It’s always a challenge to heat construction sites, but for a company working in the remote and chilly oil sands area of Canada, the extreme conditions made it particularly challenging. 

The company had been using old diesel-fueled Frost Fighters but these had to be located outside the building and gave patchy heat, needed to refuel every six to seven hours, and often resulted in spillages which meant the need for yet another environmental report. Added to that, the eleven buildings were scattered across a large area and were of differing sizes so a one-size-fits-all approach wasn’t possible. Could we come up with a better heating strategy?
