  • Works as intended
Model: RE45K
Small, sleek, affordable little machine. Works as intended, no complaints here!

  • Poor design and function.
Model: RE45K
Had two with problems with each. When finally installed the temperature is not actually hot. Will still use as it is in my garage and is used to clean my smoker grates and clean paint brushes, neither requiring really hot water.

  • Great Instant Heater
Model: RE45K
We installed the heater at our outdoor kitchen and it works great to provide instant hot water. Great Product so far!

  • Relatively low power but gets the job done
My water heater is the same model but looked dramatically different than the pictures (not even the same color). The performance specs and model number are identical so it all works out for me. I hooked up this water heater to a recirculating shower system which I'm working on in my camper. It takes about 5 minutes of running to get the water reservoir nice and warm, in-line with a recirculating pump. I have only taken a few showers but have tested it many times already and it has worked well. ... show more

  • perfect for my job

It would be nice if the power cord was a little longer.

  • Surprisingly powerful
Model: RE45K
I should have paid attention to the 4.5kw aspect of this heater. It really puts out a lot of really hot water. So much so that its too powerful for just one sink. You can adjust the temp but this could clearly run a shower as well as multiple sinks. Easy to install.

  • Broken
Model: RE45K
This item is broken when It came in the mail. And I have no way of returning the item because it's been 2 months since I purchased it. I'm just now installing it and discovered it's broke.
