1. Actually 3 questions--can you/how do you/should you vent a pyramidal roof with dormers? (PS - I just had to look up the pronunciation of "pyramidal"--I found both pronunciations...).
2. How do I configure for adequate air supply and noise control for a heat pump water heater (HPWH) in a 1400 square foot, tight home in Montana?
And then, I would like to apologize for Steve and his: "A polar bear walks into a bar..."
