L.B. White Volt 9 Electric Greenhouse Heater (240V)

L.B. White Volt 9 Electric Greenhouse Heater (240V)

The L.B. White Volt 9 is the newest and most powerful heater in the L.B. White Volt electric lineup. At $1,097, it operates on 240V, draws 37.5 amps, and uses a NEMA 14-50P plug — the same outlet type used by standard household clothes dryers — making it accessible without custom electrical work for most homeowners. It produces the highest heat output of any Volt heater and is designed to warm large greenhouse spaces where the Volt 6 isn't enough.

⚠️ Important: This heater requires a 220V/240V electrical connection with a NEMA 14-50P receptacle. 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 9?

• Voltage: 240V (220V compatible)
• Amperage: 37.5 amps
• Plug type: NEMA 14-50P
• Outlet compatibility: Standard clothes dryer outlet (50-amp receptacle)
• Overheat protection: Auto shut-off at 104°F
• Certifications: UL approved
• Operation: Combustion-free, no fumes or odors

How Does the Volt 9 Compare to the Rest of the Volt Lineup?

The L.B. White Volt lineup covers three power levels:

• Volt 1.5 — $390 — 120V, 1,500W, standard outlet, best for smaller greenhouses
• Volt 3 — $547 — 240V, 12.5A, NEMA 6-15P, mid-range output
• Volt 6 — $866 — 240V, 25A, NEMA 14-30P/14-50P, high output
• Volt 9 — $1,097 — 240V, 37.5A, NEMA 14-50P, highest output for large greenhouses

The Volt 9 is the right choice when the Volt 6 can't maintain adequate temperatures in your greenhouse — typically in very large structures, extremely cold climates, or greenhouses with significant heat loss.

Can the Volt 9 Run Off a Standard Dryer Outlet?

Yes — the Volt 9 uses a NEMA 14-50P plug, which is the same 50-amp outlet type used by many household clothes dryers and EV chargers. If you already have a NEMA 14-50P receptacle near your greenhouse, you can plug the Volt 9 in directly. Note that the Volt 9 draws 37.5 amps, so verify your circuit can handle that load before connecting.

Is the Volt 9 Safe for Continuous Greenhouse Use?

Yes — the Volt 9 is engineered for non-stop, continuous operation. Safety features include automatic overheat protection 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.
