Recursos en línea: Resumen: We performed calibrated side-by-side measurements of the thermal performance of solar water heaters with spaced polypropylene tube absorbers in identical glazed and insulated collector boxes. This was to determine the influence of tube spacing and tube height above the back insulation. A low flow rate (4.32 g s-' m -2)was used. As the number of tubes (spaced over the same aperture)is increased by 76.3
