Ands guys, When I move my gas hob as discussed below, I am also installing a new Chimney style extractor. The current extractor is a built in type that is vented straight out the back though the breeze block/external brickwork.
When I install my new chimney, I'll need to make a new hole for the exhaust. I can't use the existing hole since I do not want the ducting kit to be visible, I want it to vent out inside the metalwork of the chimney itself. My question is do you think it will weaken the walls considerably with me making another large hole so near to the existing one (which will be concreted in)? Or should I just use extraction filters and forget about venting outside?
A bit unsure. I could redesign my kitchen so the hob is in the same place if need be. Not really what I want to do though....
