We've been here before. Checked the wiring and turned my electric
furnace on and got a modest "hummmmmmmmmmm" for my efforts.

No big deal, I guess, as I had money in the circuit breaker and cable,
but not in the furnace. Which is why I don't wish to add any more cash
to that cow.

I've been looking at the radiant heaters Lee Valley has: has anyone
here tried that radiant heat concept recently enough to recall whether
or not it works well?

If it seems to, I'll stick one of those up in each corner of the shop
and get on with it. I'm not up for rerouting ducting for a furnace,
among other fun chores, so ceiling mount radiant heat might be the
answer.
