In the article it is considered the problem of creating a combined heat system of houses and public facilities in rural areas, alternative heating system using natural gas. During analysis of the possible options have been substantiated sources of energy for the combined heating system: such as electrical systems, gas, solid fuel boilers individual, alternative energy sources - wind and solar. It was found that the power of the wind flow is directly proportional to the area through which it passes, and the cube of the wind speed. For many regions of Ukraine has great potential for the use of wind energy, especially for the southern and mountainous regions, which can significantly (up to 20%) to cover the energy needs for heating. It is proposed the method of electricity use for heating at night, when the failures of the load in the energy system up to 40-50%, and the outdoor air temperature during this period is the lowest. It is shown that the ambient temperature during the day varies sinusoidally that should be considered when determining the required capacity of the coolant. It is proposed a method for determining the required capacity of coolant within the time of day (once per hour) as a function of ambient temperature and a predetermined temperature in heated area. It is offered a minimum value of the total amount of energy obtained from different sources as a condition of optimal operation of the combined heat systems of houses and public facilities.
