Review: Only lasts about 5 years, but it's still a savings over a conventional water heater - DIY installation is possible, but it's not for the inexperienced. It requires knowledge of both plumbing and electrical. You WILL have to run new wiring and the plumbing hookup may require some creativity with fittings and sealants. Nonetheless, as an adept do it yourselfer, I'm satisfied with the product. Review: Not a good product. Don't buy. - The appliance worked fine for 7 to 8 months. Now is not working anymore and Atmor customer support is not answering my emails.
