Hot-water boiler, heating pipes and installation structure therefor

Abstract

The present invention relates to a hot-water boiler, which is particularly aimed to improve thermal conduction efficiency and thus to save energy by increasing the heating speed of hot water and facilitating the flow of hot water at the same time. The present invention is characterized by inducing and discharging air to the upper side of a raw water tank, and heating raw water and returning water while the raw water and the returning water fill at least 95% of the inside of a penetration section and an adaptor section, thereby significantly improving the internal expansion force.
