Features

  • RV On Demand Water HeaterBoasting a powerful 48,000 BTU, the KINGRVER RV tankless water heater delivers a remarkable 2.5 GPM of hot water. Its optimal performance is enough to supply an entire RV with endless hot water. The tankless RV water heater effortlessly supports multiple hot showers and dishwashing without preheating, making it a versatile and efficient choice for RVers.
  • Efficient and Energy-Saving48,000 BTU can also provide adequate hot water as a higher BTU while saving propane. Staged combustion technology prevents overheating in summer and conserves propane. The tankless heater only activates when you turn on the water, unlike tank heaters that run constantly to keep the water at the set temperature. This makes the KINGRVER RV tankless water heater an economical and environmentally friendly choice.
  • Great ReplacementIt is easy to replace Suburban, Dometic, and other 6/10/12 gal tank RV water heaters. The KINGRVER RV tankless water heater opening size is 12.7" x 12.7". The fitting door kit is available for purchase in 3 sizes: 15" x 15", 15" x 18", or 18" x 18", which is ideal for different modifications when replacing other RV tank water heaters.
  • Wide ApplicationThe KINGRVER RV on-demand Water Heater can operate at above 5000ft high altitudes. What's more, this tankless hot water heater extends its usability beyond RVs, reaching remote, off-grid cabin homes on hills. A portable power station effortlessly meets its low DC 12Volts power requirement, ensuring a hot water supply in any environment.

    • Do not buy for an RV
Color: 48,000 BTU
Returned it twice, the first one didn't work at all. Returned, got the second one.. Installing it wasn't to hard, but, then things got interesting, to get it to even turn on you have to have far, far too much water pressure, literally have to turn on 2 or 3 hot water faucets in the RV on full to get it to turn on At All. If you only have 40 gals of water you do NOT want to have to drain your tank twice as fast to just get luke warm "hot" water. Returned the second one to Amazon and bought a different brand elsewhere. ... show more

    • So far absolutely PERFECT
Color: 48,000 BTU
I am a novice at all this and it was very easy to install. Works perfectly. Water warms up VERY FAST. I would say about 10 to 15 seconds.

    • Worked well. But forces actual HWH to one side
Color: White 15"x18"
Was what I needed just wish the description said or showed that the hot water heater would have to sit over to the right side, looking at it from outside. Plumbed it in the center and had to move when this arrived. Just made me have to do more work then I planned

    • Can't find anything to complain about
Color: White 15"x18"
Great price, great value I love having on-demand hot water and stays that way the only downside is the wire for the thermostat is to short and couldn't really tell until it was installed but I got it temporarily hanging once I winterize it I'm going to pull it out and make the cord longer
