Some additional information! Firstly, two-stage heating is _sorta_ common so the notion that "there is no medium blast" is _probably_ true but if you have a fancy pants HVAC system, then maybe cranking the heat up _might_ make it go faster. No idea what percentage of homes have a two stage heating system, but I'd guess it's in the 10-20% range. In re: the thermostat wire question. Apparently, to this day, the current going through the contactors that actually turn on the high current loads such as your A/C or an electric furnace's heating elements is carried through the thermostat. So, it's more than just color coding; they are designed to carry some current, and thus need to be a minimum wire gauge. So while Cat5 cable or similar would probably work for most HVAC systems, it might not be able to carry enough current for others (and could, potentially, pose a fire risk under the right circumstances). On that note, and I'm mad at myself for not bringing this up, you might have noticed that in the mechanical thermostat, a separate insulated wire connects the R terminal to the contact on the bimetallic strip. This prevents the current from being carried through the bimetallic strip, which could inadvertently heat it up and prematurely stop the furnace. Neat!

@tfofurn 5 лет назад

I have a two-stage furnace, but not a two-stage-aware thermostat. The furnace installer couldn't be bothered to run a cable with more strands, but assured me that the furnace activates the second stage if the thermostat asks for heat for more than a few minutes. I wish I had invested in a 96% furnace instead.

@wellivea1 5 лет назад

I'm not sure it's the same theory when someone is cold. Trying to warm up from freezing temps at 70f will take longer than 80f. Having 80f will warm the body up faster than 70f. It won't make the furnace get to 80 faster, it warms the body up faster.

As far as "frightfully ancient" goes, I met a woman living in an old farm house with radiant heat whose 1920s boiler was converted from coal to gas long ago. She said that she needed to "get rid of the old thing and upgrade." Her bill for heating her entire farm house was $20 cheaper than my bill for heating a downstairs flat with a 10 year old high efficiency furnace. I told her to keep it.

@leogrievous 8 месяцев назад

@@stitchfinger7678I mean to be fair. Excluding heat pumps. Energy is energy. Burning gas in a modern heater vs a 1920s heater isnt magically going to create more heat and be "more efficient". What really has come a long way is insulation. Last year We've moved into a brand new house here in Germany, highest insulation rating and all. How little heat we need to stay warm is comical. You can basically stay in a room for 20mins, and just from the body heat, the temperature will have risen a couple of degrees.

@ZeldaTheSwordsman 2 месяца назад

@@leogrievousI mean, undoubtedly a number of older designs probably weren't the best at _transmitting_ all the heat they produced through the system and heating the _rest_ of the house. In this case, the difference-maker is probably that the system is boiler-powered rather than forced-air furnace.

@TheMinecraftACMan 3 года назад

HVAC Tech here. Wanna hear a fun story about a furnace that kept blowing its fuse? Yeah, there was a short somewhere on the board in the common side of the circuit, so whenever you connected the common to the thermostat, the fuse would blow. This originally started as me trying to install a Nest thermostat. Imagine hiring an expert to install a new thermostat, only to be told that your furnace needs a new control board. Yeah, the homeowner wasn't happy. I did manage to work out a hackey solution though, that involved wiring the common directly to the common side of the transformer. I should point out that this is NOT a proper solution, and was only a workaround for this specific scenario. If the homeowner's system had also had air conditioning, then this would have been discovered sooner, as well as not been solved this way. For those non experts out there: the circuit that turns on the outdoor condenser unit on a standard split-system AC is also wired to the common terminal on the furnace control board. Were it present, the fuse would have been blowing every time the AC came on. But this was in Breckenridge Colorado, in the house of someone who (rightly) figured that it would be cheaper to run a window unit for the couple months each year that actually required any kind of AC. Because the common was previously unused, I'm at a bit of a loss to how it shorted in the first place, though the two potentials that come to mind are manufacturing defect, or perhaps corrosion on the board.

@vaseasun 2 года назад

For those of us where heat pumps are common: the Emergency Heat electric heat strips are also called "Aux Heat". On even basic 30-year-old thermostats, Aux Heat is usually triggered if the setpoint temperature is 3 deg F above actual temperature. In this instance, turning the thermostat up above a 3 degree delta will actually heat faster, but use much more electricity.

@StrokeMahEgo 2 года назад

I've seen places where "heat" is the heat pump, and "aux heat" or "emg. Heat" are from a gas furnace. Which is probably a decent idea for places with poor electrical infrastructure, where a lot of resistive heat might break the grid. (Like, say, Texas)

@itptires 2 года назад

Yes exactly this. And much more difficult to find Smart thermostats and programmable thermostats. We have a heat pump with a relatively basic digital thermostat but it's not programmable or anything, have a new programmable one just waiting to install will be so nice, because right now I wake up in the morning and turn the thermostat up 2° then wait 20 or 30 minutes and turn it up another 2°. Just to avoid triggering the "Aux" heat. Can't wait to program with the app a nice smooth increase

My ears perked up when he mentioned how thermostats can be compared to really slow Pulse Width Modulation (PWM). That's a very smart comparison! I was installing LED strip lighting under my cabinets and needed to install a PWM dimmer. I only knew I needed one, but my curiosity got the best of me, and I just had to research how exactly they work. It's a fascinating concept, essentially flashing LEDs rapidly enough to trick your eyes into thinking it's a "dimmer" light. This concept of eye trickery seems to be a common theme with Technology Connections (such as in the awesome mechanical and analog television demonstrations), and I find it interesting how we can take advantage of what our human eyesight cannot see. Anyway, back the topic of THIS video, excellent job describing the simple, necessary, and ingenious technology behind thermostats!

That blue wire just trigger my OCD… as an HVAC engineer it is improperly installed. I do gas steam boilers in NYC, that’s 95% of our heating solutions and it’s 98% more efficient than anything else as steam heating with radiators are always going to maintain heat even if you open the door for 10 minutes. This video is amazing though. You explained everything so everyone can understand. I’ll use this video to show my class next week. P.s. always stay away from mercury thermostats! If anyone reading this has one please change it. You can do it yourself safely even if you can’t reach the boiler to shut off the emergency shutoff. However I always recommend it and always take a picture before you start. Also you only need two wires for steam gas boilers. If you’re installing a smart thermostat we use blue for power to charge the battery such as Nest thermostats. This can be done directly from your boiler or via a DC power source.

@TheLawrenceWade 3 года назад

The last comment on a mode where the thermostat goes to a new set temperature after you've mowed the lawn: That would be the "Hold" mode on most Honeywells programmables. Just hit the temperature buttons up or down and it will hold the new temperature for 2 hours, then resume its program. You can also set the Hold mode for longer periods, perfect if you're going away on vacation for two weeks, let's say. Thermostat wire is special. I live in Canada, but things are similar in much of the United States. If the thermostat fails, your furnace never gets the call for heat and your pipes freeze causing a huge amount of flood damage. The wire is low-voltage rated and has a FT rating printed on the jacket - that's Flame Travel, to tell you whether or not a furnace fire can spread to the rest of your home via burning thermostat wires. Also, being different enough from ordinary NMD house wiring, it's hopeful no one would try to connect a household thermostat directly to the 120V line - but it does happen where baseboard heaters are common. Don't trust the wire colors as standards - they should be but they're not. Always label the wires as you take them off the old one and put them on the new one. If you lost track, go down to the furnace and look at the control board. The R terminal on the furnace must be connected to the R terminal on the thermostat, and so forth. When you run into W1, W2, W3 or Y1, Y2, Y3, you're dealing with a multistage setup. They're becoming common on high-efficiency residential furnaces here in the snowbelt. W1 turns on the furnace, one burner. W1 and W2 turns on the furnace with two burners.... you get the idea. Multistage heat is a lot more common than multistage AC because gas valves and igniters are cheaper than compressors and condensers, but you might see multistage AC moving into places where there have been energy efficiency incentives. Take your old mercury-bulb or other pure mechanical thermostat and mount it in the utility room where your water service enters your house. Set it to heat and set it at an indoor temperature you'd find unpleasantly cold - lowest setting. Connect its R and W terminals in parallel with your new programmable or smart thermostat, you might even be able to run the wires directly to the furnace. Your old thermostat will be there silently ready to command the furnace to turn on if your new thermostat gets dead batteries or suffers a software crash (or a hack!) while you're away on a ski vacation. It will keep your pipes from freezing.

@coreypowers2988 3 года назад

Regarding the temporary change to the cycle commands (question at the end): it's not exactly the same, but some of Honeywell's "dumb" thermostats that have a scheduling function can sorta kinda work like this. I used to have one on a M-F and weekend schedule. Adjusting the temperature control outside of the scheduling would result in it running the heat to the new temperature but it would reset to the schedule at the next scheduling increment. This could be greater than just like a half hour or so (or 5min if it's right before the next scheduling increment), so different. But it did allow you to make a temporary change and the thermostat would correct itself automatically in time

I Service HVAC systems on passenger trains, and everything is preset and automatically controlled. The system is set to run the heat or A.C. as needed to achieve the preset temperature. There is no way to change it other than turning off breakers, which are located under the train car. They do include an override button, that runs the A.C. for 20 minutes to cool off the car in the event there are a lot of passengers. 100 people have a lot of BTUs of heat. I thought I'd provide that little bit of insight since you asked of anyone knew of a thermostat with the feature of running and then returning to the set temperature.

@phils4634 5 лет назад

Something that most people don't realise. The average human generates about 100w of heat, so a train carriage full of your 100 people (probably relatively lightly-clad since it's warm) will generate 10kW heat (which is approaching the rated capacity of many "whole-house" ducted a/c systems). Add in thermal gain from the exterior (heat leakage via windows, opening doors, and solar gain from roof irradiance) and the a/c requirements can be very significant indeed.

@phils4634 5 лет назад

@@Shaun.Stephens Surprisingly, YES! Your basal metabolism produces about 100W heat even sitting still, and exercise (even gentle walking) can easily add another 100w. There have been a number of physiology papers indicating that you can train your body to tolerate pretty low temperatures without shivering, and this seems to be related to increasing the number of Brown Fat cells - these are very important in a process called "non-shivering theremogenesis", and people who live in colder climates have a lot of them. If you can manage to tolerate cooler conditions (especially at night), you can encourage production of brown fat cells, and in effect lose weight whilst you sleep (in theory at least). The problem is that we're also hard-wired to crave more calories as the temperatures drop, so you'll also have to be careful with what you eat. This reflex response to cold is the major reason why people gain weight over winter (our bodies are programmed to maximise energy stores under such conditions).

The bimetallic coil would expand and contract, tilting the vial and making or breaking contact between the electrodes. Aaaaaand I just finished the video. You covered it in the end. 😅

I’m in the UK and many thermostats here do have a “One-Cycle” mode. It’s usually denoted on thermostats by a button labelled as “+1 HR” and overrides the temperature sensor and enables the heating for a set 60 minutes.

@iAmTheSquidThing 5 лет назад

Yeah, Hive has a "Boost" mode where you set a temperature for a certain length of time. It's actually a bit of a misnomer though, because you can "boost" the temperature lower as well as higher.

@Ice_Karma 5 лет назад

@@iAmTheSquidThing Perhaps it's "the impact of the combined HVAC system" that's "boost"ed, instead of "the temperature"?

I used to work at Menards (think Home Depot or :Lowes but limited to the upper midwest). Had many people ask about an "Express" setting when shopping for a new thermostat. Pretty much gave the same explanation as the video that it is a longer run time that gives a longer temperature swing.

@johnfrancisdoe1563 5 лет назад

Rick White Actually depends on the physical layout. If the thermostat is located between you and where the heating/cooling is, telling the thermostat to make it hotter / colder where IT is will change how fast it gets hotter / colder where YOU are. Other similar situations exist. Of cause if the difference between the "turn on/off now" points is large enough, it might oversteer enough to get your location hot/cold enough anyway.

@Pheratia 3 года назад

My apartment has electric baseboard heaters which when we moved in had mechanical thermoatats which only turned them on and off at full blast. But since the thermostats controlled the full voltage directly, i was able to replace them with digital thermostats with variable voltage control, giving far closer temperature accuracy and much more energy savings due to tapering off the voltage the closer it got to the target temperature and avoiding overshooting the target. So our thermostats do regulate the amount of heat coming from the heaters.

@pianofitz 2 года назад

The Honeywell RLV4305 -- I have three of them in my house, they replaced older mercury-bulb and other mechanical thermostats -- is designed for electric baseboard heat installations in which the thermostat switches the actual line voltage of the heater (120V or 240V) rather than switching 24V signal-relay voltage. The RLV4305 uses a triac to power on or power off the load, and this being electronic, the heat can be turned on and off rapidly. This is EXACTLY the fractional control method described in the video -- Duty Cycle. The RLV4305 has four levels of heat it can command. If the ambient temperature is way below the set point, it will just turn the heat ON. "Full blast." If the room is only a degree too cold, the thermostat can instead run the heat at 75% power, or 50% power, or even 25%, which low power is also used to maintain the current room temperature once the set point is reached. Overall, this allows the desired temperature to be maintained with smaller temperature swings than you get with an all-on/all-off thermostat. Most "smart" thermostats like the Nest are designed to work with 24V switching systems, and thus are ONLY all-on/all-off. But, I believe that the Mysa brand of smart thermostat has a model with triac line-voltage switching for baseboard electric heat, which can do the same multiple-levels-of-heat control.

@@pianofitz My Nest does turn my gas furnace on and off with a short PWM cycle, which provides proportional control and gives a very even temperature.

8:00 from what I've seen of industrial processes in my line of work, ordering a mold for injection is what sets you back the most in terms of R&D budget for that kind of extremely simple device. IMHO, it's not "too cheap" but rather "pretty smart" (and quite "normal" too)! :-)
