PURPOSE: An inverted boiler using a coil multi-layered heat exchanger is provided to enable perfect combustion and improve economical efficiency by preventing dew condensation. CONSTITUTION: An inverted boiler using a coil multi-layered heat exchanger comprises a heat exchanger(10), a water supply tank(20), and a hot-water storage tank(30). The heat exchanger is spirally positioned by attaching coil heat exchanging tubes(5) closely to each other. The water supply tank is connected from the both sides of the heat exchanger to the inlet of the heat exchanging tube. The hot-water storage tank is connected to an outlet(4) of the heat exchanger and circularly supplies hot-water. A guide part(15) is installed inside a barrel body(2) of the heat exchanger. |
