content: Replaced our old tank water heater 2005. We are on our 3rd unit Power Star AE115. The first 2 were covered under warranty but finding someone to replace it was a hassle and each time cost $175 to reinstall. Now #3 has died. I'm done. Back to the old reliable tank water heater. Too bad because I did like the endless supply of hot water. You can not have 2 hot faucets going. So, 3 units in 4 years, not too good in my opinion. Buyer beware!
