The heart of the heating and cooling system will be a heat pump. This Old House plumbing and heating expert Richard Trethewey uses a mock up and props to show host Kevin O’Connor the mechanics of the latest state of the art heating and cooling system. Heat pumps have compressors, valves, and fans that regulate speed and opening so a system can evenly maintain itself and keep temperatures steady to the exact degree.

How a Heat Pump Works
/ thisoldhouse - Хобби
I have been in the hvac field for about 15 years and this is by far the best way that I have heard the refrigeration cycle explained. Richard you are awesome
12 years for me and I couldn't agree more
You're still an apprentice.
5 years and same hahs
And complex formula wow
I just got a heat pump and the genius of this makes me feel better about the money I spent. I ACTUALLY understand it.
I just graduated USF with a degree in mechanical engineering. Should have watched this before my first Thermo class. Good stuff.
Just getting into this material in my Thermo series for Mech E., and yeah, this video really brings it home in a way that's understandable.
I’m a mechanical engineering student now and I’m taking thermodynamics this coming semester lol good thing I’m here lol
There's a joke here about which college to attend, etc. But agree, these "basics" I feel like should be a preface into what textbooks show. In only a couple of minutes they give a very good explanation of how something works. There's also a comment regarding teachers and tuition, but it would quickly arrive at the Good Will Hunting summary of “...wast[ing] $150,000 on an education you coulda got for $1.50 in late fees at the public library.”
USF alumni represent GOO BULLS!
Go Bulls!
I’m in HVAC field myself for ten years and this guy explains it better than I’ve ever heard it explained
Richard really has a talent for teaching. You can tell that he enjoys explaining it, and also understands the concept so well that he can easily dumb it down for the rest of us.
I have found that the people that aren't able to dumb down a subject, either don't know the subject, or are full of it.
I’m studying 1st year engineering and you’ve just done a better job of explaining half of the thermodynamics I need to know this semester than the (very expensive) textbook. Thank you!
I might have to watch this a dozen times before it sinks in.
I agree, the explanation wasn't very good. He talks too fast and skips too much by not giving context.
Which brings me to my next point dont do drugs
I really enjoy Richard's cutaway models, they really clearly explain plumbing parts that I would never understand otherwise!
I’ve worked automotive air conditioning all my life,but this heat pump system was somewhat complicated….until now.Thanks to you Richard,all it takes is a switching valve and some electronics.Now I can even explain it to someone else.You get the credit of course.
Like listening to a good teacher, concisely and clearly explains thermodynamics with no-nonsense. Thank you
This video is pure gold. Never in my life HVAC has been so well explained. Thanks!
king richard! being in the hvac field myself i can say that the future of comfort is exciting. i love seeing how you explain things. i want to be like you when i grow up 😀
Such an astonishing coach! Simple crisp memorable - genius at work I love this show!
Great video I’ve been in HVAC many years and this guys explains it all so well. Brilliant well done.
This is an amazing and simple explanation. For the first time this concept makes sense! Thanks very much!
Great job Richard!! I just want to echo what a few other people have said. I have never been able to wrap my head around how a heat pump & Air conditioner work. And here in South Carolina....EVERYBODY has one. What made things so clear for me was not only did you break it down explaining it. You also had the visuals that everyone could see. Outstanding sir......you da man!
8:08 - Kevin O'Connor said it PERFECTLY, IMO.
WOW.
Thank you This Old House's Richard Trethewey .
Great explanation. I was always curious if TOH would put out a more detailed video on the principle behind this technology. Getting one next year. Thanks for the videos! Keep them coming!
Richard, thank you for explaining the operation so aptly; even I, a non-techi can understand it. Brilliant!
THE best explanation I have seen for any heat pump (AC, air source, geothermal). Well done!
I have seen many videos of how an air conditioner works, but this is the best explanation I have ever seen. Now it totally makes sense
What a good explanation. Nothing like someone who knows what they are talking about, and able to communicate it for the average person. Thanks.
I too work in field and this was a great explanation of how archaic yet brilliant these systems are, love your videos!
This Old House for the win!
In all my years as an engineering student, this is THE BEST demonstration of heating, cooling, and basic gas law I’ve ever seen!
Hi from Canada.
This video and audio explanation of Heat Pump/AC was amazing.
The concept was explained very well. Thanks to great mentors like him.👍
That was simply beautiful. Many many thanks 🙏🙏🙏🙏
love the fact that Richard always dissect his mock ups. Make it simple to understand. Great job
The best explanation I have ever seen. Really well explained. Thanks
Those who intimately know their craft can impart it to others in easily understood terms. Great job and many thanks!
You guys are great ,I always was confused as to how heat pump works and you guys made it so simple . Thanks
Hands down one of the best explanations.
This explanation is simply priceless.
That was so clearly explained. Thank you for demystifying.
You are amazing. I'm 64 and never understood this process, because nobody could ever explain it to me so well. Thank you so much :) Maurice
No fancy animations. Just pure old school wisdom!! LOVED THE EXPLANATION. Makes me realize how much real life examples like the canned air are so powerfully effective
This is magnificently explained. Thank you so much!
This was an excellent video. Great explanation and demonstrations.
Thanks for that explanation in detail and also with a visual effect👍
I've been trying to understand this theory FOR YEARS! Finally a great explanation that anyone can understand! I love the examples that explain the compressor and the expansion valve with the can. Thank you so much! This is the best video on the subject by far!
You guys always keep me updated on new products. Thank you 👍
Thank you for explaining that in a way that even I can understand! I knew the principal of it but not how it actually worked.
That was probably an easier and better explanation than like anything I've been watching to learn about this stuff. I think I truly understand the fundamentals of these systems now.
You’ve got it perfectly explained, I love the the enthusiasm
The best explanation of a heat pump I've ever seen. Great job Richard. Your a great teacher.
I taught thermodynamics at the college level for over 35 years. The molecular dynamics for the cooling and heating of gases on expansion and compression are well understood and easily explained in the classroom. However, to put these scientific principles together for the purpose of heat exchange from the outside to inside or inside to outside and make it work in real life is absolutely genius. Richard Trethewey's explanation is simple to understand and masterful. Well done!
Thanks for taking the time to build that model, it made it very easy to understand. Well Done!
I love watching these explanations. Love this show. Richard and Tom are the best.
Finally, after a week of runaround and sophisticated jargon, I heard just what I needed. Thanks, and I believe I am now a "This Old House" super fan.
This show must never go away!
Man I love this channel. You save my life by explaining complex thing in human language. I am so grateful. THANK YOU!
Awesome explanation! Thanks Richard.
Brilliant explanation Sir! I understood it! Thanks for posting.
That was so helpful. Thank you!
Richard you rock mate - brilliant! thank you for sharing guys!
Best explanation I've seen. THANKS!
Best explanation I’ve heard… and not likely to forget again. Thanks!
Came across the video by chance. The guy explained it really well ! 👏👏
What an excellent explanation Richard - First class demonstration. 👏👏
This is the best explanation for the layman. Other videos I've seen on this topic were too technical for my non-mechanically inclined brain. This video was perfect. Thanks.
Best explanation I've come across of how a heat pump works. I like the way it begins with the basic question, "How do you get heat into your house when it's cold outside?"
Awesome demonstration of how it works. Great and easy to think. Thank you.
Fantastic video! Finally learned how these systems work, something that has otherwise always been a mystery to me.
Sir, you guys have just made a best demonstration regarding refrigeration cycle, thank you!
Best explanation on the subject that I've ever heard. Made it really easy to understand. Thank you!
WOW ! 😱
What an amazing explanation and illustration !
Thank you 🙏
Finally an explanation of heat pump technology I can wrap my head around. Thank you!
This is brilliant. I have never understood this until now.
Excellent presentation with a fair amount of technical details!
That is by far the best explanation I have every seen on the refrigeration cycle. I have a question though, does this increase the amount of condensation being produced in the evap coil?
Such an excellent teacher!
Richard, superb yet again. Thank you
Great explanation...First time I've got close to understanding how these things really work and are controlled.
Outstanding explanation of a complicated subject.
Wow. Just wow. You brought this mystery down to an easily understandable treat!
That's the most brilliant video on the internet! A paroxysm of masterclass !
That was fantastic. Thank you so much for that clarity!
Thanks Richard, you're the best.
What a fantastic explanation. Thorough and detailed, and I was able to understand everything. Not that I remember it all, but it certainly makes sense to me now. And, previously I was confused -- as are many people -- as to how a heat pump can cool, but now I see it is all just a matter of moving heat around, in one way it heats a space, and move it the other way and it cools.
thank you very much. you showed me a vaque understanding of heat pump of me made so clear. you are one of the best instructor who I ever have met.
Awesome job explaining that!
Well done guys, great explanation. All the best from the UK 👍
Sometimes when i'm sad I come find this video for the 1000000th time, its that good
A great explanation for anyone, especially for guys like me that grew up being told how awful heat pumps are. It's a hard reputation to overcome.
Awesome learning video guys! Very clear and well understood.
Best video ever about heat pumps.
outstanding explanation of heat pump operation
Thankyou for explaining this in such a understanding presentation .
I live in California and just bought a new home in Florida which has a heat pump, a/c combination. I love this video because I kind of understood that it worked the opposite of
a/c, which I understand how a/c works, but this really cleared it up. I'll find out how well it works when I get into my new home in two weeks! Thanks Richard! I watch ALL the This Old House line up. Have watched for decades.
How’s that working out for you? (Still in CA)
We've been here one year now and there really was no prolonged period of cold last "winter". It's really like a long summer and a short mild fall. There was one week in December, I think, some rare, freak, week-long cold snap hit and it got down to 29° on two or three non consecutive days but maintained daytime temps around 60°-70°and nighttime around 40° and no problem. But we rarely use the heat. It's a Carrier unit. Electricity is cheap here (0.9 cents per kwh) and that's good because you need the a/c ALL the time! Our house is all electric. Our monthly bill averages around $180-200. Thanks for asking and good luck in California. I mean that sincerely. We're born and raised Central Valley. 60 years. We fled the lunacy. Sold our home, left our family and friends and we didn't look back lest we turn into pillars of salt! Lol! We love our new home and the people. Hope you and Pete live long and prosper...
Super clear, concise, well edited.
I understand how an a/c system works. I never realized you could simply reverse flow and get the opposite effect. Great description!
Great explanation of a complicated system.
Most wonderful explanation. Thanks.
Excellent explanation!!! Thank you 😊
This was an amazing video. Thank you for the explainer.
I installed a Carrier Infinity mini split heat pump last spring. It is amazingly comfortable for cooling AND heating. Amazing technology!
What size house did you install this on
@@rockinrobin322 I installed two separate 12000 BTU units on each apartment of a duplex. Each unit is 1500 square feet.
Another question: What's the winter weather like where you installed this? How cold can it get, and does the system work all winter to heat? I'm in Iowa, zone 5b. Probably a heat pump would not work in the very coldest months, I'm thinking.
@@aprilm9551 Winter is harsh here. -30 in the dead of winter.
@@nicolasroberge2829 Nicolas, thanks so much for the reply and info! It means a lot to have real world feedback about something, so not just having to rely on advertising or general stats. OK, -30 (Celsius, I'm assuming) is a bit colder than it ever gets here, so I just may be looking into getting a mini split heat pump and will check out the Carrier brand.
Thank you !!! Excellent production !!!
This was fascinating!
Excellent video which explains in basic terms...Well done
Amazing explanation, thanks so very much. 👍🏻
I absolutely love this show!
Great explanation! Love that you have a small block Chevy flywheel on the post.
