Of course, if the central heating radiators are fried so that you have to open the windows at -20, then probably the smart home system won't help much here, you just need to go and figure out why the heating system is set up like this in general. But if heat meters are installed, then of course it will be useful to somehow track heat consumption and perhaps even manage these radiators, make them less heated, and thus also save heat and, accordingly, money. But in fact, there were clever people who realized that in this case you can simply block the central radiators and simply heat your apartment at the expense of neighbors, in houses in apartments, and of course in many houses now, even if heat meters are installed, they are simply not used for this reason.

But if you still think about the environment and somehow understand that even if you saved money in your apartment, the total bill will still be smaller and of course the apartment will be more comfortable than just opening the windows in winter and ventilating. In new homes, it often also conducts an examination to either increase or lower the energy efficiency coefficient of the house, and of course if it is increased, then in principle more heat is put on the house, respectively, it will warm more, but again it turns out that the cost of expenses will be higher and you will still need to pay. But if really in the house for example not very good Windows or in general the house itself is built on enough designed for a lower temperature, then of course to freeze, too, like, and not really want to.

According to the standards, of course, it is very strange that it is generally supposed to be 18 degrees there, this is the minimum norm in general there is 20-22 degrees, but in reality, of course, for example, I am not at all comfortable at this temperature, I basically have a temperature of 26 degrees set, and at this temperature, in principle, you can be quite comfortable.

And for example, I also did it so that I automatically lowered the heating power in the rooms at night and did it first and 3 degrees less, that is, I set 23 degrees then it seemed to me that it was still cold and waking up from the cold in the middle of the night was not very pleasant and falling asleep was not very pleasant and 25, but in the end I came to the conclusion that all this is not really worth the cost and time writing all the algorithms is tricky, it's easier to put one temperature stable not very high not very low, and in this way it will still be more comfortable there will be fewer differences there will be less time to work the heater, if it is additionally used like mine, then in general it is much easier, but again it is possible if you use a multi-tariff, multi-tariff grid electricity, then of course you can also save money in this way, for example, if you still it is possible, for example, at night or in the morning when the temperature needs to be raised, then until 7 am you can basically heat it a little higher with the help of these radiators, and then, by inertia, during the day it will just gradually cool down and keep the temperature in the room a little lower.

Thus, of course, you can also save quite well, because the consumption of course will still be quite large for electricity. But in fact, my central heating radiators do not heat very much, how many degrees exactly will be if only I have not checked them for a long time, but I think that about 20 degrees will probably be a stable temperature, but if for example I warm up to 26, then of course the electricity consumption is quite large, but for a year in on average, that is, including the winter itself and the coldest days, when almost this radiator works at full capacity and constantly, and in the off-season when it is also necessary to warm up the room, and the central heating is already turned off, in this case, I get only about 1000 rubles a year for one room, which in principle is not so much.

For example, I also constantly thought that it is possible to replace the central heating radiator with a more powerful one, so that the heat transfer is higher,or replace the windows with more modern and warmer ones. But in fact, there is not much sense because in fact the cost of this replacement will be maybe even 100 thousand rubles, but if you just spend this money on payment, then it will last for many, many years, but either you can even put this money, if you suddenly have it, just to the bank, and with interest pay, and even stay will be 3 thousand, so that, after paying for all the energy spent on heating.

Well, of course, it doesn't make much sense to insulate most of them, because you still need an influx of fresh air, otherwise you will have to make additional different valves or breezers or some other ventilation systems to come up with something that will also cost money and also need to be managed somehow, so by and large there is some-a balance that can be monitored and measured using experiments, for example, simply turn off everything and see how fast the temperature will change, for example, the temperature in the apartment will fall, if you also measure, for example, how I do CO2 there, then you can also see that if the ventilation works well, then the CO2 is kept at a good level and you do not need to open windows all the time separately and think about how to do it automatically in some way, open these windows, and thus of course it is much easier to more comfortable temperature and climate, and the air in the rooms.

Well, in order to determine what heat losses and what speed of ventilation, of course, you can put some kind of meter on the ventilation and see how much air outflow is going on, but it certainly depends on the temperature outside, the draft of this ventilation and therefore it will be visible to experiment several times, and there may be different ventilation channels there are several of them in the apartment, especially in the house, and of course you can simply conduct an experiment to heat it up to some temperature and see how fast it will cool down.

I get it so that during frosts when it was minus 20 outside, I get it so that for about half an hour the room heats up from the radiator and for about an hour it cools down. In principle, such a cycle is very comfortable, that is, the very switching of the radiator and the clicking of the outlet is also not annoying, and in principle, in this way, you can also understand how effectively the ventilation works and the air flow in the apartment in general.

Often they also use other sources of heating - these are the radiators themselves, additional electric and convectors, and also use underfloor heating to control, the underfloor heating after all measures its temperature and not the temperature in the room most often, and even if the remote thermostat also has a function of measuring the temperature in the room, but since it is located quite close to the if they usually put it low, then it will certainly show closer to the floor and not at the level where people usually are.

Well, also the radiators themselves if they use some kind of temperature controller installed, then it is located quite close to the city, and the temperature on it will be very high, not really the one that is currently the air temperature in the room.

Well, if you generally want to use some additional sources, then you can just turn on different equipment there, for example, a computer gives a lot of heat, a TV, use a kettle, or even some other light, turn on different light bulbs, of course it will not only be warm and light, but it will also be fun.

Automation in a smart home should be useful and create additional comfort, but sometimes everything goes wrong… The reasons for this, and how to configure everything, see on my channel.
