Calculate the heat loss of your shop. Every thing you calculate must be based to give enough heat to overcome this. The tubing size, number of loops, loop layout and boiler sizing are all based off your heat loss.

I also for got to mension I live in northern Ontario where winters get to -40 and we fix vehicals so there are frozen vehicals in the winter months coming in for repair.

How well insulated is the shop?

Are you going to do the install?

I think he is referring to a overhead gas infrared system and not floor heat.

be sure to make sure you get full coverage of the floor as well. There is more to tube heaters than just matching up the output to the heat loss, ideally you want the configuration to "paint" the entire building in heat, not just throw lots of heat at a certain area.

I am 6 months in with my tube heater and I am very glad I went this route over forced air, there is no comparison.

the walls are r 21 and the ceiling is r40 metal lined, this is a automotive shop, I was wondering if I need 1 40-50 ft heater or 2 of them one at the front of the shop and one bellow the doors . will radiant tube heaters heat 40ft away from the front wall on a 45 deg angle.

My 50' center-dual fire at 45 deg heats fine across that distance.
