Heat dissipation cast iron radiators - not only the dignity of the heating system

Description Radiator coolant

in homes and apartments from autumn to late spring is not possible to do without heating devices, devices that heat the room or other external medium heat coolants submitted to it.Most often acts as a coolant heated water.

And then just remember the familiar childhood battery sectional cast iron radiators, familiar to all inhabitants of the city, town and other buildings connected to district heating systems.They are made such radiators injection molding methods of gray cast iron.

goal heating systems, the choice is often cast iron radiators, the technical characteristics which ensure their high operational reliability.They withstand the internal pressure reaches fifteen (!) Atmospheres.But, among other things, the material is sufficiently resistant to the corrosive effects of the heat carrier.Therefore, the central system is used to ensure heat is far from perfect.

heated heat transfer fluid (water) from the Centrals by pipe supplied and distributed among consumers.In this case the coolant (and this is acknowledged even by the producers themselves) often has high abrasive and aggressive.

Cast iron radiators are not sensitive to the media that, in view of the withstand pressure, allows their use with steam and coolant.This dramatically increases the power output section of cast iron radiators.

Main features cast iron radiators

Besides high resistance to abrasive and corrosive effects of the heat carrier, distinguishing cast iron radiators heating characteristics provide long-term (at least fifty years) periods of service and attitude of heat transfer and convection at a level of approximately two toone.And the possibility of the battery set of sections of cast iron radiators, allows you to adjust the amount of heat given off.

Thus, the weight of the cast iron radiator sections remains high, reaching five and a half kilograms.Which, given the recommended length of the entire battery (not less than 75% of the width of the window opening), determines its rather high overall weight.

inside apartment trend supplying heating equipment systems, ensure regulatory and accounting of heat consumption, thermostats, regulators and valves makes it necessary to use special filters installed in the devices themselves and control nodes.

The same filters are needed in the risers between floors.Installing such equipment also leads to the need for their annual cleaning between working heating seasons.

On weight iron radiator affect its design.Habitual two column sections, but the industry also produces trehkolonnye section.Many producers, especially foreign ones, have established a production of such sections, using a high consumer interest in retro style.These radiators can be applied coating that makes their color not binding.

recommendations on registration and location of cast iron radiators in the room

By the way, there are recommendations to methods and materials used for painting assembled in battery cast iron radiators.After properly selected coatings can reduce power cast iron radiator to ten per cent of the declared by the manufacturer.

Besides the correct selection of the coating material, the heat flow from the battery can be increased by directing it from zaradiatornogo radiation into the room using a Heat Reflector on the wall, to which is attached the battery.

As is known, the heating system for the payment of the house is quite complex consideration of factors and building coefficients, pressure and coolant temperature, etc.But roughly, for the standard sections of cast iron radiators, Venue to 0.6 meters, heat flow claimed about 125 watts.

provides heat area cast iron radiator sections is considered taking into account the length, height, depth, etc.and can be up to one (at the previously specified height) to 0.2 square meters.Accordingly, a set of five sections amount to little more than one square meter, based on transition elements.

In conclusion, it should be noted that the installation of the battery affect its effective use and heat dissipation.Current guidelines stipulate a minimum distance from the wall (refer to three) of the sill (12 cm) to the floor (15 cm).These recommendations take into account the optimal conditions of work and heat.
