If it stands horizontally on the ironing surface on a combustible surface, a fire can quickly break out. If, on the other hand, it is standing vertically on its base, the risk of fire is rather low. However, the ironing surface is then constantly heated up to the set temperature and electricity consumption increases.
The life expectancy of an electric oven is around 13 - 15 years. The life expectancy of a gas oven is around 15 years. The life expectancy of a dual-fuel oven is also around 15 years. However, the lifespan of these kitchen appliances depends on how frequently you use them.
