Baseboard Heater

A low-profile heating unit installed along baseboards that distributes heat through convection. Hydronic baseboard heaters circulate hot water from a boiler through finned copper tubing. Typical output ranges from 500 to 700 BTU (British Thermal Units) per linear foot depending on water temperature and airflow. Requires clear airflow for efficient heating.
