How can the Energy be Reduced, from Hot Water Pipes?

-Covering the Pipes with the Insulation reducing Conduction and Convection -Painting them White, reduces Radiation -Making them as Short as Possible so that the Water doesn't spend a lot of Time in the Pipes -Making them as Wide as Possible, meaning it has a Smaller Surface Area to Volume Ratio. [Less Volume of Water is next to the Pipe --> Less Conduction]
