When you stand up, your face feels hot, feet are cold.
- t-writescode 6y agoRight. So are you meaning more than a vent but also cooling, then? Because it’ll just be hot air up there instead.
- fizixer 6y agoBy vent I meant both in and out (but one vent only doing one thing at a time). On more thought, I guess making hot air exit from top is always easier. So no need to switch: air comes in from the bottom vent (hot in winter, cool in summer) and out from the top?
- fizixer 6y agoOn further thought, two high vents, two low vents. Winter: lower vents on (one inlet, one outlet). upper closed. Summer: upper vents on (one inlet, one outlet). lower closed. The vents should be far apart to ensure cirulation (definitely not next to each other).
