Research output: Contribution to specialist publicationArticle


In this paper, the efficiency of solar water heating is studied. Experimental data is collected, using a simple toroidal ring in the form of a domestic solar water heater. The thermal efficiency of the system varies between 45%-50%, which is comparable to the values obtained for flat collectors used in the same environments. The cheapness and maintainability of the current unit makes it attractive for remote poor rural and urban dwellers.
