Also cost effectiveness of hot water generation using a boiling plant on natural gas was specified. A comparative analysis of technologies of hot water supply systems examined is given. It was defined in a calculated manner that full production costs of hot water generation (US dol./year) are equal for both technologies. A cost price of 1 gram calorie of heat for heating water using a heat pump is a little lower than using a boiling plant. But the payback time of a heat pump hot water supply system under Russian conditions is longer. It is shown that the system of hot water supply using a boiling plant provides a quick repayment and so is economically an effective trend.тепловой насосгорячее водоснабжениеэкономическая эффективность
