Baseboard heaters use either convective or radiant heating to warm a room. Convective heating is the process of air movement that carries heat from the source to the object being heated, while radiant heating is the direct transfer of energy from one object to another without the need for air. Radiant heating is more efficient than convective heating, and because baseboard heaters are so close to the floor, they mainly use radiant heating to warm a room. This means that they don't use very much electricity at all and are a great option for people who want to save money on their energy bill.
