The tankless water heater was value priced which was fine. But the vent stack offered and the return policy is horrible. To begin, they only offer a vent stack for 6" walls -- none for 4" inch walls (you can only offer at Rheem.com, same price and free shipping). So, if you order incorrectly or the product didn't fit, they make you shop in back at your expenses AND hit you with a restocking fee. Together, you get about 40% of your money back for something which is CLEARLY their arrogance. So, but the water heater from them and any of the other product or accessories from Rheem.com.
