It depends on the model
Most energy Star models will use an ECM motor which use some 20-50wh typical.
PSC motors use around 60-150Wh
Assuming a 24 run time and top Draw you're looking at 1.2KWh - 3.6KWh.
Using $0.13kwh on peak to keep it simple
You're looking at less than $0.16-0.47 a day to run.

Honestly if you're thinking an HRV will save you money in ontario it's a laugh. Not that an HRV won't save energy. It's just that the rate for hydro is so ridiculously high and NG is so low (relatively) that it ends up a wash.
But the advantage of a properly vented house is another story

Neligible amount.
I run my HRV 24/7, at 20min on and 40min off and my hydro usage was never excessive.
As an example for last month's hydro usage; it was 442.31kWh and my current home is 3500sqft.

Efficient. Especially with your mining rigs.
I've been in to the 500kWh these last couple months since we've been home more.

It will be higher this time around, now that the mining rig has been running steady 24/7 (had to disassemble and reassemble and tweaked a bit).
It helps that we are not home 10hrs a day Mon-Fri and by the time we do get home, most of our usage is off-peak.
