Thermo Cube Thermostatically Controlled Outlet

Read the reviews on Amazon. With 16% one-star, I wouldn't buy it. We a thermostat like the Frost King.

I use it in several places. Works for me with a 60 watt bulb and a clamp on light fixture with an alum reflector.

frostking looks much more robust

I've been using a thermos cube for over a year now, so far no problem. I have 60 watt light bulb in my wet bay to keep things from freezing. Outside temps get down into the teens some nights.

I have recently started using them with good results. I would like to know how much amperage eHoefler was running through his. Regardless, switch life is greatly shortened by high amperage. Also, a high amperage heater will make it switch more frequently than a smaller heater, further reducing switch life. Staying with as small of heater as you are comfortable with will help on both issues. I like that the Thermo Cube has a second outlet. They suggest using it for an indicator light so that you can visually confirm that it is still working. I put my heater as far from the Thermo Cube as I could to be sure that the entire compartment got warm and to reduce cycling. I did choose a heater with a thermostat I set for 90 degrees to be sure that I don't overheat that spot of the compartment.

The most common Thermo Cubes come on at 35 degrees to prevent freezing, other temperatures are available if you want to keep things a little warmer.

I use one in my house. There is an area the pipes will freeze when the temps get in the low 20's and the wind kicks up.

I use an incandescent 60 watt bulb plugged into the Thermocube. It's been working for a couple years.
Eventually, I'll insulate the area so it's not needed.

The Thermocube does a good job, I would not hesitate to use in in the RV or anywhere else you want freeze protection..

I've used this type for several years. Pretty much the same thing...on at 35 and off at 45.

I quit using them, have had several well houses freeze from them failing.
