Is it reasonable to charge more than 2200 yuan for the installation of collective solar property in residential areas? Hot water still costs 8 yuan. I installed my own water heater to find him.

It takes about 4 thousand to install a brand of solar water heater, and there will be costs for maintenance in the future, and the installation cost is reasonable. 8 yuan a cubic meter is the operation cost, including maintenance cost and spare parts cost, but it is mainly the electricity fee for electric heating in rainy days. If you install a100L household electric water heater, it is obviously reasonable to take a bath with 60L water, the temperature will rise by 30~70 degrees, the power consumption will be about 2~5 degrees (low in spring and autumn and high in winter), and the electricity fee will be 1.6~4.0 yuan. But the key question is whether the total capacity of the solar hot water system installed by the property for your building matches the number of users and the frequency of use of the building, and whether there is design redundancy (consider the amount of hot water other than bathing; Leakage loss of pumps, pipes and valves; Heat loss in rainy season), if only 80% people can use it, plus the loss of 10%, 30% people can't take a bath (it is unimaginable to run home to take a bath early every afternoon). Therefore, the property company should be required to show the relevant design parameters of the solar hot water system to ensure the use of hot water after paying the money. I once lived in a residential area in Kunming West Development Zone for 2 years. Its public solar hot water system has no hot water after 7 pm and little water in the afternoon. )
