Tis GOOD to hear you have a nice draughty house cos no chimney will work properly without draught or draw!! You will need to get it checked for leaks and condition as mortar is affected by certain things you burn!! I would just get some smoke pellets and check yourself for leaks first before you call "experts" . Trouble these days toooo many regs and insurance clauses on new works carried out in the home no matter how new or old it is. .
i would love a wood burner i can get as much wood as i can burn, i have a coal effect gas fire been bost 2 years....... wonder if i can put a burner in it's only a round metal flue not a chimney though, trouble is bet it would cost a bomb.
Ricky: If a flue is outside it has to be insulated / double skinned, or the smoke condenses on the inside wall and forms tar, with possible risk of a fire. Google the regulations and you will find what you need, but if you've got access to free wood it might be worth the effort.
As far as regs, just do it and deny it. What cack I ask you. Same with wiring - one minute I'm completely competent, next minute, jobs from thin air legislation says I'm a bungling ameteur. Same time I'm designing lightning seperation for radio installations on HV pylons. FFS. Yes, burn unseasoned wood and have a chimney fire if you want, but a flue doesn't protect against ignorance - you'll still have a fire. BUT if your flue is just that, and not a chimney, as such, you CANNOT have a proper burning stuff fire - it's totally different.
I know more about chimneys and log burners than I do late Bays...read Approved Doc J from your local building control, this tells you everthing you need to know. http://www.planningportal.gov.uk/buildingregulations/approveddocuments/partj/approved hope this helps
As a qualified plumber/ gas fitter. Not an engineer, but still took me four years to get a level three plus the work on site. Then the gas which needs to be renewed every five years as things change, IE BS standards, building regulations. Consider myself to be reasonable intelligent but would still not fit any appliance without exprience. At the very least get a qualified chimney sweep to sweep and perform a flue flow, they will also check the pot as even they can affect the flue pull. Yes there many dodgy fitters out there, but where do you draw the line, doing your dentistry or surgery. Get this wrong and people will die.
Part of my business when i was building was Georgian / victorian house renovation , the first thing i would suggest when inspecting a cusomers damp riddled home was to open up the chimneys , have them swept and light fires , it would amaze them how their homes dried out and because they are usually still lime plastered and have lime mortar , they could watch the warmth of the fires pushing the moisture from the inside of the house to the outside through the mortar , these home were made to breathe and open fires are their lungs . i did quite often put woodburners with class A liners into them ,but they never quite did the job of a open fire because the liner is sealed at the top - no airflow . Modern (cement based mortar ) pointing, seals the building but stops this process .
I had a outside flue and was suffering tar/draw problems ,this year a built a chimney in the middle of the house and the flue goes up and it is 100% better....we also have a fan that draws hot air and circulates it around the house... I did do loads of research and found lots of dodgy companys like http://www.fireplaceman.ie/twinfluesystems.html http://www.fireplaceman.ie/projects.html we have carbon monoxide alarms in every room...be carefull... 8)
