1
The cost of one cubic meter of hot water is the ratio of the monthly cost of hot water per person to the monthly consumption volume of cold waterconsumed for the supply of hot water. To determine the cost of one cubic meter of water, make the following calculations.
2
To determine the monthly cost of hot water for one person, determine the cost of heat energy used for heating water. To do this, multiply the ratio of heat consumed for hot water supply per person (check with local authority) on the rate of thermal energy (see the Committee on tariffs of your city).
3
To determine the monthly value of consumption of cold waterneeded for hot water, multiply the monthly consumption of cold water (it can be in Committee on municipal economy) the price of cold water, approved by the head of your city.
4
Add the resulting value to the monthly value of consumption of cold waternecessary for the supply of hot water with the resulting value of thermal energy used for heating water. As a result, you will receive a monthly cost of hot water for one person.
5
Now you have all values needed to calculate the cost of one cubic meter of hot water. Divide the resulting value monthly cost of hot water for one person for the total monthly consumption of cold water for hot water.
