best bet is to wait until Autumn...or start of winter..when people are feeling cold..
Bigwull is correct ...... unless you plan on using it yourself.
That looks like a fine little wood burning
heating stove .... unless it has coal
grates in it, which it
probably does, then you can burn either.
A picture of the door open will reveal the type of grates and the ash pan.
It will shine up all pretty like with some "stove black".
