The article presents an analysis of energy consumption and the cost of its production by the systems of supply of hot water depending on the applied heat sources and destination of a building. The calculations have taken into account the efficiency of the adopted installation solutions that have a direct impact on energy consumption. The following parameters have been determined: the size of the seasonal demand for hot water, an annual amount of fuel needed to its production and annual operating costs. The calculations have been performed for residential buildings and public buildings, whilst maintaining the same usable space. The aim of the article is to determine the rate of the amount of fuel, needed to heat to the desired temperature, a unit volume of water depending on the type of heat source and destination of a premises. For the adopted variants of installation, the ratio of production costs of unit volume of hot water has been also determined. The indicators of the fuel amount and the cost of hot water pointed out in the article may be one of the criteria for selection of an effective system for the preparation of hot water.
