Just as a word of explanation. Our resident expert builder "Peter Pervert" is a known contributer who has posted as Big Burner, Water Services, Legion and several other aliases. He pops up here now and then when matron lets him out of his rubber room..
Just to clear things up Groucho, I am not on this forum in any other name whatsoever. The moderators will be aware of that-!!.
Now- regarding insulation your/anyones home -- My home is as well and probably better insulated than possibly 80% of homes .
Walls cavity filled- celotex in roof space - hardwood d/glazed windows 4-20-4 units -- evry opening window and door draught sealed etc etc .
However - being a 'consciencious builder' I am very aware that ventilation is important -otherwise it causes major problems to the fabric of the house .
I have extraction fans in kitchen, bathrooms and even conservatory. I also am aware that unless the outside air can get in- the extractor fans can not do their job correctly-- which is something most people forget about .
I have no problem with a direct vent in the wall in which a flueless fire is situated. A change of air is good . If a decent 'baffled' vent is fitted and positioned correctly it need not cause a major draught.
It's just basic common sense .
We all have choices and the more information we get the better choices we make .
Now- unless you have installed or lived with a flueless fire- you really are not qualified to make damaging comments regarding safety, efficiency or anything else .
Just stick to what you have seen --and not heard on the grapevine - which as we know is usually comments from people who do not understand the technology and are afraid of change- because it upsets their 'comfort zone'.
