Lennox 12R61 Heat Kit
The Lennox 12R61 Heat Kit (Model ECB25-7.5P) is a field-installed electrical heating section engineered for HVAC technician installation in high-demand residential and light commercial environments. This 7.5kW electric heat kit operates on a 240V internal power supply and is specifically optimized for seamless integration with Lennox CBX25UH and CBX25UHV series air handlers. By utilizing high-grade nickel-chromium resistance elements, the 12R61 provides a reliable supplemental heat source, delivering approximately 25,600 BTUH of heating capacity.
Designed for streamlined furnace installation and retrofit applications, this kit includes a terminal block and a 24VAC transformer/relay assembly. The heavy-gauge steel construction and precisely spaced heating coils ensure maximum airflow efficiency with minimal static pressure drop. Whether you are performing a Lennox air handler service or upgrading an existing unit to emergency heat status, the 12R61 offers the thermal density required to meet energy-efficient HVAC standards across diverse climate zones.
Key Benefits
- Compatible with Lennox 12R61 and ECB25-7.5P specifications for exact OEM fitment in CBX25UH air handlers.
- Features a 7.5kW 240V heating element, ideal for 1.5 to 5-ton nominal air handler sizes.
- Equipped with a terminal block for clean electrical terminations and reliable high-voltage connections.
- Compact design allows for easy insertion into the blower section without interfering with existing internal components.
- Includes a 24V control transformer, factory-wired for 240V but adaptable for 208V field applications.
Common Questions
- What is the heating output of the 12R61 kit? This kit provides 7.5 kW of heat, which translates to a nominal output of 25,600 BTUH at 240V operation.
- Is this kit compatible with other air handler brands? No, the 12R61 is engineered specifically for Lennox Merit Series air handlers, particularly the CBX25UH and CBX25UHV models.
- Does this include a circuit breaker? This specific catalog number (12R61/ECB25-7.5P) features a terminal block for connection to a remote disconnect or external breaker.
