I love my Rheem water heaters. As a property manager I find myself needing to order water heaters all too often. But also, as a property manager I see the long term effects of Rheem tables heaters. My oldest is probably seven years old and still going strong. But this review is supposed to be about “Tankless Water Header Depot.” They are consistently the best deal, and they ship quick enough that I can usually accommodate a water heater failure without extraordinary inconvenience to the tenant. As far as warranty issues, I have yet to have a failure orShipping damages that would need to go before the store.
