The way to translate your problem to a dynamical system that is
considered in model reduction, it is necessary to introduce many inputs
(along the heat source path). That is:

p(t, x) = Sum_i p(x)*u(t)

where inputs functions switch each input on and off consecutively.
Whether this will be an efficient solution, I guess, it depends on a
problem in question
