The HEAT CONTROLLER LLC 10W50 is a 15 kW electric heat kit designed for use with 2.5 to 5 ton air handler or heat pump systems. It provides supplemental or emergency electric resistance heating capacity integrated directly into the air handling unit. Licensed HVAC technicians install this kit as part of a split-system or packaged unit configuration to meet heating demand when the primary refrigeration circuit cannot carry the full load. At 15 kW, it delivers meaningful supplemental heat output suited to residential and light commercial applications.
This heat kit is sized for systems ranging from 2.5 to 5 tons, making it applicable across a range of residential and light commercial air handlers. It is typically field-installed into a compatible air handler cabinet to add electric resistance heat capacity. This type of kit is commonly used in heat pump applications where auxiliary or emergency heat is required during low outdoor ambient conditions or during defrost cycles.
Designed as an OEM-style electric heat kit replacement or add-on for 2.5 to 5 ton residential and light commercial air handlers and heat pump systems.
Installation should be performed by a licensed HVAC technician in accordance with local codes and NEC requirements for electric heating equipment. Disconnect and lock out all electrical power to the air handler before beginning installation. Verify that the existing electrical supply circuit is rated for the additional load before energizing the heat kit. Follow the air handler manufacturer guidelines for proper mounting and wiring connections within the cabinet.
