Shed insulation and heating question

Sheddie Aiden Hughes has asked this

how do I go about insulating an existing timber T&G shed to allow me to use it during the winter. I would like to fit a eberspecher caravan heater to work in it. Any advise welcome

I know a few of you have heated your sheds can you give any advice to Aiden or the rest of the sheddi.
