Efficacy and Consumer Benefits Study
The Independent Consumer Benefits Study of nuvoH2O was conducted from 2011-
2012 in conjunction with, but not endorsed by, the Battelle Memorial Institute and
funded by nuvoH2O.

Water Heater Efficiency: Steady-state Temperature. A key metric used to track water heater
performance is time to steady state operational temperature. The time to steady state operational
temperature is the amount of time it takes for the heater to consistently deliver the user-set
temperature once the heater is active.
This metric is expressed in seconds per degree Fahrenheit (sec/
o
F). This represents the time taken
by the water heater to heat the water by one degree and is directly proportional to the cost of energy.
The NuvoH

O-treated systems responded in an average of 8.34 (sec/
o
F) versus 10.6 (sec/
o
F) for
non-treated heaters – over 27% less time on average to reach the steady state performance.
The scale on the untreated heating elements acted as a barrier to the heat transfer, whereas the
Nuvo-treated elements were able to directly transfer the heat from the copper elements to the water.
As water heating is the second largest energy expense in a typical household according to the U.S.
Department of Energy (DOE), it can be directly translated that a scaled heating element can cause a
higher energy bill than an un-scaled element. For example, when a user is waiting for the tap water
to heat to the desired temperature, the user will let the water run longer which in turn increases
water as well as electricity consumption (See Figure 6).
