SECTION E: HYDRONIC HEATING PIPING

PUMP SELECTION

In order to insure proper performance of your boiler system, you must install a properly sized pump. Raypak recommends using a 20°F Delta T as design Delta T. (Delta T is the temperature difference between the inlet and outlet water when the boiler is firing at full rate). If a Delta T larger than 20°F is necessary, the bypass must be installed and adjusted to insure proper hydraulics through the boiler while still allowing minimum flow to satisfy the safety flow switch. See Table D-1 for flow rate requirements.
