Style: 27kW
Love this tankless electric water heater. I replaced one I had for 17 years. Different brand, but I think this one may work better, I'm hoping. I hope this brand will last another 17 years for me, or at least out live me, lol! Right now, I'm very pleased with it. Heats up pretty well!

  • It'll do, and then some
Style: 18kW
The cost isn't the worst, but 300$ is on the higher side of midrange pricing and may be bit pricey for something as old as my RV trailer. Oh well, it is what it is. It is a pretty lightweight unit, a pleasant surprise as well as rather important to minimizing the overall trailer weight. Installation isn't hard, I'm a (medically) retired carpenter, the basic plumbing and electrical skills I've picked up along the way are more than enough for this simple task. The manual is so well informed it could also be a functional teaching, tutorial manual also; good manuals make good impressions on me, and poor to bad ones chafe me like a deliberate insult so I make a point to include such evaluations in my reviews. This is another component for my camper renovation project. Overall, it is likely to be more than may be needed but that's better than not enough. My '69 Coachman I'm converting to serving as a combination field office, mobile lab (with a small sleeping nook) type of configuration for my archeological pursuits; from cleaning artifacts to shower capacity for a crew, hot water is a virtual rare commodity out in the field. Another factor in the process is my medical issues, hot water is crucial for managing it all, and in the field, this will be even more important. No doubt I won't be the only one such is applicable to. It will probably be a few months before the trailer is ready for this install, just depends on other elements, but if I find any problems with the process (that are related to this unit) I will definitely update/edit this review accordingly. ... show more

I am glad I purchased this hot water on demand unit. It works extremely well and appears to be a higher quality machine than others on the market I have researched. I certainly would purchase it again.

  • Excellent service
Style: 27kW
Had an issue with the water heater, called first they asked me to check out a couple of things I did. They checked with their engineer. A day later they texted me saying a new unit is being shipped, got it the same day. Installed it and is working fine. Speedy good communication that’s what I call great customer service. ... show more
