I think HRV's are required by code now aren't they tgunn? I may be mistaken. We just moved into our new house in April, with an HRV, and yeah, it makes a HUGE difference.
Scott, I don't think they are in the same building, but they are the same guys. Shipping a 230g from Edmonton to our door was only around $200 (weight based I assume, this tank has 1/2" sides and a 3/4" bottom, so she's on the heavy side!). And yes, we have met, many times, LOL.
