Description

Calculates power in kW from a difference temperature and water flow given in m3/h.

Formula: (TSupply - TReturn) * Water flow * 1.0 * 4.18 / 3.6

Heating coefficient for water 20 - 100 °C = 4.18 kJ/kg*K

Scale factor from m3/h to l/s = 1 / 3.6

Density for water = 1.0 kg/l

Inputs

(Real) Supply temperature (°C)

(Real) Return temperature (°C)
