apologies for a rather non-DIY question but this is unfortunately a tad above my knock-down-and-reconstruct-walls competence :-( ...
We have a three-year old bog-standard two-storey four-bedroom Persimmon house without a chimney, and now we're looking at the possibility of adding a multifuel stove in the livingroom, which of course will mean we'll need a proper chimney, probably with an external chimney breast.
I'd like to appear to be educated before approaching the contractors, and any thoughts about what I need to look out for would be highly appreciated.
My requirement is quite simple: I want a contemporary-style multifuel stove in livingroom, capable of being connected to the central heating system. It should be a nice and modern focalpoint, and heat the house :-) .
From there it gets complicated: I've read up on the various options which seems to leave pumice liner or double-skin liner for the flue, with pumice liner "better" but more expensive to install. A brick or block chimney breast "attached" to the external wall should not cause any headaches (the roof ridge is horizontal all the way and the gable end is exactly where the chimney would rise, and is the highest part of the wall/roof).
I've also picked up the BR Part J, and ordered a hopefully-relevant Amazon book: (Amazon.com product link shortened)
Plus the usual Google searches and some useful info/"questions to ask the installer" from here: http://www.ourproperty.co.uk/guides/chimney_builders_repairers.html
I also intend to contact some of the chimney product manufacturers such as www.schiedel.co.uk, www.topstakchimneys.co.uk
1) How much would the construction of an external chimney itself typically cost, would it normally be of the order of £5k, £10k or £15k, if done completely by a contractor/builder? 2) What parts of this are within the reach of a capable DIY-er? Anything or would the potential savings/risks not be worth it? 3) What should I do/be aware of in order to keep the costs down, but not compromise on the safety and performance of the chimney? 4) Any other hints/thoughts...?
Thanks in advance!!!
