excellent product

I was able to borrow one from a friend prior to purchase. I am very pleased with the amount of water flow and temperature. I purchased 2. One for my out door shower and one for my RV which would take 40 min to heat 10 gallons. Now I have unlimited hot water in 25 seconds. The pilot will blow out if the winds are high which is easily rectified. Very happy with the amount paid.

Wonderful product

I just returned a similar item from Camp chef because it didn't work and got this. So far have used it three times and I love it, specially it works great without any pomp. I got a gas usage meter for my 20# tank so I will be able to replace the tank in time. I just wished there was a "battery low" indicator on the unit. Other than that it is a wonderful product.

Excellent product!

I live on a boat and use this heater for all my hot water needs. It's very reliable with no problems on the salt water. They last me about three years with use several times a day. I keep it on the outside rail. If I kept it inside, it would probably last a little longer. I added a "T" with a inline ball valve and hose bib on the output side of the unit. This allows me to better regulate the flow and temperature. The hose bib lets me attach a short hose to wash out the cockpit. All in all it's an excellent unit that is very well priced.

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.
