I have the same exact thing your describing. A long ranch house with great distances between the heater and the faucets. What I have com eup with is water heater zones. I will have 3 units in the house. One directly under the main bath which also has a master bath behind it, a second unit which is tankless right by the washer/dryer and about 10 feet from another master bath room with a whirl pool tub and shower. The Tankless is superb for the whirlpool since it provides constant hot water for a large tub like mine, the third unit is a point of presence unit under the kitchen sink which was found to be the most difficult to get hot water to from either heater due to where it is in relation to both units. The big units are both gas and the POP unit is electric and is designed for just one sink. The tankless units are great and highly efficient IF they are properly placed in relation to the outlet you are getting the hot water from.

Have you ever wondered why they call them hot water heaters? If the water is already hot, why would you need to heat it?
