-3°c and the water is frozen again.

Hi everyone, I'm in uk and we're just now getting the minus temperatures at night.My buns,flemish giants, have an outdoor shed with different levels.I've tried changing the water bowl position,heating the bowl before I put it in,putting it on a pile of newspaper, straw and the water still freezes. Does anyone have any ideas or know of any safe gadgets I could get to use please?
Thankyou.

There are heated bowls or bottles. Maybe something similar to this in the link below. Though anything with wiring needs to be well protected from bunny teeth.

Heated small pet water dish

Or if you can't use something electric, maybe a Snugglesafe heated pad under the dish would be enough to keep it from freezing til morning.
