Heating solutions for a 90,000 sq ft shop

[drawyennik]

I'm looking for 2 things.

1. What is the best way to heat a 90,000 sq ft shop 60,000 is already built and in place 30,000 is going to be built?

2. What is a rough ball park cost?

Thanks,

Draw

Actually 3 things

3. A vendor in BC that would handle the design of a system like this

Gas-fired unit heaters are probably your cheapest/easiest option. Lowest comfort, but likely not an issue. You can get efficiencies up to condensing on some of the new unit heaters.

Probably looking at ~4 unit heaters, $2000 each installed, plus gas line.

As far as vendor design, I'd shell out the couple bucks and have a local consultant do up a plan.

many shops use radiant heaters. Personally, I think they are wasteful since they depend on high temperatures and hence have low efficiency (hot exhaust).

(but people also claim they deliver heat more efficiently, especially at high ceilings and much infiltration, that you would have with overhead doors in a shop)
