    In the first phase of this study, the equipment that is part of the process for the heating of sanitary water in the machine room of the Hospital General Ambato IESS was identified. These components were classified according to their function, whether for the generation and distribution of steam and the exchanger, which is responsible for taking advantage of this fluid in order to add heat to the water that is then distributed to all the blocks of the institution. For the heating of the hospital's sanitary water, 35.526,152 gallons of Diesel No. 2 are required per year for steam generation. Calculations were made of the system losses during the most current period (April 2022 - July 2023) in order to identify any anomalies affecting the operation of the system, by analyzing numerical and quantifiable data. This resulted in an exchanger effectiveness of 41.46 percent. Thermal generation alternatives for sanitary hot water were proposed with the purpose of reducing the consumption of fossil fuels, establishing four possible systems to cover the energy demand, which are: solar thermal collectors and heat pumps; solar thermal collectors and steam; heat pumps and finally the recovery of sensible heat from the dry gases of the boiler chimney, determining that the most viable option are heat pumps because they cover the calorific consumption required per year, additionally its return on investment is shorter compared to the other processes, because approximately in a year and a half the financing will be recovered.
