Did I miss this in my training?

I thought Pitot Heat was only needed in icing conditions. Tom Haines column
in this months AOPA mag recommends turning it on in or near moisture at any
temperature. Is this a typical recommendation?



I asked my flight instructor that today and he said that if you can't
see visible moisture, you don't need pitot heat. I guess I can go along
with that for low-performance aircraft but something tells me there's
more to it. (I did read the Haines column, so maybe that's what got me
thinking.)

What's the life expectancy of a pitot tube heater?
