I am building a new house, 2.5Bath with whirlpool tub in master. I have expansion for a full bath in the basement, and will be adding Radiant Floor Heating as well (Basement, Shop, Garage, total of about 3200sqft for floor heating).

I have read on different brands of heaters, and am down to 2 - Bradford White 75Gal 76kbtu, first hr 82gal, natural vent, or Richmond (I believe it is actually a Rheem if my research is right) 98Gal 75kbtu, first hr 135gal natural vent.

I am sure there will be a heavy vote for Bradford, but I am concerned that it may not be enough for both the house requirements and the heat application. Thoughts?
