Water heaters:
A large percentage of the cost of running a water heater is due to the "stand by" losses, the cost of keeping the water at the selected temperature. Consider setting the water heater to the "Vacation" setting or the lowest temperature setting. Make sure you record what temperature it should be set back to when you return (a normal operating temperature of 120°F is safe & energy efficient). Turning it off may not be the best idea; the life of some water heaters can be shortened, you can risk freezing pipes in winter, & you can have a considerable wait for hot water once you turn it back on. Setting your water heater down but not off, can save you up to $10/month for electric water heaters or $4/month for gas.
Set your gas heater valve on the vaction and you will be Ok see the Iamge, Thanks.
