Webperature drops also reduces flow rate, which in turn decreases circulator size and power requirements. In summary, the relationship between the heat output of a hydronic circuit and the flow rate passing through it is not proportional. Neither is the relationship between the circuit’s temperature drop and the flow rate through it. Webq = water flow rate (m 3 /s) h = heat flow rate (kW or kJ/s) dt = temperature difference (o C) For more exact volumetric flow rates the properties of hot water should be used. …
