Exact times depend on several factors like the starting temperature and volume of the water or milk, if the bottle is made out of glass or plastic, size of bottle, et cetera. If you leave the milk for a longer time in the bottle warmer, milk can overheat. Therefore it is of importance always to check the milk before feeding your child. In the user manual you will find a table with an indication of the times required for heating up milk. You can find a copy of the user manual on the support page of this product.
