Tankless Water Heater
Scale can build up on heating elements, making your tankless water heater work harder. Independent testing conducted with Battelle Memorial Institute found that NuvoH2O prevented more than 98% of scale buildup and helped electric tankless heaters reach full temperature more than 25% faster.
Dishwasher
The Dishwasher System helps prevent scale inside your machine and reduces the spots and film left on dishes and glassware. Prefer a solution with no installation? Dishwasher Scale Preventer Pucks go directly in the machine and last up to three months.
