  • Small, low power unit but performs as designed
Style: 6kW
It was a tough call giving this product 5 stars but it performs exactly as designed. However, the design might not meet many customer expectations. The problem is physics. This is a small water heater that can only deliver 6 kW of power to the water. 6 kW is only 341 BTUs/minute. If you do the math, you find that this water heater is only capable of raising the water temperature 40° at a flow rate of 1 gpm. That assumes 100% efficiency (not likely). If the inlet water is 50 degrees Fahrenheit at a flow rate of 1 gpm the absolute best the heater can do is raise the temperature of the water to 90 degrees. That’s pretty chilly water. Note the heat transfer is flow rate dependent. And higher flow rates mean colder water (not good for showers which average 2.1 gpm). For my application this works perfectly. I installed the heater under my kitchen sink which is located a good distance from my 40 gallon tank hot water heater. The inlet water is about 65 degrees at the start of the delivery. With a flow rate of 1.2 gpm I get about 95 degree water at the faucet. The unit takes 15 seconds to heat up. I initially run about ½ gpm which gives me around 110° lukewarm water (after the 15 second heat up cycle) until water from my tank hot water heater reaches the tankless heater. Then Katie bar the door. The faucet water temperature is whatever is programmed into the tankless heater. I have it set for 131° which is scalding hot. If I’m using the faucet intermittently, say every 15 minutes, the water stays pretty warm. The water downstream from the tankless heater comes out of the faucet very hot then cools a bit then heats back up as the water from the 40 gallon tank water heater reaches the tankless heater. Thus my 5 stars. The unit seems well built and its display provides real time water temperature. It is compact and easy to install. All fittings are o-rings minimizing potential leaks. This unit does exactly what the physics allow it to do. ... show more

  • You Get What You Pay For...
Style: 24kW
Beware, this is not warming the water. Never heard of nor used this brand before. But decided to give it a try to 'save money'. BIG mistake. Very frustrating experience. And yes used a plumber to help install it, and trouble shoot it. Powers up, but not heating the water. It's definitely going back.

  • Works fine for 700 sq/ft house in Tampa
Style: 6kW
It will only run one faucet at a time. Piping hot in warm months. Hot enough in the cool months. I run my entire house with it. Sinks are always nice and hot. Shower is pretty good on average. Clothes washing machine is slow to fill, but not so slow that the drum goes cold. Adjust the washer valve so the washer is hot enough. ... show more

  • Great product
Style: 14.6kW
I’ve purchased and installed a few of these and other than having to upgrade the panel it’s easy to install and works great for a single or two person home! I have had no real issues with these at all!

  • my 10 year old one was better
this thing struggles if the outside temp gets in the 50F or below, and in the winter, nearly have to slow the water down about half way to get hot water. my old one lasted 10 years, was very basic, not digital like this one. seems to draw a lot of amps for the work its doing.

  • Pleasantly surprised
Style: 27kW
The media could not be loaded. I was a little skeptical about this and all ELECTRIC tankless water heaters but this thing is awesome! Works great in my 3 floor town house, w/ 4 people no problem. Would definitely recommend! Pros: -easy to install (the actual unit, the wiring is a pain, but I'm a licensed electrician) -ease of use. turns on and just works -compact unit. Now I have more room for activities! Cons: -the wiring terminals are small. Meaning the biggest wire you can fit is #8 AWG (which is what is required for the 27kw) I had #6 wire I wanted to use but unfortunately I couldn't. Final thoughts: Buy it! You won't regret it! Will update later for a change in BGE. ... show more
