North has an interesting piece (H/T Autonomous Mind) about the widespread failure of condensing boilers in the UK this winter and last. The problems have been caused by the condensate pipes freezing up in cold weather. Unfortunately condensing boilers seem to have been pushed hard by the government in one of their fits of eco-madness.
A few years back I discussed condensing boilers with a local plumber - an Englishman - who couldn't understand the Scottish fixation on combi boilers. Now I wonder if perhaps the Scots didn't just know something he didn't.
