About the HKTSD15XA

Where the HKTSD15XA fits

An electric heat kit is the resistance-heat element that slides into an air handler to provide backup heat for a heat pump, emergency heat, or primary heat in a straight-cool system. The HKTSD15XA is rated in kilowatts; the right size depends on the home’s heat loss, the climate, the heat pump’s capacity at low outdoor temperatures and the electrical service available. Kits are sold separately from the air handler and must be a model the air handler is listed to accept.

Heat kits are staged in some air handlers so only part of the element energizes on a mild day, which keeps electric bills down; a thermostat with auxiliary and emergency heat terminals lets the system use the kit only when the heat pump cannot keep up. Oversizing the kit raises the electrical service requirement without adding comfort.

What to check before you order

• Air handler compatibility: the kit must be listed for your air handler model and cabinet size.
• Kilowatt rating against the home’s heating load and the heat pump’s balance point.
• Breaker size and wire gauge from the kit data plate — larger kits need two circuits.
• Built-in circuit breaker versus terminal-block versions, as required by local code.

Installation and service notes

Power off at the panel, slide the kit into the air handler’s heater slot, land the field wiring on the kit’s lugs or breakers at the torque the label specifies, and set the air handler’s dip switches or jumper for the installed kilowatts. Confirm the blower runs on any heat call before closing up; a heat kit without airflow trips its limits or worse.
