Abstract This paper presents an analysis of an air/water heater, consisting of pipes, laid in a solid block; the surface of the block exposed to the sun is blackened and glazed, whereas the other surface is insulated, with the outer surface of the insulation being in contact with ambient air. The block can consist of sand (laboratory model heater) (Sodha et al. , 1980) or a south facing wall or roof; thus the concept represents an integration of the heater with the building. The modes of operation considered are (i) when the glazing is not insulated at night and (ii) when the glazing is insulated at night.
