“””heater batteries”” in construction typically refer to devices used in heating, ventilation, and air conditioning (HVAC) systems. They are also known as “”electric heater coils”” or “”heating elements.”” These heater batteries are often used in air handling units (AHUs) and are responsible for heating the air that is circulated throughout a building.
How they operate:
Heater batteries in construction generally work by passing an electric current through a resistive heating element. This heating element is usually made of materials such as nichrome or stainless steel, which have high electrical resistance. When the current passes through the element, it encounters resistance, and this resistance causes the element to heat up.
Air from the HVAC system is forced over or through the heated coils, and the air absorbs the heat from the heating element. As a result, the air temperature increases before being distributed to different areas of the building through the ductwork.
Heater batteries can have controls to regulate the heating output, allowing for temperature adjustments based on the requirements of the building’s occupants. They are commonly used in colder climates or during the winter months to provide warmth and maintain a comfortable indoor environment.”
