A7: The infrared-rays not only radiate on the surface but also penetrate into the inside. Like the sunshine, VAL6's radiant heat travels directly, unaffected by wind or rain, to the place you want. Also, it doesn't automatically rise to the ceiling. Q8: What is the feature of forced air heater(HOT GUN)? A8: The forced air heater discharges the heat of combustion by blower fan. Therefore, the discharged hot air is powerful and reaches far and wide. If you have any other questions, please contact us.
