The invention relates to equipment for heating a liquid by solar energy. The device comprises an assembly of glass bottles 1 which are perforated via the bottom 2 and nested in one another in the region of the neck 3. A fluid circulates in a number of metal tubes 4 which run through the assembly of the stacked bottles. Sleeves 5 support each bottle via the inside of the neck and also serve the function of calorific accumulator. A plate of corrugated sheet metal 6 makes it possible to keep the bottles aligned while a piece of plexiglass 8 covers the support frame 7. The invention will be used advantageously for carrying out more high-performance heating of a liquid by solar energy than known devices. <IMAGE>
