Study Findings and Executive Summaries NuvoH2O Efficacy and Consumer Benefits Study: Scale Prevention Scale Removal Energy Savings An Independent Study by Battelle
Efficacy and Consumer Benefits Study www.nuvowater.com Table of Contents Introduction Study Findings Executive Summary Conclusion The Independent Consumer Benefits Study of nuvoH2O was conducted from 20112012 in conjunction with, but not endorsed by, the Battelle Memorial Institute and funded by nuvoH2O.
Efficacy and Consumer Benefits Study Introduction The NuvoH2O patented design and proprietary formulation was developed from almost thirty years of commercial experience. First designed for the food services industries, these products have helped solve complex water problems for some of the nation’s largest businesses.
Efficacy and Consumer Benefits Study An estimated 85% of the United States face hard water issues. Primary concerns of hard water for consumers are the decreased life of any appliance, fixtures and plumbing subjected to scale build-up and increased energy consumption to heat water for household use. First, hard water build-up clogs and corrodes pipes, fixtures and appliances shortening their lifespan by as much as 25-30%.
Efficacy and Consumer Benefits Study Figure 2. Battelle Lab Study Findings Scale Prevention. The results of the Battelle study are conclusive - the NuvoH2O System prevents the formation of scale. The visual assessment of the heating elements after teardown analysis clearly shows that the NuvoH2O systems prevented scale. The visual observation is supported by the detailed breakdown quantifying the exact scale amounts.
Efficacy and Consumer Benefits Study Executive Summary The NuvoH2O Efficacy and Consumer Benefits Study tested tankless water heaters supplied with NuvoH2O 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.
Efficacy and Consumer Benefits Study Phase I Results The objective of the first phase was to assess NuvoH2O water softeners’ ability to prevent scale, and to determine the longevity of the appliances and fixtures and resulting energy savings from use of the NuvoH2O Systems.
Efficacy and Consumer Benefits Study Figure 4. Untreated Canister (Left) and Treated Canister (Right) Analytical Assessment. To quantify the visual assessment of the scale in the test heaters, the scale from the heating elements and canister for each respective heater was dissolved using 5% w/w Sulfamic acid (H3NSO3) solution. Calcium and magnesium concentrations for each sample were determined via atomic absorption spectroscopy (AA) and used to report mass of the scale deposited as CaCO3.
Efficacy and Consumer Benefits Study 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/oF).
Efficacy and Consumer Benefits Study Phase II Results The objective of Phase II was to determine the ability of the NuvoH2O Systems to restore performance, efficiency, and aesthetics to scaled water heaters and showerheads. Untreated water heaters from the first phase were installed downstream of NuvoH2O Systems to determine the efficacy of the NuvoH2O systems to remove scale.
Efficacy and Consumer Benefits Study Figure 7. Phase II heaters displayed a decrease in time to steady state. The study found that the NuvoH2O system can remove scale and restore efficiency. Of the water heaters tested in Phase II, the majority displayed significant improvement, one showed little to no improvement and one actually failed.
Efficacy and Consumer Benefits Study Conclusion The use of the NuvoH2O System will (1) prevent scale and protect the appliance from the corrosive and destructive power of scale; (2) prevent scale and produce energy and potentially a water savings for the consumer, and (3) remove existing scale and in most cases return appliances to a more efficient state of operation.
