How Do Heat Pumps Work? | Heat Pumps Explained 

Short, simple, packed with info which can be easily absorbed… DEFINITELY the best video on this topic on the entire platform. Thank you

GREAT video! Very client-facing friendly, easy and simple to understand, SHORT, and your intonation, enthusiasm, and the animations hold full attention. Thank you so much!

Simplest video thanks

There are three or four other videos out there on this subject, but this is the best. Well done.

winner, informative, no filler -- thank you for great content

I've always known heat pumps to be crap. The reversing valves were always problematic.... ty

thanks dave - really helpful.

Outside when cold contains a certain amount of heat? I see a lot of people confused about this. They're using a more formal definition of heat here, which is a transfer of energy. Unless something is absolute 0 degrees (-270c) it contains a certain amount of energy. By using the ~cool~ relationship between pressure and temperature, we can cool down a fluid to below the outside temperature and gain some of that energy. Or, get heat from it. Then reverse that process and end up with a higher temperature than we started from because we took energy from the outside. Talk to a qualified supplier if you're worried about it being too cold in your neck of the woods.

Thanks so much!

Nice explanation short and understandable.

Thank you so much

Great explanation in a quick and easy-to-understand way. Well done.

Thank you

Thank you bro

It's minus 30 here today lol. No way this is heating my entire house. Manitoba is so cold man.

very nice video!

Nicely explained...

need more of these amazingly easy to understand videos

Is there only one vent indoors? How does it affect other rooms at the other end of the house. If my bedroom is 80 F. and the heat pump vent is in the front of my house, how does the bedroom get cooled in the summer? Also what happens if we have two floors? Do we need a separate unit for each floor? Reason I ask is because my old fashioned window AC unit doesn't do much for other rooms.

How you gonna install these on terraced houses?

More efficient than oil central heating?

In the winter it "pulls heat from the outside air " into your home. In Ontario at -30, what heat?

That's fucking sick, great animation too, thanks!

How much heat do you get out of minus25 to minus 30 c degrees?

what if you already have gas, how are you saving money...especially when the temps drop to -20c and colder....

How much power do they use? Would the heating cost more than gas forced air heating?

But don't get rid of you woodburner.

My question is can the heat pump be installed within the house to capture heat at 60 degrees, instead of outside ,where the efficiency drops with temps below 20 degrees, It could still be vented with a louver.

Misleading Ad. Size 18 to size 2

@BC Hydro So If I have a heat pump and i turn the heat on... am I circulating fresh air from outside into my place along with the heat thats being pumped into my home? And if its the ac only sucks air out of the house... no fresh air is being circulated inside right? Im asking because i've had to seal off every single vent door and window in my place because of 24/7 nasty smelling skunk smoking neighbors and want to know when i turn on the heat is that a way that fresh air gets into my place without having to open the windows?

Can Heat Pump be used in a apartment?

👍👍👍☕☕

I do not think this set up would work for a lot of Canadian homes. And it’s only for one room. Most insurance companies in Canada would not allow that as a primary heat source. I could be wrong ……. If I am get back to me.

They say heat pumps don't generate heat, but then explain how they use a compressor to raise the temperature. Maybe we have different definitions of "generate" here

notice he said it's not cheaper than a normal gas boiler. ps. Why do people say it is hard and only works with underground pipes instead of just the vertical ones.

So heat pumps only reduce carbon not eliminate them?

it heats the top half of each room, cool.

Isn’t this just a regular double function AC that has been used in Asia for like 30 years…?

One thing to always remember, there really isn’t such a thing as cold, it is just lack of heat.

Dave! There are heat pumps with COPs up to 5 not just 3! Even more savings of $$ and CO2.

I would say this is only useful in temperate climates. I'll stick with a gas boiler.

People in us called split ac heat pump!! Why is that.

Now with a hole in your wall cold air gets into your house in winter if you do not turn on heater.

Don't think very cost effective with the unit at the ceiling. Most heating systems are at the floor. Remember heat rises.

But it costs a lot in electricity to run that pump

BC Hydro is completely Vancouver/Victoria centric. So many people who have installed heat pumps here in NE BC need to run secondary heat when it gets cold during a time we call...winter. Nobody except greenie Vancouver transplants install the few units that do get sold here.

Glorified dehumidifier

BC Hydro pushing systems that run on electricity instead of natural gas, is like KFC advertising that beef is bad for you.

its amazing how he compares it to electric heating.........LOL compare it to natural gas heating or even oil

yeah so how the effects of refrigerant on the atmosphere??

Hi BC Hydro, we are thinking about installing a heat pump and an HVAC tech mentioned to us that the inverter runs no less than 20% power. So let's say for example.. I have a 36000 outdoor unit running to a 12, 18 and 9 unit inside our home. So for today, the only unit that is on inside the home is the 9 in the bedroom for Granda. Once the 9 unit reaches the set temperature it will then dial back the inverter outside to slow down.. but since the inverter can't run less than 20% of 36k or 7200 BTU worth of energy, then the 9 upstairs will never be able to dial back the inverter outside lower than generating less than 7200 BTU worth of power consumed. Now, if the 9 in the bedroom is independent and running on a 9 outside, then the inverter at 20% would equal 1800 BTU when the 9 is it's running the inverter at the minimal 20%. I'm not sure if this math is correct or not or if it’s true that the inverter runs no less than 20% power? Maybe you can make a video on this subject... I want to make a decision on whether to buy one outside 36unit or go with multiple units such as a 12 & 9 &18..

But it cost more in electricity natural gas is cheaper and way better at heating

Do heat pumps blow dust around like a traditional furnace?

OMG The heat pump does create HEAT... How when you compress a gas YOu create HEAT... Use that heat to heat the home then dump the energy by decompressing and allow the liquified gas now vaporize... By expelling it outside the COLD you do not want. The new new gas free of energy can be Re compressed. To chill a home in summer we compress the gas and dump the heat OUT SIDE. then the liquefied gas that is cooled get decompressed and gets supper cold that cold liquid now sucks the heat in the home.... The gas is now deenergized and back to normal gas. Goes back to the compressor to compress the gas again. Formula for Creating heat when compressing gas. Boyle's Law: PV = k.

Natural gas dosent tie your indoor temperature to an electrical grid. There by reducing your effect to climate change temperature regulations by the government in the future.

People, please do some actual research into this before you make the decision of buying one or two or three. Heat pumps work best between 10*C and 30*C; once you start nearing 3*C they become less and less efficient. Once you surpass -6*C they become pretty much useless and you need to start using supplemental heating ie: space heaters throughout your home. Not to mention, the heat pumps themselves start to ice up and have to run their own defrost cycle to clear the ice away from its metal fins and then start working again. There are a couple of heat pumps out there which can operate to as low as -15*C (still not at all close to the -30*C temperature we just saw) but even these can only provide enough heat for up to about 400 to 600 square feet of living space. So are heat pumps more efficient and carbon neutral, yes, but only between 10*C and 30*C. The other consideration is that generally heat pumps, like the video shows, has a wall mounted unit which is in only one room of your house therefore, you would need separate units in several rooms of your house with refrigerant lines running all over the place to the outside. There are heat pumps which can be retrofitted to work in a ducted house which previously had a natural gas furnace however, these are less efficient and require a large amount of retrofitting to be able to move enough volume of air. Ducts are the size they are because of pressure and the volume of air you needed to move through them based on the location of your furnace and the size of the home being heated. So, to retrofit this design with a different system which it wasn't initially intended for isn't simple and costs more money and additional electric fans are needed to move the air through the duct system. I know the Federal Government is pushing for heat pumps and willing to give a rebate for them but they just don't work entirely in our climate in Canada and yes, I know Vancouver and area doesn't get as cold but even around 0*C the heat pump is working near its capable limit which isn't easy on the unit to run at all winter long. That would be like driving your car around in first gear everywhere. Can your car do it, yes, but it isn't designed to maintain this situation for long periods of time. I like the thought of being more carbon neutral but heat pumps aren't for our Canadian climates.

Good video, but that mandatory Stupid happy music I can do without

I moved from BC to AB and I miss my lower bills.

Why not to have an heat pump this is from the BRE to explain why EPCs downgrade if you have them fitted “the reason that the heat demand may increase with a heat pump compared to an oil boiler, is that heat pumps … may need to be run for longer hours to give sufficient heat output over a 24 hour period and to avoid very long warm up times. Running longer hours…. would result in higher mean internal temperature. Consequently, the total heat losses would be higher, so the energy requirement would be higher” 4

"It's an environmentally friendly option *especially* here in BC where we're powered by water". This statement is illogical. The difference in environmental impact would be *greater* in places where they use *less* environmentally friendly power sources. So in BC where we use *more* environmentally friendly power sources the saving to the environment would be *smaller*.

Sorry I'm sticking with gas for heating and cooking and an ice car for driving. I'll wait until all the bugs are sorted out before I'll consider

Someone told me they are crap and dont work properly a waste of money they say.

"Upcoming Refrigerant Changes: How the R-454B (Puron Advance) Transition Affects You To satisfy industry regulations, the HVAC industry is transitioning from Puron (R-410A) refrigerant to Puron Advance (R-454B) by the year 2023. We talk about the implications for homeowners." -- It's SOOO great when you all decide to just copy and paste talking point with zero understanding of how anything works. 🙄🙄🙄🙄.... so, you're gonna fix global warming by going from one pollutant to another, right? Wow. Just, wow.

In winter, even before reaching 32F, they barely work. When it comes to providing much needed warm, they are like a kid shoe compared to 11-sized boots, the fossil fueled heaters.

Confusing af

Suck the heat from outside.. the weather has been unseasonably cold, this year and last, right up to the middle of June. I see a connection.

If you live in L.A, they're great. Anywhere else, they're useless.

just remember this: you are the carbon they want to eliminate. simply put; heat pump is the same as a window fitted air conditioning unit. compressing or evaporating refrigerant to heat or cool a coil. one side blows cool air, the other warm air depending on which way the refrigerant is flowing.. heat pump same concept.

Cold showers, no thanks

Why is very cold air getting blown over the coil why is it not enclosed recirculate the heat in winter it won’t catch fire explain that to me on the Shetland Isle there are no trees to hug so sad it is

Soooooo going to electric instead of what you call fossil fuels is a comparison with shoe size how abouts you show us some actual data. Let’s see some actual numbers here.

good video but he is kinda annoying but not too much

I see so if its -25 outside the coolant warms the air up to 5 degrees making it warmer than outside?...with a good collection of wool sweaters and gloves along with a good down jacket you've got it MAiD! Even the Eskimos can get their Igloos to about 1 degree inside away from the biting -40 weather...if Canadians would just use Igloos like Guilbault and Trudeau would like we could get to Net Zero in no time like the Eskimos then we would save the planet with renewable energy....and we could easily handle any harsh Canadian Winter! However, I don't think our $12k/month Grocery Bill Prime Minister would adopt that kind of lifestyle that's just for the folks who will own nothing, eat crickets, and be happy!

you forgot to say how they cannot appropriately heat the domestic water supply and require an immersion "hidden" in the LARGE water tank to compensate? massively increasing electricity bills and that the heat pump increases electricity usage annually by anywhere between 20% and 45% (depending upon the annual climate of homes location)? or that they are next to useless on any property built before 1930's due to wall construction?

Not to mention if the power goes out your screwed.

Could they find a more annoying person to do this ad?

This is a crap idea that's just gonna make electricity more expensive and give you lower performance and reliability.

This is a brief description of what a heat pump does. There's no explanation of how it actually work whatsoever.

Looks hideous and it looks like someone could easily nick it from the wall.

And they are as noisy as heck, can you imagine when everyone on the block has them running! With all these electric heatpumps and EV this will put another strain on the electrical grid...heat pumps are not the answer.

Another thing mighty reliant on daddy government ensuring the electricity continues to flow.

Americans are like, "Let's bring back coal!". Canadians are like, "We're gonna pull heat from the air!"

Why don't you ask that volcano going off in La Palma for 1.5 months now to to back off on it's carbon footprint?

Heat pump can save your electric bill ❤

Excellent propaganda!

is it run on electricity?? and if so how much does it cost?? to run does the cost of running it outweigh the alleged benefits?

Heat pumps are shite.

the heat produced by these is very poor, noisy things that lose efficiency within a few years{ not even that efficient from new} trying to sell the electric dream .

You lost me at "fossil fuels" and "carbon footprint" The only thing you missed were the polar ice caps melting.

So full of BS!!! =)))

Bull, talking crap.

I knew these things were b***s***! ‘Even when the air is cold, it’s still hot!’ WTF😂 Basically they are weak heaters that are more energy efficient because they don’t provide much heat😂

No Thay are way more expensive how can you make clams like this gas is way cheaper do some research bro.

Heat pumps are junk. Heating cost are too high.

So the liberals expect people to heat the whole house with this. I guess he doesn’t know how cold it gets In the winter months.

Are left to rot !!!!! Another business scam

it is scam

They are a scam 😂

Not worth bying

Of course BC hydro wants you to change over to these pieces of crap, sell more energy. These heat pumps require energy and run, almost 24/7 to keep your house at a desired temperature, yes they will cycle but in most of the northern parts of the provinces they will in the winter never keep up. Oh the bs is out there that at -25 they are good, in an experimental house that is mocked up with the best windows, doors, over insulated walls and attic. You will still need back up heat of some sort, let me guess BC hydro…..electric baseboard heaters. CLOWNS.
