How a High-Efficiency Gas Furnace Works | Colliers WV

Quick Answer

A high-efficiency gas furnace reuses heat from exhaust gases before they exit the home. By condensing vapor into water, it converts nearly all its fuel into warmth—keeping Colliers homes comfortable, quiet, and efficient through the long Ohio Valley heating season.

Colliers’ hillside properties, older homes near Veterans Street, and damp Ohio River air make efficient heating critical. Many homes still run mid-efficiency 70–80% AFUE furnaces that lose heat through metal chimneys. New condensing models use dual heat exchangers and sealed PVC venting to reclaim that energy—ideal for the area’s terrain and moisture-heavy winters.

How Condensing Furnaces Work

Natural gas burns in a sealed combustion chamber, heating a primary heat exchanger that transfers energy to indoor air. Exhaust gases then move through a secondary heat exchanger, where leftover heat is extracted. As the vapor cools, it forms condensate that drains through PVC tubing. The cooled exhaust vents safely outside through small PVC pipes—simple, efficient, and perfect for older Colliers basements.

Components That Boost Efficiency

A variable-speed blower distributes air evenly in homes across Penco Road and Eldersville Road. The induced draft motor manages airflow for complete combustion, while electronic ignition replaces wasteful pilot flames. Sealed PVC venting draws outdoor air for burning, improving safety and indoor air quality. These parts work together to push efficiency toward 99% AFUE.

Why It Fits Colliers’ Homes

Colliers’ cold winters and hillside moisture challenge older heating systems. Condensing furnaces adapt automatically, running longer at lower speeds for steady comfort and minimal noise. Their sealed design prevents corrosion and drafts—an advantage for homes near valley slopes and wooded areas.

FAQs

Why is my furnace making water?

That’s condensate—normal water from cooled exhaust gases. It drains safely and indicates high efficiency.

Can I still use my chimney?

No. The exhaust is too cool for metal flues; sealed PVC venting is required.

Do Colliers furnaces need special maintenance?

Just annual cleaning of heat exchangers and the drain line keeps the system safe and efficient.
