The Hydronic Electric Baseboard Heater is the perfect way to add warmth and comfort to any room in your home without spending a fortune. The permanent mount unit features heating elements that are immersed in a heat transferring liquid and enclosed by a copper casing with aluminum fins. To ensure safety, an automatic thermal linear limit is used throughout the entire heated length of the unit, and a complete wire guard extends along the entire outlet area of the baseboard. The powder coated, 12 ga. heavy duty extruded aluminum housing construction of the baseboard model also features junction boxes on each end of the unit to allow for easy access. This hydronic electric heater comes with brown finish, and is fully functional at high altitude settings.
