In this month's Homebuilding and Renovating (or similar titled glossy)
there's a Super E (?) airtight house built to canadian standards which
uses
ground source heat pump heating.

Yeah - but Canadian electricity is cheap. I'd look at mains gas driven heat
pumps as these are a lot cheaper to run, albeit more noisily.
