  4. Water is intantly heated up as it circulates through the heat exchanger and out the tap


  • Never run out of hot water again!
  • Designed specifically for RVs
  • Takes up half the space and weighs one third as much as a ten-gallon tank
  • No pilot light and very high efficiency
  • Straightforward installation
