If the calculated outlet water temperature exceeds the safe boiling point, the heat gain rate is recalculated based on the temperature rise limited to the safe boiling point. The adjusted heat gain rate uses the water heat capacity, temperature difference, and volumetric flow rate. The factor of 1000 converts the water density from kg/m³ to proper units.

\begin{equation}\label{eq:water-heating-steam-adjusted-heat-gain-rate} \dot{Q}_{gain,adj} = 1000 \cdot C_{p,w} \cdot (T_{bp,safe} - T_{w,in}) \cdot \dot{V}_{water}\end{equation}
