This work analyzed the loss of sensible heat from one fluid to be considered homogeneous heat distribution on a thermal reservoir with cylindrical geometries composite insulating layers. We studied two thermal reservoirs with a volume of 20 liters, and the first has a layer thickness of 75 mm of expanding polyurethane foam wrapped in the polycarbonate container and the second container has only layer thickness of 5 mm of polycarbonate, as insulation of fluid of the external environment. The experimental results are compared with theoretical results obtained through a calculation script, displayed and detailed during the work development, from the theory of energy balance. The maximum error introduced between the theoretical and experimental results were 3.5% and 1.4% respectively for the Boilers with or without a polyurethane coating
