I have recently bought a house with an old tirolia stove and would appreciate any advise on running it. Up to now it is hit and miss I have had the chimney swept and have cleaned it out but sometimes it smokes especially when just lit and sometimes it heats the oven and other times the oven hardly warms at all. When it gets going it's brilliant heating radiators as well. I feel like I am fighting a loosing battle with it and no-one has the info that I need.
