全球：屋面收集雨水与烟囱的矛盾

当屋面收集的雨水作为饮用水，这个问题并没有得到很好的解决。但问题不大。

There have been consumer reports of contamination, including tainting with creosote, of rainwater collected from roofs that incorporate flues from wood burners. While a range of hydrocarbons could be deposited on roofs in the vicinity of such flues limited testing in one survey (Victorian Department of Natural Resources and Environment, 1997) did not detect concentrations exceeding guideline values in the Australian Drinking Water Guidelines. Nevertheless, it is suggested that where possible rainwater should not be collected from that part of a roof that incorporates a flue from a wood burner. In addition extra care should be taken to operate wood burners correctly and to only use appropriate fuel.

替代的方法是：

1，烟囱那块屋面的水不进入收集系统。
2，冬季点火期尽量停用收集系统。
3，坚决不燃烧有害的东西，比如报纸等。
