While induction is in theory better, there are issues! 1/ magnet size does not always match graphic outline of the stovetop, so (say) the inner part of your pot or pan is hot while the outer part is not so much. This makes for terrible cooking. More expensive induction stoves are better in this regard. Also 2/ Induction's very fast response can warp your pans - this is bad. Not so much as issue for pots as the higher sides tend to prevent this, but really annoying to wreck your high end stainless or carbon steel pans with an overly aggressive change in temp!

Would this work with a ground source heat pump?

can heat pumps work on solar systems?

I hope they manufacture in the USA because once it goes to China the software will somehow end up there and competition galore will spring up out of thin air overnight.

I've had a heat pump water heater for about four years and has worked perfect

So, uh, what are the different working fluids? I know high temperature heat exchangers can run some nasty stuff as a working fluid (I've heard of mercury/Hg based systems).

Are there any hard numbers of cost of unit, cost of installation, savings over time, etc to compare apples to apples against current gen 1-stage heat pumps? I'm sure new tech is going to be more expensive, but if it's more efficient, wouldn't it also pay itself off at a higher rate, and as such potentially have the same payoff length of time?

Been an air-conditioning for 30 years heat pumps sound good to own one. unless you live in a house that is energy neutral you’re in for a wicked surprise. Just like anything of course you can find something top-of-the-line That does what he’s talking about but that’s one out of 1000 types of all the other 999 go look at their efficiency rating in heat. I swapped out my gas furnace for a heat pump with no solar and yeah, I don’t spend any money on gas but that $600 a/c bill I would get in the summer turned in to a $900 heating bill because it loses all of its efficiency when heating. yeah I could’ve spent 5-10 times as much (at cost cause I’m in the trade) upfront and ended up with a much smaller bill every month but the end results going to be the same because of all the upfront cost. Anybody NorCal want 2022 5 ton heat pump package unit I’ll make you a hell of a deal! Only used one season…

I have solor toom 5 months for the city to get everything hooked up night mare

I am in California and in my new house the builder has installed a heat-pump water heater. Apparently California has changed code and tankless heaters are no more allowed - at least in Sacramento county. I hope it will perform better and help me save electricity. :)

Wow you have to apply for consent to have Solar installed? Yikes! here you only have to have consent if it literally changes your roofing material, i.e. swapping from clay tiles to tesla solar tiles etc. Simply putting a panel on existing roof is just BAU house stuff and easy to do. Poor America "Land of the free-but-not-really" =) But hey your country gets better tech sooner than we do, despite us Kiwis seeing the morning sun 11 hours before you =P

The way you're describing it. I believe is incorrect. Cascading systems use the evaporator as a condenser and a condenser as an evaporator depended on the freon. That's inside, and if you're going up or down, you're not using multiple pumps to keep the same fluid pumping up. You're doing is bringing on a second compressor the takeover for the first one? But because it has that loop of hot air or cold air in the condenser oil. Evaporator the other one like a tube and a tube uses that, as it's medium instead of the air outside. Therefore, you can get the heat from the coil tubing tube. And not the air

It's very simple problem to fix. Insulate the damn houses. Because no matter how good your heat pump is, if ducked, work is gonna leak. And your building is gonna leak because you have old buildings. Phone Spray Block. Then put some stud over it, and you won't have this problem

We use cascading systems for negative 80 Celsius. Freezes and negative 20 Celsius. It's the same principle we just taken multiple little compressors with different freons with different glide and boiling points. I'm just staging them and using the medium. From the fluid as its transfer, instead of the air outside

Matt: "...the U.S. has to do way better." (on cutting red tape that costs us $ for solar) Why? It's not bureaucratic incompetence alone. It's politics, e.g., anti-Chinese import tariffs, corruption. Just boycott the govt. laws/regs and exercise your rights! Oh, wait, I forgot, NOBODY lives in a nation that protects rights. The majority get the govt. they put up with and the minority (me) get screwed, dragged down with them. I am not guilty of "willful blindness", i.e., pretending I am free, and thus defending authoritarianism. Rights are NOT conditional or dangerous. They are essential to our life, liberty, property, happiness. Don't settle for the false "choice" of the lessor of tyrants, e.g., boycott voting. Reject all of them, self-govern with others locally, in peace, voluntarily.

LG has recently launched a new heat pump dryer (model DLHC5502B). This is a 7.8 cu. ft sized one and is capable of drying a king size comforter. :)

Would a heat pump be an effective solution in Texas?

With the exception of gasoline/petrol, I think people in the U.S. pay more than most other countries for pretty much everything, so this is no surprise. As for your location (mine as well), there's a reason it's informally called Taxachusetts. And don't get me started on Eversource and what Mass DPU allows them to do.

Unless the heat pumps at either end of the spectrum are extremely, extremely efficient, I don’t see this keeping up with demand. Each heat pump can only take and condense the heat of the ones before it, so each heat pump in the chain would be running under max capacity, no? At the end, you’d get super hot air but not nearly as much as you would with a single heat pump under normal conditions, or a standard furnace output. If plus, not talking about cooling, but purely in terms of heating it’s still really efficient to use gas burning furnaces. How do these compare to those?

You can't use an induction cooktop if you have a pacemaker. But otherwise they are a good idea.

Im not so sure on the health stuff but we switched from gas to induction and love it! It’s way faster and safer. Make sure you buy high quality pots though with very flat bottoms to make the most contact with the surface. Otherwise heating does take awhile.

I would wait until 2025 when I could use my Tesla (new, improved) battery for energy storage. Also, I would have an all-electric house. Energy storage should take priority, next, energy use, and last, energy production. Calculate all the combos to find the best.

I would think with 2 working fluids the indoor fluid would be working at a temperature that would be fine but you would want seasonal outdoor working fluids depending on the outdoor temperature or even Just parallel fluids in the same or parallel systems. You would also want to isolate the fluid from the temperatures you don't want it to see. Unless you're doing something with more temperature outputs and ranges like refrigeration and heating at multiple teperatures.

Added complxity will be too costly. More compressors, tx valves, reversing valves equal more parts to replace. Not to mention corporations make things cheaper and more brittle every year. I do this for a living, good luck.

It’s basically a twin turbo!

If I'm heating my home. The first loop will transfer a certain amount of energy to the second loop. Surely, while the temp can be increased by loop 2, the total heat energy remains the same, namely that delivered by loop 1?

If it is a great product, it does not need subsidies. I am tired of hearing about how great all this tech is but it always comes with tax breaks.

i have one inside my front pocket

The fungus is among us...

I watch this from germany and habe to listem to a weird AI or AI like dubious german "translation" that fails to make enough sense to go on watching this. Please, whatever function that is swotch it off or at least make it optional for a viewer. I can't bear to proceed watching this video like that so I won't.

I don’t get it. All heat pumps have a COP around 3-5.

But how does all of this compare to microwave? And it would it be possible or desirable to heat your house and yourself using microwaves ?

Ground sourced heat pumps are better. The ground a few meters down is a relatively consistent temperature way above freezing. This is much better for heat pumps and works fine in winter.

I’d love for you to cover more technologies designed for tropical climates

Instillation costs ... $$$ ... peace of mind that you are helping reduce global warming: PRICELESS

I'll add to the "Rich person's problem" comment. I built my array over time, I started with 5 panels, I'm up to 14 panels for a capacity of 6.9kWatt/hrs of panels over 2 years. I sourced from SanTan Solar. You don't have to be wealthy if you plan out your system and build it as you can afford to.

Why Taj-Ma-Haul has a HUGE battery... I can make it through at least 4 full days without compromising my normal consumption... 4 days of 0 light... Like Matt said, even on a completely rainy day, I get enough solar production to replace most of my daily use. I have an ICE generator that hasn't been used since upgrading my battery capacity... I plan on charging my future CyberTruck from Taj-Ma-Haul... Complete and utter energy self-sufficiency.

I mean my thoughts were yeah you got scammed... No solar is not a scam.... You just got scammed .

The incentives are probably the reason why the costs are so high. Just like with college, if the purchaser can get "free" government money (that was taken from you in the first place) on something, that means the market can handle a higher cost, until the price once again hits the equilibrium point where the customer is again paying the same cost as they would without government involvement.

Compressors are the most expensive part of a heat-pump. Having multiples of them would greatly increase the cost, points of failure and maintenance.

tankless water heater analogy - very cold water comes in through the inlet - the heat exchanger can only raise the temperature so much Unless you have a very large exchanger ..so if you had a second tankless water heater connected to the first now this one can take the warmer water and heat it even more...learned this working in the bush camps we would take creek water and pump it through a water heater could only get the water warm depending on the temperature of the creek water never had a hot shower just warm..

Interesting I hope they get certified just for the sheer fact that the owner seems so personable. I have tried to reach out to Bosch and they refuse to talk to me to give me information, they direct me to a “local” provider 6 hours away.

This is not really impressive, the Chinese company GREE which is selling millions of heatpump does COP of 5 and works down to -30c So this video is just mehhhh, there is a world out there Matt and this company will be dead in a short while since there are companies that does better with just 1 single stage compressor

Induction cooking is awesome, I've made the change about two years ago, but I'll never get rid of old my propane stove, or the multi fuel generator, I don't use it often, but it is better to be prepared than to be sorry. It is all fun and games until a natural disaster, an emergency, maybe civil unrest or a war get you.

New England is having fewer and fewer very cold days because of climate change, so maybe the problem will take care of itself. For places where they still have very cold days, if the outside unit is installed underground (like in a detached cellar), it can remain within operable range even on very cold days.

This guy falls for each new scam all the time without researching anything at all ever.

High-quality food from the microwave? If it wasn't so sad, you could laugh out loud about it. What a load of crap ;))

👍🏻

Love u brother but taking a second look at studys from California based institutions would be prudent

0:44 Opera? You are aware that it's owned by a Chinese company that has to report all our data back to the Chinese gov't on demand, right? I used to love Opera, but I won't use it anymore.
