Product Overview

Merit ML193E Series

Single-Stage Gas Furnace with Constant-Torque Motor Design for Even Temperatures and Constant Efficiency.

The Power Saver™ constant torque motor in the ML193E adjusts airspeed based on demand, which means that it operates more efficiently than a standard motor. 

  • Energy-Efficient Design - With an energy rating of 93% AFUE, you pay for perfectly heated air, not wasted energy.
  • Dual-fuel operation - When the ML193E is paired with a Lennox® heat pump, it creates a system that automatically switches between electricity and gas, keeping you warm and energy efficient.
  • Duralok Plus™ heat exchanger, built for Lennox’ high-efficiency (90%) condensing gas furnaces, that’s made of high-quality, patented ArmorTuf™ steel to ensure high reliability and efficiency.
