Batteries: choosing a heating radiator for an apartmentDecember 6, 2020
Batteries are an important part of the heating system in an apartment building. The room temperature does not only depend on how hot the water runs through the pipes. The quality of space heating depends on the design, material, power, and placement of heating radiators.
The extremely wide range of heating equipment can cause difficulties in choosing the right batteries. In order to find out which devices to give preference to, you will have to first study the features of existing types of batteries
Various types of heating appliances
There are several classifications of batteries.
Depending on the type of heat or energy carrier, they are divided into the following types:
- electric radiators;
- oil-powered radiators;
- water batteries.
Depending on the material of the battery, there are:
- cast iron;
- bimetallic ;
Depending on the design, heating radiators are divided into the following types
- sectional – due to the presence of separate sections, they allow you to adjust the size and power of the installed heating device;
- tubular – batteries designed specifically for a centralized heating system. They are an all-metal construction with a horizontal manifold and vertical pipes;
- panel – made of steel and even concrete. In the second case, such batteries are located inside the walls and transfer heat in the form of radiation;
- lamellar – have a core with lamellar ribs of thin metal sheets mounted on it, carry out convection-type heat exchange.
Types of batteries suitable for the apartment
Consider what types of radiators are suitable for a standard centralized heating system in an apartment building. It is characterized by the use of industrial water as a heat carrier, high working pressure and temperature. The characteristics of heating devices for an apartment must correspond to the features of this system. You can compare the parameters of devices from different materials in order to understand what types of them are suitable for your home, using the table.
Cast iron batteries
Classic radiators made of cast iron, despite the large number of modern analogues made from other materials, are not going to retire yet. Cast iron is resistant to corrosion and high temperatures, durable. Some manufacturers have changed the appearance of cast iron products for the better, decorating them with carvings and turning this device into a design element.
The efficiency and reliability of bimetallic radiators are achieved through a combination of two types of materials: steel and aluminum. The high thermal conductivity of aluminum makes it an excellent material for battery housing, and the strength of the steel makes it immune to pressure drops and corrosion processes.
It should be borne in mind that this type of heating devices has one feature: the steel begins to rust after the water in the system is drained. Models that use a copper core instead of a steel one are devoid of such a drawback.
Steel radiators can be panel, tubular, and sectional. The most popular is the first type due to the optimal combination of characteristics and cost. However, steel batteries are practically not used in multi-story buildings with centralized heating, since they are not intended for high-pressure systems.
Aluminum radiators have very attractive characteristics, including excellent heat transfer and low inertia, which allows you to quickly change the temperature in the room. But they are very demanding on the quality of the coolant, therefore, they are also not suitable for a centralized heating system.
Copper heating radiators
Copper batteries have a lot of advantages and only one disadvantage – very high cost. Their performance characteristics are impressive: copper radiators surpass all existing types in terms of efficiency, reliability, and durability, as well as resistance to corrosion and water hammer.
Installing copper radiators is expensive, not only because of the cost of the battery itself. They can only be connected to all metal pipes, which are also expensive. You can take advantage of the advantages of copper, and at the same time purchase a product at a more affordable price, if you choose a copper-aluminum radiator, the tubes of which are made of copper, and the fins are made of aluminum.
The newest type of heating device is plastic batteries. These products are easy to install, have a wide range of colors, and do not require additional maintenance. However, many apartment owners who are interested in the novelty will be disappointed: plastic radiators cannot be installed in a house with a centralized heating system. The reasons for this are the limitations of the maximum operating temperature and pressure, which should not exceed 80 degrees and 2 bar, respectively.
How to determine the required power of the heater
To make the apartment comfortable in winter, you need to choose the right radiator power. The power of a classic sectional device will depend on the number of sections. When calculating, the following factors must be taken into account:
- the material of the walls in the house is brick or concrete;
- area of rooms;
- the number of windows and their location on the cardinal points;
- number of exterior walls;
- quality of windows;
- use of screens for radiators.
