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.

Executive Summary
The NuvoH
2
O Efficacy and Consumer Benefits Study tested tankless water heaters supplied with
NuvoH
2
O softened water and untreated hard water under controlled laboratory conditions designed
to accelerate the waterside scaling and then quantify the scale growth and the performance
efficiencies.
The independent study specifically focused on the effectiveness of the NuvoH
2
O systems in (1)
preventing scale and protecting the appliance from the corrosive and destructive power of scale, (2)
preventing scale and producing an energy savings for the consumer, and (3) removing scale and
returning appliances to a more efficient state of operation.
The study protocol was developed by Battelle, the world’s largest nonprofit research and
development organization. For this study, Battelle tested 15 Bosche RP17PT electric tankless water
heaters and using treated municipal water with approximately 15 grains per gallon hardness
(anything above 10.5 per gallon is considered to be very hard water) and a pH value of about 7.8 –
8.0.
The first phase simulated approximately 2.2 years of water heater use in approximately 4.5 months
of testing. Five (5) NuvoH
2
O-treated instantaneous electric water heaters (IEWHs) and ten (10)
untreated IEWHs were set up for continuous testing. Battelle performed teardown analysis on five
(5) NuvoH
2
O-treated heaters and five (5) selected untreated heaters at the end of the first phase to
assess scaling in the water heaters.
The treated and untreated water also flowed through corresponding Delta RP42578 showerheads
that provide full spray at the identified test flow rates/pressure to further analyze scale growth.
For the second phase of testing, the remaining five (5) untreated water heaters were transitioned to
installation with NuvoH
2
O Systems. The intention of Phase II was to document NuvoH
2
O
System’s ability to remove existing scale and improve appliance efficiency. The heaters selected for
the second phase of study exhibited various degrees of scaling which served as the baseline heater
condition.
