<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Corbel","sans-serif"'>Heating
water accounts for up to 30 percent of the average home's energy budget. Some
makers of gas-fired tankless water heaters claim their products can cut your
energy costs up to half over regular storage heaters. So is it time to switch?<br>
<br>
Probably not. Gas tankless water heaters, which use high-powered burners to
quickly heat water as it runs through a heat exchanger, were 22 percent more
energy efficient on average than the gas-fired storage-tank models in our
tests. That translates into a savings of around $70 to $80 per year, based on
2008 national energy costs. But because they cost much more than storage water
heaters, it can take up to 22 years to break even—longer than the 20-year
life of many models. Moreover, our online poll of 1,200 readers revealed wide
variations in installation costs, energy savings, and satisfaction.<br>
<br>
With the help of an outside lab, we pitted Takagi and Noritz gas-fired tankless
water heaters against three storage water heaters. We didn't test electric
tankless heaters because many can't deliver hot water fast enough to replace a
conventional water heater if groundwater is cold. Even in areas with warm
groundwater, most homeowners would need to upgrade their electrical service to
power a whole-house tankless model.<br>
<br>
Our tests simulated daily use of 76 to 78 gallons of hot water. That's the
equivalent of taking three showers, washing one laundry load, running the
dishwasher once (six cycles), and turning on the faucet nine times, for a total
of 19 draws. While that's considered heavy use compared with the standard
Department of Energy test, we think it more accurately represents an average
family's habits. We also ran more than 45,000 gallons of very hard water
through a tanked model and a Rinnai tankless model to simulate about 11 years
of regular use.<o:p></o:p></span></p>

Sustainers,<br>
Has anyone used a tankless water heater system in their
homes? Do they last? Do they really save on the power bill?
The government is now offering a tax credit for new purchases and I am
interested IF they really do save energy as promised.<br>
Thanks for sharing your experience.<br>
