Climate change has the odd effect of making many of us inordinately excited about appliances we never used to care about. Suddenly, all the background machines, which have up to now been unconsciously powering our lives, have taken on outsized importance. Some of them have the potential to provide the essential services we depend on while, at the same time, not destroying our planet like the fossil fuel powered machines of the 19th and 20th centuries.

Ductless heat pumps are a prime example. In the past, many of us used gas furnaces and boilers to heat our homes and burned fuels that emitted copious amounts of CO2 in the process. Now, with the magical heat pump, we have access to efficient electric technologies for heating and cooling that can be powered entirely by renewable energy, and thus be carbon neutral.

Brief History and Growth of Ductless Heat Pumps

Ductless heat pumps (DHPs) were developed in Japan after World War 2. They were invented and perfected on an island that doesn’t have easy access to fossil fuels, and so they are the ideal heating/cooling system for our modern world given they don’t rely on combustion and are also incredibly efficient.

They condition 90% of Japanese homes, and worldwide their usage is growing like crazy, with an expected doubling of heat pump sales in the next five years. In the UK, sales are projected to increase 20 fold, and in the US, some areas are seeing sales growth north of 40% every year.

My family has used ductless heat pumps for our heating and cooling since 2012 when we bought our house. The gas furnace that came with our house was old, and we made the decision to replace it with new ductless heat pumps. (A major perk is that mounting the units on the wall saved valuable floor space in the garage, formerly dedicated to the gas furnace, which we converted into an apartment). We had seen them used in Europe and figured, even 9 years ago when the electrification movement was in its infancy, that heating with efficient electricity would allow us to reduce our carbon emissions with the solar panels we planned to install on our roof.

What is Ductless?

But what is a Ductless Heat Pump (a.k.a. mini-split)? Basically, it is a heating/cooling system that is different from a traditional furnace in several ways:

1. DHPs don’t have air ducts. Rather than forcing hot air through potentially leaky ducts, ductless systems place an indoor device on a wall and an outdoor unit (similar to a typical AC unit) which provides heating and cooling. This means no air escapes through leaky ducts, creating more efficient conditioning.

2. DHPs don’t burn things. Ductless heat pumps use electricity to provide heating and cooling. Electricity is rapidly moving towards being fully renewable and thus will soon produce zero emissions (the Biden administration set a goal of 2035 for example).

3. DHPs are like refrigerators in reverse. Instead of burning fuel, ductless heat pumps create heating and cooling through refrigeration. This means they capture heat from outside (even when it’s cold) and move it into your house, and vice versa for cooling. It’s pretty magical. The refrigerants used by DHPs can be potent greenhouse gases themselves, but luckily the world is moving quickly to using better, more environmentally friendly refrigerants (check out this website for a new type of refrigerant called R32).

4. DHPs are incredibly efficient. This is because a) no air leaks through ducts b) they heat the room they are in (rather than the whole house), c) moving heat is vastly more efficient than creating it, and d) they use inverter systems (see below). As a result, they typically use three times less energy than old electric resistance heaters and six times less than gas. 

Demystifying a couple DHP terms 

Speaking of efficiency, let’s demystify a couple of terms associated with ductless heat pumps.

SEER — SEER is a number that measures how well a technology provides cooling. The higher the number, the more efficient the unit. Most new air conditioners have a SEER between 13 and 21, but ductless can often see a SEER over 30, which gives you an idea of how efficient they are. If you’re in a warm climate, SEER is especially important.

HSPF — HSPF stands for Heating Season Performance Factor and complements the SEER rating in that it measures how efficiently a heat pump heats a space. The minimum required HSPF rating in the US is 7.7. An 8.5 score is considered good, and over 10 is excellent. If you’re in a cooler climate, where the predominant energy use is for heating, HSPF is most important.

Example of SEER and HSPF ratings

I interviewed Tim Sharp, from the Heat Pump Store here in Oregon, which has installed thousands of ductless heat pumps over the last decade. He said that you’ll want your DHP to be most efficient in heating if you’re in a cold climate, and cooling if you’re in a warm climate. People in the northern US should probably focus on HSPF, while in the southern US, people should focus on SEER. Tim also said that investing in a DHP with higher scores will be more expensive up front, but the additional cost usually pays for itself over time through energy savings.

Ductless Heat Pumps in Cold weather

I also learned from Tim that DHPs were originally developed to provide only cooling (like a refrigerator), yet they have “constantly gotten better for heating purposes in almost every environment.” If you’re in a cold climate, you probably want to think about the “extended capacity” models, which are able to provide more heating. According to Tim, they don’t cost significantly more and offer more BTUs per hour output. Read more on how to use heat pumps in cold climates here

Ductless vs. Ducted

If you have existing ductwork in a space, you may consider a different approach when transitioning to heat pumps.  Not all heat pumps are ductless. You can get central heat pumps that work with a typical central AC system, and provide heating that blows that hot air through ducts. These central heat pumps are not much more expensive than central air conditioning, and many people think that swapping out every central AC system for a ducted heat pump is an important strategy to quickly get us off natural gas and reduce carbon emissions.

Ductless, on the other hand, is a no-brainer when you’re adding heating or cooling to a room without any ductwork. And DHPs also offer greater efficiency as well as economic and environmental advantages over a central ducted heating system. In addition to the efficiencies mentioned above, ductless heat pumps use inverter technology, which means they run at variable speeds. Tim from the Heat Pump Store compares this to starting your car at a red light. Inverters slowly rev the engine when starting and stopping, while typical central AC systems gun it and brake hard, meaning they are much less efficient. All DHPs use inverter technology, while virtually all conventional (ducted) heat pumps don’t, meaning DHPs are much more efficient. 

My family chose ductless heat pumps in our house, rather than a whole house heat pump, even though we had existing ductwork from our old gas furnace because of the increased efficiency.

Humidity and air quality

Though ductless heat pumps help to dehumidify a room, it is not their primary purpose. In places with humidity problems, a separate dehumidifier may still be necessary. Similarly, DHPs have built in air filters, but can’t generally filter air to the extent that ducted systems do with high rated MERV filters. Tim from The Heat Pump Store said that air filtering is considered a separate system, from heating/cooling, in places where heat pumps are most prevalent, and people typically buy another device for air filtration. 

Brands

There are four leading brands of ductless heat pumps: Mitsubishi, Fujitsu, LG, and Daikin. Most of the top brands are Japanese, given they first developed the technology. This NY Times article has some solid reviews on each of these four brands.

Choosing a contractor

Finding a good installer is important. Many contractors may try to talk you out of electric heating and cooling (and into gas). Plus, you’ll want someone to help you correctly size a system for your needs. That means someone with lots of experience in ductless heat pump systems as well as a good reputation and reviews. Getting three bids is always a solid strategy. One pro tip is to look on a manufacturer’s page for contractors in your area that are certified to install their product.

Cost and Aesthetics

As Tim told me in our interview, ductless heat pumps aren’t a panacea. Any technology has its downsides. As my wife points out, the indoor equipment that sits high on your wall takes up space and isn’t the most beautiful thing in the world. Ductless Heat Pumps can also be expensive. A system with a single indoor unit can run $3,000–$5,000, but if you’re putting multiple “heads” throughout your house, costs can quickly go over $10,000. 

Yet, for me, after 9 years of heating and cooling our house with ductless heat pumps, and with the climate emergency we find ourselves in, any drawbacks to ductless heat pumps are vastly outweighed by their immense benefits. Heat pumps are the heating and cooling technology for this era of climate change, and ductless heat pumps are the most efficient versions of this technology. They allow us to get off fossil fuels and efficiently heat and cool, in any climate, with clean electricity.

The Kia EV5 is now on sale as one of Canada's most affordable electric SUVs

Kia now has one of the most affordable electric SUVs in Canada. The EV5 is now on sale, starting at $43,495 CAD.

Kia opens EV5 orders in Canada

The EV5 is the electric SUV we want in the US, but we will likely never see it. After opening online orders on December 4, Kia revealed prices for the entire 2027 EV5 lineup.

Surprisingly, buyers can choose from nine trims, with prices ranging from $43,495 CAD for the base Light model to $61,495 CAD for the flagship AWD GT-Line Limited edition.

Outside of the Light trim, all EV5 variants are offered with front-wheel or all-wheel drive. Upgrading to AWD costs an extra $2,500 CAD.

Likewise, all EV5 trims, except the Light variant, are powered by an 81.4 kWh battery, providing up to 460 km (285 miles) of driving range. The entry-level Light uses a 60.4 kWh battery, good for a driving range of up to 335 km (208 miles).

All EV5 models come with a built-in NACS port, nearly 30″ of screen space in a curved panoramic display, heated front seats, and Kia Connect with OTA updates.

The interior features Kia’s new Connect Car Navigation (CCNC) infotainment system with dual 12.3″ driver display and touchscreen navigation screens, plus a 5″ climate control screen. The setup includes wireless Android Auto and Apple CarPlay capabilities.

Kia grouped the EV5 trims into tiers based on what buyers are looking for. As expected, the Light FWD trim is the best value for your money.

For those looking for a little more driving range, the Wind FWD offers up to 460 km range, while the Wind AWD is built for Canada’s harsh winters. Both include a heat pump as standard.

If you think Trump will bring tiny kei cars to the US, you might be as dumb as he is

If you think Trump will bring tiny kei cars to the US, you might be as dumb as he is

Multiple outlets are reporting on Donald Trump’s apparent effort to change US regulations to bring tiny Japanese kei cars to the US, but there’s little reason to think that effort will be serious.

Convicted felon Donald Trump has directed former reality TV contestant Sean Duffy to examine how kei cars, a category of Japanese microcars, could be brought to the US, calling them “cute.”

The statement was made yesterday at the announcement of a fuel efficiency rollback, which will raise your fuel costs by $23 billion and is explicitly intended to make cars bigger and less efficient.

And so, simply by reading the preceding two sentences, you should understand how unserious this effort is. At the same moment that a new proposal was announced to reduce fuel efficiency targets by a third, the same person who is trying to increase your fuel costs and make cars bigger and less efficient apparently also wants tiny efficient vehicles in the US. How does that make sense?

If Trump did know anything about how the auto industry works, he would not speak about making cars smaller at an event to announce rules explicitly intended towards making cars bigger – these are not compatible thoughts, and betray a lack of understanding of the reason he was even in the room to begin with.

Further, in addition to yesterday’s effort to remove CAFE rules, the EPA is currently trying to roll back President Biden’s improved exhaust standards which included a recognition of vehicle sizes becoming too large and a desire to reduce SUV/truck market share, and Mr. Trump is trying to place a 15% tariff on all Japanese goods, meaning higher prices for Americans if these cars were to come to the US.

Thinking more deeply about the reason why Mr. Trump might have mentioned kei cars to begin with, it is likely related to his recent trip to Japan. He went to Japan to negotiate an end to the unwise tariffs that he himself announced on one of America’s closest trading partners (despite that he does not have the Constitutional authority to apply them).

During that trip, he seems to have seen the tiny cars for the first time (or the first time he can remember, given his senility), and been enamored by them. So, he said yesterday (while flanked by Duffy, who showed apparent surprise as the flippant statement came out of his mouth):

“They’re very small, they’re really cute, and I said ‘How would that do in this country?’… But we’re not allowed to make them in this country and I think you’re gonna do very well with those cars, so we’re gonna approve those cars.”

-Donald Trump, upon witnessing a type of vehicle he should have known of by now, having spent 79 years globetrotting around this Earth, so how can he just be seeing this for the first time except if he’s senile.

Now, technically, here he says he wants the US to build the cars here, rather than import them from Japan. Kei cars are very popular in Japan, but rarer in other countries. Some other countries do have their own small cars similar to kei cars (for example, China’s 115-inch Wuling Mini EV), but Japan is where these vehicles have traditionally held the highest share.

There are various reasons for this, but one of them is due to the high density of Japanese cities. Kei cars are very space efficient for cities that are obsessed with space efficiency in a way that simply is not the case in the US.

Japanese cities are also connected by efficient, fast and reasonably-priced bullet trains, so getting from one side of the country to the other is easy to do without having to stuff the whole family into a vehicle that is under 134 inches long. And the regulatory regime in Japan has been built around kei cars, giving them certain advantages to incentivize their use.

Meanwhile, it’s nigh-impossible to convince any manufacturer to even build a sedan, hatchback or small SUV for the US, or to build any small-displacement vehicle. So this would require a massive change in consumer tastes, which of course manufacturers haven’t been particularly interested in leading, given they’ve been pushing SUVs for decades now.

That said, one of the reasons manufacturers have pushed SUVs is due to regulations which treat them more favorably than smaller vehicles. If those regulations were changed – and that’s what Trump and Duffy have floated – it could open the doors for smaller cars.

But there’s little reason to think either of them are serious about this, given the amount of work that would have to be done to change regulations, and given the work they’re currently doing to change the regulations in the exact opposite direction.

At a minimum, Federal Motor Vehicle Safety Standards (FMVSS) would have to change significantly. This is the set of rules governing safety requirements for all motor vehicles, with requirements for various vehicle classes that have been built and tweaked over time. And these requirements are tailored to how we build roads, infrastructure, and signage in this country, which differs from how these things are done in Japan or Europe or China.

While an effort to harmonize FMVSS and infrastructure standards with other countries would be admirable and has been desired for a long time in the auto industry, the enormity of the undertaking is much greater than a single flippant comment (from someone who probably doesn’t even know what FMVSS stands for).

And in fact, US regulations already do allow for exemptions to many regulations for low volume vehicles. So it already is possible to build small cars in the US, at least if you build fewer than 2,500 per year. So a startup focused on tiny cars could already get started here, and could have been selling kei-like cars all along (say, TELO, for example… but even they are offering a 152in truck, a foot and a half longer than a kei car, and with 500hp, about 8x more than a kei car).

TELO’s tiny truck next to a full size Dodge RAM

But why haven’t manufacturers made these cars already, then?

Again, going back to the above, regulations and manufacturers have both pushed vehicle sizes larger and larger, and consumer tastes have happily followed, with US drivers wasting more and more money and space on larger and more polluting vehicles.

There is a perception that these larger vehicles are safer (even though they aren’t, and we are currently nearing an all-time high in pedestrian fatalities), so if vehicles keep getting bigger as a result of regulations allowing them to, US consumers will be afraid to buy a car that’s even smaller than the smallest available today. And yesterday’s proposed rule explicitly claims, in its third paragraph, that smaller cars are undesirable for this reason (without recognizing that it’s actually the larger cars that are responsible this problem).

Kei cars are also typically less powerful than the average American car, which even Duffy claimed himself, saying “are they going to work on the freeways? Probably not” (even though most vehicles use about ~20hp to sustain highway speeds).

And given that the American consumer has been sold the dream of buying a vehicle not for what it will be used for, but for every conceivable purpose they could ever dream of using any vehicle for, it seems unlikely that many will line up for a car that they have been told can’t even get on the freeway.

After all, Smart cars did exist in the US, as have various other small vehicles, but they’ve always been marginalized, because the whole culture, manufacturing base and regulatory regime around cars and roads has been built to advantage large vehicles, not small ones.

So despite that microcar enthusiasts like myself want to see tiny cars in the US, the idea that manufacturers will suddenly scale up production of these vehicles in the US seems extremely unlikely without a concerted effort to show that they are welcome here and that there will be a market for them.

And I’m not convinced that concerted effort will be undertaken by people who are currently undertaking a concerted effort to do the exact opposite, and by someone who seems to change his mind with whatever stupid nonsense he happened to see 12 seconds ago on fox. Companies don’t build manufacturing facilities based on the whims of an idiot, they do so with clear and consistent policy that they can be certain will last through a vehicle model’s development and sales timeline (typically around ~14 years from start of development to end of production).

So I don’t think this is going to happen. Prove me wrong, I will be happy to eat crow here.

Northern California's largest non-Tesla fast charging hub is now online

Not-for-profit public power provider Ava Community Energy just brought its first EV fast-charging station online in downtown Oakland, California, and it’s a big one.

The new site features 18 Kempower DC fast chargers, making it the largest non-Tesla fast-charging hub in Northern California. The majority of the plugs are CCS, with a few NACS and one ChAdeMO plug. It’s near workplaces, housing, and close to the freeway for commuters.

The station is inside Oakland City Center West Garage, right in one of the region’s busiest urban neighborhoods. Nearly half of Alameda County’s residents are renters, so public fast charging is an essential service for EV drivers who can’t plug in at home. Ava says this is the first step in building a network of up to 15 stations focused on expanding equitable access to EV charging.

The new charging hub also lines up with Oakland’s 2030 Equitable Climate Action Plan, which puts frontline communities at the center of the city’s climate strategy. A big part of that plan is giving residents the infrastructure they need to switch to EVs, and supporting current EV drivers with stations that are reliable, accessible, and community-focused.

“Our goal is to expand access to clean, sustainable energy in large and small ways through increased usage of solar systems, more electric transportation via cars and electric bikes, which reduces tailpipe emissions, improving how people cook at home, and even how we heat our homes and water,” said Howard Chang, Ava Community Energy CEO. “Ava Charge is just one step in our overall goal to make the transition to carbon-free energy easier for all.”
