    Head Feet Refresher

    Can't remember...when finding the head feet of a given circuit do you add all component and pipe length values together or is the head feet of the circuit dictated by the point with the greatest value?

    Example (at whatever GPM):

    elbow = .25
    ball valve = .25
    zone valve = .50
    DHW tank coil = 6

    Head feet is equal to 6 or 7 (6+.25+.25+.50)?

    Head Loss

    You add the head loss for each fitting, valve, and pipe length in the circuit. In your example, the head loss would be 7 ft.
