Frequently Asked Questions

• How do I choose the correct kW heat strip size for my Daikin air handler?

  Match kW to your system tonnage, climate, and electrical capacity. As a general guide, moderate climates often use about 2 kW per ton, colder zones may need more. Confirm with load calculations and the air handler’s approved heater list.

• What electrical breaker and wiring requirements are typical for each Daikin heat strip kW rating?

  Follow the kit nameplate MCA/MOCP and local code. Typical 240V single‑phase examples: 5kW ~30A breaker, 8kW ~40A, 10kW ~50A; 15-20kW often require dual circuits (e.g., two 50-60A). Larger 30-75kW kits may be multi‑circuit or 3‑phase.

• Are these Daikin heat strips compatible with my specific air handler model number?

  Yes, when the heater model is listed for your air handler series, cabinet size, and voltage. Check the product data/installation manual for approved electric heat kits and match exactly.

• Do I need a licensed electrician or HVAC contractor to install a Daikin heat kit?

  Yes. Professional installation is required to meet code, ensure safe wiring, verify airflow, and protect warranties.

• How does auxiliary electric heat interact with a Daikin heat pump’s operation and thermostat settings?

  The thermostat calls for auxiliary heat when space temperature lags or during defrost. Emergency heat bypasses the compressor and runs electric heat only. Use a thermostat that supports AUX/EM HEAT.

• What are the typical amperage draws for 5kW through 75kW Daikin heat strips?

  At 240V single‑phase: 5kW ≈ 21A, 8kW ≈ 33A, 10kW ≈ 42A, 15kW ≈ 63A, 20kW ≈ 83A. Large 30-75kW kits often split across multiple circuits or use 3‑phase; current varies by voltage. Always verify the nameplate.

• Can I upgrade or downgrade kW size without changing other components?

  Often yes, if your Daikin air handler is listed for that heater size and your electrical service supports it. You may need different breakers/wiring and compatible thermostat staging.

• What safety features (fuses, limits) are included with Daikin heat strips?

  Kits include high‑temperature limit controls and sequencers/relays; many models add internal fusing or disconnects. Airflow interlocks prevent operation without proper blower CFM.

• Do heat strips change SEER2, BTU/tonnage, or refrigerant compatibility?

  No. SEER2/HSPF2, BTU output, tonnage, and refrigerant type are set by the matched system. Electric heat kits are separate from the refrigerant circuit.

• Are light commercial sizes available and in stock?

  Yes. We stock a wide range up to 75kW for light commercial applications with fast turnaround. Confirm lead times at time of order.
