When it comes to the heating system when carrying out repairs in the home, the question often arises for the owners: how to choose heating radiators? And it is asked for a reason, because the market now offers a huge variety of shapes, materials and the appearance of devices, which cannot but put a simple layman in a dead end.
How to choose heating radiators
If you do not have a sufficient level of knowledge regarding heating systems, then for the right choice you need to pay attention to the operating conditions that you currently have, as well as the thermal power of the devices, design and maintenance requirements. Let's look at the requirements that apply to the operating conditions of radiators. The main parameters that need to be considered are the following: operating pressure used in the heating system, purity and temperature of the coolant. These parameters are very important when using different types of radiators. And here you must consider the place where they will be used. For example, choosing radiators, heating for a private house is the main goal of which, you can proceed from the fact that a high-quality coolant will be used, the pressure of which will be about 3 atmospheres, and the temperature - no more than 95 degrees. When operating in central heating conditions are completely different, so you should consider this. To decide which heating radiator to choose, you need to study the currently existing types.
Cast Iron Radiators
This type is used very widely. Cast iron radiators have a large heat capacity, even after lowering the temperature of the coolant they will be hot for a long time. They are not afraid of the low quality of the coolant, the temperature of which can be up to 130 degrees, the maximum working pressure - up to 15 atmospheres. They also have disadvantages. Hydraulic shocks are not beneficial for such radiators ; some models may require additional painting and preliminary drawing. Sometimes a large drawback becomes a large heat capacity. The most popular brands are such as GuRaTec, Viadrus.
Aluminum radiators
They have excellent thermal conductivity, insignificant thermal inertia, due to which they can be effectively used to stabilize the necessary thermal conditions in the room. The appearance of such radiators is very attractive. They are made in normal and reinforced versions. For central heating systems, the latter are preferable. When deciding how to choose heating radiators, you should also know about the shortcomings of aluminum: they are very sensitive to the purity of the coolant and the level of its acidity, electromechanical corrosion can occur at the junction with the steel pipe. Due to the tendency to gas, air jams may appear in the heating system. The most popular brands are the following: Global, Rifar, Elegance.
Bimetal radiators
Such devices consist of a steel pipe and an aluminum shell. In appearance, they are comparable to those discussed above, and their design features relieve them of such shortcomings as high demands on the coolant and hydraulic shocks. Such radiators are quite appropriate to use in high-rise buildings. But they also have certain disadvantages: a lower level of thermal power, due to the small internal cross section, high cost due to the complex design. The most popular brands are Rifar and Sira.
Steel panel radiators
They can be installed in any heating system. They are afraid of low quality coolant, have low thermal inertia, due to which it is possible to effectively regulate and maintain the temperature in the room. Disadvantages: there should not be an excess of oxygen in the heating system, radiators do not allow adding sections. The most popular brands are Purmo, Kermi.
Now you know how to choose heating radiators.
