Abstract
Heating and hot water has accounted for 68% of Korea's household energy usage. Boiler makes up the bulk of the heating and hot water production. Hence a highly efficient boiler is needed in order to reduce energy consumption. A condensing boiler that recovers latent heat is known to be highly efficient. However, it is expensive and takes more space to necessitate research for improvement. In the present study, we investigated condensation heat transfer of a surface roughened by etching treatment. The etched plate showed 9.2% increase in heat transfer compared to original plate.
