I am considering installing a power vent gas water heater as part of a
changeover from electric. I know they tend to be noisy, but am wondering about
people's experience with them for dependability and cost effectiveness. The
alternative would be non-powered direct vent, but I would have to core through a
cement wall to install it, and move a main water pipe to put it where the
origional is. Also, are different brands better than others?
