A while back I found a gas water heater timer on the internet. A friend of mine bought one. He is saving around 22% on his propane bill each month. That's big! Go to www.gaswaterheatertimer.com to see what it is.
I highly recommend the GAS WATER HEATER TIMER. It has proven testing showing energy savings up to 36%. See it at www.gaswaterheatertimer.com Open the PDF on the website and check out the test results.
This timer saves money on your gas bills, extends the life of your water heater, and can be used with any Home Automation or timer of your choice.
