Am currently in the throes of renovating a derelict old hovel (much loved though!). We have had an Aga in the past - which I think is great for old houses. This house will have a large 2 storey extension, including a kitchen/dining/family room. What are your thoughts on whether we should install a big new Aga or a range (thinking Mercury). We will need a new boiler too btw. Anyone's sensible advice very welcome!
