Try a socket as it’ll be less fiddly than a wrench and also has a lot of thermal mass so it won’t get too hot as you loosen the nozzle. I crack it loose with a 1/4" ratchet, then remove the ratchet from the socket and spin the socket and nozzle out by hand. You also don’t need to be super hot, maybe 180C or 190C and you can shut the heater off once it’s cracked loose (then turn it on when threading it back in). Gloves aren’t a bad idea either.
I apparently need hot gloves, I tried without them but burnt my finger and possibly graunched the spanner.

A socket? I will consider buying one along with gloves, thanks.
Not sure what you call them across the pond:
