We shall focus our attention on electric radiant floor heating systems, as they are the most common. They use electric cables laid under tiles. Tiles are good heat conductors, can hold temperatures for long periods, and distribute heat evenly. However, concrete, stone, or hardwood options are great, too.
Through electromagnetic waves, radiation emits heat to the air. These waves carry thermal energy. When they hit your floor, they transfer that energy to the floor material in form of heat. The diffused heat then travels from the floor up, heating your entire shed evenly. The heat energy can be regulated with a thermostat attached to the wall within your shed.
Radiant floor heating systems are ideal for heating small spaces of up to 100 square feet. For safety, the heating system should be fully embedded in the floor.
Due to minimal airflow, radiant floor heating provides comfortable and uniform warming, even at low shed temperatures. For the DIY enthusiast, installing electric underfloor heating is a fun project for heating a shed.
