L.B. White Volt 6 Electric Greenhouse Heater (240V)

L.B. White Volt 6 Electric Greenhouse Heater (240V)

The L.B. White Volt 6 is a 240V electric greenhouse heater that draws 25 amps and is designed to run flawlessly off a standard clothing dryer outlet — making it one of the most accessible high-output greenhouse heaters available. At $866, it's built for large greenhouse spaces where the Volt 3 isn't enough, delivering serious heat output with the same industrial-grade reliability as the rest of the L.B. White Volt lineup.

⚠️ Important: This heater requires a 220V/240V electrical connection. Ensure your receptacle is a NEMA 14-30P or NEMA 14-50P for plug compatibility. Special wiring may be required if you don't already have a 240V outlet near your greenhouse.

What Are the Key Specs of the L.B. White Volt 6?

• Voltage: 240V (220V compatible)
• Amperage: 25 amps
• Plug type: NEMA 14-30P or NEMA 14-50P
• Outlet compatibility: Standard clothing dryer outlet
• Overheat protection: Auto shut-off at 104°F
• Certifications: UL approved
• Operation: Combustion-free, no fumes or odors

Can the Volt 6 Run Off a Standard Dryer Outlet?

Yes — this is one of the Volt 6's most practical advantages. It uses a NEMA 14-30P or NEMA 14-50P plug, which is the same outlet type used by standard household clothes dryers. If you already have a dryer outlet in or near your greenhouse space, you can plug the Volt 6 in directly without any additional electrical work. This makes it significantly easier to install than heaters requiring custom wiring or dedicated circuits.

How Does the Volt 6 Compare to the Volt 3?

The Volt 3 draws 12.5 amps on a NEMA 6-15P plug and is suited for smaller greenhouse spaces. The Volt 6 draws 25 amps — double the amperage — and is designed for larger greenhouse areas where the Volt 3 can't maintain adequate temperatures. The Volt 6 also benefits from dryer outlet compatibility (NEMA 14-30P/14-50P), which many homeowners already have, whereas the Volt 3's NEMA 6-15P plug is more common in commercial settings. If you have a larger greenhouse or experience very cold winters, the Volt 6 is the stronger choice.

Is the Volt 6 Safe for Continuous Greenhouse Use?

Yes — the Volt 6 is engineered for non-stop, continuous operation. Safety features include automatic overheat protection that triggers at 104°F, a high-quality sealed motor, and powder-coated steel housing built to withstand the humid conditions typical of greenhouse environments. It operates without combustion — no fuel spills, no carbon monoxide risk, and no odors — making it a clean and safe choice for enclosed growing spaces.
