In addition, as the temperature of the heating water supplied to the latent heat exchanger (5) through the circulation pump (4) is lowered, it is heat exchanged with the combustion gas inside the latent heat exchanger (5), and the heating return is easily below the dew point temperature, so that condensation occurs. When the temperature of the combustion gas is lowered due to this, the heat quantity of the combustion gas discharged from the condensing gas boiler is lowered, so that the heat transfer efficiency is increased. As a result, the temperature of the exhaust gas discharged through the latent heat exchanger 5 is also high, which causes excessive heat consumption.

However, when the stainless material is used, the heat transfer efficiency is lowered, so that the volume of the latent heat exchanger 5 has to be large in order to secure the same amount of heat.
