• I'll try find a suitable PTFE cable

    Can be hard to find in large enough sizes for speaker wire. If you can find a cooking thermometer, take a measurement of the actual temperature in the location you're going to run cable, you might get away with 180°C silicone rubber which is easier to find in suitable cable forms as it's used more in automotive whereas PTFE is mostly used for small internal equipment wiring. If you're a tart about the actual wire form, you can roll your own by pulling bare conductors into PTFE or silicone rubber sleeves, which are easily available in a wide range of sizes. https://www.hilltop-products.co.uk/ are #tester_approved for such things.

  • it's all seeming a bit complicated - I think I might just bore two holes in the cupboards either side of the fireplace, and drop the normal cable into the underbuilding then thread it back the other side...
