dewcap in hi-res imaging

Would the use of a dewcap heater reduce the resolution of the telescope due to the warm air generated just on the telescope aperture?

See the images in this thread and this thread. To see what it looked like when the heater strip was on. I have a 12V 1.5A wall wart that I have hooked up to the strip...no heater control. I also have a separate dew shield that I also use.
