Many, who are planning to start the repair and renovation of the heating system, They set themselves the same question. Prefer the old cast-iron battery, or choose new and modern bimetallic radiators?
To a more detailed approach to the task, We need to fully explore the advantages and disadvantages of cast iron and bimetallic battery. Analysis of the properties will take place on three criteria: heat irradiation, reliability during operation, able to get savings, by using a specific type of battery.
heat irradiation
Many people know about the amazing properties of iron to transfer the thermal spectrum. After all, scientists unanimously recognized cast the most favorable material for human. In other words, iron using absolutely harmless.
If we compare the rate of heat loss, then this indicator iron batteries is considerably inferior bimetallic competitors when heated premises. However, we must not forget this figure, as maintaining the heat during cooling. Here on this indicator superiority iron batteries obvious. If the house is used heat input from the same source, usually, boiler, thanks to the presence of iron will not happen fast battery, and slow cooling. It is for this reason that in homes, where small children live, it is recommended to put cast-iron battery.
However, we must not forget this important point. The fact, that iron is unable to quickly change the temperature. In this regard, to maintain proper temperature requires uninterrupted operation of the boiler. Otherwise, there will be a full house cooling. In order to return him to normal temperature conditions require a lot of time, because it will warm up very slowly.
serviceability
Many have probably heard, that iron is very brittle material. To display the cast iron radiator down enough to hit him only slightly. It is worth noting, that if the damaged section, then repair it is not subject to. Besides, as the use of cast-iron battery, its interior walls there is the formation of scale. A scale can lead to a significant reduction of heat transfer.
In all the characteristics of bimetallic radiators, even in a few years, will be at the same level. Besides, they are characterized by high reliability, and the blows to the radiators Bimetallic survive with dignity.
Saving
Due to the high thermal inertia of the iron in the operating mode of the system is impossible to quickly change. If your system has a clever technique, the savings are not so great. After complete control will be automatic, and she will be guided by indicators of temperature on the street. And here at bimetallic radiators low thermal inertia. It is this low inertia with automatic control of the boiler provides good savings. worth considering, that the automatic operation parameters vary depending on the weather conditions. These experiments were confirmed both theoretically, and experimentally.
Cast-iron batteries of the above criteria significantly lose more modern bimetallic radiators. Besides, at the cost of higher iron, and the short lifespan. But there are some positive thing when using cast-iron battery. After all, these batteries are widely used in buildings, which are intended to be in their children.
