This is a very convenient appliance. We are in process of constructing our home and needed hot water but had NO PERMANENT place for it yet. This works perfect. Thank you.

It works like a charm

Installed at a beach cottage with no electricity and cold running water. No longer! Works like a charm.

Wonderful product

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.

L5 Tankless water heater great in barn

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.

Only con is freeze protection but the drain valve on the heater should do fine as long as i remember to drain it. Patrick. Glouster Point,Va.

Great Unit

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 and you'll be sold on the heater.

100's of Showers

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. John..
