Heating, Ventilation, and Air Conditioning Products Design Apollo Multifunctional Heater by Dmitry Ozhegov Apollo is an electric convector heater designed for heating homes and offices. A full-size 4D air outlet grille distributes warm air evenly across the room for faster and smoother heating. The Intake Pro chassis keeps the air inlets clear and gives the unit a floating appearance. A compact Hedgehog heating element reaches operating temperature quickly and works silently. Three control options are offered: mechanical, electronic and digital inverter, the last with a colour display and an open-window sensor. An optional Wi-Fi module allows remote control.
