Do you think we need to heat pump all the things? Go to https://curiositystream.com/Undecided to get Curiosity Stream for only $14.99 for the whole year!

1 joule = 1 watt-second. So it is using 1 watt-second to move 3-5 joules of heat? So equivalently you're saying it uses 1 Joule to move 3-5 joules of heat? I think it's important to differentiate the difference between units of power vs units of energy, because if you use 1 watt of power over 0.5 seconds you've only used 0.5 joules or .5 watt-seconds of energy or if you use 2 watts of power over 0.5 seconds you've used 1 joule of energy or 1 watt-second. E = P x t [Energy = Power x time].
Heat pumps are ingenious inventions.
Have you looked at water hammers, I watched a video about 8 years ago, I don't know if it is still on YT! Might be worth looking into!
a few numbers and facts of your presentation is off, now i'm going to assume ignorance for this.
the COP for an Air to Air heat pump is 2-3.5 not 3-4 and those numbers are assuming absolute perfect conditions. If you live in conditions where the temp is too low you're just running electric heat which will give you a COP of 1. It is true though that ground heat pumps are a higher efficiency and that's by company standards around 3.6-5 however that's once again assuming your house is well built for heat pumps and that their insulation and draft free.
a high Efficiency Furnace is 95% not 85% 85% is considered a standard efficiency of a Gas or oil furnace the higher efficiency is achieved by adding in a secondary heat exchange that pulls more heat from the flame produced it's so efficient that you have to have condensate drains to pull out the water from the heat exchanger since it cools it down and these have a COP of 1.5-2.8
most of these "Energy Saving statistics" assumes the house is also retrofitted for the perfect conditions to include insulation and draft proofing. It's like saying "An EV saves you more money when you drive." while ignoring that the tests done were on perfectly paved roads going at residential speeds.
electric backup comes standard, since even during normal operations the heat pump can still frost over if left running long enough.
The water heating heat pumps use electric heaters to make up the difference during high demand periods of heating and cooling.
I missed this point earlier it's not a "Fluid" it's a refrigerant since a heat pump is just a standard AC unit with a reversing valve that allows the flow of the refrigerant to use either coil to heat or cool the space and it's R410A that's the most common type of refrigerant but you can also find them in R22, and R134A.
Lastly is servicing costs which are never considered when it comes to overall costs of the unit replacing any part on a heat pump is not cheap and can and will break down over time, for example lowballing a reversing valve replacement which includes parts you might need to replace with it (Filter drier, TXV, solenoid.) you'd be looking at around 1000 in parts alone and that's if you order the parts from the manufacturer and DIY which federal law frowns upon since you need an EPA certification to work on the refrigeration lineset.
i bought one of the dryers in Australia $1400aud , it is so much better all the water is drained directly to sink or into a water draw that you empty by hand (very simple quick and easy), i like it better because it doesnt pump warm humid air into the room (less mold) and its 7 star energy rated
The old way to dry clothes uses no energy at all, line drying. It takes more space and more labor but not much. In parts of the US, it is considered a faux pas to display your laundry on your property, and this stigma is highly dysfunctional. We should get over it.
depending on where you live, be careful about the extreme winter costs. Seems great on paper until you get the shocking $800 bill in December.
Heat pump the world, for me the ventless ac, heat and dehumidifier all in one was clutch for and addition to the house we bought that didn’t have ac and 2 natural gas sources to heat it
Nope heatpumps are garabge
Know what's even more efficient than a heat pump clothes dryer? A clothesline. If you're serious about saving energy/money/the earth, use less technology, not more.
My question for the heat pump dryers: won't the condenser and evaporator get clogged quite quickly with lint?
I really love your work, Matt! Keep producing content and know you're an inspiration!
I have heat pumps on 2 of my properties with solar and batteries and I've almost never paid an electricity bill… I mostly get $150 back from the grid each month in Brisbane, Australia
Really looking forward to your videos on the new house build. Hope it encourages people to adopt your ideas.
Skinny pipes (just make them parallel) that are treated to be Super Hydrophilic will pump/flow/circulate water with no energy needed!
And combine this system with an aircrete dome home, even more savings!
There is a new technology on the horizon called magnetic refrigeration. This technology uses a magnetic field to create temperature differences. It offers a higher level of efficiency over a compressed gas system. It has the potential to operate at lower temperatures because it does not involve a gas.
If air conditioner and heat pumps can move more heat than they use, why don't we have "perpetual energy device"¿
Electrical that are made from coal , gas, oil . What are u really saving
Heat pumps really well suited to coastal areas. If you have ever used heat pump in cold weather, especially in cheap built / poorly insulated housing, you learn gas is much much much cheaper and more capable heating in winter. So a COP of 5 is still cost wise worse than 75% efficient gas furnace bc cost of energy is less. The device must work harder if outside temp goes down. When it was -15 at night we had to set apt to 80 deg F the day time to get ahead bc the heat pump couldnt keep up. Our heating cost was like $200 usd that month, gas bill wouldve been like 100
Producing carbon dioxide isn't a problem. AGW is false. We actually need more CO2. We are in a Co2 low.
I am always bewildered by people that think about CO2 emissions, as if this were a thing. Just work with whatever is cheaper to achieve the goal. For many people, that used to be natural gas, until some criminal politicians decided to make it expensive, so that other high maintenance tech start to seem economically viable. But still, most people on earth use wood to heat and cook. Wood is ecological. When burned, it grows more wood. Perfect closed loop.
Everyone I know, using heat pumps, say they regret it, because they are not doing their job. The shower water is just warm, not hot. The house stays colder than wanted in winters. And we are talking parallel 45, not the Arctic. Maybe the tech will improve. But the costs are not worth it. Stay on crude. Burn CO2, be reasonable.
We had a geothermal system in my old house. While it is 20 years old and that may have contributed to this, but it was very slow to heat and cool the house. Although if you keep it constant it shouldn't be an issue. (We also had a very large house)
Not only are heatpumps expensive up front, they cost a LOT more to run compared to gas over here in the UK. At least at the moment.
I like the idea, but it's not economically viable atm.
We are looking into a solar heat pump. I think you need about 6 to 8 panels and bats.
As with many new technologies upfront costs are higher abd therefore even where the running costs are lower the payback time is sometimes far too long. When confronted with this kind of trade off most of us would conclude that continuing with the conventional methods of heating/cooling makes mores sense. So I feel you need to point out that real cost/impact of many current systems on the environment in the hope that some viewers would take that into account when considering replacing there current – usually fossil fuel enabled- systems. It is because the environmental impact of so much of our fossil based energy consumption costs “nothing” that we are in the current mess!
you go girl
I just got the plans approved to renovate two apartments, plus I'm doing an ADU in my basement. This info couldn't come at a better time. This, plus finding out that Tesla Powerwalls are much higher capacity than when I last looked (7 kwh before 13+ kwh now) makes me really excited for how much good I can do with these projects. Now I just wish it was a little easier to put solar into multifamily buildings.
