Wow, now that is something to be proud of.
Looking over the specs for their loop field, I'm surprised that they didn't space the holes further apart.
But interestingly, they did give their recipe for their grout: High solids grout – 9% Blast Furnace Cement, 9% Portland cement, 32% fine silica sand, 50% water.
I'm surprised that they didn't go for radiant floor heating... I've been watching a BBC series called Grand Designs, which follows interesting home builds from concept through completion, and although the series misses the opportunity to focus on energy issues, all of the builds use radiant floors, and every bathroom has a heated towel rack.
But all in all, this is the way of the future.
Maybe someday the US will catch up to Canada.
