So as not to run into problems before startingheating season, such as leaking a worn radiator, it is worthwhile to take care now to choose a suitable heating appliance. We have collected the most current recommendations, which, we are sure, will help you to avoid trouble and not to freeze.
A photo: Getty Images Bimetallic radiators have recently become increasingly popular, because they look much more attractive than heavy cast iron and much more reliable than their aluminum counterparts. This type of radiator is made of steel with aluminum, which has a high thermal conductivity and perfectly warms the room. Moreover, the distribution of air masses occurs by convection. The radiator looks modern and concise, it will neatly fit into the interior of any room. In addition, it will last at least 20 years. The steel collector prevents the occurrence of corrosion, is resistant to pressure drops, prevents aluminum from contact with the coolant, protecting the material from destruction. First, decide which model you need. Many bimetallic radiators consist of sections. Usually there is an even number of such elements, the joints between which have hermetic gaskets fixed by nipples. The advantage of this model is that you can always attach or remove the required number of sections. But there are still monolithic structures that can cope with pressures up to 100 atmospheres. Such models are more expensive, but if there are powerful hydraulic shocks in your centralized network, then you should give preference to these radiators. Another important indicator is the material from which the radiators are made. For example, there are models made entirely on the basis of a steel framework, or those that have steel-reinforced channels. Experts believe that the first type of radiator is more reliable, but in semi-metallic devices, for example, high heat transfer. To choose a really high-quality model, pay attention to the price. After all, for the manufacture of cheap options, less steel and aluminum are taken, by construction they are simpler, and the coloring of such devices is usually made according to the budget option. To find out exactly how many sections should be in the radiator, you need to make a simple calculation. Power models can vary from 160 watts to 2.4 kilowatts, and it all depends, of course, on the area that must be heated. If, for example, you have ceilings of 250-270 meters in a room, one wall faces the street and there is another window, then 100 watts will be enough to heat one square meter. In a room with ceilings of 250-270 meters, where there is one window, but already two walls face the street, for heating one square meter it is necessary to choose 120 watts. In a room with standard ceilings, where there are two windows and two walls facing the street, 130 watts will be needed to heat one square meter. For a more accurate calculation it is necessary to multiply the area of the room by the power index and the correction factor (1.1). For example: 19 square meters. m (area) x 100 watts x 1.1 = 2090 watts. Now you need to look into the passport of the radiator and find out how much heat one section has. So you will understand how many sections will be enough to heat your room.
Important information
Alexander Krasavin, commodity specialistLeroy Merlin's offer tells how to get the most out of your heating system: 1) Install temperature regulators on the radiators to maintain comfortable conditions in the room. Please note that without thermostats, the radiator will heat up to the level of the coolant, which will burn oxygen and, as a result, make the room stuffy and give you headaches. In a stuffy room, you have to open the windows, which means losing precious heat, which you pay for out of your pocket. Installing a thermostat will help you save money - you will pay exactly for the amount of heat you used. 2) Do not cover the radiators with thick curtains. They limit the flow of heat into the room. 3) To prevent heat leakage, do not keep the window constantly open, it is better to arrange cross-ventilation for a while. This way you will fill the room with fresh air, but there will be no sharp drop in temperature.
