燃气热水器国家能效标准修订版即将实施

Revised Version of National Standard on Energy Efficiency of Gas Water Heaters Will be Implemented Soon

燃气热水器和采暖炉是大中型城市家用燃气耗能最大的产品之一,GB20665《家用燃气快速热水器和燃气采暖热水炉能效限定值及能效等级》国家能效标准首次发布于2006年,2007年7月1日正式实施,2008年3月1日实施了能效标识,标准标识实施大幅促进了企业对节能指标的重视程度,极大地推动了我国燃气快速热水器和采暖热水炉行业能效水平的提高。2013年该标准列入修订计划,修订版于2015年5月15日发布,即将于2016年6月1日实施。本文简要介绍了标准修订的背景、标准修订后的主要技术内容,以及与日本、欧盟同类标准的能效水平比较。

Domestic gas instantaneous water heaters and gas fired heating and hot water combi-boilers are among the product categories that consume the biggest amount of domestic used gas energy in large and medium size cities. GB 20665, Minimum allowable values of energy efficiency and energy efficiency grades for domestic gas instantaneous water heaters and gas fired heating and hot water combi-boilers, was first published in 2006, and implemented on July 1st, 2007. The energy label system for which was implemented on March 1st, 2008. The implementation of the energy efficiency standard and label for gas instantaneous water heaters and gas fired heating and hot water combi-boilers has helped enterprises to attach greater importance on energy saving indexes, and substantially promoted the increase of energy efficiency level of the industry. The revision of this standard was included in the 2013 national standard development and revision list. The revised version of this standard was published on May 15 th 2015, and will be implemented on June 1st 2016. This article briefly introduces the background of the revision, the main technical contents of the standard after revision, and the comparison of energy efficiency level among Japan, EU and China on energy efficiency standards of the same category.
