Questions & Answers

Do you have to have soft H2O to use a tankless H2O heater?

by Joe D. on 03-01-2014

No, water must be portable (drinkable) for use with a Rheem RTE 7 tankless water heater.

I am looking for a water heater to serve one sink in my residential pole barn. Just need enough to wash my hands occasionally. Incoming well water is 40-50 degrees F. Would the RTE7 work for this application, or would you recommend a different unit?

by Jerry E. from Indiana on 01-06-2014

With a Max Flow Rate 2.5 GPM , this unit would fit your needs as it will raise the temp. about 20 - 80 degrees depending on the amount of flow you are washing with .

Are any of these hot water heaters 110 voltage.

by ANN D. on 07-07-2012

Yes, The Rheem RTE3 (click here to view) is a 110V Tankless Electric Water Heater. It is a smaller model than the model listed above. The Rheen RTE3 is suitable for a single sink, and will require more than one unit if used for multiple sinks. 

The larger units require more electricity, requiring a 220V connection to operate properly and efficiently.
