  • Easy hook up. Very happy
Style: 8 Gallon
5-10 Seconds hot water is great, not drawing 20 - 25 seconds cold water to get hot water. Very easy hookup if you have any plumbing experience. I used Pex/shark bites. Also put whole house filter on my kitchen faucets on hot and cold side and connected refrigerator into it also. I did leave hot water line coming from other tank in case anything happens. Added shut offs and can be turned on if needed. But good cooking water at sink, hot or cold. Filtered before refrigerator helps give longer life of refrigerator filter. Now not paying to heat water that’s getting wasted getting to sink and staying in line. I’ll run lines every now and than to keep lines in good shape. ... show more

  • Great So Far
Style: 4 Gallon
Installed easy, does what it claims to do. Our kitchen sink is 60+ feet away from boiler. 2ft walls on arctic slab meant a long wait for hot to get there especially in Northeast winter. Wish I did a long time ago.

  • What should of been a hour job has turned into a complete cluster.
Style: 8 Gallon
Not happy at all. Need to know if the fittings on the water heater are metric treads. Been to 3 places and no one carries the 1/2 inch hook ups I need. There is no name of manufacturer or tele number to call for info the instructions are a joke .

  • easy to use
Style: 8 Gallon
This has been the perfect hot water heater solution for my detached garage! It is well made and high quality all around, and it was relatively simple to install. It is a compact size and provides plenty of hot water for my particular application. So far there has not been any leakage or other issues at all, and it has been working great to heat the water quickly and efficiently. Overall, I am very happy with this product and would not hesitate to recommend it! ... show more

Ok, it’s been plugged in for a week now and to be honest we’re extremely happy with the product so far. Pros: Str8 forward instructions, easy to read and say to follow. Labeling easy for a child to understand. 8G is the perfect size for the large utility sink and soon to be a beach shower attached. Dimensions work out perfect for the area used. Cons: make sure you can convert Fahrenheit to Celsius. Plug looking thing on the back side????? Understand it’s only been a week. ... show more
