Hi everyone! Thanks so much for everyone’s replies I will get back to them all.
the boat is a 46ft 13ft wide, back engine room, main cabin which is open plan with the kitchen and front room. Separate bedroom at the front of boat.
As for the stove I am unsure of the make. It apparently came out of a cottage. I’ve recently replaced the glass + checked for gaps ect and nothing of any sort. Below I will add some pictures.
I’ll take your advice and give the coal cage a go. I lived on boats prior and never had a problem with stoves. This one however I just cannot seem to keep it lit. I get the coal burning well then add more with vents slightly open and it just seems to go out :-(!
