Energy Unwrapped with Mick Wall
Aug 26, 2026 · 1 hr 32 min · 15 segments
Heat pumps get talked about like they're brand new technology — they're not. On this episode of the Energy Unwrapped Podcast, I sit down with Nathan Gambling, lecturer in plumbing and heating and host…
But Nathan and I were so keen to get the episode recorded that in the end we just gave up fighting with it and ended up using Zoom instead.
So the audio should be fine, but the video isn't quite as good as I'd normally like.
Hopefully you can forgive us because it turned into a really interesting conversation.
We've got Graham Haldane experimenting with heat pumps in the 1920s, John Sumner taking heat from the River Wensum in Norwich in the 40s, and Nathan's own family working across combustion, oil heating, refrigeration, and some very early commercial heat pump systems.
And it wouldn't be a conversation with Nathan without us both going off on a few rants.
