Smarter Heating & Hot Water

LPS to KW Calculator

Calculate kilowatts (KW) from flow rate in litres per second, temperature difference, and specific heat capacity.

Flow Rate (F) Litres/Sec
Specific Heat Capacity (SHC)
Power Output
83.72
Kilowatts (KW)

Formula

KW = F × (Dt × SHC)

KW = Kilowatts (power output)
F = Flow rate (litres per second)
Dt = Temperature difference (°C)
SHC = Specific heat capacity (kJ/kg·K)

Important: This calculator provides theoretical power calculations. Always consult with a qualified heating engineer for your specific system requirements.
