Fully insulated cabinet

The fully insulated cabinet on this unit features a solid steel design with a secure fit door latch system. Not only does this help keep the heat moving through your ductwork, but the insulation cabinet works alongside the soft-mounted blower motor and inducer motor to help keep the noise down even further.

Air purifier and humidifier compatible thermostat

The thermostat on this unit is designed to be compatible with various other systems, such as an air purifier or humidifier. An air purifier can be beneficial in your home because it helps clean the air, removing unwanted allergens and unpleasant airborne particles from your air. A humidifier system is also useful in preventing the air from becoming too dry in your home during the coldest winter days, which can cause discomforts such as dry skin and dry eyes. The thermostat in this unit also includes additional technology that can keep track of the humidity levels inside your home.

RPJ (Rigid Press Joint) primary heat exchanger

The RPJ heat exchanger, built with durable and corrosion-resistant stainless steel, helps improve heat transfer and efficiency by moving more heat to the outside surface as opposed to a standard heat exchanger.

Model comparison by features – Tempstar F9MXE versus Tempstar F9MVE

Although the F9MXE and F9MVE have similar efficiency ratings of around 96%, the F9MVE lives up to its place in the “Deluxe Series” by offering extra features. For example, the F9MVE comes with the impressive Observer communicating wall control. This wall control can control up to six separate heating zones in your home, and the Smart Recovery feature adjusts your pre-set zones to your customized comfort levels.

Model Comparison by premium tier – Tempstar F9MXE versus F9MAE

The top offering by Tempstar, the F9MAE features a modulating operation and a host of other impressive features. The F9MAE beats the single-stage operation of the F9MXE by utilizing a modulating operation, which means that the F9MAE can increase or decrease heat in small increments, ensuring your home always stays at the temperature indicated on the thermostat. This is compared to the F9MXE, which utilizes a single-stage operation. This means that when the temperature in your home drops low enough the furnace will kick in on high fire mode causing temperature swings that are eliminated by a modulating operation. Also, the F9MAE features the intuitive ION System Control which can be accessed remotely by a compatible WIFI enabled device, meaning you can control your furnace settings wherever you are!
