DOE Heating Capacities are shown. Where the boiler and piping are in the heated space, the boiler may be selected on the basis of the DOE Heating Capacity. Where a piping loss and/or a pickup loss will exist, add this loss to the building loss to determine the total heating requirements. Where a piping loss only will exist but cannot be calculated, multiply the calculated building loss by a 1.15 factor to determine the total heating requirement.
*For runs in excess of 50 ft. consult local or national electrical code.
Maximum Allowable Working Pressure: 30 PSI (Water Only)
