Why The L.B. White Journeyman 360 DF Is Worth The Investment

This isn't just a heater, it's built with the same indirect-fired heat exchanger technology and dual-fuel flexibility as the smaller Foreman 230 DF, scaled up to deliver 360,000 BTU per hour, giving contractors and facility managers significantly more heating capacity while retaining the ability to quickly switch between propane and natural gas.

The Journeyman 360 DF specifically addresses the needs of contractors and facility managers heating large construction sites, warehouses, or event spaces with access to propane or natural gas who need maximum indirect-fired BTU output at a competitive price without paying for remote telematics features.

Maximum Gas-Powered Output, Genuine Fuel Flexibility. Delivering 360,000 BTU per hour with the ability to quickly switch between LP and NG fuels, this heater provides significantly more capacity than the smaller Foreman 230 DF while keeping the same indirect-fired clean air benefits, all at a price point that reflects L.B. White's simplified, competitively priced Journeyman line.
