Hello. I have 2 Noritz tankless natural gas water heaters, each with its own H2Flow filter. I know the manual says to change the H2Flow filter every 2 years, but I don't want to change the filters earlier than is really necessary. Is there some way to tell when the filter needs to be changed or are we stuck using the calendar as a guide?
According to Tucson Water company, the hardness is 247 mg/L in my water zone (and Sodium is 65 mg/L, Minerals 505 mg/L, pH 8.0). My household is 2 adults who love long showers, but we don't use hot water for clothes washing, and the dishwasher is only run 2x week.
Any advice appreciated!
This is my second home with tankless. The first home was with an electric unit (no gas in the neighborhood). The tankless replaced a tank for (a) unlimited hot water and (b) reclaim space. We had to de-scale it every 4 months or we'd stop getting hot water. Now this second home is zoned into two halves so that hot water lines/runs are relatively short - one zone has the master bath which is heavily used and a second bath (rarely used), and the other zone has the kitchen and a 3rd bath (rarely used). Our hope is that with the H2Flow filtering we won't have to do the de-scaling operations at all. Not that the descaling is a difficult chore, we just know for many reasons we're better off with as low a maintenance schedule as possible.
Thanks,
Amy
