L5 portable water heater.

This little guy makes all the hot water we need for our off grid cabin. We have an indoor shower, a kitchen sink plus a bathroom lavatory. Its connected to the plumbing by two washing machine supply hoses. I constructed a shelter with a hinged door to protect it from the weather. If you have a lot of incoming water pressure I suggest an inline water pressure regulator from Wal-Mart or RV supply house. No problems with hot water supply.

This product ROCKS!

We recently purchased the L5 heater to use for washing sheep and goats for livestock shows. We absolutely love it. It is easy to use and makes a huge difference when washing show animals in a cold barn. We recommend this product; it works great and the price is very reasonable. We shopped around prior to purchase and this is definitely the best choice.

Great product

Works as advertised. Low pressure and highest temp will provide instant scalding temperature - be careful - start with high pressure and low temp. Had a bit of an issue with the hose provided but they sent me a new one. Cust Service is excellent.

Love it. This is the 3d one we've had and will always have one as long as they are made.

L5 portable hot water heater

Well made unit. Made in China if your wondering. Unit comes with pretty much any fitting you may need. Even Teflon tape. All fittings seem top quality. Shower wand has 3 settings so your assured of finding what works for you. The jet spray settiing is more than equal to washing thick hair. On time for hot water is mere seconds. There is a surge of scalding hot water if you pause the shower for a minute and then turn it back on, so be aware of that. Can be a real issue for children or the elderly. Fit and finish on the unit seems top notch. I bought mine direct from the manufacturer for less, so something to consider. At around 14 lbs, the unit is easy to carry, esp with the top mounted carry handle. We use this for boondocking in our camper. We use a 12v FloJet 50 psi pump and a 5 gallon bucket for water. We've used spring or lake water to take showers. Pair these 2 together and you have a really handy item. Everyone likes a hot shower at the end of the day. We also use an in line FloJet strainer to keep any debris out of the entire system. So far, this unit has proven very dependable, thrifty on propane and very user friendly. Cant recommend it enough. The uses are endless. We basically set the temp and water pressure, and it seems to work for most everyone, so your not messing around with the controls. All connections are straight forward with all the fittings clearly marked. Another words, pretty much anyone can set this up in minutes and be using it.

Great Outdoor Shower

I had my other one for several years and it was great! It's used in northern Minnesota and it got left out during a very sudden cold snap (sub zero) before I could properly drain it for the season and some of the coils burst. I was more than happy to replace it without even shopping for another brand or model. Nice hot shower after a day of playing at the cabin!
