Water vapour envelops home during cold wave
Last night it got down to something in the neighbourhood of -22 Celsius in London, Ontario. That's cold. This home, heated by natural gas, is enveloped in the resulting water vapour being exhausted at the back of the home. This cloud of vapour is causing frost to form on the roof and eaves.
To read a warning about the use of insulating window blinds, see my post with pictures. We are always surrounded with water vapour but during the coldest days and nights of winter, this water vapour becomes briefly visible.
