  • Very Good Product!
Style: 14kW
I am so happy with my new under the counter hot water heater that was installed in my kitchen. I fully expect to see my water bill come down as I had to waste so much water just waiting for it to get hot at my sink. The unit only takes up a small amount of space in a cabinet and is so worth the cost to get hot water in just a few seconds. Thank you for a wonderful product! ... show more

  • Works well
Style: 4500W
We received the new tankless water heater, heated it, and installed it. This was a replacement for one installed approximately 6 months ago. Worked perfectly the first time. Purged the system of all air and turned on power. Had hot water with no issues. Set the temperature at our desired level and tested. Been in for 3 days, and we immediately noticed the difference. The old one had flow issues. Had to reduce the flow so much that it was almost a trickle. This one, on the other hand, worked as expected immediately. I washed dishes and found the water was so hot we had to use cold water so my wife could rinse. We have no regrets other than wishing we had ordered this one to start. I would not hesitate to buy this one again. ... show more
