It is strongly recommended to monitor radiators before the winter season. If it is found that they are worn out in order, that is, rusty streaks or stains have appeared, then this will turn out to be a serious reason for their removal and installation of new versions.
If you need extremely heat-conducting radiators, which are still excellent in their low cost and relatively long service life, it is better to choose cast iron and aluminum versions.
The former are highly rated for increased durability, which is up to 50 yearsif the heater is operated in the private sector, where softened water is used as a heat carrier. In the urban sector, the service life of cast iron batteries is slightly less (up to a quarter of a century), but this is due to the fact that in the city often a coolant with an increased amount of oxygen is used, which causes accelerated corrosion of cast iron or become. But even this period (25 years) is considered quite good, since not all radiators can serve that long!
If we take into account that the power of each section for cast-iron analogs reaches 80-160 W, then the room, if the radiator is assembled from many sections, will be able to warm up quickly enough. Especially the versions with a three-finger design, that is, up to three adult fingers can easily pass between the sections, while the two-finger versions are slightly cheaper.
There are drawbacks to cast iron counterparts - not always modern appearance and somewhat slow heating.
These disadvantages are devoid of aluminum radiators, which have an extremely low level of thermal inertia. To be more precise in this matter, then aluminum versions have a power of each section up to 212 W. In this case, the heating of any enclosed space will occur very quickly!
The strength characteristics of aluminum analogs in theory turn out to be very large - they are able to withstand extreme pressure up to 12 atmospheres, but in reality it is better not to risk it and not install it in the DSP system, in which strong water hammers are frequent. But in rural areas, where a heating boiler is operating, which releases the coolant with a force of no more than 7 atmospheres, these versions of radiators turn out to be an ideal choice - they serve for a long time (up to 15 years), warm up the room faster and have a much better appearance.
Also, copper radiators, valuable in that they can easily withstand coolant temperatures up to 140 degrees and pressure over 25 atmospheres, will also be a good solution..
But the main advantage of the copper versions is that they can easily operate on an alternative coolant in the form of antifreeze. In the latter case, if you need to leave the rural house for a long time in frosty temperatures, you will not have to drain the antifreeze at all, since it does not freeze down to minus 40 degrees. The disadvantage of copper analogs is the possibility of failure as a result of electrochemical corrosion if there are copper fittings in the heating system. But due to the fact that stainless steel is predominantly used, then copper batteries last up to 50 years.
