  4. Wonderful product 5 Star Review

    Posted by on 19th Sep 2014

    We purchased one of these for a remote property that had electricity and water. We had 20 family members come up and "camp out" there. We erected a shower enclosure and installed one of the L 5s. It worked great. Way more hot water than we could use... even with a bunch of little boys. It worked right out of the box. I have since bought and installed one at home outside by our hot tub. It works wonderfully.

  5. L5 Tankless water heater great in barn 5 Star Review

    Posted by on 5th May 2014

    This is a super price on a really reliable water heater for the barn. It's easy to use and trouble free. Throughout the season, it used less than one small portable tank of gas and we wash several horses each warm day. Last year I forgot to drain when it got cold and the frozen water damaged it. I like it so much we bought another one this year.

  8. Great Unit 5 Star Review

    Posted by on 16th Jan 2014

    I bought the L5 for my wife's mobile grooming business. We Love it! She has a large portable groomers tub on a dolly I built. I mounted the L5 on a handcart along with a 10 pound lP tank. the dogs love the warm water and the clients are VERY impressed with the setup. I would recommend it to anyone. See the setup in our videos at allaspectsanimalcare.com and you'll be sold on the heater.

  9. Need to shower in the woods??? 5 Star Review

    I go to a 5 day country music festival. I have 3 showers set up for my camp area to use. I also have one running my hillbilly deepsink. In 5 days a few thousand showers are taken.

  10. 100's of Showers 5 Star Review

    Posted by on 14th Dec 2013

    I'm into Rock Crawling I bought an L5 back in 2009 and I take this unit with me on big and small events. I always offer free showers to anyone who wants one. This unit has provided 100's of nice hot showers. The only problem I have ever had is we had to replace the regulator.
    I love it and highly recommend it.
    I just took advantage of the BOGO special and bought a L7 & received an L5 for free.
    I can't wait to try the L7.
