Eccotemp L10


The Eccotemp L10 Portable Tankless Water Heater is one of the hottest tankless water heaters on the market! The Eccotemp L10 Tankless Water Heater gives you endless hot water at your cabin, summer cottage, lake home, potting shed, RV, camper, farm or wherever else you need hot water. The Eccotemp L10 Portable Tankless Water Heater delivers up to 2.6 Gallons Per Minute of hot water ranging from 80-145 degrees Fahrenheit: plenty for 1-2 hot water applications running at the same time. The 2 "D" cell battery ignition starts the flame only when water is running, so there's no chance of overheating. It is perfect for off grid or areas where you have limited electricity. The L10 comes with standard 1/2" NPT fittings. The ideal operating range is 20-80 PSI. The system also works great on modified water systems with items such as a 12-volt pump.

Awesome Performing Product

I purchased the Eccotemp L10 LPG Tankless Water Heater for use with a summer outdoor shower I built on my deck. Unit works as advertised! Easy installation; connect a 5gal propane tank, put in 2 D cell batteries and connect the garden hose. A non-stop supply of warm & hot water! I have not needed to raise the temperature knob above 1/3 full, so the water temp should be hot enough for everyone. Quiet, quick and attractive. I couldn't be happier with this unit!

Just got a new one

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.

Works great right out of the box

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.

works well

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

Slick R.V. set up, lots of hot water for all your needs....

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!

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.

I love this water heater

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.

My third purchase....

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.
