Think it prob needs re gassing, it lights Up ok on gas and seems to chuck out heat from vent on top when on elec but metal plate inside just doesn’t get cold!(it used to proper freeze up overnight if left on!) It’s destined for the tip tho as I’ll prob just buy new one next year so free to collector (Horsham West Sussex) if anyone wants to play with it! It’s done well tho prob 10yrs old!
