Essential Info

Plug your appliance into the cold weather Thermo Cube and plug it into the wall. When the temperature drops below 35° the Thermo Cube will turn your appliance ON. When the temperature raises up past 45° it will turn your appliance OFF. Each unit has two receptacles for use with more than one device. Can operate loads up to 1800 Watts, 15 Amps, 120VAC. The Thermo Cube is also available with different temperature ranges to suit your specific needs. It is recommended that the Thermo Cube is used with GFCI outlets.


What's Included

  • 1x - Thermo Cube - 35° ON/45° OFF
  • More Info

    Use this Thermo Cube to automate self-regulating heat tape, heat lamps, stock tank heaters, pond de-icers, engine-block heaters. If it gets too cold in the attic because the pilot light blew out when gas service was interrupted, you can have it turn on a space heater. You can even use the Thermo Cube with a strobe light to create a "Freeze Warning" system that can be seen by neighboring homes or buildings.

    Using this to control the water pipe heater in my garage. Wish I would have had this earlier to avoid the damage from a freeze.

    MARSHALL -- milan, MI   12/5/2013
    Works great and less expensive from previous models I have purchased.
    DAVID -- wilson, NC   12/1/2013
    Great product. I bought one ten years ago and is still working fine. Needed one for another location.
    CYNTHIA -- santa fe, NM   11/17/2013
    Great product, just what I needed to keep the water in my chicken coop from freezing overnight and keeping my electric bill down during the day!
    JACK -- enid, OK   10/1/2013
    Product received on time. EASY TO USE
    DAVID -- butte, MT   2/28/2013
    Works very well to protect my basment water system from freezing in adverse conditions. Heating as necessary also saves on the uyility bills.
    KAREN -- lowndesboro, AL   2/25/2013
    These work great. Especially if you are not around when bad hits
    RUSSELL S. -- coalville, UT   2/10/2013
    They work just fine, but they are too wide to use in a weatherproof outlet. Rather than go two outlets across go either just one or have them vertical.
    Briar Patch Farm -- walkerton, Indiana   2/4/2013
    I have been using this to control a heat lamp in my chicken coop, a heating mat for their water, and also a heated pet water bowl. For the latter, it turns it off a liittle sooner than it would alone, saving evaporation loss. I,m trying to come up with a way to hook heat tape to it, inside a box, for eggs for my self serve customers, to keep eggs from freezing. Wish the range was more like 35 to 40 degrees for this purpose. Anyone have ideas how to make it work? Thanks
    SIDNEY -- comanche, TX   1/3/2013
    First order and am thoroughly pleased and satisfied with all aspects of the process. Rapid shipping speed and excellent service. Will definitely order again when the need arises.
    CHARLES -- moriarty, NM   12/30/2012
    Love this item. Just a note: cube shuts off at 35 degrees, otherwise if temp is lower it is on...even below 35. I use this item with a ceramic heat lamp.
    CATHY -- dundurn, SK   12/11/2012
    Very pleased with this item. Received it promptly and it does exactly what it's supposed to. My chickens are very happy with a more consistent heat than I could provide with a timer.
    MIKE -- el cajon, CA   12/9/2012
    Gosh, Delivery was amazing fast. It arrived the day after I ordered. I was amazed.
    DARRELL -- norwood, NC   12/2/2012
    works great
    ROBERT -- meridian, MS   12/2/2012
    I looked for this item for some time. It is great for keeping a small amount of heat in an area such as a "pump house" for those homes that do not have or use community water. The Thermo Cube along with a 1500 watt heater does the job.
    RICHARD -- clarkesville, GA   11/16/2012
    great product
