This review is from: Farm Innovators TC-3 Cold Weather Thermo Cube Thermostatically Controlled Outlet - On at 35-Degrees/Off at 45-Degrees (Lawn & Patio)

I've used this ThermoCube for a few years to protect some vulnerable water pipes in an otherwise unheated shed.

There are several cosmetically-identical versions. The TC-3 model (on this page) is designed to turn on at 35F and off at 45F, which is pretty critical information that should be in the product description. It's rated 15amps and 1800 watts according to [...], which sells these for over [...] each.

I've been using this device to switch a radiant oil heater. The new ones will control 250-watt brooder heat lamps. If you're worried about pipes freezing, it's cheap enough and simple enough to be worth a try.

It gets 4 stars because the temp sensor is not accurate (on at 38F) and there's no indicator lamp confirming the device is getting power from the outlet.

3.0 out of 5 stars Does what it says, but poor design for an outside outlet., February 4, 2010

This review is from: Farm Innovators TC-3 Cold Weather Thermo Cube Thermostatically Controlled Outlet - On at 35-Degrees/Off at 45-Degrees (Lawn & Patio)

Seems to work as stated, but if you have a use for this in an outside recepticle as I did,(heated water bowel and a bird bath heater), then reconsider!! All my outside outlets have a metal weather cap an the top and this cube is too large and hits the weather cap, so it does not plug all the way into the outlet. Bigtime unsafe seeing the prongs exposed!! Cost half as much as what I paid for the thing to send it back so I found a very short, but HD outside extension cord and plugged that in to the recepticle and the cube into that. Then put it in a waterproof bag sealing it up. Better than letting the prongs hanging out. Someone really dropped the ball when they designed this for "outside" use! They should have designed this body slimmer on the top.
