Which is the best method to insulate a water heater?

An insulation blanket can make some water heaters more energy efficient. If your water heater is located in unconditioned space (a garage, basement, or attic) or you don’t want added heat, install a heavy blanket — R-11 or better. The higher the R value, the thicker the blanket and the more insulating horsepower.

Do water heater blankets work?

Should you insulate your hot water heater pipes?

Insulating your hot water pipes reduces heat loss and can raise water temperature 2°F–4°F hotter than uninsulated pipes can deliver, allowing you to lower your water temperature setting. You also won’t have to wait as long for hot water when you turn on a faucet or showerhead, which helps conserve water.

Do new water heaters need insulation blankets?

Newer water heaters—those ten years old or newer— tend to be well insulated. If someone has an older electric water heater that’s still working then a blanket is probably a good idea. Water heaters are always under pressure and tend not to give any warning before they leak copiously.

Does turning down water heater save money?

Homeowners will find that by turning down their hot water tank temperature by about 20 degrees to 120 Fahrenheit or 48 Celsius, they will see cost savings of about 6 to 10 percent.

Why are copper pipes not insulated?

Copper’s high conductivity means it is great for transporting hot water in central heating systems, but just as the pipes get very warm, they can also get too cold. Insulation prevents this by raising the surface temperature of the pipe and forming a water-vapour barrier.
