Manufacturer reviews · owners of this model, published on the manufacturer’s site

  • This compact unit fit underneath the stairs and serves a 1 bedroom accessory dwelling unit just fine. It was easy to install and seems to be of good quality.

  • We ordered this product through Amazon. It arrived in great shape and quickly. We had electricians install the proper wiring and breaker to accommodate the water heater. We also had them put the tail or plug as some people call it. It is a hard wire plug. I felt more comfortable with the electricians doing that. But if you’re comfortable with electricity, you could do it yourself. My husband did the plumbing and he had the whole thing set up within an hour. This was an added water heater just for my laundry room and kitchen. It has been in use now for over a week and we have had plenty of water. I’m so pleased with the water heater.

  • I was hoping for the best, but sadly this 18 gal tank can't supply enough hot water for 1 washing machine... so theres no MISUNDERSTANDING, no other taps, sinks, dishwasher etc ... JUST 1 WASHING MACHINE and yes ive turned up the temp to 130 .....a waste of money and I can't recommend.
