This will save you around 4%–9% in water heating costs. 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.\"\n\nhttp://web.archive.org/web/20120906013629/http://www.energysavers.gov:80/your_home/water_heating/index.cfm/mytopic=13070\n\n== See also ==\n\n[http://Sunecochina https://www.sunecochina.com/what-happened-to-energysavers-gov/]\n\n{{Page data\n| license = CC-BY-SA-3.0\n| keywords = Thermal insulation, Energy efficiency, Construction\n| sdg = SDG07 Affordable and clean energy\n}}\n\n[[Category:Energy efficiency]]\n[[Category:Construction]]"}
