Water heaters or "hot" water heaters, as some call them, are not what they used to be.  Now you can be "green" with a tankless water heater that provides instant hot water to your system.  With the advent of the tankless water heater, people are finding ways to go green and save a significant amount of money on their utility bills. See comments about how instant hot water lowered gas bills (below the video).


"You installed the tankless water heater in my house in February.  Here are how my gas bills compare for the same months in 2009 vs. 2010 with this system in place."
