Features

  • Space Saving & Better Performance- It is only 1/4 the size of a 50 gallon tank water heater, yet it produces approximately 4.0 GPM of hot water through 102,000 BTU for both bathroom and kitchen hot water demand. The highly integrated components also provide greater safety from water pressure surges without the need to install an expansion tank
  • Fast & endless supply of hot water- The oxgen-free heat exchanger quickly heats the water to a maximum of 140F in 2 seconds and the hot water is quickly piped through to the shower and tap. No need to wait for the water temperature to heat up slowly like a tank water heater. After that it continues to operate at approximately 4.0 GPM for 40 minutes, which is enough time to produce almost 160 gallons of hot water
  • Steady Comfortable Temperature Control -Benefiting from the calculation and control of the heating power 1000/s by the chip, the temperature difference of the water can be precisely controlled within 2F. The tankless hot water heater has trendy and modern design with unique gray glassy front panel, easy to control the water temperature with LED touchscreen
  • High Compatibility & Easy Installation-You can replace t most tank water heaters ,original exhaust vent, water and gas pipe can be used for Camplux tankless water heaters, only requires only a simple re-layout. This compact size makes it easy to install even in a new house. We recommend that all installations are carried out in accordance with local building and plumbing codes by licensed professionals
  • Durable & Long Lasting- CSA certification in the USA and Canada. Superior safety and durability using the world's most advanced technology. Camplux provide 3 years warranty on heat exchanger and 1 years warranty on other parts

  • works great
Style: Liquid Propane
I live 50 miles from the nearest road on a remote homestead in Alaska. Our water is very cold coming out of the ground and I was a little worried if this unit would be able to heat our water fast enough for a shower. This unit was very easy to install, very easy to set up and the water comes out hot and consistent. Very please with the price and the use of this item. Very good product. ... show more

  • Note This Is Only 1/2" Water Connection
Style: Liquid Propane
Didn't work for me. I live off grid and my water is gravity fed. My water supply is the typical 3/4" and this is only 1/2". It was easy to connect an adapter, but why they would make this 1/2" when most every typical water line is 3/4" is beyond me, because the 1/2" decreased my water pressure to practically unusable. It also said it was suitable for more than one bathroom, and it clearly isn't. This would be more suited to use as a single need, like for just a single shower or just a single sink. I will say it is probably the prettiest and sleekest of all the tankless water heaters I've seen. You definitely don't need to hide it, just wish it would have been 3/4" then it might have worked. ... show more
