In conclusion, a variable speed furnace’s consistent run is a feature cleverly engineered to ensure efficiency and comfort, smoothing out temperature fluctuations and enhancing overall air quality.
Key Operational Features of Variable Speed Furnaces Running Continuously
A variable speed furnace, as the name suggests, operates at varying fan speeds to control the temperature throughout your home. A key feature to understand is its heat modulation which maintains a constant temperature by running almost continuously at low power, rather than cycling on and off at maximum power like a traditional furnace. This ability to fine-tune heat output ensures energy efficiency and superior home comfort with less noise and fewer drafts.
Another noteworthy feature is the ECM motor (Electronically Commutated Motor) which allows the furnace to operate more quietly and efficiently. This intelligent motor constantly assesses your home’s heating requirements and adjusts its output to match the need. The ‘Smart Motor’ technology can save up to 40% of your electricity use compared to a conventional furnace.
For optimal usage, variable speed furnaces come with unique features:
- Zoning systems: This lets you heat specific parts of your house, keeping each room at the desired temperature. It’s especially useful in large houses where different rooms may have different heating needs.
- Humidity control: With their longer run times, variable speed furnaces can improve your home’s humidity control. Longer run times allow for better air filtration and cleaner indoor air.
- Variable-speed blowers: These automatically adjust to account for factors such as dirty filters or duct blockages. This keeps the airflow steady, reducing sudden temperature swings.
Let’s see an example of ECM motor weekly usage compared to a conventional furnace motor in kWh below:
| Type of Furnace Motor | Avg. Weekly Usage (kWh) |
|---|---|
| Conventional Furnace Motor | 70 kWh |
| ECM Motor (Variable Speed Furnace) | 42 kWh |
This table clearly depicts the energy efficiency gained using variable speed furnaces with ECM motor, thus further solidifying the benefits and operational superiority of this technology over conventional furnaces.
