## Questions & Answers

**Q: How many gallons per minute?**
A: Hello-The GPM changes with the temp rise needed.... so its a sliding scale.Here is a performance chart you can review - http://www.rheem.com/product/tankless-electric-water-heaters-professional-classic-series-rtex-08-rtex-11-rtex-13 Go to - Specs/Docs tabI hope this helps :)ThanksBen

**Q: Can this water heater be used with a water softener that uses salt? Or will it damage it?**
A: You can use a water softener with the tankless water heater

**Q: Use inline with hot water line instead of cold? Wanting to use for outdoor shower and point of use for bathtub**
A: I am using this as a secondary hot water heater for my solar system.  Seems like a similar use as I supply it with up to 130 degree water.  It will adjust to heat the water to it's set point and heat no further.  if the water is already hot id does not turn on.

**Q: If i uninstall my hot water heater then instal the tankless will this still allow hot water throughout the house water supp???**
A: In theory, yes. The Rheem 11kW 240v Tankless Electric may not have enough power to supply a house with hot water. The 11kW is used at end destinations or can heat enough water for one bathroom or kitchen. If you have multiple bathrooms, look into putting one in each area; that way, you only heat water in the area you need. I recommend calling our tech support line at 800.374.8806 so that they can properly size the tankless water heater to fit your needs before you invest your time and money in purchasing the wrong unit.
