Planning to get a XP 4 soon. I am considering the Polaris heater to allow us to use the general year round. For those that have one, if the blower is turned off, and the temp turned all the way down, do you notice heat coming from the vents? If so is it noticeable while riding or just at the vent? Do you use the blower to help circulate air, even when you aren’t using heat? I don’t need any extra help to sweat.
