热水器防堵塞

家用热水器使用一段时间后，内部易生水垢，影响使用。根据热水器易沉淀和积存水垢的特点，每次使用完热水器后，应先关闭煤气开关，使热水器燃气管道内的煤气全部燃烧完，不致余存。再让热水器内剩余的热水全部流出，直到流出冷水，才关闭进水阀门。这样有利于防止热水器内部堵塞，延长热水器的使用寿命。热水器防堵塞@成齐贤

夫妻上演无间道“美男计”穿帮伤了自己

中年婚变,"铁公鸡"暗算妻子2008年11月2日上午,安徽合肥市某太阳能热水器公司老板娘沈小鱼,带着两个人到杏花公园附近的一个住宅小区推销太阳能热水器。摆好了展台,想到自己已经有十几年没进杏花公园了,里面建设得怎么样了?她把展台交给手下,自己信步走了进去。     

生活一点通

别用热水器里的水做饭一般电热水器和燃气热水器内置的水胆和管道，经过长时间的使用，会出现金属锈蚀和杂物沉淀。水胆和管道还会结垢，水温升高时，水垢中的重金属元素可能会溶出。金属锈蚀、微生物及其代谢产物就会污染水体，不适合直接做饭。

Adoption of technology by the low-income population segment: The low-cost hot water heater case

The employment of means for efficient use of water and energy are being increasingly incentivized, in relation to the sustainability of buildings. In Brazil, there is much concern regarding the difficulty of getting low-income segments of the population to adopt energy-saving technologies. This study provides guidelines for the inclusion of manufactured, low-cost solar water heaters (LCSWH) in low-income housing in combination with environmental education of this segment of the population. Therefore, a group of dwellings located in a low-income community in Campinas SP, Brazil, was selected for installation of LCSWHs, which were assembled and installed by the study population itself, who also participated in environmental awareness workshops. Particularly apparent in the results obtained, was a tendency to reduce energy consumption by using the LCSWH, attributable in part to behavioral changes from environmental awareness; and that the planning, application or organized systematization of knowledge is feasible in low-income housing, provided it is not promoted solely by dependency culture, since the objective is to provide an instrument for self-discovery, mobilization and participation by the population.

Groundwater Citizenship and Water Supply Awareness: Investigating Water‐Related Infrastructure and Well Ownership

Due to increased demands for irrigation water, the availability of groundwater has been a growing problem in Kansas, where the future of the High Plains aquifer is in jeopardy. This article investigates the environmental stewardship of Kansas well owners, a key social group whose protection of water supplies is pivotal to prolonging groundwater formations. My guiding research question is: Does owning a well lead to a distinct form of citizenship? To answer this, I constructed one of the only data sets of well owners used in sociology by surveying 864 well owners and non–well owners throughout Kansas. My findings reveal that well owners are more aware of the state's water supplies than the general population, they express environmental motivations to conserve water, they deliberately conserve water more often than non–well owners, and well ownership is significantly correlated with highly ranking water security as a challenge facing Kansas. Furthermore, a majority of well owners check their well depth and test for water contamination, routines that connect them to their water supply. This suggests that well owners exhibit “groundwater citizenship” and can be conceptualized as aquifer stewards.     

青年水环境保护意识与行为分析

青年是"五位一体"社会建设中生态文明建设的重要参与群体,其态度与行为将直接影响生态环境建设。以洪湖周边青年人作为调查样本,分析青年群体的态度与行为及其影响因素发现:青年人对水环境的认知有待提升,其对相关的法律法规的了解并不全面和充分,对水环境的保护主要是从个人利益视角出发;青年人的环保活动参与程度与洪湖水环境保护行为呈正相关关系等。应通过加强生态环境法制法规的建设与执行力度、加大针对青年群体生态环境宣传力度以及合法推动生态环保组织建设等措施,推进青年群体的生态环境保护意识。     

Territorial Modernity and Public Space: Lessons from the Politics of Water Conflict Along the US/Canadian Border

Conflict over water resources is a major problem throughout the world. This essay describes the long-standing and often successful effort to insulate decisions on how to allot water among contending users, and how to reduce water pollution along a 5000-mile international border. The effort has been fraught with political and scientific complexity. Yet, after more than 90 years of experience, it provides a model that other nations are beginning to examine as relevant to their own efforts to find solutions.     

EVERY DROP COUNTS: A WATER CONSERVATION EXPERIMENT WITH HOTEL GUESTS

We implement a field experiment with hotel guests to measure the effects of nonprice interventions on water conservation and customer satisfaction. In hotels, guests have no direct pecuniary incentive to conserve water, as consumers do at home, where they pay their own water bills. Because hotels earn greater profits when they manage to convince guests to conserve, guests may be suspicious of a hotel's stated social goal of water conservation. By implementing behavioral interventions that address these challenges, we find that our nudges can induce guests to reduce their water consumption, even when no direct monetary incentive is provided. Using post‐stay customer surveys, we detected no adverse effects on customer satisfaction due to these nudges. (JEL D12, I31, Q41, Q50)
