While we are talking about honey and dogs, can I ask: I saw for sale this plastic covered sleeping mat for old/sick dogs, runs on low temp and electricity, and is flexible. I wondered if anyone uses these wrapped around a big honey bucket to warm their honey for bottling?
No, but I have tried the beer brewing ones and they don't work without help. I use a 25w/40w bulb shut in an insulated dishwasher. The dog mats might work if you also contain them in an insulated box, but a light fitting is cheaper than a pet mat.
