We were initially contacted by Mr. O in Talladega Alabama because his tankless water heater wasn't working properly and was leaking. We found that the hard water in Talladega had built up inside the heater. Repairing the heater was an option but considering the age and repair cost, Mr. O opted to replace his tankless heater with a new Rinnai Tankless Water Heater. He also decided to protect his new tankless water heater from the hard water in Talladega by installing a SmartChoice HE water softener and a carbon filtration system. Now he enjoys endless hot water that is soft and chlorine free.
Tankless water heaters have a typical lifespan of 20 years...IF they have soft water flowing through them. If you don't don't have a water softener, an annual flush and tune up is required to keep the hard water from building up on the heat exchanger and other parts that touch the water.
