Summer energy — it’s time prepare for winter challenges. During seasonal maintenance campaigns, experts are trying to identify the weak points of the heating system to avoid unpleasant surprises in the new heating season. However, not all the thermal management fails to update and patch up over the summer, somewhere communication is chronically deprived of attention, which ultimately pays the consumer.
Losses in networks
Thermal energy losses in networks and for own needs of CHP (boiler) in the Ulyanovsk region in 2016 reached 9.5% of the total released energy consumers in the region, according to the materials dedicated to the development of electric power region for the years 2018-2022. The main consumer of heat energy in a population, it accounts for 55.5 percent of the total quantity of released heat.
This loss rate is not the highest. «If the network is in a normal state, the loss falling to 3-4%. Loss of 7-9% is considered average. There are losses of 20% or even 30% in a completely destroyed the system» — said the expert of the Analytical center under the Government of the Russian Federation Evgeny Gasho.
The cause of the loss is the wear of heat networks. In the Ulyanovsk region, for example, it is 62%. «The amount of heat loss through the insulation on separate sites reaches of 1.73 to 4.77%. Thus in the calculation of normative losses was used by the old rules, 1959, which is almost two times greater than current requirements. This means that the amount of losses on certain sections of trunk pipelines when calculating it in accordance with modern standards will increase almost ten times», — stated in the materials.
Due to wear of heat networks, as shown by the calculations in the materials of the Ulyanovsk region, the value of probability of failure-free operation in individual cases does not exceed 0.5% against the standard value of 0.9%. «So if you do not take effective measures the long-term nature to restore life, in the next five years, the number of cases of failures in thermal networks will be doubled and deal with the timely repair of damages will be almost impossible», — stated in the materials.
Have big losses and another unpleasant side. «When we created the system of tariff regulation, it was assumed that payment of losses up to 7% is included in the tariff, over — have to pay the utility organization. As a rule, most everything is in the rate», — says Evgeny Gasho.
If you figure out the amount of out impressive. For example, the total heat losses for the year 2016 in the same Ulyanovsk region amounted to 1,269 million Gcal. When the rate of heat not less than 1000 rubles per Gcal, while the rough calculations, it turns out more than a billion rubles.
Tests of heating systems tend to find not dozens, but hundreds of damage, elimination of which takes more than one day. Due to too much work time a repair campaign sometimes you have to extend.
«Now is the acceptable time limits domestic hot water in connection with the planned repairs to two weeks. But often, even in the official schedules of repair of the prescribed three-week period of the lack of hot water. As a rule, the deadlines for shutdown of hot water are broken, and many residents put up with it. But to allow the utility to exceed with impunity the timing of repair of networks, it is possible to sit without hot water and a month or two, and sometimes all summer,» — said the expert.
In case of violation of terms of repairs, suppliers may be imposed administrative fines. Today, such abuse includes a small amount of 1 thousand rubles for officials and 10 thousand rubles for legal entities. currently, the question of toughening of responsibility for violation of norms of providing the population with communal services. For violators of the proposed tougher penalties.
