A column heater is a type of portable electric heater that consists of tall, narrow columns or panels filled with a heating element. These heaters are designed to provide consistent and efficient heat distribution in indoor spaces.
Column heaters can be energy efficient, especially models equipped with features like thermostats, timers, and adjustable heat settings. However, their efficiency can vary depending on factors such as insulation, room size, and usage patterns. It's important to choose a model with energy-saving features and use it wisely to maximise efficiency.
