Bosch EHK-20J Electric Heat Kit 20 Kw 2-stage 240V

Product Description

The BOSCH EHK-20J is a 20 kW electric heat kit designed for use with the 19 SEER Inverter Ducted Packaged Heat Pump. It operates at 240 VAC with a minimum circuit ampacity (MCA) of 105 amps, or 91 amps at 208 VAC. The kit provides 2-stage electric resistance heat, giving the system the ability to modulate heating output to match load conditions. This component is installed by licensed HVAC technicians as part of a packaged rooftop or ground-mounted heat pump system, adding supplemental or emergency electric heat capacity.

This heat kit is intended for residential or light commercial applications where supplemental electric heat is required within a packaged heat pump unit. It is engineered specifically for the 19 SEER Inverter Ducted Packaged Heat Pump platform. The 2-stage configuration allows the system control board to sequence heating elements, which supports more efficient operation and reduces demand spikes compared to a single-stage arrangement. Contractors integrating this kit should verify that the existing electrical service and disconnect are rated for the MCA requirements at the supply voltage being used.

Key Features

• 20 kW electric heat output for robust supplemental or emergency heating capacity
• 2-stage operation allows sequenced element activation for better load management
• 105 A MCA at 240 VAC and 91 A MCA at 208 VAC for dual-voltage flexibility
• Designed specifically for the 19 SEER Inverter Ducted Packaged Heat Pump
• OEM component ensuring fit and function within the BOSCH packaged system platform

Compatibility

Designed for use with the BOSCH 19 SEER Inverter Ducted Packaged Heat Pump. Confirm system model and electrical service ratings before installation.

Installation Notes

Installation must be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the packaged unit before servicing or installing the heat kit. Verify that the branch circuit, disconnect, and wiring are appropriately sized for the MCA at the supply voltage present on site, per NEC requirements. Do not energize the heat kit until it is fully secured and all wiring connections are confirmed.
