  abstract	= {The use of solar heating systems is a way of exploiting
		  the clean and free energy from the sun. To optimize the
		  energy gain from such a system, where the main input, the
		  solar insolation, is an uncontrollable variable, good
		  models of the system dynamics are required. Identification
		  methods are often either highly specialized for the
		  application or require an extensive amount of data,
		  especially when the dynamics studied are nonlinear. This
		  paper shows that by application of a new recursive system
		  identification technique, a small scale solar heating
		  system can be modeled with very little data, without having
		  to tailor the model structure to the application.}
