can swell up to form the barrel, or break, and if with risers for the summer blends coolant (water) and the radiator is not overlaps. If the coolant (water) that flows through the radiator is not entirely clear, in the bottom of the deposited mud (there is a "siltation" sink). Advantages: - Low price - high heat Disadvantages: - fear drain coolant - Low operating pressure Aluminium sectional radiators Sectional radiators made of aluminum alloys - elegant, light, high heat - are the most popular on the Russian market. Radiators of this type are delivered by our company with such well-known companies as GLOBAL. The length of the radiator (and thus their power) can easily pick up, changing the number of sections used. Given the wide range of center distance of 300, 350, 400, 500.600, 700 and 800 can always choose the configuration that meets a variety of architectural features of the premises (the width of openings, piers, the height of niches, etc.). Each section has an upper and lower reservoirs, connected by vertical channel, and fins that increase heat transfer. Due to the high thermal conductivity of aluminum, these radiators have a maximum heat output (at center distance of 500 mm, it is about 200 watts) and the optimal price, but the aluminum radiators have one drawback - it is an electrochemical reaction of aluminum oxide coating the inner walls of the radiator with alkaline and acid coolants central heating systems. The advantages of aluminum radiators can be attributed the greatest heat output of all existing types of radiators. Advantages: - the best price - high heat - a large area of ??the cross-section tubes mezhkollektornyh - elegant design - lightweight sections - high working pressure Disadvantages: - possibility of corrosion in low-quality coolant in central heating radiators, bimetallic Bimetallic sectional radiators successfully combine the best properties of aluminum sectional and tubular steel radiators: strength (withstands pressure of up to 40-50 atmospheres), durability (service life - up to 20 years) and high levels of heat in combination with modern design. As the name implies, the bimetal radiator are two metals - steel and aluminum. For example, in a model of Global Style everything that comes into contact with the coolant (water) is completely made of steel, which allowed to avoid contact with the aluminum component of the coolant and increase the initial operating parameters (pressure 35 atmospheres, with coolant temperature 110 ° C). Steel tubes keep the pressure and resist corrosion, and aluminum transfers heat faster than air. Bimetal radiators Global differ from similar models of the following parameters: working pressure to 35 atmospheres of highly reliable silicone gasket between the sections of impeccable quality color more than counterparts in diameter mezhkollektornoy Crimp tube steel tubes under high pressure in the casting process creates in their pre-tensions, which allow Firstly, Expander resist water pressure and, secondly, to compensate for the difference of the temperature deformation of steel and aluminum and retain the heat transfer constant. Collectors sections are simple in shape and do not have pockets, where they could be formed air pockets. Small diameter channels (aluminum radiators so difficult to obtain) reduces to 2-3 times the volume of coolant. Therefore, the bimetal radiator quickly respond to the thermostat and provides a comfortable mode of heating. To seal the joints between the sections of the radiators used highly reliable silicone gaskets. Similarly constructed grooves for placement of these rings ensure tightness of joints, regardless of the efforts of the contraction section. Institute of Plumbers conducts studies of bimetallic radiators since 1995 During this time, experts have seen in the high consumer properties of radiators and their longevity. We can say that the higher cost of bimetallic radiators (15-20% more expensive than aluminum) is completely compensated higher reliability. And if a city apartment of 100 m2 you will have to shell out the extra $ 100-300, it is quite a small fee for a feeling of complete confidence in the reliability of your radiators. Advantages: - High heat (170 to 200 watts for center distance 500 mm) - High operating pressure (up to 35 atmospheres) - elegant design - the neutrality of the chemical composition of the coolant - a small amount of coolant Disadvantages: - high price (15 - 20% more expensive than aluminum radiators) - less than the aluminum radiator flow section area mezhkollektornyh tubes
