A source of thermal energy (heat)  with a reference to location in 3D space.

The quantitative value is given by the pace of thermal energy variation (production or consumption) per unit time:

W_H({\bf r}) = \frac{\delta E_H}{\delta t}

The total volume of Heat Source contained in a given volume  can be calculated as:

W_H({\bf r}) = \int_{\Omega} q_H({\bf r}) d V
