A combination of solar concentration, downward heat transport by steam and segmented water store provides a new type of solar hot water system suited to a predominantly direct sunlight climate. With up to eight hours average sunlight per day in most Australian cities a fixed non-imaging concentrator can provide efficient steam generation. Steam is an effective means of passive transfer of heat downwards to a ground level water store. A segmented water store allows more efficient utilization of stored heat and lower night time losses. This new type of solar hot water heater is described and the measured performance during the winter period in Queensland is presented.
