In a multi-purpose system, which load takes priority?

Explanation:
In a multi-purpose system, domestic hot water takes priority because it’s an essential, time-critical demand. When hot water is drawn, occupants expect immediate hot water, so the control system directs the boiler’s energy toward heating the domestic hot water storage or coil first. Only after DHW demand is met does the system allocate energy to space heating or cooling. This priority ensures a reliable supply of hot water even if other loads are calling for heat or cooling.
