Boyertown REL-750-RF Oil-Fired Furnace 119K BTU 85%

The Boyertown REL‑750‑RF is a rugged 119,000 BTU, 85% AFUE residential oil-fired furnace engineered for high‑demand heating applications where a lowboy footprint and rear‑flue configuration are required. This oil-fired furnace's compact, low‑profile cabinet fits easily into basements and mechanical rooms with limited height, while the rear‑flue layout provides flexible venting options for retrofit installations. Built with Boyertown’s heavy‑gauge steel heat exchanger, the REL‑750‑RF delivers consistent heat transfer, strong durability, and stable performance under high static pressure.

A high‑capacity PSC blower produces 1,399 CFM, supporting up to 4 tons of airflow for homes requiring strong air movement or add‑on cooling. The insulated cabinet reduces operating noise and improves thermal efficiency, while the front‑access design simplifies installation and routine service. With its combination of high BTU output, dependable airflow, and a compact lowboy design, the REL‑750‑RF offers a long‑lasting, practical heating solution for homeowners who need strong performance in a space‑restricted installation.
