Why The L.B. White Foreman 230 Oil Is Worth The Investment

This isn't just a heater, it's built with a fully self-contained onboard 33-gallon diesel tank and the same indirect-fired heat exchanger technology as the Foreman 230 DF, giving contractors and facility managers genuinely clean, dry heat without depending on a gas line or propane tank, plus the same LINK telematics for remote monitoring.

The Foreman 230 Oil specifically addresses the needs of contractors and facility managers working job sites without natural gas or propane access who still want indirect-fired clean air, extended ductable reach, and remote visibility into heater performance.

Self-Contained Diesel Power, Same Clean Indirect-Fired Heat. Running on a fully self-contained 33-gallon diesel tank providing 19 to 20 hours of runtime, this heater delivers the same indirect-fired clean air and 100-foot ductable reach as the gas-powered Foreman 230 DF, without needing a propane tank or gas line hookup on site.

Built For Serious, Monitored Heating Performance

Delivers 230,000 BTU/hr with industry-leading quiet operation at 70 dB or less

Indirect-fired technology keeps combustion completely separate from heated air, delivering genuinely clean, dry heat

The onboard 33-gallon fuel tank provides 19 to 20 hours of runtime before refueling

Engineered For Jobsite Durability And Remote Visibility

A centralized control panel with volt and hour meters streamlines setup and maintenance

Equipped to move manually or with a lifting bail for job site portability

Real Savings

A self-contained diesel tank eliminates the need for a gas line or propane tank on remote job sites

LINK telematics reduces the labor of manually checking on heaters across multiple job sites or locations

A 2-year warranty with lifetime technical support reduces the risk of unexpected repair costs

Free shipping and no sales tax through Summit Forge Supply keeps the total cost down compared to buying elsewhere and paying tax and freight separately

The Bottom Line Contractors and facility managers working job sites without gas access who still want genuinely clean, indirect-fired heat and remote monitoring can't get that combination from a gas-dependent heater. The L.B. White Foreman 230 Oil is built with a self-contained 33-gallon diesel tank, indirect-fired clean air, 100-foot ductable reach, and LINK remote monitoring, so it delivers premium heating performance wherever gas access isn't available.
