Ut oh. I found a controller that will attach to the gas control valve on my gas water heater that will let me turn the knob from the heat setting the the vacation setting with a timer or home automation controller.

Have mine set on 130°F and also has a VAC setting that keeps it above 55°F to keep it from freezing.

Basically only really use hot water for Showers, dishwasher, and clothes washer. The clothes washer I found works best on warm/warm so it doesn't tax the water heater that much. My dishwasher has a temp booster. Thinking heating the 40 gallon water heater up to temp just once a day so it's hot for showers and I'd never notice and save a bunch of monies!

Wonder just how long it takes to heat the water, and how long it takes the water to cool enough that you'd notice after it is set to vacation mode. My tank is insulated pretty well, it is cool to the touch.
