Depending on which model of tankless water heater you purchase,
and what size storage tank you have now, and if it runs on
gas or electricity, you could save anywhere from 5% to 69%
off your hot water heating bill. How? Most homes use hot water
for a cumulative total of about one hour per day, yet they
typically keep 40 or 50 gallons (oftentimes more) of water
hot 24 hours a day. Having a system that eliminates the storage
and heats water only as you use it can dramatically reduce
your energy consumption.
