Hi, I apologise in advance if this isn't appropriate for this site: Is it possible my peculiar neighbour is deliberately firing off his boiler flue when I am sitting beneath it on my doorstep? He does vindictive things that he can't be directly accused of. We are in a two storey block of flats and he lives directly above me. His fuel meters and boiler flue are right outside my front door but I don't know where my flue is yet so I can't experiment. I feel like I am losing it, like Inspector Clusoe's twitchy boss. When I sit on the step during breaks, letting my cats out (it started this summer), after a little while his flue inevitably fires RIGHT up and clanks and lets out huge power plumes that smell of gas. It would be just like him to turn his hot water on full to make it steam or something - is that how it works? Could he control the output, making it go full pelt so as to interfere with my moments of peace? Or is this paranoia? It's the kind of little games he plays, he is like Gollum and he keeps all curtains and blinds shut at the front where he can peek at what i'm doing out there. Cheers now!
