Batteries are rightfully given the main role in ensuring the heating of any room. To understand which radiators are best for an apartment, it is worth considering all the types that currently exist. To do this, you need to study the characteristics of all. The best option will be the one whose advantages will be manifested in the apartment or house as much as possible, and the disadvantages will not be able to prevent the effective operation of the system.
So, understanding the question of which radiators are best for an apartment, it is worth considering cast-iron sectional batteries. These heating elements are familiar to every Russian citizen. Once they were considered the best option. The main advantage of this solution is durability and strength. Their average service life is more than half a century. Such radiators perfectly tolerate the use of low-quality coolant, as well as the impact of aggressive environments. If pressure drops in the heating system may occur in your area, then such batteries are exactly the option that you require.
When deciding which radiators are best for an apartment, it’s worth understanding that thermal conductivity is considered to be the main characteristic of any material. This figure for cast iron is quite low, which is offset by a significant heat transfer area, as well as inertia. These radiators are indispensable in systems where the temperature of the coolant is very high. Modern processing methods allow the use of such elements in apartments made in a different design, which opens up ample opportunities for creative design of the room.
If you choose radiators in an apartment, then, of course, you will consider aluminum as an option. Such batteries are externally very attractive. However, they are absolutely not suitable for an apartment, since their design provides for the contact of aluminum with a coolant, which imposes quite definite requirements on the quality of chemical cleaning of the latter. The radiator fails due to the constant exposure to water with high acidity. Manufacturers took care of a variety of models. These devices are assembled in sections, so you can choose the required power level.
If we talk about which radiators are better for an apartment, then it is worth considering bimetallic. In them, only steel elements equipped with aluminum fins are in contact with the coolant, which can significantly increase heat transfer. And this avoids the problems that are inherent in products made entirely of aluminum.
You can also consider such an option as steel panel radiators. This type of equipment in our country is not very widespread, but its appearance did not go unnoticed. Structurally, this is a pair of sheets of high-carbon steel having pre-stamped channels along which the coolant moves. Corrosion resistance is ensured by degreasing and phosphate treatment. A small thickness with a high heat transfer area can significantly reduce the temperature of the coolant and its volume in the system. Low maximum pressure does not allow their use in central heating systems.
Now you understand that replacing a heating radiator in an apartment is a responsible and difficult process, so it is important to make the right choice.
