  1. Just got a new one 4 Star Review

    Posted by on 18th Jan 2017

    I bought my first one in 2011 and it was pretty much trouble free until 2016. Then two rows of burners didn't ignite so had to get a new one. Sometimes hard to regulate for an inside shower since you control the temperature from outside controls. The installation cost is about as much as the product, but I still think it's worth it because it uses about a tenth of fueling a water heater that is turned on all the time.

  2. Works great right out of the box 5 Star Review

    Posted by on 1st Sep 2016

    The L10 seems to be a perfect fit for our off-the- grid cabin. Fed by a 250 gallon roof top rainwater collection tank and a small battery operated pump, the L10 fired as soon as it saw water and sustained the hot water nicely. I would definitely recommend this untit.

  3. works well 4 Star Review

    Posted by on 7th Jun 2016

    Works well, just takes very little to freeze and destroy. Not very rugged.

  4. Slick R.V. set up, lots of hot water for all your needs.... 5 Star Review

    Posted by on 29th Dec 2015

    Found the need to us my 32 foot three pop outs for temporary living quarters and it had limited hot water with a very small water heater. I plumbed in the L-10 and instantly had all the hot showers I could stand. Life is good again, thanks Eccotemp!

  5. Fantastic 5 Star Review

    Posted by on 6th Sep 2015

    I installed this at my cabin with the flojet water pump and they work seamlessly together off of a deep cycle 12 V battery to serve a deck shower and kitchen sink. I couldn't be happier.

  6. just what we were looking for! 5 Star Review

    Posted by on 21st Jul 2015

    easy to set up. I was having a hot shower within 1/2 hour.

  7. I love this water heater 5 Star Review

    Posted by on 28th Apr 2015

    This is the best water heater for outside use. It is convenient and simple to use anywhere. The Eccotemp customer service people are the best to work with. They are very knowledgeable and take the time to help you with anything. I will recommend this product to anyone.

  8. My third purchase.... 4 Star Review

    Posted by on 27th Jan 2015

    I love this product for quick hot water in my barn for horse bathing, etc. My problem was when the weather would get below freezing. I lost two of these heaters due to internal cracks from freezing. Well, silly me finally read the manual and realized I wasn't opening the drain valve prior to freezing! So be warned that it is essential. Thank you to the Company for giving me free shipping on the replacements.

    Posted by on 14th Oct 2014

    This unit was put in a stationnere camper, people can not believe how fast and hot the water gets. I know of four or five people who are planning to put one in. We love ours because you never run out hot water and all we do is turn on the hot water..J.BHudgins
