i like to see around .5 total eternal static, if its higher there is a restriction( in duct, in filter, in coil), if its low there is to much leakage in duct
FYI, had one last week on a 16 seer A/C was .82 with pleated filter with blue filter .52
same on a rooftop .68 with pleated filter, .49 with blue filter
im begining not to like the pleated filters
why is this important, comes down to cfm and the energy the motors use the higher the static pressure the more energy is used to move the air
hope that helped

I would suggest using top supply bottom return Rob . Feeding through the bottom the fluid will release heat the colder water going back across top will effectively rob some of that heat back . It is a small number but it is a number nonetheless . This can be seen in the output numbers for Heating Edge 2 baseboard from Smiths .

And yet, air is a fluid by definition.

"Any substance that flows is considered a fluid. This includes such things as water, shampoo, sunscreen, and even honey. Although not necessarily obvious, even gases, such as air, can be classified as fluids."

Get over it Charles, a boiler can be called a furnace.

Gases are "fluid" meaning they can have natural movement. They are not "Fluids" unless liquefied. Different definition of the term "fluid"

Just to be clear -- this is a male NPT 'half nipple' protruding from the tank? Is there enough room to cut and re-thread it? You'd need space for a pipe wrench or some kind of good grip below the threader.

I am sure I have a manual somewhere at the training center. I will be there tomorrow so I will look and get back to you.
