Heating system

In Russia we can afford to do many things in an ineffective way.

We don't worry too much about spending resources because we think we have plenty to spare.

Among such things though there is the one that is very special.
It's our heating system.

We have to heat up a lot of buildings, with huge square, and we have do it for a long period of time, like 6-10 months per year.

Another factor is that in many cases people lives crucially depend on that system.
If during the winter the building gets frozen, people wouldn't be able to live in it until next summer.

The system consist of a few parts.
The first one is a plant that produces hot liquid.

Usually it has several redundant sources for making energy, usually it is piped natural gas + reservoirs with oil or store for coal.

It can work and produce warm for a long time autonomously.
Also, for redundancy there are several such plants, so if one of them stops, others can do its work.

After warming in such a plant hot liquid pumps in to well-insulated pipes.

and goes to the buildings and homes.
Despite the insulation, those pipes are pretty warm, so many animals like them, and vuild their nests above them.

Inside the room we have radiators like this one:

We have them in each room under the window.

The radiator is a very simple devices with a tap to adjust it's temperature.
The system is good in general, redundant and cheap.

I pay about 50$ a month for that heating, which is much cheaper than producing  heat with a small gas radiator or wood stove (I do that at my country house and it 10 times more expensive).

Our people love to have hot temperature inside houses, usually it 26+C inside, and since I live in the block apartment it happens that I never open taps of radiators in my rooms, because I have enough heats from neighbors.
