Cast iron radiators: all “pros” and “minuses”.
You decided to purchase cast iron radiators? Before doing this, find out about them all. Like any other device, cast -iron radiators have a number of advantages, but at the same time they are not devoid of some disadvantages.
The advantages of cast -iron radiators include the following factors:
1. the ability to use cast -iron radiators in open systems;
2. From cast -iron heating batteries, water can be drained as often as you will need;
3. cast iron is resistant to corrosion – in other words, various suspensions contained in the water of the coolant are not terrible of cast -iron heating batteries;
4. cast iron has low thermal conductivity;
5. Cast iron heating batteries tolerate the estimated temperature and pressure characteristic of Russian central heating networks. Today on sale you can find models that are designed for working pressure of 9-12 atmospheres (the maximum temperature of the coolant is 110ºС).
We have listed the advantages of cast -iron radiators. Now let’s say a few words and about the shortcomings of cast -iron heating batteries.
6. Cast iron radiators, due to the fragile structure of the material, do not tolerate hydraulic blows too well (they often occur when starting pumping equipment);
7. Cast iron radiators have great thermal inertia. Thermostatic valves are installed on modern heating batteries. Their task is to automatically change the flow rate of the coolant depending on the temperature of the room. Cast iron radiators, after closing the valve, cool for a long time and heat up for a long time after it is opened.
Now you know everything about the pros and cons of cast -iron heating batteries. You just have to make sure that their parameters are suitable for specifically your conditions. Remember – the most important thing is to use cast -iron radiators in systems with those parameters for which they are intended.
