Why heat metering promotion is good or bad?

"Fewer and no more" users have low energy saving enthusiasm

Heating metering charges have always been a good vision for heating bills. On the one hand, residents have taken the initiative to use hot consumption, and each family can use how much money it zealously needs according to actual needs; on the other hand, it greatly reduces social resources. The waste of heat energy is conducive to green and low carbon and energy conservation. However, at present, the users of metered-heating trials in the Harbin Municipality do not need to make additional payments in excess of the heat fee paid for the use of the area. If the heat is less than the heat fee paid, the reimbursement of the heat fee will be refunded. This reduces the energy-saving enthusiasm of many users.

During the heating period from 2010 to 2011, the temperature set at Mr. Wang's home in Building No. 4 of the second phase of the oasis community in Hakka City was 23°C. Users like Mr. Wang account for the vast majority of pilot communities.

The reporter learned from the large urban oasis community in Harbin that, since the user installed the heating metering device, more than 90% of the user's room temperature was set above 20°C. Among them, users above 22°C accounted for 80%, and 28% were users. Above 24°C (The maximum temperature allowed for remote control is 25°C). “At present, the price of heating in Ha’er is measured at room temperature and 18°C. However, in the measurement heating experiment, even if the user exceeds this temperature, there is no need to pay for the heat charge. Sun Fulian, manager of Harbin Chaoran Property Company, said, precisely because The government’s current hot money policy has a small correlation with the user’s economic interests, resulting in the user’s inability to save energy, and energy saving and environmental protection has become wasteful and environmentally unfriendly.Fang Xiubing, a professor at Harbin Institute of Technology, believes that the current measurement of district heating in Harbin It is a success and there are no technical problems. The key to achieving energy conservation lies in the government's correct guidance.

To promote metered heating needs multiple

In the measurement and heating pilot community in Harbin, the user’s home at 20°C still requires a part of the heat fee, which makes the company responsible for the pilot feel very aggrieved. “Because the metered heating pilots do not make up for more use and less use the refunding fee policy, users who have even reached room temperature of 20°C will also be refunded. According to statistics from 2010-2011, 20% of users with indoor temperature of 20°C will have to retreat. Part of the hot money. Who will give me the extra expenses?” Sun Fulian said aggrieved. According to experts, the reason for this situation is that the user set the temperature is low, but due to the heat transfer effect, the surrounding user's room temperature is high, the user's room can increase the temperature by 2-3 °C, which leads the user to enjoy the temperature, but only Pay a lower heat charge than this temperature. The surrounding users indoor 25 °C, but do not have to pay more. This has led to the phenomenon that users still have to pay a fever fee at 20°C in their homes. In order to solve this problem, when piloting, either the government will change its policy, users will pay the heat fee according to the actual amount of heat, or the government will subsidize heating companies to pay more for this.

Prof. Fang Xiujin proposed that heat is a special commodity, different from water and electricity, and conductive, so the measurement is suitable for the overall consumption of each building, indoor meter can be used as distribution data, as long as the indoor temperature of the same area of ​​the household or The same amount of heat, it should pay the same heat fee. Jilin Province has started to charge per floor heat consumption this year. In addition, for newly-built houses, heating management personnel suggest that the integrity of the heating system must be guaranteed when the building is completed for sale. If the metered heating is to be widely promoted, the government must strengthen the requirements for the new metered heating installations for the newly built houses. From the design of the house heating to the acceptance handover, each link can meet the requirements for metered heating before it can be sold.

Less investment and less companies are reluctant to participate

For metered heating, many heating companies in Harbin say they are reluctant to participate.

Mr. Zhang, a person in charge of a large heating company, told reporters that if he participates in the measurement and heating promotion under the existing policies, the company will suffer three losses. First, input costs. Current metered heating requires companies to bear the bulk of their own, which is totally invested; second, it reduces heat fee income; and third, it increases the cost of managing and testing and maintaining metering devices. In this regard, Sun Fulian, manager of Harbin Chaoran Property Company, which has been conducting pilot heating measurement for two years, said: “In order to conduct measurement and heating reconstruction, we have invested more than RMB 16 million and have just completed acceptance last year. However, in these two years of trials, The company is losing money every year. It's a bit unbearable," Sun Fulian said. The heating price in Harbin City is measured and measured at room temperature of 18°C. However, if the pilot companies want to realize the user's need to use heat, they must adjust the set temperature themselves. Allow the user's room temperature to reach the maximum setting of 25°C. Therefore, the company's heating temperature also increased accordingly. However, as users use more heat and do not pay more to pay for the heat, they will lose energy-saving power. The increase in costs for companies to increase the heating temperature becomes an additional burden, and there is no way to recover the input. During the interview, the ministry heating enterprises were not satisfied with the existing metering and heating policies. They believed that since energy saving and environmental protection benefited the whole society, it would not be possible for the heating company to bear the costs and increased costs.

For the current status of metered heating in Harbin, the industry expressed concern. In the past two years, the newly-built houses in Harbin City have been equipped with metered heating equipment as required by the state. If the enthusiasm of heating companies cannot be mobilized, the enterprises will be profitable, and it will be difficult to fully implement metered heating, and a large amount of metered heating facilities will be wasted. .
