The press release was to announce the British Columbia utility company, Terasen’s, move to local customer service call centres , but we’re interested in a paragraph halfway down about “geo-exchange heating systems” – presumably TerasenĀ  means heating and cooling (which is actually a *more* efficient system than heating-only).
The article states:
“Terasen is also expanding its range of energy options to include choices such as solar, thermal and geo-exchange heating systems.”
