:142 Water Heater Insulation

Welcome to today’s 1:5:10:365 Tip for becoming a better steward for our home and planet.

1:5:10:142 EcoTip: According to the US Department of Energy: “Unless your water heater’s storage tank already has a high R-value of insulation (at least R-24), adding insulation to it can reduce standby heat losses by 25%–45%. This will save you around 4%–9% in water heating costs.”

***********************************

 Additional Information:

If you don’t know your water heater tank’s R-value, touch it. A tank that’s warm to the touch needs additional insulation.

Insulating your storage water heater tank is fairly simple and inexpensive, and it will pay for itself in about a year. You can find pre-cut jackets or blankets available from around $10–$20. Choose one with an insulating value of at least R-8. Some utilities sell them at low prices, offer rebates, and even install them at a low or no cost.
