Heat rises. The best spot to place a heater on is the floor. You can use a space heater to heat your office. It is best to place it on the ground or under your desk. You will be warmed by the heat slowly rising. To maximize efficiency, a ceiling fan should be run in the clockwise direction during winter to push warm, rising air down.What Type Of Space Heater Is The Most Energy-efficient?

Personal heaters of 200-400 watts are the space heaters with the lowest electricity consumption, however they do not provide enough warmth to heat family rooms.What's The Difference Between Forced Air And An Infrared Space Heater?
The most popular type of heater available is the forced-air heater. The heater heats the air, and includes a fan that blows warm air around the room to distribute the heat evenly. These heaters heat up the space but dry it out, which can lead to static buildup and skin dryness.Infrared heaters transfer radiant heat from the air to warm objects, instead of heating it.
