  • Works great
Style: ExploreFlow Max
Great upgrade for our RV! This Ranein tankless water heater has made a huge difference in our RV. It heats water fast and keeps the temperature steady—no more cold or stop and go showers! Max Temp is 120 F. The external shower is super handy, and the controller is simple to use. Works great for our camping trips. So nice to have a nonstop long shower when on full hookup. Totally worth it! ... show more

  • Door Not Included - Super Hot Water at Altitude
Style: ExploreFlow Max
Heater works great - the listing says it comes "standard with a 15 x 15 door", it does not and the manufacturer refuses to honor their listing. Yeah... could return it, but it actually works well. The door is another $80, so a full unit is actually over $600.

  • Worth the money
Style: ExploreFlow Max
