  • Works very well and looks just like the picture. Definitely recommend. Works very well and looks just like the picture. Definitely recommend.
Size: 16L
I’m really happy with this tankless water heater so far. It heats water quickly, keeps the temperature consistent, and we haven’t run out of hot water even with multiple showers. It’s also much quieter and more compact than a traditional water heater. Installation was straightforward and it seems very energy efficient. Definitely a great upgrade for our home. ... show more

  • Need a efficient on demand water heater for an off grid electrical system.
Size: 16L
First of all, I haven't even installed it. It was delivered in good shape. I am in the process of installation. I have no issues with the installation of this unit. If it works as advertised, then I would give it 5 stars. I'm 84 years old and it takes me a little longer to do things-not unlike the Tree Ents in Lord of The Rings. Robert Kunitz ... show more

  • I would buy again
When I turn the cold on in the shower the tank stops working. I guess not enough water flow to kick it on. Since it's just the one shower it might be the shower head or mixing valve. Either way if water is flowing it should kick on.

  • No no Just NO. Sorry excuse for taking people $
Seemed like it was working for ~3 days We just needed to "dial in" the temp (which is VERY hard w/this unit btw) Then just stopped. We tried everything we could think of for 2 more days BUT the clicker wouldn't click. No clicky-no lighty-no hot water 🙄😔😭 New batts 2x/new tank 3x/ checked water flow from pump. Ordered a new pump (were planning on it anyway though) Still no hot H2O!! 2nd unit 😒 Same thing. Amazon helped as they could by getting a refund as company name on tank means zero. That is only a distributor of a mass produced product they personalize per distributors specs. So No. We definitely do not recommend. This is supposed to be "portable" used hooked up to a hose in a campground/RV park & a propane tank. We hung it outside for quick shower or washing dogs so it never moved!! ... show more
