Heating the tube to keep dew of a Newtonian mirror

Just wondering what experienced people thought of the idea of heating the tube via a heating wire moulded around the inside of the tube say 100mm above the mirror and then the heat just warms the tube slightly and the fans can then create a vortex in the tube to help reduce condensation..?

Anyone used this method? Pro's, con's?

Mike
