Abstract
A heat transfer system includes a fluid flow path. The fluid flow path includes a fluid inlet line and a fluid outlet line disposed downstream of the fluid inlet line. A heat exchanger is interposed between the fluid inlet line and the fluid outlet line. Heat generated via a heat generation system is transferred to fluid within the fluid flow path at the heat exchanger. A pump moves fluid along the fluid flow path. Control circuitry of the heat transfer system is in communication with the pump. The control circuitry is configured to execute a scale flushing routine, wherein the control circuitry controls operation of the pump at a maximum pump speed for a duration.

A heat transfer system, comprising:
- a fluid flow path that includes a fluid inlet line and a fluid outlet line disposed downstream of the fluid inlet line;
- a heat exchanger interposed between the fluid inlet line and the fluid outlet line, wherein heat generated via operation of a heat generation system is transferred to fluid within the fluid flow path;
- a pump that moves fluid along the fluid flow path;
- and
- control circuitry in communication with the pump and configured to execute a scale flushing routine, wherein the control circuitry controls operation of the pump at a maximum pump speed for a duration.
