Pipe Insulation Energy Savings

25 4 mm of fiberglass insulation we can estimate the value of the annual energy savings.

Pipe insulation energy savings.

Using figure 2 for values of energy use for bare pipe and pipe insulated with 1 in. For a complete energy audit and an estimate of your fuel savings speak to one of our insulation experts today 855 867 8200. 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.

Energy savings from pipe insulation are very significant even in mild climates such as rockhampton. Enter average wind speed for the period of operation if unknown use 1 mph for indoor 8 mph for outdoor line 6. Enter the projected annual energy cost escalation rate yr 3 0. 5 energy saving ways to avoid needing an electric space heater.

2 cut the pipe sleeve. Predicted annual energy savings 4 05 lf 17 43 lf 2 35 lf 61 per year. Energy cost savings after the first year are assumed to increase at the energy cost escalation rate. 1 1 2 insulated pipe saves 3 170 160 btus per foot per season estimated savings 18 65 per foot per season.

Across all climates zones savings ranged from 0 16 to 3 5gj per system. Rigid foam boards trap air or another gas to resist conductive heat flow. See the march 2013 issue of insulation outlook for instructionson on using the energy calculator for horizontal piping. 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.

It s also a good idea to insulate the cold water inlet pipes for the first 3 feet. Select nominal pipe size nps. Enter average operating process temperature for the period of operation. Enter average ambient 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. A few years ago i had a home energy audit done as well and pipe insulation was one of the recommendations. Estimate the annual savings. Cut the insulation to the lengths needed.

Theoretical energy savings by insulating your facility. Methodology for estimated energy savings from cost effective air sealing and insulating. 3 place the pipe sleeve.
