Pipe insulation energy savings.
A few years ago i had a home energy audit done as well and pipe insulation was one of the recommendations.
Energy cost savings after the first year are assumed to increase at the energy cost escalation rate.
Epa estimates that homeowners can save an average of 15 on heating and cooling costs or an average of 11 on total energy costs by air sealing their homes and adding insulation in attics floors over crawl spaces and accessible basement rim joists.
Enter average operating process temperature for the period of operation.
Starting at the water heater measure lengths of insulation needed to cover all accessible hot water pipes especially the first 3 feet of pipe from the water heater.
Pipe insulation seems to be a hot topic.
Energy savings from pipe insulation are very significant even in mild climates such as rockhampton.
Insulation materials run the gamut from bulky fiber materials such as fiberglass rock and slag wool cellulose and natural fibers to rigid foam boards to sleek foils.
Bulky materials resist conductive and to a lesser degree convective heat flow in a building cavity.
