We had the tank installed on 7/30/2009 and it is a 30 gallon tank. Now it is Dec 1 and we have not had hot water for 6 days. This hot water tank is under warranty and is to be serviced by the A&E Sears but they never show up, and get nothing but the runaround when you call Amercian Heaters and A&E Sears. Both have hundreds of complaints against them and even class action law suits. Do not buy this product unless you fully understand it is a piece of junk that can possibly explode. Check out there website Americanheaters.com to see all of the problems these hot water tanks have had or are having. read full review »
