An upflow furnace pulls in air from the bottom and releases it out the top, while a downflow furnace does the opposite. Upflow furnaces are typically more efficient and provide better air circulation in homes with basements, while downflow furnaces are better suited for homes without basements. The differences in airflow direction impact heating efficiency by affecting how air is distributed throughout the home.
Downflow furnaces are typically more efficient than upflow furnaces because they utilize gravity to push warm air downward, which can result in better heat distribution. Upflow furnaces, on the other hand, may require more energy to push air upward, potentially impacting their efficiency. In terms of performance, downflow furnaces are often preferred for basement installations, while upflow furnaces are commonly used in attics or crawl spaces.

lower profile so more practical compared to downflow
I'm assuming that by "down draft furnace" you mean a counterflow or downflow furnace. This furnace takes its "cold air return" at the top, and blows the warm air out the bottom (typically, into ductwork that runs under the floor).Older downflow furnaces were dedicated to that configuration, and could not be mounted in other positions.Nowadays, most furnace manufacturers make "multi-poise" furnaces. They can be mounted in downflow, upflow, or side-flow positions, when they are installed according to the manufacturer's certified instructions.The HVAC Veteran
Not always true. There are upflow units, downflow units and horizontal side discharge units.
It is called an upflow furnace. This type of furnace takes in air at the bottom, heats it, and then releases it through the top vents.
PRESSURE INCREASES are normally effected by raising the height of water supply to increase the downflow. If this is not possible, increase the bore of the supply pipe from your tank.
Downflow fixed bed carbon contactors are vessels filled with activated carbon particles used for the removal of organic contaminants from water or air. Contaminated water or air is passed downward through the bed of carbon, allowing the carbon to adsorb the pollutants. This method is effective in treating drinking water, industrial wastewater, and exhaust air streams. Periodic replacement or regeneration of the carbon is required to maintain treatment efficiency.
Run/Ski/Climb to the edge. Otherwise find the lee (the downflow) side of a house or large object. Anything else and ull just get caught. Imagine snow lumps the size of a beach ball hitting you at 100 mph and higher....
C30A is the series of the evap coil. The nominal BTU rating (cooling) for this coil would be 48,000 BTUH (signified by the -047). The "U" indicates upflow, although it can be used in downflow orientation, as well. The "B" would be the case size - 17 1/2" wide.
According to SOWPODS (the combination of Scrabble dictionaries used around the world) there are 5 words with the pattern D--N-L--. That is, eight letter words with 1st letter D and 4th letter N and 6th letter L. In alphabetical order, they are: downflow downplay dronklap dwindled dwindles
In a downflow Rudd furnace, the air filter is typically located at the bottom of the unit, just before the blower. The filter is designed to capture dust and debris before the air is drawn into the heating system. Proper placement ensures efficient airflow and helps maintain indoor air quality. Always refer to the manufacturer's manual for specific installation and maintenance instructions.
