Title: Isn't Leeds Pipes an old concept dressed up as a new story?
Post by: chris on 14/08/2018 11:05:53: The city of Leeds is setting up a heat distribution system that will send waste heat - via hot water - from an incinerator plant to local homes. This is being billed as a big step forward and an advance in cleaner, greener, more sustainable living.

But I remember my Dad doing an Open University course in the early 1990s on combined heat and power infrastructure, and a woman studying with me in Cambridge in the mid 90s was from Moscow where she said this sort of shared heat infrastructure was the norm - and great until it broke down...

West Dean College nr Chichester uses waste wood to heat the campus.

(They also supply 3-phase power to most houses, making high load distribution for cookers and washing machines more efficient if somewhat difficult for other European manufacturers to compete).

I think one of the earliest Combined Heat and Power installations was in London where a power station (Battersea? Lots Road) on the south side of the Thames supplied heat to a block of luxury flats (Dolphin Square?) on the north side from the 1930s to the 1960s.

I think wind power might be older than that.

Why's that? What are the advantages?
