Turn your heat vent into an intake vent for your furnace.

Turn your heat vent into an intake vent for your furnace.

I have 2 heat vents close to my stove located on the first floor. I identified those vents and made them the intake vent on the furnace. I made a box that snuggly fits under the furnace fan. I boarded up and insulated all around the fan. Now air is sucked out away from the hottest part of my house where the stove is and delivered to the upper floor via preexisting duct. This keeps my first floor cooler and more comfortable and my second floor warmer and more comfortable. Presently 73 first floor 71 second floor. Everything around the fan has been blocked off and insulated. My fan is turned on and only blowing air from the stove area to the upper floor.

This duct became my intake & was mounted directly below the fan.

These 2 heat vents were connected to the same 10" duct.

Is the fan constantly running or thermostatically controlled?

I have the fan set to run constantly on low. The blower motor is a GE ECM 2.3. Below is some cut & paste info regarding the high efficiency low operation cost for this motor. The motor is supposed to be amazing.

Equipment manufacturers don’t condone poor duct design, but ECM 2.3 motor technology can compensate for some applications if sized incorrectly. However, it is important to be cautious, because increased noise levels, which are uncharacteristic of these motors, may result if the design is overly restrictive.

Overall, ECM 2.3 motors draw the least amount of watts, which makes them the most efficient. On average, they will use approximately 413 watts in cooling mode and only 83 watts (less than a 100-watt light bulb) in continuous fan mode. This combination of performance, reliability, and programmable flexibility makes ECM 2.3 motors an ideal solution for high-SEER or multi-stage system designs. It also has the potential to increase overall cooling system performance by as much as one or more SEER points.

Beyond programmability and efficiency, ECM 2.3 motors offer many other advantages that enhance consumer comfort. These motors are the quietest of the three motor types because they have the ability to ramp up and down slowly, making them ideal for applications where noise is a concern.

Variable-speed motors are also the best choice for constant fan or constant filtering applications because the motor will only run at about one-third of its designed speed, using less power than a 100-watt light bulb and resulting in both noise reduction and energy savings that the consumer will appreciate. The indoor environment will also benefit from better air stratification, ensuring more consistent and precise temperatures.

In addition, ECM 2.3 motors have the ability to deliver customized airflow based on the consumer’s geographic region, making them versatile in humid, arid, or temperate climates. If dehumidification is required, variable-speed motors offer the best solution because of the wide range of speeds, and they are particularly effective when combined with two-stage compressors and a dehumidification control.
