使用饮用水进行空间供暖和水龙头的组合式暖风空间供暖和饮用热水系统称为强制暖风饮用水源空间供暖（PWSSH）系统。本文描述了自1980年以来在俄亥俄州安装的数百个代表性系统中的五个。回顾了与传统的气体空间加热和水加热分离设备相关的运行经验和能耗。还讨论了安装经济性和当地规范验收要求。运营经验总体良好。PWSSH设备已被证明是提供某些所有设备转换的最低成本方法- 电气住宅采用燃气空间供暖和燃气热水供暖。对于本文描述的五个PWSSH系统，空间加热和水加热的耗气量小于具有类似效率和/或AFUE额定值的单独燃气器具的耗气量。单位:I-PCITION:研讨会，ASHRAE交易，1987年，第93卷，pt。田纳西州纳什维尔2号

Combination warm air space heating and potable hot water systems employing potable water for both space heating and for the taps are referred to as forced warm air potable water source space heating (PWSSH) systems. Five such systems representative of several hundred installed in Ohio since 1980 are described herein. Operating experience and energy consumption relative to conventional separate gas space heating and water heating equipment is reviewed. Installation economics and local code acceptance requirements are also addressed.Operating experience has been generally good. PWSSH equipment has proven to be the lowest-cost approach to providing conversion of certain all-electric residences to gas space heating and gas water heating. For the five PWSSH systems described in this paper, gas consumption for space heating and water heating was less thanfor separate gas appliances with comparable efficiency and/or AFUE ratings.Units: I-P
