Learn BTU - Watt Conversion Using a Toaster w/ Ty Branaman

Ty Branaman gives the Kalos apprentices a lesson on BTU-watt conversion using a toaster. (Check out Ty’s KZbin channel at www.youtube.co...)
Toasters are electrical conversion devices that transform electricity into heat. However, toasters are excellent training tools because they also contain contactors, levers, and terminals that are easy to observe in action.
Toasters also have a bimetal device on the inside. Bimetal devices are composed of two metals, and the device begins to warp when it comes into contact with heat. An example of a bimetal device in HVAC is the Snap Disc or snap switch thermostat.
As that bimetal device on the toaster warps, it also energizes an electromagnet, which props the toast out when it is ready. So, toasters are great learning tools for HVAC apprentices because they have so many parts in common with HVAC equipment. You can essentially turn the toaster into a heater by attaching a fan to it. The bimetal device would also act as a safety device if the toaster were attached to a fan.
In toasters, wattage (power) gets converted into BTUs of heat energy. Each watt yields 3.413 BTUs of heat energy. If a toaster were to use 900 watts of power, it would yield more than 3000 BTUs of heat energy.
In the HVAC industry, we perform load calculations to determine how many BTUs of heat our equipment must move (such as Manual J calculations). So, hypothetically, we could use these calculations to determine how many toasters could provide heat to a home. It’s impractical to use so many toasters with fans, but the wattage costs the same regardless of if you use several toasters to heat a home or a typical HVAC electric heater. The expense will come with energy efficiency, as large HVAC fan motors have become much more efficient in recent years.

Watt a good teacher

[@gyrgrls]

Does it relay matter how we heat our space? Wire we concerned about this? I never had very many fans, but with enough of these, my house would be toasty warm. This could even work on a train, with conductors running between cars. I have enough bread for a pallet of these...

[@realSamAndrew]

@@gyrgrls you're a gas. I got a charge out of that. I'm positive.

[@hkhsm359]

Ty is the legend of HVAC teaching

[@tedlahm5740]

Both the same exactly. A watt is a watt. Wonderful video. Thank you.

[@coldfinger459sub0]

If Ty was my grammar school science teacher he would’ve been my favorite teacher. We need more instructors like this in public schools.

[@hubercats]

I agree. Ty is a great teacher!

[@ninamcclure2193]

That was pretty cool to see that a toaster is basically a little mini furnace lol. I have been trying to learn a/c voltage for a little while now. I've been to 2 automotive schools and got DC volts down pretty good. Ac trips me up now and again because it's hard for me to imagine how its flowing through a system. My brain wants to see it work like a battery and it's hard to turn that off. I'm getting there though with the help of you guys explaining things. Thank you so much.

[@thunnasalbako6095]

Very useful information thank you very much sir. I like you teaching style keep it up

[@NoeArauz]

8:03 Slow clap... "Nickle-Back" I got it... :P

[@johnblaisdell2179]

LOL. can't get your Nickleback.... Very Good

[@shubhamsaini8285]

Thanku..

Video shooting from long distance so we couldn't see which component what its work

[@MrElemonator]

I’m curious about the Dyson fan moving air without blades and how the energy consumption is compared to a traditional fan.

[@335alien335]

I'd love it if someone could explain how a nickel caught in the heating element should cause current flow when it wasn't called for. If the heater was driven by 240 volts off of a single pole contactor, I could see it. But wouldn't something like that be normally powered through a 2 pole contactor? Or is it customary for the HVAC industry to leave one side of the heater hot?

[@love2hvac]

In the old days we only broke one side of the heat element circuit with a sequencer or contactor. The new ones are now breaking both sides.

[@shine-cg9uf]

Awesome 👌. Could u use 1 watt = 3.413 to find overall system btu capacity. For example a refrigeration system w= v × a so 120v × 15a = 1800w. Then 1800w × 3.413 = 614.34 btu. Am I in the ballpark or parking lot?

[@ZapAndersson]

1 Watt is ***NOT*** 3.413 BTU. It's 3.413 BTU per HOUR. Goddamnit.

[@fredtayler7106]

ZapAndersson, you must be right. There must be some time component as 1 Watt left on for 0 seconds makes 0 BTU. After all, I can hold on to a 100 Watt soldering iron if it's turned on for zero seconds.
