Batteries have entered our lives for a long time. Two main options were originally presented — cast -iron and steel. Cast iron batteries have been more popular, which have a number of significant advantages compared to the second option. Cast iron radiators retain heat longer, are much less susceptible to all kinds of deposits, heated much better. Along with a weighty number of advantages, there are a number of significant drawbacks. These include the moment that they are heated well if the coolant in the heating system has a fairly high temperature. Such batteries warm up quite slowly, and their thermal inertia was high. However, over time, aluminum radiators appeared on the market. Aluminum alloys are endowed with structural strength and a fairly high level of thermal conductivity. Thanks to this, it becomes possible to manufacture quite compact radiators from this material. In modern designs, the principle of heating thermal radiation, as well as convection, is combined. A small amount of circulating carrier, low thermal inertia makes it possible to significantly save money estimated for fuel costs. In addition, only aluminum radiators are capable of working with low -temperature operating mode of the heating system.
