The presence of this energy in the country makes it suitable for heating or cooling residential and commercial spaces. In this paper, the thermal load of a home built according to energy efficiency standards is simulated. The air conditioning system based on the geothermal heat pump and the solar collector is modeled on the house using the Transmission software, and the effect of using the heating element of energy recovery from wastewater in the system, the technical-economic system performance in different cities of the country in terms of climate and efficiency. The solar collector component is examined for the average storage temperature. The results show that the heating used by the recycling component leads to the 0.9% increase in the temperature of the heat pump inlet in a five-year period and an increase of 1.9 degrees Celsius on the average temperature of the hot water tank during one year. The system’s performance in warm and dry climates is 25047 $ better than elsewhere in the country.
