i currenly have a fairly new 40 gallon gas fired hot water tank in my home.
since i live alone, you would think when i come home from work, i could take a nice hot shower or bath, but there is never enough hot water.
i was told that the water in the tank cools during the day when no one is using water, and all i need to do is install a hot water insulating blanket made to keep the water from cooling so much.
the problem with this remedy is that the operator's manual says not to use a insulating blanket on this tank.

can anyone give me any suggestions?????? the tank is only about 4 yrs old and in a heated basement.
