How heat pumps can turn wasted energy into low-carbon whisky

A century-old Scottish distillery has halved its CO 2 emissions with waste-heat recovery tech. Others could follow suit — if regulations and economics align.

    It’s actually a really cool concept honestly. I do this on a very tiny scale at home. I run a small server cluster largely as a playground but also for things like Plex and Vaultwarden. The waste heat from that is pushed out the back of the rack and a heat pump water heater a few feet away uses that to help heat water.

    As you said, seems like there are many opportunities to do this on a much lager scale.

      Nice, I have much the same setup in my house!

      I visited the recently Passive House certified student residence buildings at the University of Victoria, and the heat recovery there is quite interesting. Passive House requires a very low heating load, so they recover all the heat they can from the commercial kitchen (the presence of which is rare in a Passive House because of high ventilation requirements) processes such as ventilation hoods and refrigeration systems and put it into the DHW system.

      They had to get a bit creative with the design, but it’s really not that complicated. More just not doing things the way they’ve always been done.
