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!

Perform as advertised

I recently purchased the L5 portable tankless water heater. The unit was received on the day promised. All the fittings were included as advertised. Connections were easy to do and the unit performed as described. Within seconds I had warm water coming out and soon it was hot. I was surprised as to how quiet the unit was.

Teriffic barn shower for my AQHA horses

This is second Ecotemp water heater I've had and it makes it easy for me to rinse off my show horses in cold weather. This second one I purchased has metal shower hose and is much stronger than robber coiled hose - would certainly recommend it for barn use !

hot showers any time from a hose and a propane tank

The Eccotemp L5 is easy to set up and extremely economical--a 5-gallon tank of propane lasts for months. I had a few problems with the first one I bought and the company's support staff was pretty helpful, finally offering me a good deal on a replacement unit when we couldn't track down why my 2-year old unit was malfunctioning--but I am one of those people who is good at pushing products to their limits. I am reasonably sure that if I take good care of the new one, it will last a lot longer than two years. If, like me, you are in a situation where you need hot water but don't have a bathroom and hot water heater, this unit will keep you and your dishes happily clean without a lot of fuss and bother. When I'm living indoors again, I will be checking out their household units for my house, which is currently under construction.
