    You can say that again, I do mostly repair work but do some residential A/C and oil boiler rated work too. General installations for the most part are nothing more than average, with alot of systems downright poor in their layout and installation. It appears everything is governed by price, so much that homeowner needs are for the most part, totally neglected or basically DEAD last on the list of concerns. What I really don;t like is telling the HO why they have so many problems or what a good installation with good equipment could do for them. It really pisses me off....sorry for the venting.

    Size it to the heat loss. Period.

    Does that statement also hold true for a boiler that modulates between 20%-100%?
