  • Hey everyone, it’s pinned comment time! And there are some *corrections and clarifications* here. Exciting! First, heat pumps part 1: Second, refrigerants! Sloppy script-writing me didn’t catch that I implied CO2 as a refrigerant was the _only_ other option, but it’s not! There have been many climate-friendly refrigerants in use in lots of applications such as isobutane and propane, but the main trouble with these is they go boom sometimes. In larger systems the quantities needed can be dangerous which is why R-1234yf and CO2 as refrigerants are important! Third, heat pump dryers! My explanation into them is, um, well not right. It’s better to think of them as giant dehumidifiers that recirculate air through the drum. Heat slowly builds up, but it’s not really being taken from the room. Instead it’s just the heat created by the compressor being continually recaptured, and a sort of thermal feedback loop forms. The cold surface of the evaporator also pulls the moisture out to be collected. Here’s a video from This Old House that has a great diagram (though the refrigeration cycle’s magicalness of latent heat is pretty much skipped) Fourth, I regret saying it's a "myth" that tankless heaters provide instant hot water. More fairly I think it's a misconception. Fifth, I dunno! I’ll add stuff here as we go along. Aren’t pinned comments neat? I love being able to put information right up at the very top for you so you don’t have to waste your time commenting!

  • Our water heater is a hybrid one. We run it on heat pump most of the time. And because it's in the garage, it actually makes a great air conditioner for the garage in the summer. Especially since our garage door is insulated. I can actually just use my garage as if it's another part of the house. However, in the winter it gets hella cold in there.

  • Here in French Canada, A/C is almost a foreign concept and our electricity is stupidly cheap and green. Electric heaters make sense here. I say almost, because one half of my building has A/C and my half doesn't. Where did they stick the heat pumps? RIGHT ON TOP OF MY SIDE OF THE BUILDING. There's an extra-loud one atop of my very dorm. Thanks to acoustic bullshit, it is especially noticeable when I'm in bed or at my workstation. I am not fond of heat pumps. I don't care if it's better. I don't care if I could save the planet. Heat pumps are loud boxes over my head and the less I have to hear them, the better.

Well, everyone knows the downside here. People will freak out about propane in a refrigeration system, and yet no one has a problem with 600 gallons of it sitting in a tank behind the house. What about cars, you say? Ok, well, I guess the 10-40 gallon tank of HIGHLY flammable liquid sitting underneath your vehicle is also a problem.

  • My parents added a geothermal heat pump to their house when they built it around '99. They /could/ have taken a vertical system, but since they had the place and were digging around anyway they chose the horizontal system. Unlike in your examples this isn't used for eating the air of the building, but solely for the central heating for both the warm water and the house's floor heating (we only have floor heating). Thus it isn't as easily reversible, but it *does* keep the house cooler in the summer a bit. The system runs without much problems and only around two years ago or so my parents had to replace the pump due to age. 😁 Fun fact: back then our friends had all said that they'd come around with blankets and such when our heating would fail, cause it wasn't that known back then either, but we always had a cozy home with around 23°C 😍 I take it condenser dryers aren't that common in the US then? 🤔

  • Rock isn't that thermally conductive. Thermal Coils will shed temperature certainly. But when the cooling side becomes saturated, the rock will start to struggle to warm up fast enough by soaking heat from nearby rock or soil. But A surface mounted system can dump heat into a subterrainian solution. And you can pretty much dump as much heat down there as you want. It won't STAY but it will at least absorb more heat than any heat pump can dump.

  • Hey, *I've been watching your videos for a while now* As an HVAC Tech who does Electronics for a hobby (including repairing VCR's back in the day) I appreciate how accurate your videos are. Even for the refrigeration content whereas most techie people have no idea. Anyway, *as it pertains to this video* I thought maybe you would get a kick out of a few of my own projects. I installed a 3 ton 3 phase condenser onto my home for a Solar Powered project (that is still ongoing work). I get the 3 phase from a Variable Speed Drive. Single Phase in. DC in from Solar. *I converted the straight cool condenser into a heat pump* here where I added a reversing valve, Thermal Expansion Valve, etc. Check it out! And as for my water heater. Well right after I replaced it I installed a HEAT PUMP with a circulation pump to heat my water. I later installed a smaller heat pump. Entirely DIY with a compressor, evaporator coil I fashioned, and a heat exchanger etc. I'm using a 9,000 BTU compressor. Pulls 8 amps at 115V which is about 4 amps at 230V equivalent. In compare to my 4.5KW heating element that draws 18 amps at 230V, that is a bit less! And it doesn't take too terribly long to heat. My most recent DIY heat pump is mounted outside and I ran the water pipe through the wall. I have yet to install a frost sensor so it did freeze the coil TWICE this winter. (It's pretty mild here in the AZ Desert) The videos are cool. I'm 50 yrs old so some of the old tech you review are fond memories!

Moving heat via a heat pump can be very efficient under certain conditions / parameters, as all your doing is moving heat not generating heat, this falls in a narrow band of efficiency after which generating heat is cheaper than moving heat

It turns out a lot of waste heat is not actually otherwise wasted heat, but a deliberate effort to create a lot of heat by making processes less efficient, or at least control the efficiency of some industrial process. Often this is because of political reasons.

  • The people I know that hate their heat pumps, hate them because of the cost. The high range of COP for most middle-market air sourced heat pumps (the ones a consumer would most likely own) is about 4.0, which is just about break even cost-wise compared to natural gas. So for most consumer-grade heat pumps, they are as cost efficient as gas at the best of times(actually when you WON'T need heat) , and usually worse (usually during the times you do need heat), - and if they turn on their resistive heating backup source, they are 4 TIMES more costly to run. You can add a Natural Gas Backup source, which would mitigate much of this, but in my experience, that's not how these were typically installed.

  • While your points are accurate and informative, and energy efficiency is important, I feel like you are blowing way over the problem of initial cost. Even the examples you provide from Lowes and HD are 3x the price of traditional methods. For many people that live in existing homes, a new water heater, dryer, or AC system is a sudden and often unplanned expense that can be difficult to afford the cheapest option available today. To require everyone in every climate zone to pay 3x more for a better technology doesn't always make sense. What if you live in the south and use solar to supplement a cheap resistive water heater? All I'm saying is initial cost and green funding have to come from somewhere, and it's not as simple as regulating everything to the most expensive option.

  • Going more effcient does not always pay. One consideration of heating and cooling is that there are times, it just does not pay to go more effcient. Ran the numbers recently on a small house in the south (TN) and heating and cooling energy averaged about $1 a day. If you simply take some care on appropriately selecting a unit, and upgrade the unit as needed (every 20 years or so) the gains from being super effcient are just not worth it. Sure, one needs to make sure your home is appropriately insulated, and weather sealed. There are plenty of things you can do that can limit heating and cooling needs (plant shade trees in the right place, maximize solar gain in the winter, ect.). But the cost of the unit and the installation of the unit is a major problem. Having standardized units that are easy to service and having educated people are also major problems. I mean, we struggle to get people to change furnace air filters every 30 days. With costs of $1 a day, what if I saved half with a more effcient unit. (aka $150 a year, how much would that be after 10 years? $1,500 That is not enough money to buy fancy equipment. Even with a 20 year life it is hard. A basic economy whole house heat pump costs $2,500. Brand names which are high quality last longer and cost a lot more.

    • The cost consideration discussion really needs to include several things. (Energy Costs, Equipments Costs, and Installation/service costs). Let's say a lower end HVAC heat pump unit costs $3,500 and lasts ten years. That means each year you "use up" $350 of equipment or about $1 a day. Having that unit installed is also going to cost, say $1,800 (That is $0.50 a day in installation costs). You should have the unit checked annually. That may cost $150. (Aka $0.50 a day). So over the life of the unit your costs are $1 a day for energy, $1 a day for equipment and $1 a day for installation and service. (Notice how i am keeping my math easy and simple.) While buying a more expensive and higher quality unit does result in longer life and potentially less servicing, the benefits are highly risky down the road. You are making a substantial bet that the unit will function without a problem and your benefits will be extracted at the end of the life of the unit.

  • Hey, great video, as always. And thanks for giving the temperature in Celsius as well, but could you consider giving pressures in bars/atmospheres or hPa as well? Feet I can convert myself, but temperatures and pressures are more complicated :P

  • Or if you want instant hot water you could go for city grid heating.

  • April 1st. Oh I get the joke. It's something that let's you be as off grid as possible and yet it's advertised with its "low emissions".

  • When I was in this small crappy apartment I had one of those crappy portable air conditioners. It didn't work great for cooling, but was awesome at drying clothes. They should have marketed it as a clothes dryer (who has an AC vent into the indoor space--isn't that just a dehumidifier?).
