Wanted some real world feedback from the fine readers out there regarding hot water tanks. My 40 gallon gas fired unit is just starting to leak and needs replaced. I need some feedback on tankless water heaters as I've heard they don't keep up as well with demand as storage types. Everyone and their brother tries to sell you on them but I'm kind of old school. I also have 3 kids,2 of them teenagers, so between the shower, dishwasher and washing machine the tank gets a good workout. Thoughts, opinions, experiences?
