What is an Upflow Furnace?

An upflow furnace is a type of heating system that operates by drawing in cool air from the bottom and expelling warm air from the top, hence the term 'upflow.' This upward airflow facilitates the efficient distribution of heated air throughout the home.

How Does an Upflow Furnace Work?

An upflow furnace operates by blowing heated air upwards from the bottom of the unit, making it efficient and effective for residential heating.

Upflow furnaces function by pulling air through return ducts and filtering the air before it enters the furnace. This filtered air then passes over a hot heat exchanger, which warms the air before it is recirculated back into your living space via supply ducts to various rooms.

Choosing the Right Upflow Furnace

Selecting the right upflow furnace for your home involves considering several factors. From sizing and capacity to energy efficiency and cost, making an informed decision is crucial. Here’s what to consider:

  • Sizing and Capacity Requirements: Choosing the right size furnace is essential. An undersized furnace may struggle to heat your space, while an oversized furnace can waste energy. Learn more about calculating furnace size.
  • Energy Efficiency and Cost Considerations: Energy efficiency is a vital factor. Look for furnaces with high Annual Fuel Utilization Efficiency (AFUE) ratings, indicating efficient fuel-to-heat conversion. Higher AFUE ratings can help lower heating and cooling energy bills and help reduce your carbon footprint. Also, consider initial costs, installation charges, and potential long-term savings when evaluating options.

Frequently Asked Questions On Upflow Furnaces

The choice between a downflow vs upflow furnace depends on your home's layout and specific heating need. Upflow furnaces are typically installed in basements or lower levels, whereas downflow furnaces are commonly installed in attics or higher levels. Upflow furnaces tend to work best in homes in colder climates and multi-story homes where warm air can rise to upper floors. Downflow furnaces tend to work better in homes without basements, single-story homes, or those with slab foundations where heating from the top down is more efficient.

Consult with an HVAC professional to determine if an upflow furnace vs downflow is the best option based on your home’s design, climate, and heating requirements.

Yes, an upflow furnace typically has the return air intake at the bottom. In an upflow furnace configuration, cool air is drawn into the furnace from the bottom, the air passes through the heat exchanger where it is heated, and the heated air is then expelled from the top of the furnace and distributed through the ductwork to heat the home.

No, a dedicated upflow furnace cannot be installed horizontally. However, some furnaces are designed to be multi-positional, meaning they can be installed in upflow, downflow, or horizontal configurations. Consult a professional HVAC contractor to ensure proper installation.
