Hi all,
A friend of mine has a terraced house and in the bathroom airing cupboard is a combi boiler fixed to next doors wall and apparently it is making a noise akin to an aeroplane when it's on and the old dear can't sleep at night due to the noise. The other night her son was pounding on her door and shouting obscenities at her to turn it off. The boiler was already installed when she moved in 8 months ago. When the boiler is running I can hardly hear it in the bathroom so I can't imagine it's as loud as they claim next door. Is there anything that can be done to quieten it down without major work and cost?
Thanks.
