Abstract


In this study, a comparison and economic analysis of energy required for heating and hot water by condensing and conventional combi for a family was performed. After determining the energy for the family the cost of consumption energy calculated which was supplied by each two types of combi. It was determined that using of condensing combi will provide the average 15,6% energy savings to family. Furthermore, the average 40% impairment of the exhaust gas temperature of condensing combi than conventional combi causes the reduction of emissions rate and decrease the global warming. Reduction of emissions is extremely important in terms of air pollution. Compared to a conventional combi the initial investment of a condensing combi is high, but due to usage of latent heat of water vapor in the exhaust gas the payback period is short, and therefore the cost difference could be ignored. This study emphasizes that, usage of the condensing combies which are compulsory in European Union countries, will contribute the family budgets and national economy.
