  • Hot water every time…
Color: White Style: 4 Gallon Water Heater with Water Diverter
This heater came with everything needed for my 5th wheel, no issues or worries of breakers tripping and no more cold showers, hopefully since not in use 24/7, that it will continue to work for a long time, I recommend it

  • Great for saving space i.e. in a travel trailer, RV or tiny house
Color: White Style: 4 Gallon Water Heater with Water Diverter
Gave as a gift to my niece who now uses it in her travel trailer for washer, dishwasher, shower & sink. Her travel trailer is too small for a big water heater so this point of use water heater is perfect!

  • Short term solution
Leaking from the housing, will need to be replaced, for months in and it’s junk

  • Good water heater
Some of the fittings didn't match what I had, but hooked it up and it delivers hat water. Have it on a single sink in the barn so it's nice to wash hands with nice warm water

  • Water Heater
Color: White Style: 4 Gallon Water Heater with Water Diverter
Just what we needed for some hot water on our outdoor sink. Water heats up fast and is hot. Works well and quality seems very good. Easy to install. Good value for the money. Just installed it, so hopefully it will last a few years.
