Heat strips, also known as electric resistance heat, are a common method used for heating indoor spaces. These strips consist of tightly wound coils of wire, typically made of alloys like nichrome. When you turn on the heat strips, an electric current flows through the coils, causing them to heat up. As electricity passes through the resistance of the wire, it produces heat energy, which is then transferred to the surrounding air. This warm air is then circulated throughout the room, effectively raising the temperature to a comfortable level. Heat strips offer a straightforward and efficient way to provide warmth indoors, making them a popular choice for heating systems in various settings.
Understanding the Basics of Heat Strips
Heat strips, also known as electric resistance heat strips or electric heating elements, are a common component in HVAC systems. They are used to provide supplemental heat during cold weather or when the primary heating source is insufficient. Heat strips work by converting electrical energy into heat energy, which is then transferred to the air that is circulated throughout the space.
When the thermostat detects that the temperature has dropped below the desired level, it sends a signal to the control board in the HVAC system. The control board activates the heat strips, and electricity begins to flow through them. As the electrical current passes through the resistance wire in the heat strips, it encounters resistance, causing the wire to heat up.
Heat strips are usually made of materials with high resistivity, such as nichrome or kanthal. These materials have a high melting point and can withstand the high temperatures generated when the electricity passes through them. The resistivity of the wire determines the amount of heat that is produced, so heat strips with different resistances can be used to vary the amount of heat output.
Once the heat strips are activated, a blower fan in the HVAC system pushes air over the heated coils. The air absorbs the heat from the strips and becomes warm. The warm air is then distributed throughout the space through ductwork or vents, providing a comfortable indoor environment.

The Role of Heat Strips in HVAC Systems
3. How Heat Strips Work
Heat strips are an essential component of HVAC systems that provide supplemental heat when the primary heating source is insufficient. These strips, also known as electric resistance heaters, work by converting electrical energy into heat energy.
When the heating system is activated, electricity flows through the heating elements of the strips, which are usually made of coiled conductive material. As the current passes through these elements, they resistance to the flow of electricity, causing them to heat up.
These heated elements transfer the heat energy to the surrounding air, which is then distributed throughout the space via the system’s blower. The warm air helps to maintain a comfortable temperature in the room, especially during colder seasons or when the primary heating system is not providing enough warmth.
Heat strips are typically installed inside the air handler of the HVAC system, either as part of the original unit or as an add-on. They are designed to complement other heating methods, such as heat pumps, to ensure optimal comfort and temperature control.
Unlike other heating methods like gas or oil furnaces, heat strips do not produce any combustion byproducts, making them a cleaner and safer option. Furthermore, they are relatively easy to install and require minimal maintenance compared to other heating alternatives.
