How Heat Strips Work On A Heat Pump

Heat strips, also called electric resistance heating elements or supplemental heat, are designed to provide additional warmth when an air-source heat pump cannot meet the heating load alone. They turn electrical energy into heat using resistive elements installed in the indoor air handler or ductwork.

Most systems use multiple-stage heat strips that engage progressively as the thermostat calls for more heat. Heat strips are simple, reliable, and responsive, but they are significantly less efficient than the heat pump’s compressor because they convert electricity to heat at roughly 100% efficiency versus a heat pump’s coefficient of performance (COP) that can exceed 200% to 400% in favorable conditions.

Types Of Heat Strips And Their Cost Implications

Understanding the types helps estimate replacement and upgrade costs.

Single-Stage Resistance Elements

These are basic electric coils that turn on at once. They are the least complex and typically the least expensive to replace. Costs for a single-stage element are often in the $100–$300 range for parts.

Multi-Stage Or Zoned Heat Strips

Multi-stage strips allow the system to add heat in steps (e.g., 5kW, 10kW, 15kW), improving comfort and reducing unnecessary power draw. They are pricier and sometimes require additional control wiring or a compatible thermostat. Part costs typically range from $200–$700.

Integrated Air Handler Elements

Some manufacturers sell heat strips as part of a full air handler or coil assembly. Replacing the entire assembly can be the most expensive option but may be necessary if the unit has additional damage or compatibility issues. These assemblies commonly run $800–$2,500 installed.

Typical Cost Ranges For Parts And Installation

Costs vary by location, unit size, and whether the work is DIY or professionally installed. The following ranges reflect typical U.S. market conditions.

Component	Low	High
Replacement Heating Element	$100	$600
Heat Strip Assembly	$200	$1,200
Control Components (relays, contactors)	$50	$300
Thermostat Upgrade	$80	$300
Professional Labor	$150	$800
Total Installed	$300	$2,000+

Factors That Affect Heat Strip Cost

Several variables determine final price. Evaluating these helps homeowners budget and choose the right solution.

System Size And Kilowatt Rating

Heat strips are rated in kilowatts (kW). Higher kW ratings produce more heat but cost more upfront and require heavier electrical service. A 5 kW strip will cost less than a 15 kW assembly.

Compatibility And Manufacturer

OEM (original equipment manufacturer) parts for specific heat pump models typically cost more than aftermarket universal elements. OEM parts provide guaranteed compatibility and often preserve warranties.

Electrical Service And Panel Capacity

Older homes may require panel upgrades to handle large heat strips. Upgrading service (e.g., to 200 amps) or adding dedicated breakers increases cost significantly and can exceed the cost of the heat strip itself.

Labor Complexity And Access

Installation in tight spaces, duct modifications, or multi-zone systems increases labor time and total cost. Weekend or emergency service may add premium charges.

Regional Labor Rates And Permits

Labor rates in urban areas and states with higher labor costs push installation prices upward. Local permit requirements or code upgrades can also add fees.

Operating Costs: What To Expect From Supplemental Heat

Operating cost depends on how often heat strips run and local electricity prices. Heat strips consume electricity directly, so they can be expensive compared to heat pump operation.

Example: A 10 kW strip running at full capacity uses 10 kW x 1 hour = 10 kWh. At $0.20 per kWh, that is $2.00 per hour. Continuous or frequent use during cold spells can quickly increase heating bills. Users should expect substantially higher operating costs when supplemental heat is used regularly.

Estimating Annual Cost

Calculate expected annual cost by estimating hours of operation per season, kW rating, and local electric rate. For example, 200 hours of use for a 7.5 kW strip at $0.18/kWh results in 7.5 x 200 x 0.18 = $270.

When Heat Strips Are Necessary

Heat strips are not required for all climates or heat pump systems. Their purpose is to protect comfort and provide backup heat under certain conditions.

• Extreme Cold: When outdoor temperature drops below the heat pump’s efficient operating range, strips provide necessary supplemental heat.
• Defrost Cycles: In cold, humid climates, defrost cycles temporarily reduce heat output; strips prevent indoor temperature drops.
• Rapid Recovery: When the system must recover quickly after door openings or large heat losses, strips can provide immediate heat.

Alternatives To Relying On Heat Strips

Improving overall efficiency and reducing dependence lowers both upfront and operating costs.

Cold-Climate Heat Pumps

Modern cold-climate heat pumps maintain higher COPs at low temperatures and reduce supplemental heat use. Upgrading to a cold-climate model may have higher upfront cost but lower long-term electrical consumption.

Insulation And Air Sealing

Improving home envelope performance reduces heating load and the need for supplemental heat. This low-tech solution often yields the best ROI.

Zoned Heating And Thermostats

Zoning with smart thermostats focuses heating where it’s needed, reducing hours where strips would otherwise run.

Secondary Heating Sources

Pellet stoves, gas furnaces, or mini-split systems can act as alternatives to electric strips where fuel costs are more favorable.

How To Minimize Heat Strip Costs

Cost reduction can target both installation and operation.

• Choose the Correctly Sized Strip: Oversized heat strips increase electrical upgrades and operating costs.
• Compare OEM Versus Aftermarket: Aftermarket parts can save money but verify compatibility.
• Shop Multiple Contractors: Get three bids and check references to avoid overpaying for labor.
• Improve Home Efficiency: Lowering heat loss reduces strip runtime and electricity costs.
• Consider Heat Pump Upgrade: In climates with frequent strip use, a modern cold-climate heat pump may pay off over time.

Installation Checklist And Questions For Contractors

Homeowners should ask targeted questions so quotes are comparable and meet local code.

1. What is the kW rating of the proposed heat strip and is it OEM compatible?
2. Will this require a service panel upgrade or permit? If so, who handles them?
3. Are thermostats or control board changes included?
4. What is the warranty on parts and labor?
5. Can the contractor provide references or pictures of similar installs?

Common Problems And Maintenance Considerations

Heat strips are durable but can fail or cause issues if not maintained properly.

Burnt Elements And Corrosion

Over time elements can fail, causing loss of supplemental heat. Regular inspection during annual HVAC service will catch early signs.

Control Failure

Relays, contactors, and thermostats control strip operation. Faulty controls can lead to strips staying on continuously or failing to activate.

Electrical Overloads

Incorrect wiring or insufficient breaker sizing can trip circuits or damage panels. Proper sizing and installation are critical for safety.

Frequently Asked Questions

How Long Do Heat Strips Last?

With normal use, heat strips often last 5–15 years. Lifespan depends on cycling frequency, environmental conditions, and electrical stress.

Can Heat Strips Be Repaired Or Must They Be Replaced?

Individual elements can sometimes be replaced, and controls repaired. In some older or damaged air handlers, replacing the entire assembly may be more practical.

Are Heat Strips Covered By Warranty?

Coverage depends on manufacturer and installer warranties. OEM parts may be covered under the equipment warranty, while aftermarket parts typically have separate warranties. Labor warranties vary by contractor.

Do Heat Strips Increase Fire Risk?

When installed correctly and maintained, heat strips are safe. Risks arise from improper wiring, blocked airflow, or failed controls. Regular HVAC inspections and professional installation mitigate these risks.

Practical Example Scenarios

The following examples illustrate cost outcomes in real-world scenarios.

Scenario A: Simple Element Replacement

Mid-sized home with a failed 7.5 kW strip. Part cost $250 plus labor $200. Total: $450. No electrical upgrade needed. Operating costs remain unchanged.

Scenario B: Full Assembly Replacement And Panel Upgrade

Older home requires a 12.5 kW assembly and panel upgrade to 200 amps. Parts $900, labor $600, electrical upgrade $1,500. Total: $3,000. Higher upfront cost but ensures safety and capacity for future upgrades.

Scenario C: Upgrade To Cold-Climate Heat Pump

Frequent cold spells cause heavy strip use. Replacing the entire heat pump with a cold-climate model costs $6,000–$12,000 installed. Energy savings and reduced strip use can offset cost over years depending on local electricity prices.

Key Takeaways For Homeowners Considering Heat Strip Costs

Heat strip costs range from a few hundred dollars for simple replacements to several thousand when electrical upgrades or assemblies are required. Operating costs can be significant during cold periods because electric resistance heating consumes a large amount of power. Evaluating alternatives like system upgrades, improved insulation, and zoning often leads to better long-term value.

Request detailed quotes, verify compatibility and warranty terms, and consider both installation and operating costs when deciding whether to repair, replace, or upgrade heat pump supplemental heating.
