ICBW but I thought dessicant wheel types would.

You might be right.
However, these use more power (for the same level of dehumidifying),
and I suspect a heater of the same power rating would be just as
effective.

The heater I use in the shed is a 1kW oil-filled radiator, but with
a series diode to limit it to 500W. When the system is running, the
heating duty-cycle is so low that when you feel the radiator, you
would not even think it has been on. The power output required to
drop the RH from 100% to 80% at low temperatures simply by raising
the temperature is remarkably low.

I had not expected this initially and using a heater was going to be
a stop-gap before trying a dehumidifier, but when I found how little
heat was required, I dismissed using a dehumidifer in the shed.


Does that work across the whole shed with a single heater? I would have expected
the heat would not reach all necessary areas sufficiently.

I have a 1.5 width garage I would like to do something similar with, and was
wondering about a dehumidifier.,,
