| Domestic hot water consumption in the building energy consumption is part of can not be ignored. As the main clean and renewable energy, solar energy is being increasingly widely applied and studied. Solar hot water technology as a process of building energy efficiency technology, is being widely used at present. For different solar hot water system, should be reasonably used in actual engineering. Solar hot water system suitability study is of great significance for building energy conservation. The present study few based on the measured.This study based on the experimental research of solar hot water system, understand the running status of the system. Solar hot water energy consumption model is built, and calibrated based on measured results. Simulation analysis of the water filling water strategy, user mode, the user’s water consumption, the collection efficiency, pipe insulation, systems and other factors that affect the energy consumption of the system, system suitability analysis conclusion is given.Finally the research results show that centralized collection hot concentrated heat accumulation type solar hot water around a third heat lost in the system. System of water consumption, the way of filling water, heat preservation, collection efficiency, the system will have an effect on the system energy consumption, and should be considered in design.
