1. Girard tankless water heater (Top-Pick)

Girard Tankless Water HeaterGirard tankless water heater is the result of years of research and contains all the features that an RV tankless water heater must-have. You will get unlimited hot water whenever you want. You can mix the hot and cold water to adjust the temperature.

You can adjust the temperate from 95F to 124F and can change the temperature to Celsius. It has a feature that once the temperature of the water is adjusted it will not fluctuate.

This is really good for parents because water does not get very hot or very cold. Troubleshooting of this unit is easy because of the visual diagnostic and you can easily operate this unit.

According to a buyer

I live approximately 300 days a year in an RV. The worst part about RV living is the 3-minute shower associated with the 2.5 GPM water heater. This thing is an absolute lifesaver! It produces hot water in about 5 Seconds and runs indefinitely. Well, at least I’ve personally run mine for about 35 to 40 minutes and it gave continuous water at my preset desired temperature. The instructions specifically state “Professional installation only” however if you have basic knowledge of plumbing and 12 volts DC Power Systems you have all the knowledge necessary to install this unit. Keep in mind that if you do install this unit yourself, you are most likely voiding your warranty from Girard. So far I’m very impressed and would definitely put this in any future RVs.

Things we like?
  • Endless hot water
  • Safe to use
  • Quiet brush-less motor
  • Easy installation
  • Easy troubleshooting
  • Temperature control
Things we don’t like?
  • A bit expensive

I love this unit. We live full time in our rig. When I started considering a tankless water heater, I heard a lot of pros and cons. This unit has erased any doubt that tankless is the way to go. My rig has a full-sized bathtub and my wife loves that she can fill the tub completely with hot water. Although this unit is on the pricey side, it’s well worth the money.

They were very helpful and impressive. Thanks, Gary at Precision Temp.”

Loving it so far. Heats the water up very quickly, well made, super-fast to hook up, even with high water pressure it heated the water to as hot as you want it very fast. Great product. Highly recommend and have a drain screw for draining the remaining water in the unit if freezing weather outside. A lot of the other competitor companies don’t have a drain screw on them so the water can freeze in the heater coils and wreck them. This one is perfect.”
