Electric water heaters are safe because they are flameless and flueless. Insulation Insulation reduces heat transfer and makes a home easier to heat or cool. Install insulation in your attic. We recommend R-38 in the attic. Insulation is inexpensive and has a quick payback.
Insulation is available in batts, blankets, loose fill, foamed in place and rigid board.
Adding insulation to existing walls and floors is sometimes difficult and costly. We recommend as close to R-l9 as possible in those areas. Other areas that need insulating include ductwork and exposed hot water pipes. Air Infiltration Air infiltration is the uncontrolled movement of air into or out of your home. It is caused by such factors as wind velocity and pressure differences due to operating the heating and cooling system.
