Electrek spoke with Heidi Gehring, associate director, cooling product marketing at Carrier HVAC, about the five essential things to know about this energy-efficient, cost-effective way to heat and cool a home.

Electrek: What’s a heat pump and how does it work?

Heidi Gehring: A heat pump is often mistaken for an air conditioner at first glance. What makes it different from an air conditioner is that it can both heat and cool your home using electricity and refrigerant.

In cooler months, heat is pulled from the outdoor air and transferred indoors; in warmer months, the system pulls heat out of the indoor air. Heat pumps have both an indoor and outdoor component. Each unit contains a fan and coil that operates either as a condenser (in cooling mode) or an evaporator (in heating mode). The fan moves the air across the coil and throughout the ducts in the home.

Electrek: Do heat pumps save you money, and what kinds of cost savings can be expected?

Heidi Gehring: Because heat pumps are more energy efficient, they can save you money on your heating and cooling bills. Your savings will vary based on the model you select.

Heat pumps are rated by their Heating Seasonal Performance Factor (HSPF2) – which is a measure of a heat pump’s overall energy efficiency during the heating season – their Seasonal Energy Efficiency Ratio (SEER2), and their Energy Efficiency Ratio (EER2). The higher the rating, the more energy-efficient the system.

Additionally, the US government’s Inflation Reduction Act of 2022 includes incentives for the installation of high-efficiency home heating and cooling products, including up to a $2,000 tax credit for high-efficiency heat pumps and up to 30% for geothermal heat pump systems placed in service between 2022 and 2032. Look into local and state programs, too, as many utilities and local governments offer heat pump rebates.

Electrek: Why is a heat pump better for the environment?

Heidi Gehring: Heat pumps rely on electricity rather than fossil fuels, making them a much greener choice. Improvements in technology in recent years also mean that heat pumps are more efficient than ever, requiring less electricity than older heaters, furnaces, and air conditioners.

Geothermal heat pumps are also available – they pull energy directly from the earth to heat or cool your home and can result in up to 70% savings on your energy bill.

Electrek: What features should you consider when comparing different models?

Heidi Gehring: Heat pumps vary in the number of stages or speeds they offer. Different speeds or stages can affect your comfort and the consistency of indoor temperature. Humidity plays a major role but is often overlooked. Two-stage and variable-speed offer better control because they operate for a longer period of time at lower speeds and use less energy. These pull more humidity out of the air than models with a single-stage compressor.

Variable-speed and two-stage models are generally quieter than single-stage models, and because they run longer, that means the air is run through the filter more, so it has less chance of becoming stagnant.

Electrek: When is the best time of year to install a heat pump?

Heidi Gehring: Usually in the spring or fall. During the coldest winter months and hottest summer months, demand for systems and technicians increases, so you may experience longer wait times and higher prices. Make sure you hire a professional. HVAC systems of any kind require expert knowledge for installation and are not a good DIY project.

If you’re switching from a traditional HVAC system to a heat pump, you may also need electrical upgrades. A professional HVAC installer can help you with that as well.

I found this cheap Chinese e-cargo trike that hauls more than your car!

I found this cheap Chinese e-cargo trike that hauls more than your car!

If you’ve ever wondered what happens when you combine a fruit cart, a cargo bike, and a Piaggio Ape all in one vehicle, now you’ve got your answer. I submit, for your approval, this week’s feature for the Awesomely Weird Alibaba Electric Vehicle of the Week column – and it’s a beautiful doozie.

Feast your eyes on this salad slinging, coleslaw cruising, tuber taxiing produce chariot!

I think this electric vegetable trike might finally scratch the itch long felt by many of my readers. It seems every time I cover an electric trike, even the really cool ones, I always get commenters poo-poo-ing it for having two wheels in the rear instead of two wheels in the front. Well, here you go, folks!

Designed with two front wheels for maximum stability, this trike keeps your cucumbers in check through every corner. Because trust me, you don’t want to hit a pothole and suddenly be juggling peaches like you’re in Cirque du Soleil: Farmers Market Edition.

To avoid the extra cost of designing a linked steering system for a pair of front wheels, the engineers who brought this salad shuttle to life simply side-stepped that complexity altogether by steering the entire fixed front end. I’ve got articulating electric tractors that steer like this, and so if it works for a several-ton work machine, it should work for a couple hundred pounds of cargo bike.

Featuring a giant cargo bed up front with four cascading fruit baskets set up for roadside sales, this cargo bike is something of a blank slate. Sure, you could monetize grandma’s vegetable garden, or you could fill it with your own ideas and concoctions. Our exceedingly talented graphics wizard sees it as the perfect coffee and pastry e-bike for my new startup, The Handlebarista, and I’m not one to argue. Basically, the sky is the limit with a blank slate bike like this!

Sure, the quality doesn’t quite match something like a fancy Tern cargo bike. The rim brakes aren’t exactly confidence-inspiring, but at least there are three of them. And if they should all give out, or just not quite slow you down enough to avoid that quickly approaching brick wall, then at least you’ve got a couple hundred pounds of tomatoes as a tasty crumple zone.

The electrical system does seem a bit underpowered. With a 36V battery and a 250W motor, I don’t know if one-third of a horsepower is enough to haul a full load to the local farmer’s market. But I guess if the weight is a bit much for the little motor, you could always do some snacking along the way. On the other hand, all the pictures seem to show a non-electric version. So if this cart is presumably mobile on pedal power alone, then that extra motor assist, however small, is going to feel like a very welcome guest.

The $950 price is presumably for the electric version, since that’s what’s in the title of the listing, though I wouldn’t get too excited just yet. I’ve bought a LOT of stuff on Alibaba, including many electric vehicles, and the too-good-to-be-true price is always exactly that. In my experience, you can multiply the Alibaba price by 3-4x to get the actual landed price for things like these. Even so, $3,000-$4,000 wouldn’t be a terrible price, considering a lot of electric trikes stateside already cost that much and don’t even come with a quad-set of vegetable baskets on board!

I should also put my normal caveat in here about not actually buying one of these. Please, please don’t try to buy one of these awesome cargo e-trikes. This is a silly, tongue-in-cheek weekend column where I scour the ever-entertaining underbelly of China’s massive e-commerce site Alibaba in search of fun, quirky, and just plain awesomely weird electric vehicles. While I’ve successfully bought several fun things on the platform, I’ve also gotten scammed more than once, so this is not for the timid or the tight-budgeted among us.

That isn’t to say that some of my more stubborn readers haven’t followed in my footsteps before, ignoring my advice and setting out on their own wild journey. But please don’t be the one who risks it all and gets nothing in return. Don’t say I didn’t warn you; this is the warning.

OPEC+ members agree to larger-than-expected oil production hike in August

OPEC+ members agree to larger-than-expected oil production hike in August

Eight oil-producing nations of the OPEC+ alliance agreed on Saturday to increase their collective crude production by 548,000 barrels per day, as they continue to unwind a set of voluntary supply cuts.

This subset of the alliance — comprising heavyweight producers Russia and Saudi Arabia, alongside Algeria, Iraq, Kazakhstan, Kuwait, Oman and the United Arab Emirates — met digitally earlier in the day. They had been expected to increase their output by a smaller 411,000 barrels per day.

In a statement, the OPEC Secretariat attributed the countries’ decision to raise August daily output by 548,000 barrels to “a steady global economic outlook and current healthy market fundamentals, as reflected in the low oil inventories.”

The eight producers have been implementing two sets of voluntary production cuts outside of the broader OPEC+ coalition’s formal policy.

One, totaling 1.66 million barrels per day, stays in effect until the end of next year.

Under the second strategy, the countries reduced their production by an additional 2.2 million barrels per day until the end of the first quarter.

They initially set out to boost their production by 137,000 barrels per day every month until September 2026, but only sustained that pace in April. The group then tripled the hike to 411,000 barrels per day in each of May, June, and July — and is further accelerating the pace of their increases in August.

Oil prices were briefly boosted in recent weeks by the seasonal summer spike in demand and the 12-day war between Israel and Iran, which threatened both Tehran’s supplies and raised concerns over potential disruptions of supplies transported through the key Strait of Hormuz.

At the end of the Friday session, oil futures settled at $68.30 per barrel for the September-expiration Ice Brent contract and at $66.50 per barrel for front month-August Nymex U.S. West Texas Intermediate crude.
