I'm wary of that, too, I don't think it's a good idea to introduce too much heat. If the optics get warm then you could get all sorts of other issues like tube currents, mirrors going out of shape etc. All you need is to keep the surfaces above the dew point.
Not having a temperature sensor or intelligent dew controller I try to manually adjust the heaters to be cold enough not to feel warm and just warm enough to prevent dewing.
