What Size Heat Pump Should You Buy for Your Home?

It's summer, and that means your home is going to need cooling if you want to stay comfortable as the temperatures rise. Although you could add a few of the best window air conditioners to cool down your home, but a good heat pump system might be the better option for you. It's always a good idea to keep an eye on the thermostat, but choosing the right technology can make it even easier to maintain the perfect temperature.
Heat pumps can be a great option for homeowners. They offer a few benefits -- they're up to 50% cheaper to run than standard central air conditioners, according to the US Department of Energy. They're also useful in both hot and cold weather. If you're among the 78% of US adults stressed out about energy bills, as found in a recent CNET survey, you would do well to pick the right heat pump.
If you want to get the best out of a heat pump, it's crucial to choose the right size for your home. You should avoid spending money on a pump that's too powerful for your needs and needs more energy, or one that's too weak for your needs and needs to run harder to keep up with the space.
So how do you pick the right one? We've got all the answers to your questions, below.
The importance of finding the right size heat pump
It might seem like the size of your heat pump isn't that important. After all, what's the worst that can happen if it's a bit too small or too large? You might be surprised to learn just how important it is to find the right size. Having a heat pump that's either too small or too large can result in unnecessarily high energy costs.
If your heat pump is too small for your home, it likely won't work properly. You could end up paying higher heating and cooling bills because the heat pump will struggle to heat and cool your home. Because the heat pump has to work harder to get your home to the right temperature, you can also expect to pay higher repair and maintenance costs.
On the other hand, oversized heat pumps will produce more energy than you need, which wastes energy and reduces efficiency.

How to size a heat pump
There are a couple of different methods you can use to find the right size heat pump for your home: Manual J and square footage. We'll discuss each of those in further detail below.
Manual J
Manual J calculation is the industry standard of sizing a heat pump. It was established by the Air Conditioning Contractors of America to help determine the proper size heat pump for your home based on eight different factors. The eight factors that Manual J considers are:
The local climate, including how many days per year you need heating and cooling
Your home's square footage and layout
How many windows you have and where they're located
Your home's air filtration
The insulation quality in your home
How many people live in your home
Your preferred temperature
Heat-generating appliances in your home
Square footage
There are a lot of factors that go into calculating your heat pump size, and it can be complicated to determine how each of those affects your heat pump needs. Luckily, there's a simpler approach you can take to choose the right size heat pump.
In general, every 500 square feet of your home will require one ton of air conditioning capacity. Here are some guidelines to help you determine how many tons you'll need:
500 square feet: 1 ton
1,000 square feet: 2 tons
1,500 square feet: 3 tons
2,000 square feet: 4 tons
2,500 square feet: 5 tons
3,000 square feet: 6 tons
It's also important to know what each ton equals in BTUs, or British thermal units, which is the measurement used to determine heat pump sizing. Use this chart to help you determine the BTUs needed for your home:
Heat pump size guide
undefined Home size (in square feet) Heat pump size (in tons) Heat pump size (in BTUs) 500 square feet 1 ton 12,000 BTUs 1,000 square feet 2 tons 24,000 BTUs 1,500 square feet 3 tons 36,000 BTUs 2,000 square feet 4 tons 48,000 BTUs 2,500 square feet 5 tons 60,000 BTUs 3,000 square feet 6 tons 72,000 BTUs
Once you know the appropriate number of BTUs required for your home's heat pump, you can start shopping for the right one. Remember that you can also work with an HVAC expert who can help offer some guidelines and advice.
The bottom line
Finding the right heat pump size for your home is critical when it comes to saving money on energy and keeping your home at the right temperature in both the winter and summer. Sizing your heat pump may seem difficult at first, but it's actually pretty simple to figure out. And luckily, there are plenty of heat pump sizing calculators available online to simplify the process further. And once you know what size heat pump you need, the process of finding the right one should be a breeze.

Here's My Experience With 5 Cheap Gadgets I Bought From AliExpress

If you're shopping online, you may have noticed products from Temu and AliExpress often come up in your shopping search. These items are so cheap that you may wonder if it's really a steal or if you should stay away. I was in that boat as well. And I love a good YouTube video where the host tests cheap tech from low-cost retailers. So, curious as I am, I decided to try my hand at testing cheap home products from the popular discount marketplace, AliExpress. Now, when shopping for a new piece of home hardware, gaming gear or audio tech, cheap tech usually equates to low-quality performance. But as I've come to learn, that's not always the case. Rules for the experiment Products must cost less than $15. Devices need to be cheaper than a mainstream equivalent. Weird devices are more likely to make the list. I'm happy to report it was an authentic experience with a mix of good-ish products and some really bad ones. From best to worst, here's how my AliExpress order played out. Best: Tuya Zigbee smart USB adaptor switch It's the smallest plug in my smart home. John Carlsen/CNET USB chargers for lighting and small devices occupy far too much space in my smart plugs, so I always wondered if I could get a USB smart plug. I got the Tuya Zigbee Smart USB Adaptor Switch -- which includes three USB-A ports -- for a measly $5.02. Tuya devices like these are hidden gems for smart home enthusiasts, though they aren't always the easiest to work with. I'm glad it was easy to link to my SmartThings home automation system. It's not much more than an on/off switch, but I like the fact that I don't need a bulky USB multiport charger to run the few small USB devices on my nightstand. You can't control the ports independently -- and the power output is too low for charging most devices, but it's a good option for trickle-charging portable speakers or headphones. Plus, it can connect to practically any USB power supply, including empty ports on my computer. The Smart USB Adaptor Switch earns an A for value and functionality. As a Zigbee device, it's also less of a cybersecurity liability than any Wi-Fi device from AliExpress and Temu. Better: USB-powered ceiling fan A handy little ceiling fan. John Carlsen/CNET Ceiling fans have always been out of reach, since I live in an archaic apartment without them. This means relying on a fleet of air circulators in my bedroom and office. But what if renters could add a ceiling fan without the hassle of begging the property manager to install one? Enter the tiny ceiling fan I got for $14. I like the design of this fan, especially the 12-foot USB cord, which is long enough to reach a ceiling hook without much effort. The fan is surprisingly quiet and uses three power settings. Still, it's not particularly powerful, with the highest setting producing a light breeze from a few feet away. The speed and timer controls are easy to learn, which is great because the entire manual is written in Chinese. You can get the gist of the manual by using Google Lens to translate the text, but it's largely unnecessary. I give this product a B+ for being useful, albeit in niche settings where normal ceiling fans aren't practical. Good: Tuya Zigbee water sensor The water sensor worked OK but I'm not sure why it came with three reset pins. John Carlsen/CNET Unlike Tuya's smart USB switch, the Tuya Zigbee water sensor didn't properly connect to my SmartThings system on the first try. SmartThings classified it as a generic Zigbee device -- it couldn't see when the sensor detected water. This is a textbook example of Tuya's devices not always playing nicely with smart home hubs. So I rolled up my sleeves and dug into the SmartThings Edge Driver Builder, a developer tool for assigning drivers to smart home devices. After selecting my Tuya leak sensor from the list of devices in my smart home, I chose the Zigbee Water Leak Sensor driver and configured it as a water sensor. Like magic, the sensor started working. It's pretty responsive, and I like that it uses common AAA batteries. The extra effort might be worth the $4.59 I paid for the Tuya Zigbee Water Sensor, but I can't give it more than a C+ for someone who wants out-of-the-box smart home compatibility with SmartThings. I can't gauge whether it's great for other smart home platforms, but I suspect it's even better in Home Assistant. Now Playing: Testing Temu Tech So You Don't Have To 13:52 Worse: Smart Wi-Fi clock movement mechanism No hands on deck. John Carlsen/CNET I recently began transitioning most of the analog clocks in my home to tickless clock movements, which are less annoying than the ticking of a second hand when you're trying to fall asleep at 2 a.m. Let's try a smart Wi-Fi clock movement mechanism to set the time automatically like the digital clock on my Google Nest Hub. What followed was one of my most frustrating setup experiences in years. Out of the box, the clock I bought didn't come with any hands for seconds, minutes or hours. I spent far too long trying to fit some leftover hands from a previous DIY project, only to find that the clock didn't work. The included instructions, which came on a sheet of printer paper, were not helpful. They don't say that you need to remove the gray "locating needle" from the back of the clock before it will work. This pin locks the gears in place at Noon, likely to keep the clock aligned during shipping and when putting on the hands, which makes sense on a Wi-Fi clock that sets itself. It took two hours before I got it working. Plain-text passwords are visible to everyone. John Carlsen/CNET I'm even more disappointed with the Wi-Fi connection, which is not even close to secure. Anyone can open the clock's Wi-Fi connection to see your network's name and password. So glad I used my phone's hotspot for a temporary network. I give this product, which costs $14.01, a D- for working as advertised, even if it takes a while, and comes with a major Wi-Fi vulnerability. However, it's not the worst product by a long shot. Worst: Smart portable clothes dryer It's not supposed to be this droopy. John Carlsen/CNET I got the Beauty-Health Store smart portable clothes dryer for just $12.32. I won't waste your time: This is the most dangerous product from my AliExpress order. How do I know this? It quite literally melted about 2 hours into my very first drying session. The plastic in this product is not heat-resistant in any way. It didn't even dry a single shirt completely, so there's no reason to buy a cheap portable clothes dryer when laundromats can handle much larger drying loads for a fraction of the price. When I went online to see if other customers experienced this problem, I noticed the product page was no longer available. With my suspicions confirmed, I won't even delve into the features of this terrible product. Instead, I'll use it as an example to reinforce why buying generic electronics from AliExpress, Temu, Wish and other cheap retailers is risky. With certain categories of tech, you're gambling on your safety and privacy. As you can imagine, this device earns an F for being unsafe. Now, excuse me while I navigate the 90-day AliExpress return policy, which is one bright spot. Hopefully, it fares better than these last two products.

Game-Changing Wind Turbines Harvest Underused Resource Close To The Ground

Winds of Change: Kevin Wolf, CEO and co-founder of Wind Harvest Jimmy Dean, the country musician, actor and entrepreneur, famously said: 'I can't change the direction of the wind, but I can adjust my sails to always reach my destination.' A new wind turbine from a California startup, Wind Harvest, takes Dean's maxim to heart and applies it to wind power generation. It goes after untapped, abundant wind. Wind Harvest is bringing to market a possibly revolutionary but well-tested vertical axis wind turbine (VAWT) that operates on ungathered wind resources near the ground, thriving in turbulence and shifting wind directions. The founders and investors – many of them recruited through a crowd-funding mechanism — believe that wind near the ground is a great underused resource that can go a long way to helping utilities in the United States and around the world with rising electricity demand. The Wind Harvest turbines neither seek to replace nor compete with the horizontal axis wind turbines (HAWT), which are the dominant propeller-type turbines seen everywhere. These operate at heights from 200 feet to 500 feet above ground. Instead, these vertical turbines are at the most 90 feet above the ground and, ideally, can operate beneath large turbines, complementing the tall, horizontal turbines and potentially doubling the output from a wind farm. The wind disturbance from conventional tall, horizontal turbines is additional wind fuel for vertical turbines sited below. Studies and modeling from Caltech and other universities predict that the vortices of wind shed by the verticals will draw faster-moving wind from higher altitude into the rotors of the horizontals. For optimum performance, their machines should be located in pairs just about 3 feet apart and that causes the airflow between the two turbines to accelerate, enhancing electricity production. Kevin Wolf, CEO and co-founder of Wind Harvest, told me that they used code from the Department of Energy's Sandia National Laboratory to engineer and evaluate their designs. They believe they have eliminated known weaknesses in vertical turbines and have a durable and easy-to-make design, which they call Wind Harvester 4.0. This confidence is reflected in the first commercial installation of the Wind Harvest turbines on St. Croix, one of the U.S. Virgin Islands in the Caribbean. Some 20 turbines are being proposed for construction on a peninsula made from dredge spoils. This 1-megawatt project would produce 3000 megawatt hours of power annually. All the off-take from this pilot project will go to a local oil refinery for its operations, replacing propane generators. Wolf said the Wind Harvester will be modified to withstand Category 5 hurricanes; can be built entirely in the United States of steel and aluminum; and are engineered to last 70-75 years with some refurbishing along the way. Future turbines will avoid dependence on rare earths by using ferrite magnets in the generators. Recently, there have been various breakthroughs in small wind turbines designed for urban use. But Wind Harvest is squarely aimed at the utility market, at scale. The company has been working solidly to complete the commercialization process and spread VAWTs around the world. 'You don't have to install them on wind farms, but their highest use should be doubling or more the power yield from those farms with a great wind resource under their tall turbines,' Wolf said. Horizontal wind turbines, so named because the drive shaft is aligned horizontally to the ground, compared to vertical turbines where the drive shaft and generator are vertically aligned and much closer to the ground, facilitating installation, maintenance and access. Wolf believes his engineering team has eliminated the normal concerns associated with VAWTs, like resonance and the problem of the forces of 15 million revolutions per year on the blade-arm connections. The company has been granted two hinge patents and three others. Four more are pending. Wind turbines have a long history. The famous eggbeater-shaped VAWT was patented by a French engineer, Georges Jean Marie Darrieus, in 1926, but had significant limitations on efficiency and cost-effectiveness. It has always been more of a dream machine than an operational one. Wind turbines became serious as a concept in the United States as a result of the energy crisis that broke in the fall of 1973. At that time, Sandia began studying windmills and leaned toward vertical designs. But when the National Renewable Energy Laboratory assumed responsibility for renewables, turbine design and engineering moved there; horizontal was the design of choice at the lab. In pursuing the horizontal turbine, DOE fit in with a world trend that made offshore wind generation possible but not a technology that could utilize the turbulent wind near the ground. Now, Wind Harvest believes, the time has come to take advantage of that untouched resource. Wolf said this can be done without committing to new wind farms. These additions, he said, would have a long-projected life and some other advantages: Birds and bats seem to be more adept at avoiding the three-dimensional, vertical turbines closer to the surface. Agricultural uses can continue between rows of closely spaced VAWTs that can align fields, he added. Some vertical turbines will use simple, highly durable lattice towers, especially in hurricane-prone areas. But Wolf believes the future will be in wooden, monopole towers and to reduce the amount of embodied carbon in their projects. One way or another, the battle for more electricity to accommodate rising demand is joined close to the ground.

The Permian Basin is Fueling America's Electric Future

The growth in US power demand is surging to its highest rate in decades, driven first by the electrification of oil and gas production and then by the build out of data centers. While still below the 5-10% growth seen in China, the world's first 'electrostate," the US power sector is experiencing rapid structural growth. The country is delivering more than a 3.5% annual power demand growth rate for the first time in several decades, potentially positioning the US as the world's next 'electrostate,' despite the strong oil and gas focus of the Trump administration. Nationwide electricity consumption increased by around 200 terawatt-hours (TWh) in the last 10 years, with data centers already accounting for about 50% of the growth. Our updated assessment suggests that in the next decade, growth is likely to be four times faster, with more than 800 TWh of consumption added between 2024 and 2034. We expect the commercial sector – largely data centers – to drive ~60% of the growth. Meanwhile, the electrification of the transport, industrial and residential sectors are expected to deliver 90-150 TWh of growth each. While the market attention is focused predominantly on these data centers, we note that the electrification of the Permian Basin has been one of the most significant contributors to the nationwide demand growth in recent years. In fact, there is no other load zone in the country that has experienced the roughly 4 GW increase in average demand that Texas has seen since 2021. This translates into 30-35 TWh of added consumption and accounts for the entire industrial demand growth in Texas in the last four years. Using a combination of industry surveys, public data and Rystad Energy's proprietary data tools and models, we have been able to deconstruct the current 7.5 GW of Permian Texas grid power demand into individual contributors. Roughly 2.5 GW comes from residential and commercial sectors in West Texas and ~30% of that came on the back of accelerated Permian oil and gas development since 2017-2018. Upstream pad operations (mainly electric submersible pumps and other pad equipment) and gas compression contribute with ~2 and ~1 GW to the demand, respectively. The remaining 2 GW comes from direct electricity use at gas power plants, other oil and gas midstream facilities and liquids transmission. Some of these segments are positioned for significant growth in 2025-2035 regardless of oilfield activity outlook amid ongoing electrification of the basin. Hence, the Permian Basin will inevitably remain a critical contributor to nationwide demand growth. By Rystad Energy More Top Reads From this article on
