If your home is served by a traditional water heating tank, you’re pouring energy into heating water 24 hours a day, whether you need hot water or not. What a waste!  If it’s almost time for you to replace your current hot water heater (before it does something dramatic like spring a leak), consider switching to a tankless hot water system. 

Tankless water heaters wait until you turn on the tap to begin heater hot water, and it may take up to 15 seconds before you reach the temperature you desire, but is that really much longer than your current system?

You can save 27 to 50% of your water heating costs by switching to a tankless heater.
