The pipes that provide hot water to showers, faucets, and other appliances in your home may leak energy. You could lose lots of heat based on the distance that the water must travel and how far it has to travel.
Adding insulation to hot water pipes can increase the water temperature by 2 to 4 degrees. Insulated pipes not only increase the amount of hot water available, but they also eliminate the need to run the water continuously while you wait for hot water to be ready for showers.
