Understanding Electric Heat Kits and Heat Strips

Electric heat kits, commonly known as heat strips, are essential components in many modern HVAC systems, particularly heat pumps. They serve as auxiliary or emergency heating elements when the primary heat pump cannot extract enough heat from the outside air during extreme cold. Operating much like a large toaster or hair dryer, these heavy-duty nichrome wire coils generate immediate, intense heat as electrical current passes through them.

For HVAC technicians and homeowners alike, selecting the right OEM electric heat kit ensures that the air handler safely and effectively distributes warm air throughout the ductwork. Proper installation prevents cold blows during defrost cycles and provides a reliable backup heating source.

Brand Compatibility	Match exact air handler model	MRCOOL Signature, VersaPro
Voltage	240V — verify panel amperage	10kW typically needs 60A breaker
Breaker Included?	Check if kit includes circuit breaker	Some require separate disconnect

Frequently Asked Questions

What size heat strip do I need for my HVAC system?

The size depends on your climate and home size. A 5kW to 10kW strip is usually sufficient for mild climates or smaller homes, while 15kW to 20kW kits are needed for larger homes in colder regions. Always perform a Manual J heat load calculation.

Can I install an electric heat kit myself?

Because heat kits involve high-voltage electricity (240V) and significant amperage, installation should be performed by a licensed HVAC technician or qualified electrician to ensure safety and code compliance.

Why does my heat strip smell like burning when I turn it on?

A burning smell is common the first time a heat strip is activated for the season. This is just dust burning off the nichrome coils and should dissipate within a few minutes.

Do electric heat kits work with heat pumps?

Yes, electric heat kits are designed to work seamlessly with heat pumps, providing supplemental heat during extreme cold or acting as emergency heat if the compressor fails.

How do I know if my heat strip is bad?

Signs of a bad heat strip include the system blowing cold air while in "Emergency Heat" mode, unusually high electric bills, or visible breaks and burns on the nichrome wire coils.
