I have dabled in radiant heaters, but they are not terribly efficient. But they can be used in a smaller area which is nice. A worm tube or drywall heater in my opinion is better since they are more directional.

I live in the LA area, and do commercial hvac. I see the stuff, but you live in the Great white north.

One option to consider is hydronic heating. You use a recirc pump off of a hot water heater through a coil with a blower motor. It is very efficient, but seriously drags in recovery time. Meaning if you turn it on when you need it. It is going to be a few hours before it is warm. Where as it is very effective to turn on, and just leave on. Especially in a shop. Set it at 50*, and let it roll. That way a sweater is comfortable to work in. Just use aqua pex to run the lines with decent sweeps when turning. Copper with 90's will pin hole in several years, and be annoying.
