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