    • Great hot water
I had one from another reputable company which had caught fire. They sent another unit which was junk. I did many hours of investigating different companies and the units and this seemed to be well built and reliable. So I installed this one only to say what a difference. This is built so much better and is easier on my pocket. I just got my electric bill and it is also cheaper to run. Wish I would have bought this the first time. ... show more

    • Wasn't right wattage for our house.
Style: 27kW（APOLO 2.0）
Too big of wattage for our house. I'm sure it's a good unit, just didn't work for us. We didn't have the right hookup for it. Sent it back.

In a nutshell, this tankless hot water heater hooks up and heats for a small application. It works fine to supply water to sinks. It was easy to install although does need unusual electrical and was inexpensive. But I would neither reorder nor recommend because this product is stunningly unprofessionally presented. I actually thought I got a counterfeit and checked the Westinghouse site - it isn't counterfeit, they just let anyone license the brand and slap it on incoherent products. Just look at the packaging - it isn't done by a fluent English speaker. ... show more

    • Couldn't be any easier
Style: 27kW
It's a 4 star for now, not saying it wont be a 5 or so later. It is a hassle running all the wires that is probably the hardest thing of all honestly. Once you wire it up and turn the breakers on its really plug and play. Changing the water temperature is super user friendly it was smooth as can be. But that's all good and dandie but from a 60 degree day in a Michigan style basement (if you know you know) the water went into the unit at 58-60 degrees and it took approx. 2-3 minutes to heat up. That is more than reasonable in my opinion all things considering. The only downside so far and I could be wrong but I think it relies on water flow to turn on the unit to heat and the flow has to be significant. I have well water, so my pressure isn't the greatest and that's on me not the units fault. But was taking a shower and the water was wrong until it wasn't anymore. It cut out and went cold on me, but then I went downstairs and the unit wasn't even acknowledging flow. So, I decided to turn the bathroom sink faucet on hot and the shower and then I had no interruptions. All that being said thats my negative but I will update as I break unit it. ... show more
