Since you're no expert, look up the difference between kettle heating into an insulated unit vs electric/gas heating the room. It's cents on the dollar.
I do the same, leave it near my feet under the blanket. When you go to bed you must be 100% sure the cap is screwed on correctly, also be sure you got hold of a hot water bottle from a respectable brand, and you will have no issues.
Helps alot, I usually have my hood up on my hoodie jumper. Aside from that, another one i like to use is while sleeping, I put a hot water bottle under the covers, the insulation from the blanket will keep it super cosy under the covers for the whole night.
