In Seffner, where standard water accelerates scale formation, this maintenance is essential for performance and longevity. Florida water generally has moderate mineral content that builds up over time. The descaling process takes about an hour and uses a vinegar solution pumped through the unit. We also check the inlet filter, ignition system, and venting during service. Skipping maintenance can void the warranty.

A: Tankless units are sized by flow rate (gallons per minute). A unit providing 8 to 10 GPM handles most Seffner households of 2 to 4 people. Larger homes or households that run multiple hot water fixtures simultaneously may need a higher capacity unit or multiple units. In Seffner, where incoming water temperature is around 72 degrees, tankless units perform efficiently because the temperature rise needed is lower than in colder climates.
