tankless hot water heaters
I'm trying to decide between a convential hot water heater and a tankless hot water heater for my new house. The house has two bathrooms and each bathroom has a shower and a bathtub. One bathtub is actually a whirlpool tub. The tankless model I have been looking at provides water at about 6 gpm. Is this less than that provided by a conventional hot water heater? What are the pros and cons of tankless hot water heaters and what do I need to know? There would usually be two of us living in the house but I don't want to run out of hot water if using dishwasher and shower, or washing machine and dishwasher and tub. Any information on this would be helpful.
Thanking you in advance.
