After two years, repair of the firing chamber might be necessary for an oven which has been used intensively. Regular cleaning of the baking chamber after baking is always required.
Resources needed in use:
Charcoal or charcoal briquettes as fuel.
Problems and limits:
Compared to electric oven, there is a need to get used with charcoal oven in regulating temperature for perfect results.
