Dayton 3VU31 Heater Overview

The Dayton 3VU31 is a portable electric heater designed for commercial and industrial heating applications. It uses a fan-forced milk-house style to deliver warm air across workspaces. The unit operates on standard 120V AC power with a NEMA 5-15P plug for immediate use.

Power Settings and Coverage Limits

Three heat settings provide output levels of 0.6 kW, 0.9 kW, and 1.5 kW, drawing 5 A, 7 A, and 12.5 A respectively. The fan moves 45 cfm of air with a temperature rise of 140 degrees F. This airflow volume suits spot heating rather than whole-room climate control.

Setup and Safety Considerations

The heater stands on a built-in base with a 72-inch cord for flexible placement indoors or outdoors. A manual-reset thermal overheat protection cuts power if internal temperatures exceed safe limits. Users must allow the unit to cool before pressing the reset button to restore operation.

Questions about this item

Which of the three wattage settings (.6 kW, .9 kW, 1.5 kW) should I choose?

Use .6 kW (5 A) for light background heat, .9 kW (7 A) for moderate comfort, or 1.5 kW (12.5 A) for maximum output on a dedicated 15 A circuit.

What does the 140 °F air temperature rise mean once the heater is running?

It means the discharge air is 140 °F hotter than the intake air, so the unit delivers a strong, fan-forced heat stream.

What does the NEMA 5-15P plug cap in practice?

The 5-15P plug limits the heater to a standard 120 V, 15 A household receptacle, capping the highest setting at 1.5 kW.
