    Hello! Here's a comment with some extra info on efficiency and the metering devices used in heat pumps. First: my wording on the efficiency drop in the cold was sloppy, and it sounds like I'm suggesting the need for defrosting is the only reason it loses efficiency. It is _a_ reason, but not the biggest one - that's simply that as the outdoor temperature gets colder, it's harder for the refrigerant to absorb heat because the temperature difference between it and the air gets smaller. In fact, in the clip when it was -10°, it wasn't building much frost at all because it was very dry. But that was so cold that the refrigerant could barely capture any energy, which is why its output was tepid. And to be clear, its rating down to 5° doesn't mean it operates at full efficiency at that temperature. That's just the lowest temperature that it can sustain its rated heating output. Re: metering devices. I still somewhat suspect that the mini-split has a capillary tube and largely because of its cost. It was surprisingly inexpensive (this unit was about $1000, but the smallest units from this same manufacture only cost $750 and are fully capable heat pumps). If you use a thermal expansion valve or similar, you need one for each direction which adds to the system's complexity somewhat. I'd still argue that it hardly does - it is, after all, one or two small components of a large system. But simply reversing the refrigerant flow doesn't work on its own in systems that use these more complex metering devices. They'd need some additional piping and valve work (some such valves were visible in the demo rig) to accommodate two metering devices for each direction of flow.

      @melskunk central heating is a big system where water is heated by power plant or similar building that is built specifically for it. Then this water travels via pipes to houses and goes through radiators, cooling down and heating up rooms.

    What you will notice is that in a high humidity environment, the indoor blower fan will accumulate a lot of mold which affects the balance of the indoor fan wheel. When that happens you have to remove the squirrel cage fan and clean it which is a huge PITA. So I also run a dehumidifier which keeps the mold down.

    Great video as always. You understand the refrigeration process better than most HVAC technicians. First a slight correction on the metering device in your mini split, it is most likely a Capillary tube actually but it is located in the outdoor unit. This is why that in the summer the small refrigerant line will be cool to the touch in cooling mode, not like a traditional liquid line on your AC condensed unit. That’s also why both refrigerant lines are insulated to prevent condensation damage. It sounds like the system you want is what we call a dual fuel set up. Expensive, but provides the best heating solution.

    Heat pumps have been around for a while they just suck a lot of power. One of my favorite devices, happens to be a camper fridge, the ones that run on propane or electric, ac, or dc. Basically there's no compressor, I think the freon is ammonia based, but all you have to do is just heat up this canister in the back of it. As you heat the canister in the back, it creates cold inside the fridge. That means you could literally light a wood fire behind this thing, and it'd get cold. That's how they get away with making it run on propane, the propane will heat the tank, they have a water heater type element around it, that will heat it with 120 volt AC, and they have a 12 volt element, that will also heat it with 12 volt.

    Great video brother! Quick note on 14:59 - The metering device on a MS is usually a capillary tube unless it’s more efficient and then you would have a thermal expansion valve of some kind or electronic expansion valve. However they are not located in the indoor unit they are actually located outside on most occasions.

    It sounds like you're saying that a heat pump produces a over-unity for heating. Are you saying that the power plant miles away burning natural gas is more efficient than heating with a fireplace or natural gas furnace on site. Isn't their loss in powerlines and conversion losses from burning gas to boil water to turn a turbine heck they have to pump the water to boil how much energy was used for that? A gas furnace is using a blower motor for it's electric needs but a heat pump is using that plus a compressor several sensors and electronics. Let me tell you what savings you'll have with a heat pump water heater. None. Upfront cost - High, Plumber - High, + now you need a HVAC Tech - High, It affects your homes heating system costing you more, needs a drain for condensation. It falls into regular resistance heating with heavy usage or everytime it needs service and Techs are so expensive no one gets it serviced so shame on owners for not maintaining it. It works on paper not in reality. High Maintenance costs are the problem with technology and only the rich enjoy these impractical clown engineered devices. Most improvements in vehicle fuel efficiency came from weight reduction and turbochargers. A drop of fuel will always contain the same amount of power as it did 50 years ago and probably 50 years from now.

      I can say with all honesty, if you are in a part of the state that does sometimes, even rarely, get a cold snap have a backup heat source available. My family had mini-splits in our apartment in south-central Pennsylvania. Not an area of this state known for the type of cold and snow you see along Lake Erie or towards Pittsburgh or State College. But for those few days in the winter when the temperature would start hanging out perpetually in the 20's the units did almost nothing. If the temperature got below 15 they stopped working completely. We ended up supplementing the heat with an electric fireplace that doubled as an entertainment center.

When I lived in Scotland, a local architect, who lived in Germany for a while in the 90s, was furious while telling me how British architects and builders are still building traditional looking houses with single glazing and hardly any heat insulation, and thus the occupants of these houses then have to turn up their gas heating high to stay warm. It's a good thing gas is cheap in the UK, but it won't be like that forever :/

    The Texas Big Freeze of 2020: I know of a large company that replaced their Propane based HVAC system with a heat pump system that was all electric, and guess which one failed, because Heat Pumps lose efficiency as the temperature drops? Sure, you can get add on electric elements for heat in the system, which works great, right up until either A) the power bill gets jacked up thousands of dollars, or B) the power goes out or into rolling blackouts, and regardless, you are still a slave to an electrical utility, and with the likely potential of higher bills even when working within 'normal' temps, or a blackout whenever they need it. With propane or natural gas, it's easier to run minimal systems with a backup generator of some sort. One of the owners who approved purchasing this technological trainwreck stated that they had researched it first.. on KGshows.

    As a payer of ridiculously high heating bills in Canada, this really caught my eye! So I googled it a bit... Here's what I got: For climates with moderate heating and cooling needs, heat pumps offer an energy-efficient alternative to furnaces and air conditioners. Like your refrigerator, heat pumps use electricity to move heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. (As cold as it gets here, well it gets just as hot in the summer, not very moderate) Drawbacks of air-to-air heat pumps are: regular maintenance is required (cleaning the filter on the indoor unit) and a service check every 2-3 years. loss of efficiency as temperature decreases below 6-7ºC (but some models can still provide heating in temperatures down to -15ºC) (So in Canada, where winter temps get as low as -40C, this will require either another unit, or wood heat to take up the slack.) How much will my electric bill go up with a heat pump? $50 to $100 per month. (So I guess I won't be buying one, shucks!) Heat Pumps will raise your electricity bill - but lower your costs for other heating fuels. Each single unit (often referred to as a one-to-one) heat pump that is used daily will increase your electricity bill by $50 to $100 per month.

    What a load of mumbo jumbo. It's against reason to think you could efficiently warm up your home with air that's a lot colder than the air indoors. Can't possibly work without using loads of electricity. It is most certainly not going to be more energy efficient than just burning gas onsite to fuel central heating.

    So its like a portable air conditioner which blows the hot exhaust air inside instead of out the window?

    Incredible content, as usual. It’s rare to find such production quality filled with solid engineering knowledge. Definitely one of my favorites on YT.

    We have heat pumps in the UK. I used to work for a company that installed them underground.

    In western MT I heat my 30x40 well insulated home with one of these heat pumps except for when it gets below around 5*F. I don't bother to use the air conditioning cycle in the summer as I just open the windows in the early morning and close up the home during the hot part of the day.

    Incredible, you managed to make me understand this. Wow, that is quite an accomplishment, thank you.

    Why has no one made a refrigeration system and named it "Maxwell's Daemon" ???

    "Air conditioning has been standard in American homes for over 50 years." You are showing your privilege, here, son. Make that 30 years, and you would be correct.

    ok, so does this mean when Tesla announced they put a heat pump into their Model 3 that they just added that little reverse valve and piping thingie? Because the rest was already there being the A/C system that comes as standard in basically every modern car. [edit] that's exactly what you point out in the next one, nice :) [/edit] Also the fact that this system can have an energy efficiency above 100% blew my mind.

    The “future of home heating”? Really? Heat pumps have been around for a long time.

    I had no idea I was interested in this stuff. Maybe I should go into the HVAC trade.

    Wow. First up....those split air AC systems are getting retro fitted to many buildings in U.K.....such as workplaces, dentists, doctors surgeries. As for heat pumps, the aim of U.K. gov is to have all new buildings + replacement systems be heat pumps (or alt simply electric heating) in 10y from now. Currently most buildings are heated by gas - not the stuff you put in automobiles, but the gas they dig up from under the sea and pipe it to buildings. Are heat pumps really that reliable...seems to be lots of plumbing in the system.

    Heat pumps have become a relatively commonplace method of heating homes in New Zealand.

    quick question, can we use electrolysis to build pressure without an electric motor? doesn't have to be electrolysis, all it has to do is be less energy intensive than running the compressor and cause out gassing.

    In the Netherlands we have homes running sololey on heat pumps, no gas or electric backup. We use water-to-water heat pumps with heat recovery and (efficient) low temperature floorheating. Since ground water doesn't change too much over time; the heatpump is very effective all year through. Installation costs are pretty high; but to be connected to gas, you have to pay a monthly fee. Also; you're only using electricity and when combined with solar panels (and triple isolation); we can create practically '0 emission'. It really helps that the Netherlands doesn't have extremely harsh weather though, but water/water heatpumps will be much more effective in the US. Looking forward to part 2!

    Soooooo, then the most efficient system would be to connect your gas burner to a small steam turbine, all kept inside so you don't waste heat, that produces electricity to run a heat pump XD

    What if someone made a heat pump that had something inside the house insulated with a high thermal mass that could be used to store heat. So when the heat pump is working at peak efficiency, it could store thermal energy for later.
