Plug-in freeze protection outlet
The HEATIT ET-21 is a plug-in thermostat outlet designed to protect pipes, engines and other equipment from freezing. It suits homeowners, contractors and vehicle owners who need automatic cold-weather power control without wiring.
1800 W heating capacity with fixed set-points
The outlet energises connected loads when the ambient temperature falls to 38 °F (3 °C) and cuts power again at approximately 50 °F (10 °C). It handles resistive heating loads up to 1800 W at 120 VAC, drawing a maximum of 15 A, so it runs most portable heaters and heat-tapes within that limit.
120 VAC CSA-approved for dry locations only
The device is certified by CSA for 120 VAC use in dry indoor or sheltered outdoor locations. It provides no cooling function, no adjustable temperature range and no digital programming. It cannot switch refrigeration loads above 720 W and must not be used in wet or damp environments.

Questions about this item
Will the HEATIT ET-21 work with my existing 120 V engine block heater rated at 1800 watts?
The ET-21 supports up to 1800 watts at 120 V, so a 1800 watt engine block heater is within the rated maximum output for heating.
How can I verify the HEATIT ET-21 is operating correctly after plugging it in?
Place the unit in a freezer for 45 minutes, then plug it in; the red indicator light should illuminate when the ambient temperature drops below 38 °F and the outlet is energised.
What comes in the box with the HEATIT ET-21 and what must I provide separately?
The package contains one ET-21 thermostat outlet; you must supply a standard 120 V electrical outlet and the heating device you wish to control.
