40 Gallon Water Heater - Enough for 2 People?
I have a 40 gallon GE SmartWater Heater that runs out of hot water very quickly. I live in a townhouse with my 11 year old daughter, and when she showers (no longer than 10 mins), the water starts to turn cool, and I have to wait for about 30 mins before I can have a hot shower. Considering that only 2 of us live in the house, I'm quite surprised that we cannot shower back to back in hot water. Do I need to get a larger water heater, or could it be a problem? I replaced this water heater about 2 years ago, and it is under a 6-year warantee.
