Hello, it takes quite a long time for 45 degrees (3 minutes)! The minimum quantity is about 2 dl. You can't put a feeding bottle in it.

It's really quite quick, you can also bring the water directly to the boil if it needs to go faster (then mix with cold water or something). The appliance maintains the set temperature for approx. 6 hours, after which it switches off automatically when not in use.
I don't know what the minimum volume is for it to work, I meant about 2 litres (it's been a while since we stopped using it).
Theoretically, putting a bottle in it would work, but firstly it's not designed for this (the water wouldn't keep the temperature without a lid and secondly it's unhygienic for the water, which you shouldn't use afterwards to make a powdered milk bottle).
