Batteries, or, as they are still called, radiators are a very fundamental element of the heating system. The heat in the room, comfort, cost savings, and interior design depends on the right choice. First you need to pay attention to the durability, reliability and safety of radiators.
It will be more fundamental how the radiators of heating the premises are done and, of course, an important aspect is the price. Still not so long ago, the main type of household heating devices were cast -iron radiators. Now metal radiators have the most conflicting reviews. In fact, cast -iron radiators are endowed with a number of advantages. They have the highest corrosion resistance. This advantage is justified by the property of cast iron. The surface covers, so named, dry rust and this actually eliminates subsequent corrosion. The poor quality of the coolant does not influence cast iron.
Well, if you are interested in the woven grid. Only there you will find high -quality woven nets at reasonable prices and with quick delivery.
Hard particles (stones, small pieces of rust, etc.D.), which are part of it, cannot significantly destroy the inner surface of the radiator, but, as it should, abrasive wear of an insignificant. One of the reasons that ensure the durability of metal radiators is significant thicknesses of their walls. Metal radiators are characterized by the highest heat accumulating capacity and thermal inertia. Another advantage of metal radiators — they can be operated for a rather long period without cleaning. Such an opportunity is ensured by a huge internal section. The radiators have a fairly long service life. 50-year period of use for a metal radiator is not a limit. And when operating in a system with a high-quality coolant, then without special troubles will be able to achieve a 100-year experience.
But today there is no impeccable radiator and, in addition to positive features, there are negative. One of these shortcomings of metal radiators can be considered their significant weight. In addition that this delivers significant difficulties during transportation and installation, there are problems with fastening if the walls are not strong enough (for example, drywall). For such cases, radiators are equipped with special legs for installation on the floor. Cast iron radiators lose their «competitors» in strength. Hydraulic strokes can be dangerous for them. The best pressure for them should not exceed15 atm.
