A baseboard heater is a type of heating system installed along the base of walls in a room. It works by using either electricity or hot water to warm the air, which then rises and circulates throughout the space. This design helps to provide consistent and comfortable heat without taking up much room. Baseboard heaters can be found in many homes and are often used as a primary or supplemental heating source. They are typically controlled by a thermostat, allowing users to adjust the temperature to their preference. Common types include electric baseboard heaters and hydronic baseboard heaters.
