How to Make a Thermostat Controlled Extension Cord

Thermostat:

Extension cord:

I made this to control the temperature of a small area that I use for wine making. Splicing a thermostat into a short extension cord and plugging in a light bulb to produce heat, controlled by the thermostat.

Someone give this man the Nobel Peace Prize Award ! Job well done, if only you knew just how greatful I am that you took the time to educate us on this wonderful idea. I can't thank you enough, such a simple concept, that I would of spend months trying to solve. Thank you sir.

[@warrenhardy]

Thanks. I’ve made a couple of these for different reasons. Like keeping my water pump from freezing, I also bought reptile heating coils instead of using a light bulb.

[@BurtDavis]

Great idea. I'll use your idea to make a temp controlled fan for my garage.

[@Conqueef-tadoor]

Thanks for this informative video! 👍👍 I need to make one of those for my dog. I have a heat lamp out in his doghouse and instead of having it on 24/7 in the winter, I can have it turn off if it gets too warm.

[@robertgreen4050]

Bring him in the house

[@98ricochet47]

I have the same issue. Old incontinent dog who loves life but I can’t keep in the house anymore. A 24/7 heat lamp gets very expensive

[@normanpowell6831]

This is actually pretty simple. I have an application that I would like to use this on. An oil-filled electric heater. The built-in thermostats are highly irregular and do not sense room temperature. The problem is a device which could handle the wattage. The max would be about 1,800 watts. I would have to use a "line" thermostat that could handle 15 amps at 120 VAC. Other than that, I think this would work quite well.

[@royross6281]

A relay would make it possible

[@DayClanTribe]

I found some old resistance heat wire units that screw into light socket in place of light bulb that would work great for that and use more watts for heat and less wasted as light. Great setup there BTW. Very handy cord can be used for so many things.

[@warrenhardy]

Nice. Thx

[@TheWickerShireProject]

Warren I love this Idea! Very simple. WickerShire approved! Awesome man keep them idea's flowing!

[@christianbrobst3486]

Thanks for the video. Very helpful and I could t find a good way to do this anywhere until I found this.

[@bobsillas3553]

I went to Good Will got a hair dryer put a thermostat on it set it to warm worked good

[@warrenhardy]

nice ingenuity

[@JimDugan]

Excellent. I'm looking to make a bread proofing box. This will do nicely.

[@kevinlemaster8958]

Wonder if this would work with a torpedo heater

[@rogeliolopez2190]

Thank you I thought I was going to also need to use a receptical but hey why not use the cable it self

[@nathandecker2894]

is this a high voltage thermostat?

[@haleydale8]

Great information and video. Thanks !

[@cb7538]

A double pole can be shut off manually on the thermostat. A single pole can only be shut off completely by unplugging your cord.

[@warrenhardy]

good to know, thank you

[@tier3rd375]

Double pole means 2 switches. A single pole uses 1 switch to control 1 hot wire. A double pole uses 2 switches for controlling 2 hot wires. The video showed a single pole thermostat controlling a 120 volt load, which is okay. If it were controlling 240 volts, it needs a double pole to control both of the hot wires for the 240 volts.

[@JonWchannel-bg8in]

Warren Hardy, my name is Jon, I really liked this video and is exactly what I was looking for to a project however I was wondering if you could make a video on how it’s done with a digital low voltage thermostat to? I want to do everything just like you did in this video but by using a low voltage digital thermostat. I am sure I would need to use a transformer or 2 different transformers. I was going to plug into the plug end part a 1500 watt electric ceramic space heater into the plug end of the thermostat controlled Extension cord.

[@ianwilson3495]

You only need a single pole on 120 volt circuit and a double pole on 208 volt circuit.

[@temurpirnazarov8874]

Is it good to use this kind of hand made controler cord for weber electric grill 2400?

[@vmaxmadness66]

Where did you get the thermostat?

[@robbobcat7286]

the door in the closet is upside down..lol

[@rogeliolopez2190]

Tip if you are in the us they rarely sell theese and less the cooling ones so I had to get relays to use it

[@OldBenOne]

It was not specified that this must be a line voltage thermostat. the thermostat and box were not grounded, therefore electrocution and fire could occur from any fault (crushed wire, failed thermostat, overheating) which if wired properly would have tripped the breaker. Also, some of the conductors were cut too short. And an incandescent bulb in an enclosed space causes house fires. This one will occur sooner, whens something falls over on the bulb.

[@calvinpatrick9948]

Been doing this for years for my snake cages. Works great

[@user-ec6yk1fz3k]

That's what im hear to plan out. Do you have a way i can contact you for questions?

[@jenesisonetwentynine5843]

You need to tag this video for #reptilelighting. Thanks for the info!

[@TheWickerShireProject]

Great idea! Nice hash tag too!

[@coachwhitford7315]

Good ol Canadian ingenuity!

[@whydoineedtohaveacct]

fyi Warren they sell these, all you do is set temp and add plug but thanks for the video, shows that it can be done this way too and i'm guessing could use a programmable thermostat the same way

[@warrenhardy]

+whydoineedtohaveacct I like your handle!

[@tyronejones4105]

whydoineedtohaveacct they don't make line voltage programmable thermostats. Have to have relay and transformer and low voltage tstat.

[@mikep6731]

Yes they do. Look on Amazon for LUX Win100 programmable line voltage thermostat.

[@rogerhodges9721]

@@mikep6731 Yep!

[@cloverbee9656]

is it possible to install two thermostats into one outlet? I want to have a thermostat run a fan if it gets too hot or if it gets too cold.

[@warrenhardy]

No sure, let us know.

[@mikebaca6312]

Clover Bee You can do this with a temperature controlled outlet. Can find them on Amazon for about $30

[@katherineking8247]

This would work for a homemade incubator.

[@race4survivalisalive800]

I just bought a mini car heater that plugs into the 12V cigarette power supply. It only has an on/ off switch. Is it possible to install a small thermostat to something like that? It only has the two wires unlike the one in this video. What kind would you recommend. Thanks.

[@jeanboisleduc5255]

you cant heat properly through accessory receptacle, dontwaste money there, get the heater fixed

[@geyser3445]

Could you use a "Honeywell Winter Watchman" and simply plug the little electric heater into this "Watchman"?

[@warrenhardy]

never heard of it, but now I have to look into this, thanks

[@shawnm8232]

The "Honeywell Winter Watchman" is only rated for 120 watts. A Lux WIN100 would work though.

[@ianwilson3495]

The box should be grounded with the green wire.

[@otrotland5377]

I have a box fan that I added a thermostat to, the fan (box fan) has three speed settings, is there a way to have the low speed come on 50 degrees and high speed come on at 90 degrees

[@rogeliolopez2190]

You will have to make a switch for that

[@ojosrojos842]

Me too

[@whiteboy2600]

thanks for the help your video thumbs up bro i made one + a video on it & said your name to where i seen this setup well you have a great night & day thumbs up video will be out later

[@warrenhardy]

Nice. Thx

[@whiteboy2600]

Warren Hardy thanks for reminding me forgot to do the video but now I'm working on it be up today well thanks & have a great day

[@jonw.2594]

I want to do the same thing as you did in this video and i bought a thermostat just like this one however i just noticed that my thermostat that i just bought today has 4 wires and there are 2 Black hot wires or mabey even 4 Black wires and then 2 or 3 Red wires, it might be a double pole or something but am not for sure. How do i do this project just like you did in this video? there thermostat i have looks just like this one however has 4 wires total or less but it does not have 2 Black hot wires on the back either.

[@warrenhardy]

Not sure on that

[@rogeliolopez2190]

It's either a heat and cool thermostat or or for interupting both negative and positive

[@zackgarrit5654]

This Stelpro thermostat, the key to this project, is not available at any hardware store, farm & pet store, Walmart or Homedepot in the Sacramento area, but Stelpro provided the name of a source (Home Electrical) which has sent one after I paid them $25 for it, not $12 as mentioned in this video.

[@zackgarrit5654]

A hint to makers of videos: you don't need to show every little step in such a process, such as stripping the wires, searching for stuff, etc., etc., and you might want to provide a hint about where any special equipment might be obtained.

[@warrenhardy]

yes a little long winded, and yes I'm in Canada, and the thermostat is a common thing to buy at any of the hardware stores around here.

[@efryeii]

It is a common single pole Baseboard heat thermostat. 120 volt

[@skeezerjohnson5623]

It could be quite easy for the novice to confuse 24v thermostats for the type used here. Using a 24v for this type service could result in a fire. I found the 120v thermostats at my local home center stocked away from 24v thermostats, to where they sell electric baseboard type heaters.

[@VtecdippinBB6siR]

That's how it is in california though.

[@RubbinRobbin]

What are the applications for this?

[@warrenhardy]

personally I use this at my cottage to keep a small 5 x 4 x 4 room that contains my water pump and pressure tank warm through the winter months. only difference is that I power 2 reptile heat lamps with it instead of a light bulb

[@NotSoCrazyNinja]

How can anyone hear you? I have my volume all the way up (including an 11dB boost) and I can't hear you.

[@MakeAbortionNonpolitical]

Maybe keep feral kitties warm.

[@meganbrushett7387]

What voltage is the thermostat you used

[@Andy-df5fj]

Line voltage. 115 volts

[@DeathbringerDrago]

Dude why not tell the model of the thermostat I need this thing lol/

[@timothyneumann7857]

You know it is a lot easier if you thread the cut ends of the cord through the box connectors before stripping the wire ends.

[@tyronejones4105]

17°?! Where the fuck u at an igloo???

[@giG_apP_haCks_]

17 degrees CELSIUS = 62.6 Fahrenheit 63 degrees is a bit chilly for indoors, but hardly an "igloo". The rest of the world, including Canada, has adopted the metric system. We (US) should too.

[@Flowshow88]

Just buy a cord for a griddle 😅

[@warrenhardy]

I wonder where the temperature sensor is in a griddle cord
