    New water heaters are well insulated, so they don't lose heat, but if you have an older hot water heater, it may not be as well insulated. Look up the R-value of your water tank in the owner's manual, and if it's less than R-24, install an insulation blanket.

    Heat can also escape your hot water heater through the cold water inlet pipe and hot water outlet pipe.

They're inexpensive valves (or loops) designed to prevent hot water from escaping up the pipes when your tank isn't in use. Energy.gov says adding heat traps saves $15-30 a year, so they'll pay for themselves in a matter of months.
