I have a gas heater in my greenhouse which is 8 feet by 6 feet with high
eaves. However, I do get a draught which is coming from the door. My
greenhouse is pretty new and I do not feel like buying a new one. Can
anybody advise as to what I can do to stop the draught, I have tried to
adjust the door but it is not very easy.


You need a draught, or rather you need a supply of air and someway of
getting rid of the combustion products
Find out where the draft is going then its path this should cut down
the strength of the draft, what ever you do DO NOT stop it all or you
will have a great build up of carbon monoxide.
