Hello,
I was looking at Grant boilers and see that they can have either conventional flues or balanced flues. They do chimney lining kits but the balanced option is £600+ whereas the conventional flue version is £200+; that's a big difference. Is there any advantage to paying the extra for a balanced flue or would you go conventional?
I had a couple of quotes and the plumbers seem to favour the cheaper option.
I understand with conventional flues you have to be careful with extractor fans. The brochure says the fans have to be installed to BSxxxx. We have a fan and a cooker hood so what does BS xxxx involve? Where can I find and read it?
Thanks. Stephen.
