Gas furnace

Quick Answer

A high-efficiency gas furnace reuses heat from exhaust gases before releasing them outdoors, turning up to 99% of fuel into warmth. In Wellsburg homes, this means steady comfort, lower utility bills, and quieter heating through long Ohio Valley winters.

Wellsburg’s riverfront humidity, older housing stock, and narrow basements along Main Street make efficient heating a priority. Many homes near Pleasant Avenue, 27th Street, and Bethany Pike still rely on mid-efficiency furnaces that vent heat up a metal flue. Modern condensing models recover that wasted energy using dual heat exchangers and sealed PVC venting—perfect for the area’s mixed home styles and damp climate.

How a Condensing Furnace Works

Inside the furnace, air and natural gas ignite in a sealed combustion chamber. The flame heats a primary heat exchanger, transferring warmth to indoor air. Then, instead of wasting exhaust heat, gases move through a secondary heat exchanger, where vapor cools and condenses into water. That condensate drains safely through PVC tubing, and the cooled exhaust vents outside through small PVC pipes instead of a chimney.

What Makes It So Efficient

A variable-speed blower provides even airflow in older two-story homes near Charles Street. The induced draft motor regulates airflow for safe combustion, while electronic ignition eliminates wasted fuel from pilot flames. Sealed PVC venting improves air quality by pulling outdoor air for burning. Together, these parts recover energy that older systems lose—boosting both comfort and efficiency.

Why It Fits Wellsburg’s Climate

Cold river air and long heating seasons can strain older systems. Condensing furnaces handle these conditions better, running longer at lower speeds to maintain even warmth and lower noise. Their cooler exhaust also helps prevent corrosion in Wellsburg’s damp winter air, protecting both the furnace and surrounding masonry.

FAQs

Why does my furnace make water?

That’s condensate—water from cooling exhaust gases. It drains safely and is normal.

Can I reuse my old metal vent?

No. High-efficiency furnaces require sealed PVC venting for safe exhaust.

Do Wellsburg furnaces need yearly service?

Yes. Annual cleaning keeps heat exchangers efficient and prevents drain buildup.
