We are in the middle of a DIY kitchen fit and (in both sense i e. doing it ourselves and DIY kitchen units) and I have just realised that we need to find an extractor fan for the cooker. We have 110cm space for a cooker in the chimney breast and are going to vent it through a false ceiling to an external wall but I am having problems finding a hood wide enough which will fit into a chimney. They all seem to be the big hood ones. Surely someone on Mumsnet has got a set up with a fan set into a chimney? Quiet would also be good but I assume I can't have everything!
