Thank you - very informative!

Everybody blowing smoke about these things are not thinking

You're using an already conditioned space to operate this thing

I HAVE TO SAY THIS IS ALL FOR NOTHING A HEAT PIPE and a wood stove or a stove and a blue flame heater in my 1890 wood frame 2ksqf 3 cord wood 620 to my door , or 25 from the national forest 60 a month ele for ac and heat when Im lazy . I think we all make to much of NEW MORDERD like I did till I started doing this my self my home I built balloon with r13 and vapor and sheathing 1 in dry wall and .5in skim coat r30 in the attic coming now , my point is I have a sears and robuck Home in a historical area in the mountains of va I grew up in buffalo ny I was born in the blizzard of 77 , I have lived bad winter and most of the us is like va 3 months of ok winter -10 low 25 average for 30-45days we need to plan our homes better its layers all over but u can just rely on one thing with no redundancy

We've had a GE Profile for a year now, and we LOVE it - ESPECIALLY when compared to the standalone twins we had before! If the old washer didn't 'walk' across the floor, the dryer wouldn't DRY! BUT NOW, NOT ONLY will the Profile PAY FOR ITSELF in another year by cutting our power bill in HALF, but we no longer have to transfer WET clothes to the DRIER! PLUS now there's room for our FREEZER in the laundry room!

Thanks for all your information!

A lot of Gobley goop I’ve been putting them in for years… good down to 10 below. But they do run on 220 votes not 120 votes. Few have been in service for 7-8 years with out any issues. Definitely the way to go if you have room in the electrical panel for a 220 circuit

Thank you for teaching me, i can learn so much from you.

Been waiting for the saddle window units to hit the market. Another innovation would be a new-construction through-the-wall unit like hotel air conditioners & a unit that could be retrofitted into the stud space of existing walls.

A simple heated hose will take care of the freezing problem, duh.

All they need now is quality filters, but I doubt they make MERV 13 filters that small.

the portable one is great. don't know what brand I have, but the heat output was amazing. only bad point is the amount of water condensation that formed. had to put it in a small tub

I have an old gas water heater that isn't putting out enough hot water and needs to be replaced . However ,it is in a walk in crawl space under the house which stays nice an cool in the summer and is warmer than the outside temp in the summer so I think that might help in keeping my indoor temp stable.I'm concerned if putting in a heat pump water heater would mess all that up. Also, I called one of our major water heater stores and told them that I wanted to put in a heat pump water heater in my walk through crawl space and they thought that was a terrible idea. Is it a bad idea? Would it cause mold growth?

You should tell the whole truth, and electric blower of equivalent power to gas makes the same kind of noise. The noise is in the blower.

In the intro you said "It's something all of us can do in our own homes to reduce air pollution and carbon pollution." Don't forget noise pollution!

I missed this broadcast today. Glad you posted it, as I'm getting ready to get a grill for my household.

How many amps does this need? What if you have other things running on that same circuit. It will likely blow the breaker. Look at heaters and the draw they have.

Thanks!

Homeowner here who recently switched from a gas furnace to a heat pump. The first place to start is to _track your energy use._ Unfortunately, most contractors aren't data-driven and have the incentive to oversize your heat pump. You don't even need a tracking app or device. Just saving your gas and electricity bills for a whole year is enough.

Thanks

Just installed a heat pump in Canada the cold climate , what is anoying is advertising pumps to heat to -30 celcius with no problem , but forget to mention the 10k electric elements that automatically kick in . Why annoying is come clean and tell us the real story , I have backup gas furnace that will take over when the unit runs for hours and hours to try to heat .

What about superior downdraft system on a kitchen island

This is the first time I saw the backup heating elements. I know they’re weaker than a 240volt but still nice to have.

They need to make a 120 gallon to end all fears of running out of hot water until the technology advances enough to allow faster recovery.

Do electric induction cooktops require type I or type II hood ventilation systems?

One physical issue I have not seen addressed and is definitely an issue of concern with DIY is the size and strength required to install the window units. Even though I needed a larger capacity unit from the one I purchased, I could not lift the larger units. Instead I purchased two smaller units. The lightest unit I found still weighed 40 lbs and at 4'9" in height, had a difficult time lifting these units into place. More and more women and the aging population mean that people with less strength find themselves in a position of having to do these kinds of projects themselves. Larger and heavier units mean it will be difficult for this segment of the population to use/install.

Thank you for your knowledgeable and enlightening discussion. There is a dearth of useful info online, as they say, the genius is in the details. The saddles are a potentailly revolutionary solution. This should have been offered when minis were invented! Grab and go Saddle or no-wall-hole flex-cable minis are sorely needed (like the regrettably problematic 'Forest' offering, which to be honest, was mostly user mishandling due to unfamiliarity. And they only cooled.) Pleased to hear manufacturers are getting them developed. Every mobile home, cottage, boat, RV at the least! Seniors, off-grid, fixed income, spare room, basement. Deal breaker with minis right now is HVAC techs despise installing or repairing them! The PNW techs and others are overcharging, sabotaging installs which effectively sours widespread adoption. The industry needs to address this. And also, the manufacturers hate self installers. Costco makes a true DIY mini split, but instructions are deceptively incorrect! And the instructions specificallt state tech install; they void warranty for self installs, because of easily avoidable but undocumented install pitfalls. Few promote the exceedingly rare but true DIY aspect because of the return rate. DIY FYI: "EG4" offers TRUE non vacuum, quick connect self-install, AC/DC solar, and also regular AFFORDABLE minis. However; even 'TRUE DIY': no-vacuum, dual lines both precharged, quick-connect mini splits are a bit too much work average buyers. Getting the market to figure them out for precharged, quick connect mass adoption for HEAT, without wall holes, with flexible lines going through window, no-technician installs, and removable use is desperately needed, especially today with the economy. Elephant in the room is parts, warranty and service. Poor support for mass produced off-the-shelf Chinese units available to the consumer, and decreasing no doubt with age of unit. 1) tech aversion 2)manufacturer warrenty disqualification for self installs 3)no parts 4) scant availability of reversing valve true DIY window saddle mini splits working under 40 degrees

I always hang dry my laundry. In winter I set up my drying racks in basement.

Should push for walkable your city. Even greater rewards then electrifying your ides.

Say yes to Natural Gas

There is a outdated patent on a heat pump where it defrosts while heating, offering nearly double heating capacity. I wonder why all these people don't look at patent applications. It's amazing what's out there.

If I add a skylight to the roof of my water heater closet to bring more sun in, would that help the efficiency of my heat pump water heater?

I'm a contractor , and he's right, been in this business 50 years, yes I'm old, but i have supplemental in conjunction with the main unit. How many days are u going to be at max design (degree days on the design) ? People pay a huge sum of money for just a few days out of design. , so yes this guy's right supplement and save yourself money. Set your baseboard heat to supplement at a outdoor temp ,your contractor can set this up.

Heat pump dryers only seem to be £100 more than a condenser dryer or vented. Bearing in mind that you're saving 50p each load it will only take 200 loads to pay for it self. I do 4 loads a week, so will take less than a year and a half to get the difference back. Also Hotpoint have a 10 year warnaty so years of savings.

Such an informative and refreshing conversation (even as a layman) - shame to see so little views.

I'm using captions to try to spell the manufacturer for the three. But the captions are phonetic, not correct. Gree and Midea? And Gradiant? Would be nice if you spelled them. Or ensure captions are correct. I'm trying to locate a window unit like Gree for my small house, but no luck. On Google, at least. I rewatched video and see they are not yet on the market. I'm in Pacific Gas and Electric territory. Humboldt County California. Snowing today. Our electric rates have gone through the ceiling. All electric, mountain house, without gas mains. No option for gas. I'll follow your channel for updates on micro heat pumps. Please post videos as you learn more. 6,000 btu. 120 volt preferred. Maybe saddle type is more available?

So with net metering, the solar panel owners get to use the grid as their personal battery with no costs? Considering that rooftop solar is limited to homeowners who have the extra capital to pay for solar panels, how is this not just an additional handout to rich people?

net metering does not cost low income rate payers any additional money. Falsehood promoted by MONOPOLISTIC UTILITIES. the more solar, the fewer new GENERATION PLANTS THE MONOPOLY UTILITY gets to bid and collect their GUARANTEED RETURN on every dollar spent ! lower income renters and home owners should be provided more ez, simple financing programs, perhaps like PACE loans, linked to property tax bill. we need to raise a generation of ALTERNATIVE ENERGY AND ENVIRONMENTAL ACTIVISTS ! ..."Teach, .... your children well ....."

NET METERING ; local utilities must accept the transition to becoming a DISTRIBUTOER ONLY, except where they already own their elec. production generators or can install solar/wind farms that produce and distribute kwh at prices much lower than localized roof top, etc. sources. To encourage property owners to reduce CO2 emissions by installing SOLAR PV, utilities MUST BE MANDATED TO PAY FOR EXCESS PRODUCTION AT RETAIL RATES the same rates utilities charge customers. i ask that Electrify Now and it's affiliates post/email State PUC meeting dates and locations, along with one email address that each PUC COMMISSIONER WILL READ , for public/customer input. Fed, State and Local government financial incentives must be promoted for, public needs to ask for incentives, in order to get more consumers to buy solar, which causes THE LEARNING CURVE to REDUCE COSTS SIGNIFICANTLY, every time the number of installed systems DOUBLES !... see texts; THE BIG FIX, THE GRID, SHORTING THE GRID. ,,, to understand the corrupt , one sided PUC fee system.

Very nice presentation, thank you. I am curious to know what the switch over temp should be to my second fuel source (gas). I am in the Mid South with solar on my home, and want to maximize the carbon reduction. It is not a cold weather heat pump.

I currently have a standard 50 gallon 240v electric water. I understand the differences between the 120v and 240v Heat Pump water heaters. Assuming I would run the water heater on the most efficient mode 100% of the time, is there any advantage of downgrading my dedicated circuit to 120v and going with a 120v over 240v Heat Pump water heater from an electrical consumption perspective or will I get the same performance. I will add another variable to the question, I have an 18.5Kwh solar system (no battery) on my roof. It's my understanding both could run solely on solar. The standard electrical unit I have now mostly does on good sunny days. I live in Texas.

Is the LG Wash Tower combo 110 or 220v?

How much good will these new cold climate window units do if their price is only competitive with professionally installed mini splits? Why should the price ever become competitive with existing >40°F window heat pumps, already considerably more expensive than an AC and a space heater, if government programs will throw >$3000 per unit at fairly small 9000btu units.

Stupid question: if a conventional window heat pump can only withdraw heat from air down to 40°F and must then use resistance heating anyway, wouldn't it make more sense to use that supplemental heat to preheat incoming ambient air? All else being equal (which of course tends to never be the case) wouldn't raising 30°F ambient source air to 41° be a much better use of energy potentially allowing a COP return on that investment approaching the unit COP when operated above 40°? Besides if the outside ambient temperature is at or below 30°F it's supplemental resistance heat must be heating output air much more than 11° to meet comfort standards above body heat unless ambient inside air is kept to 87°F or more. Granted I'm not allowing for the ratio of outside source air flow vs the flow of conditioned interior air but still, wouldn't expending that additional supplemental energy _before_ the heat pump allow for more a greater COP than 1?

Good explanation of the challenges on Hydrogen around 44:20 -- what about Biofuels -- would they face the same challenges to the existing distribution/burners?

Thanks so much for the informative video. I'm looking at replacing the gas furnace in a home that we're renting out, so this is really great. Thanks especially for actually mentioning roughly what the costs are expected to be... though not until 59:30 in. 😞 At 51:34 and also at 68:15 you mention putting the information in Google doc... did you ever do that and if you did, could you share the link?

What about a commercial version for a coin-op hotel or Laundromat?

LOL... really drinking the change to electric kool aid. Try researching the 50s campaign of "Live Better Electrically" that was pushed by the Government to help the profits of G.E. and other giant corporations.
