The present invention relates to a boiler system with dual hot water tanks. More specifically, the invention provides a boiler system with dual hot water tanks wherein one boiler comprises high-temperature and low-temperature water tanks. The invention mixes high-temperature water in the high-temperature tank with low-temperature water in the low-temperature tank at different flow rates in a mixing valve, and supplies hot water at a preset temperature to a water supply heat exchanger so the temperature of the heated water in the water supply heat exchanger is constantly maintained. The present invention can supply hot water at a constant temperature always suitable for use and is free from inconvenience or discomfort caused by thermal deviation, because hot water at a temperature higher or lower than the preset temperature, is mixed with the preset-temperature water, and then supplied to the water supply heat exchanger. |
