摘　　要：分析了户用太阳热水器和太阳热水系统工程的经济技术特点,对两者成本构成、项目财务净现值、投入回收期和财务内部收益率等有关指标进行了经济技术比较。分析比较表明,太阳热水系统与家用热水器相比,节省安装占地,与建筑相结合得好,在降低成本,缩短投资回收期,提高经济效益方面有明显的优势。The characters of domestic solar water heater and solar water heating systems are analyzed, and the cost constitutes; net present value, investment recovery period and internal rate of return of them are compared in this paper. The solar water heating systems are excellence in the view of saving installation area and solar water heater integrated building, it also has obvious advantage on cost reduction, decreasing investment recovery period and improving economic benefit.
