This study presents a detailed methodology for evaluating the energy, environmental, and economic contributions of heat pipe solar water heating (HPSWH) systems in various households. The hot water consumption patterns of Perth residents in Australia in one, two, and four-occupant houses are extracted in hourly basis throughout a year. The annual performance of the system is evaluated based on parameters such as saved energy, solar fraction, avoided CO₂ emission, saved money, and payback period. Moreover, an experimental rig is designed, manufactured, and tested. The results show that the contribution of the solar system in meeting the hot water demand is around 99% in summer, while this contribution drops to 36–51% in winter. Almost 387–1146.8 kg of CO₂ emissions can be avoided annually in Perth if HPSWH systems are integrated with the conventional heating systems. In addition, it is shown that the HPSWH system has its most economic justification in households with higher number of occupants. Moreover, the payback period is much lower for houses with conventional electric water heating systems compared to houses with LPG systems.

这项研究提出了一种详细的方法，用于评估各种家庭的热管太阳能热水（HPSWH）系统在能源，环境和经济方面的贡献。在一年中，每小时按小时提取澳大利亚珀斯一，二和四人居住的居民的热水消耗模式。该系统的年度性能是根据诸如节省的能源，太阳能的比例，避免的CO ₂排放，节省的资金以及投资回收期等参数进行评估的。此外，还设计，制造和测试了一个试验台。结果表明，太阳能系统在满足热水需求方面的贡献在夏季约为99％，而在冬季，这一贡献下降至36-51％。几乎387–1146.8千克的CO ₂如果将HPSWH系统与常规供暖系统集成在一起，则可以每年在珀斯避免排放。此外，还表明，HPSWH系统在居住人数较多的家庭中具有最经济的理由。此外，与具有LPG系统的房屋相比，具有常规电热水系统的房屋的投资回收期要短得多。
