Space and water heating are delivered from a central source to all the houses, using a condensing boiler. 所有住宅的采暖和卫生热水全部由使用冷凝锅炉的集中热源提供。
If an uninsulated tank is filled with steam, the condensing rate due to ambient cooling may exceed the venting rates specified in this standard. 如果向一个非绝缘的储罐内通入蒸汽，在该标准中由环境造成的冷凝率可能超过了指定的排泄率。
