The Healsio is a "water oven" that bakes with water
What fundamentally sets Sharp's Healsio apart from other microwave ovens comes down to one thing: its heat source is water. It turns water from an internal tank into superheated steam above 100℃ and uses that steam to cook food — which is why the official product name is "water oven" (ウォーターオーブン). Regular models heat with microwaves, so the starting point is completely different.
Superheated steam tends to give off lots of heat to anything cooler than itself. When it touches cold food, it instantly condenses into droplets, transferring heat, and those droplets wash surface oil and salt off the food. That's the trick behind the Healsio's signature claim: baking with water cuts fat and salt. Reheated fried food comes back crisp instead of soggy, and grilled meat drips its fat away — both come from this mechanism.
A common misunderstanding, though: the Healsio isn't a steam-only machine. Everyday reheating and defrosting are done by microwave, and you switch to the steam mode depending on the dish. In reality it's "a daily microwave plus steam cooking when it counts," all in one unit. Understanding this helps you avoid the "this isn't how I thought I'd use it" moment.
Both carry the Healsio name, but the water oven covered here (model numbers starting AX-) and the automatic cooking pot "Healsio Hotcook (ヘルシオ ホットクック, model numbers KN-)" discussed later are entirely different categories. Start by deciding whether you want an oven that bakes and steams, or a pot you throw ingredients into and leave to simmer — that cuts down the confusion a lot.
Reading model numbers and the 4 grade lines
Water oven model numbers follow the pattern "AX-" + grade code + a final letter for the generation. Once you know it, you can read store shelves and online listings easily. There are four main grade codes. The final letter goes A→B→C→D from older to newer, so model numbers with the same grade code but a different last letter are newer and older (previous-model) versions of the same tier.
| Grade code | Position | Good for |
|---|---|---|
| LSX3 series | Top flagship | People who want to use every feature, including two-level cooking |
| RS1 series | Upper | Focus on auto cooking and a rich menu |
| N1 series | Basic | The core steam-baking function is enough |
| U1 series | Compact | Limited width, small households |
For example, "AX-LSX3C" reads as LSX3 = top line, C = a relatively recent generation. One generation earlier is "AX-LSX3B," two earlier is "AX-LSX3A." Lock in the grade code you want, then drop the final letter by one or two and compare prices — that's the basic move when shopping for a Healsio.
Capacity roughly splits into large, around 30L, and compact, around 22–26L, with the upper lines mostly at 30L. A safe rule: if you want two-level simultaneous cooking, you need the capacity and rack levels of a large, upper-line model; if you live alone or as a couple and want to save space, go with the compact U1. Grade and capacity tend to go together, so settle "the features you want" and "the size that fits" at the same time.
What's so great about the headline feature, Makasete Cooking?
You can't talk about the Healsio without mentioning Makasete Cooking (まかせて調理). With it, you just arrange food on the tray or rack and press start, without worrying about the amount or whether it's frozen, chilled or at room temperature. Two sensors inside (which check the food's condition) read the amount and temperature and automatically control cooking time and heat.
Makasete Cooking offers 4 main cooking methods.
- Grilling/"frying": Crispy while shedding fat. You can put frozen karaage and room-temperature vegetables together and it handles them nicely.
- Roasting: Grills meat and fish. Fat drips onto the tray below, so it's healthier.
- Stir-frying: It even handles stir-fries inside the oven.
- Steaming/boiling: Steamed vegetables and parboiling done with steam.
With a normal oven, you set "X℃ for X minutes" yourself. The key to Makasete Cooking is that even if you throw frozen chicken, chilled sausages and room-temperature broccoli onto one tray, it tries to cook each one just right. It fits how real fridges are — a mix of frozen and room-temperature items — which is why the feature has stayed popular for so long.
This is where models diverge. Even with Makasete Cooking, "two-level simultaneous cooking" — making different dishes on the upper and lower levels at once — is only on the upper lines (LSX3/RS1). If parallel cooking like frying on top and boiling below will be routine, go higher-end; otherwise a basic model still delivers the core. Also, some lower models instead have Okudake Grill (おくだけグリル), which cooks several foods at once but doesn't account for temperature differences between them. Don't confuse the two in the catalog.
Where do generations differ? Tips for buying an older model
New Healsio generations come out almost every year, but the core — steam baking and steaming, Makasete Cooking and Healsio reheating — stays almost the same. That's why previous models (older generations with an earlier final letter) are a realistic choice. That said, there are real "new generation only" differences, and whether you value them decides it.
| Differences in newer generations | What it is | If you don't care |
|---|---|---|
| AI consultation (Cook Talk / クックトーク) | New feature for discussing meal plans and recipes with generative AI | Older models cook just as well |
| More frozen-food menus | The microwave "Raku-Chin 1-pin" (らくチン1品) menu lets you cook more directly from frozen | Older models are fine if you don't mind defrosting first |
| Improved "restore the taste" features | Expanded tray functions and similar to improve reheating results | Basic reheating on older models is plenty |
In short: if AI consultation or one-step frozen cooking appeals to you, go new; if you only care about how dishes turn out, a model one or two generations back is fine. Previous generations tend to drop in price when a new one comes out, so "lock the grade code you want and drop the last letter by one" is a good balance of price and satisfaction. Only households that use lots of frozen food should double-check which generation supports it before deciding.
The Healsio Hotcook isn't a baking appliance
Same Healsio brand, but the Hotcook (model numbers like KN-HW) is an automatic cooking pot, completely different from the water oven. Rather than baking, you put ingredients in the pot, press a button, and it handles the heat and stirring by itself to finish stews and soups — basically "a pot you can walk away from." It's highly rated by dual-income households and anyone wanting less time standing at the stove.
The Hotcook's biggest feature is the Mazewaza Unit (まぜ技ユニット), which stirs automatically while cooking. Steam and temperature sensors monitor the heat, the arm opens, closes and rotates differently as cooking progresses, and it even adjusts how it stirs based on the amount and softness of the food. Recent models rotate faster, so beyond stirring they can mash and whisk. The latest generation can start stirring while ingredients are still firm, which cuts cooking time by up to about 30% compared with before for stir-fry-type dishes like mapo eggplant and twice-cooked pork.
Capacity is shown by the number in the model (24 = 2.4L, 16 = 1.6L, etc.).
- 1.6L class: The standard size, just right for 2–4 people. Easy to fit too.
- 2.4L class: For households that batch cook or make larger amounts. A 1.6L fills up with one meal for 3–4 people, so batch cooks are safer with 2.4L.
Timer cooking — set ingredients in the morning and come home to a fresh meal — is another popular feature. It heats first, then keeps food at a temperature where it's less likely to spoil, so it's designed with hygiene in mind. Still, don't push long timers with perishables like fresh ingredients in summer or dairy; follow the manual to be safe.
The trap when choosing is the product line. Automatic stirring (Mazewaza Unit) is on the "pro" line (KN-HW…), not on the separate "with" line (KN-MN…). If you want to add ingredients and fully walk away, choose a pro model with the Mazewaza Unit. Also, the Hotcook is a size bigger than a rice cooker and needs room for steam to escape, so check width, depth and clearance above first, along with the effort of washing its several parts.
A second tray, heatproof containers, and things you "didn't actually need"
Out of the box, the Healsio comes with everything you need to cook: a baking tray, a grill rack (depending on the grade), a water tank and a recipe book. Once you start using it, though, there are moments when you think "I wish I had one more of these." Conversely, some items that stores like to push alongside it end up unused in the back of a cupboard. The difference makes sense once you understand how the Healsio is built.
The machine assumes you'll use two trays
One selling point of upper Healsio models is heating trays on upper and lower levels at the same time. Yet some models come with just one tray. As you read through the auto menus in the manual, plenty of them casually say "uses 2 trays," and that's often when people first realize they're one short.
Two-level cooking isn't just about making twice as much. The Healsio's superheated steam circulates from top to bottom, so with meat or fish on top and vegetables or sides below, the fat dripping down flavors the vegetables — a nice bonus. With only one tray, you lose this option entirely. Two-level menus are often among the most-used auto menu numbers, so you'll likely want that second tray soon after buying.
When buying one, note that tray sizes and shapes differ by model. Even with the same Healsio name, trays aren't interchangeable between series with different interior widths. Note your model number and choose a genuine part clearly listed for it. A rim just a few millimeters off can wobble on the rails or keep the door from closing fully. This is where trying to get by with a generic product often fails.
People either love the rack or never use it
The grill rack is included or optional depending on grade. Its job is to lift food off the tray so steam reaches the bottom. It works well for toast, chicken thighs you want crispy-skinned, and dried fish — anything where you want the bottom dry too. On the other hand, fatty meat on the rack drips fat that smokes on the tray, so you end up adding water to the tray or using a liner.
How often you use it depends clearly on lifestyle. If you toast bread every morning, the rack is almost essential. Healsio toast dries only the surface while keeping moisture in, giving you that "crisp outside, chewy inside" result naturally. If your household doesn't eat bread for breakfast, the rack may come out only once every few months.
Depth and material decide which heatproof containers suit the Healsio
Because the oven fills with steam, choosing heatproof containers is a bit quirky. First, you can't use plastic wrap. Strictly speaking, wrap melts or shrinks in superheated steam mode, so in steam modes you basically heat without it. Trying to "cover and reheat" like with a microwave is the first thing people trip on.
What you'll want instead is a heatproof glass container with a lid. Not an airtight one — just a lid that stops too much steam getting in while letting heat through. It's handy for reheating batch-cooked food or making small simmered or steamed dishes. Even in models with plenty of interior height, keeping depth to about 8cm keeps the container safely away from the upper heater.
For materials, heatproof glass and ceramics are easiest. Metal containers sometimes can't be used in auto menus that also use the microwave, so on a Healsio treat them as "oven and steam only." Silicone molds are handy for baking, but some pick up a distinctive smell under strong superheated steam, so it's wise to try one first before buying more.
If you use Makasete Cooking, start by getting just one or two heatproof containers that fit neatly on the tray. Once you can place a container on the tray and arrange food directly around it, you can make more dishes in one go.
Count parchment-type liners as a consumable
The more people use their Healsio, the faster they go through oven sheets (like the Cook-Per/クックパー brand). The reason is cleaning. Superheated steam melts fat off, so every time you cook, a mix of fat and water collects on the tray. Washing that every time is honestly a pain. With a liner, you just throw away the sheet and wipe the tray lightly.
However, steam doesn't reach the food where the liner is, so browning on the underside weakens. A realistic approach is to skip the liner for dishes you want browned and use it only for steam-leaning dishes or fatty meats. Keeping a roll near the unit makes things less of a hassle, so you'll use the Healsio more.
If you also use a Hotcook, an extra inner pot comes first
If you plan to use a Hotcook too, an inner pot ranks above a tray on your shopping list. After cooking, the Hotcook either switches to keep-warm or you put the whole pot in the fridge. With only one pot, you can't cook the next dish until you've transferred the food and washed it. If you rotate batch cooking, an extra pot is almost a must.
Some inner pots are fluorine-coated (nonstick). The standard stainless pot is durable, but curry roux and cheese dishes can burn onto it. A nonstick pot visibly reduces this, making washing up less stressful. If you use it daily, adding this type is likely more satisfying. Inner pots also differ in size by capacity, so check your unit's model number and capacity first.
Lower-priority items
Some things often get bundled in stores but don't need to be bought right away.
- Oven cleaners and special detergents. The Healsio has an interior cleaning mode — just add water and run steam, and most grime loosens. You can think about it once you hit burnt-on stains that won't come off.
- Lots of recipe books. The built-in auto menus and the included recipe book will keep you more than busy for the first few months. Network-connected models can add menus, so there's little reason to buy several paper recipe books upfront.
- Dedicated stands and racks. The Healsio needs ventilation space at the back and sides. You don't want to buy a rack first and then realize you can't leave the required gaps — decide on the location first, then find something that fits.
- Expensive oven gloves. The interior gets very hot so you need hand protection, but mitts without separate fingers make it hard to grip the tray edges. It's more practical to choose by whether you can grip the tray handles firmly than by price.
Use tap water in the water tank as a rule. Mineral water or filtered water is sometimes recommended, but mineral-rich water tends to leave deposits in the steam generator. Water without chlorine also spoils more easily in the tank, so manuals usually specify tap water. There's no need to pour in expensive water with good intentions.
The buying order, summarized
| Priority | Item | Reason |
| High | A second tray (upper models) | Unlocks two-level auto menus |
| High | Extra Hotcook inner pot | Keeps your batch cooking rotating |
| Medium | Lidded heatproof glass container | Replaces plastic wrap, which you can't use |
| Medium | Oven sheets | Makes tray cleaning dramatically easier |
| Low | Dedicated cleaner | The cleaning mode handles most of it |
| Low | More recipe books | Wait until you've tried the built-in menus |
To sum up, Healsio add-ons fall into just two groups: things that bring out the machine's performance, and things that make cleaning easier. The first are trays and inner pots; the second are liners and containers. Cover these four and you should be fine for a while.
Healsio vs its rival, the Bistro
The model always compared when choosing a water oven is Panasonic's Bistro. Both handle the basics of reheating and baking, but their strengths point in different directions, so the right answer depends on how you cook.
| Aspect | Healsio (Sharp) | Bistro (Panasonic) |
|---|---|---|
| Core heating | Bakes with superheated steam | High-power grill + speed |
| Strengths | Less fat and salt, steaming, handles mixed frozen/room-temp food | Two dishes at once for more efficient meals |
| Best for | Health-conscious, steam-focused cooking | Making several dishes quickly |
| Auto-cooking approach | Makasete Cooking: just place food and leave it | Efficient parallel cooking |
Roughly speaking, choose the Healsio if you want healthy cooking that sheds oil and salt, centered on steamed dishes; choose the Bistro if you want to put several dishes on the table fast and grill often. Neither is "better" — it's about where your cooking focuses. If you're curious, try the dials and touch panels in a store to get a feel for everyday usability.
Slightly surprising stumbles with the Healsio
Because the Healsio works differently, using it like any other microwave oven leads to confusion in predictable places. These aren't complaints about performance, but the "I could've avoided that if I'd known" kind. Let's go through them.
"The microwave is slow" is usually a mode-selection issue
This is the most common complaint right after purchase. Some upper-grade Healsio models don't have a microwave at all. They're positioned as water-oven-only machines, doing all reheating with superheated steam. With these, you can't heat a convenience store bento in a minute — it takes several minutes of slow steam heating.
Even models with a microwave may have auto-reheat set up in a "Healsio way." Healsio reheating adds moisture as it heats, so food doesn't dry out like in a microwave, but it takes longer. Bread comes back surprisingly moist, but it's not ideal on a rushed morning.
The fix is simple: before buying, check by model number whether it has a microwave. After buying, learn the manual microwave wattage setting for when you're in a hurry. If you set power and time manually instead of using auto menus, it heats as fast as a normal microwave. Most people who decide the Healsio is "a slow microwave" never tried manual mode.
If you're considering a water-oven-only model, make sure to check whether you have another microwave at home. Switching to just the dedicated unit means losing everyday tasks like reheating frozen rice in a few dozen seconds. Whether you can live with that decides whether a dedicated model works for your household.
Starting to cook with an empty water tank
The Healsio boils water into steam, so if the tank is empty, superheated steam cooking stops partway. An error appears, heating stops, and you open the door to find half-cooked food — almost everyone does this once.
The tricky part is that tank water "runs down during cooking." On long menus, even a full tank at the start can get close to empty. Especially for two-level cooking or long menus like roasting a big block of meat, make a habit of filling it up before you start. Leaving used water in the tank is also bad — water spoils inside, so the proper routine is to empty and dry it after cooking.
Quite a few people find this "fill before, empty after" routine annoying and stop using their Healsio. The best countermeasure is placing the unit so the tank is easy to pull out. When installing, check that the tank side isn't blocked by a wall or fridge. A few centimeters can make a big difference to your daily effort.
A wet interior and lingering smells
Since it uses steam, water droplets remain inside after cooking. If you close the door without wiping them, there's a distinctive smell next time you open it — especially after grilling fish.
A common mistake here is wiping it while still hot with a cloth soaked in cold water. The interior is enamel or stainless steel, and repeated sudden temperature changes are best avoided. The basic routine is to let it cool a bit, soak up the droplets with a dry cloth, and leave the door slightly open for a while to dry.
If smells have set in, use the interior cleaning mode. Running steam with water loosens buildup so it wipes off easily. For fish smells that still won't go, the classic trick of adding squeezed lemon or citrus peel to the water and running steam sometimes works. But some models specify what you can add during cleaning, so follow your manual.
Throwing anything and everything into Makasete Cooking
With Makasete Cooking, you arrange food on the tray, press a button, and sensors judge doneness by monitoring the food. Because it's so convenient, it's tempting to put everything in together. That's the trap.
The sensors stop heating based on the overall condition inside, so if you mix foods that cook at very different rates, one of them suffers. Put a thick chicken thigh and thin zucchini slices on the same tray, and either the zucchini turns mushy or the chicken is undercooked. Combinations that work follow a pattern, mostly explained by two rules: "match the thickness" and "match the moisture."
- Match the thicknessButterfly or cut meat to an even thickness. Cut vegetables into sticks about as thick as the meat. With even thickness, cooking times line up.
- Put watery items at the edgesItems that release water, like tomatoes and mushrooms, disrupt the steam flow in the center. Placing them near the edge of the tray reduces the effect.
- Pre-prep only the slow-cooking itemsLightly precook or thinly slice root vegetables and kabocha squash. Take this one extra step and you can truly leave the rest to the machine.
- Salt first, oil lightlySuperheated steam removes excess fat, so there's little point in using much oil. Salting before cooking gives seasoning that accounts for what the steam washes off.
Trusting the Hotcook's stirring too much and ending up with mush
The Hotcook's Mazewaza Unit stirs the pot at set times. Put in things that fall apart easily, and naturally, they fall apart. A classic example: you want chunky potatoes in nikujaga, choose a menu with stirring, and come home to something closer to mashed potatoes.
That's less a failure than a menu choice. The Hotcook has no-stir menus too — pick one of those, or switch to the manual "simmer (no stirring)" (煮物（まぜない）) setting when you want to avoid mushiness. Cut potatoes large and use no-stir, and they'll keep their shape.
There's also the opposite mistake: forgetting to attach the Mazewaza Unit. Do this with curry or stew and the roux at the bottom burns. Get in the habit of checking the unit is attached under the lid before you start. The unit is removed and washed every time, so it usually happens when you wash and dry it and forget to put it back.
Running the Hotcook without enough liquid
The Hotcook is known for waterless cooking, but that means "cooking only with the moisture from the ingredients," not "you don't need water." Choose a waterless menu with only low-moisture ingredients and it simply burns. These menus assume vegetables that release water, like tomatoes, onions and napa cabbage, so keep that in mind when adapting recipes your own way.
Adding too much water is a mistake too. The Hotcook heats in a nearly sealed state, so far less evaporates than in a pot on the stove. Bring a stovetop recipe over as-is and you get a watery, bland stew. The standard rule when adapting recipes for the Hotcook is to cut the liquid.
The inner pot has a maximum capacity line. In waterless cooking, ingredients can swell during heating, so avoid filling right up to the line. Leafy vegetables in particular are easy to overfill — they look like a heap raw but sink once cooked.
Realizing after installation that the door won't fully open
The Healsio's door drops down toward you. The open door extends horizontally, so you need enough space in front of it. Push it deep into a counter and the door opens, but pulling out the tray becomes awkward.
What people often miss when measuring is how far the open door sticks out and the space to step back while holding the tray. The first is in the catalog; the second you have to secure yourself. Can you hold a hot tray in both hands and take half a step back? Actually moving your body in the planned spot is the surest way to check.
Each model also specifies ventilation space at the back and sides. Some models are strict about space above, so if you'll place it under a wall cabinet, always check the height clearance. Steam escapes upward, so a wooden shelf right above can deteriorate over time.
Buying an older model to save money and missing a feature you needed
When generations change, features aren't just added — configurations can change too. Pay particular attention to network connectivity. Adding menus and linking with the smartphone app only work on supported generations. When choosing an older model, don't decide just on how far the price has dropped; check by model number whether the features you plan to use are in that generation.
Even within the same generation, interior capacity, number of levels, number of trays and sensor types differ by grade. "It's a Healsio, so it bakes with superheated steam" holds for all, but the fine control of Makasete Cooking and whether two-level cooking is possible depend on grade. When comparing an older upper model with a newest lower model, these differences are what to weigh.
Measuring your space and buying smart
Because it's so feature-rich, the Healsio is an appliance people often regret with "I can't make full use of it" or "it doesn't even fit." Work through these steps before buying and you'll avoid almost all mismatches.
- Decide: oven or HotcookThe steam-baking water oven (AX-) or the leave-it-alone cooking pot (KN-)? They serve different purposes, so settle this first.
- Pick a grade by the features you'll useFor two-level cooking or AI consultation, go upper/new generation; if the core is enough, go basic or an older model. Don't pay top prices for features you won't use.
- Measure for capacity and installation spaceBeyond width, depth and height, you need clearance above and at the sides for heat. Large models are heavy, so check the delivery route too.
- Drop the final letter and compare pricesLock in the grade code, then compare the total cost against one and two generations back. Previous generations tend to drop right after a new one is announced.
- Judge by total cost including warranty, installation and rewardsCompare the "real cost" including extended warranties and points back, not just the sticker price.
As for when and where to buy, for large cooking appliances like the Healsio the best timing is when older models drop after a new model launch, especially when that overlaps with year-end shopping season or big sales. Each online mall is different, so here are some Healsio-specific things to watch.
- Beware of model-number traps: Even within "LSX3," the final letter means a different generation. Jump at the cheapest search result and you may get an older generation than you wanted, or a newest one that isn't good value. Always compare prices using the full model number (including the last letter).
- Points and coupons matter more for big appliances: Since the price is high, extra points back or coupons make a big difference. Before buying, check each mall's official pages to see whether you can stack sale periods with point-boost campaigns. Reward rates and conditions change over time, so don't assume — always check the latest on each official site.
- Compare installation services too: For heavy models, whether unpacking, installation and old-unit pickup are available changes the effort involved. If the price is the same, looking at the total including these extras helps avoid regrets.
Prices change by season and retailer. This article only gives rough guidelines like "the ¥X0,000 range" or "one generation back"; for actual amounts, please check current prices on each online store or retailer. Comparing right down to the final letter of the model number is the surest way not to overpay for a Healsio.
FAQ
How is a "water oven" different from a regular microwave oven?
The decisive difference is that its heat source is water (superheated steam). As the steam touches food and transfers heat, it also washes surface oil and salt away, making it well suited to cooking with less fat and salt. Everyday reheating and defrosting are still done by microwave, though, so the accurate picture is one unit that covers both a daily microwave and "steam baking when it counts."
How do I read a model number like "AX-LSX3C"?
It's "AX-" + a grade code (LSX3 = flagship / RS1 = upper / N1 = basic / U1 = compact) + a final letter. The letter goes A→B→C→D from older to newer generations. Models with the same grade code but a different final letter are newer and older versions of the same tier, so lock in the grade and drop the letter to find good-value older models.
What's the difference between Makasete Cooking and Okudake Grill?
The core of Makasete Cooking is that sensors read the amount of food and the differences between frozen, chilled and room-temperature items, then cook them automatically, handling mixed foods nicely on one tray. Okudake Grill can cook several foods at once, but doesn't account for temperature differences between them. If you want to cook frozen and room-temperature items together, choose a model with Makasete Cooking.
Can I cook different dishes on the upper and lower racks at the same time?
That "two-level simultaneous cooking" is only on the upper lines (LSX3/RS1). Even with Makasete Cooking, basic and compact models may not support it. If you want to regularly cook in parallel — frying on top, boiling below — choose a higher-end model with more capacity.
Is there a difference in results between the latest model and an older one?
The core — steam baking and steaming, Makasete Cooking and Healsio reheating — is nearly the same across generations, so in terms of cooking results alone, a model one or two generations back rarely makes a big difference. The differences are AI consultation (Cook Talk) and one-step cooking from frozen. If you don't need those, an older model is a great pick for both satisfaction and price.
Should I buy a Healsio oven or a Hotcook?
They do different jobs. To bake, steam or grill inside an oven, get the water oven (AX-); to put ingredients in a pot and leave stews and soups to cook, get the Hotcook (KN-). No single unit does both, so the quickest way to decide is by which matters more on your table: baking and steaming, or hands-off simmering.
How do I choose a Hotcook size and line?
The number in the model shows capacity (16 = 1.6L / 24 = 2.4L, etc.). 1.6L suits 2–4 people; 2.4L is safer if you batch cook or prep larger amounts. The product line also matters: automatic stirring (the Mazewaza Unit) is on the pro line (KN-HW…) but not on the with line (KN-MN…). If you want to fully walk away, choose a pro model.
What should I watch out for with installation and delivery?
Water ovens need clearance above and at the sides for heat, so measure the surrounding space, not just the unit. Large models are heavy, so check the delivery route, the load capacity of the surface and the ground connection according to the manual. The Hotcook is also bigger than a rice cooker and needs room for steam, so it's best to secure a spot for it first.
I've heard the Healsio uses a lot of electricity. Is that true?
Superheated steam requires boiling water to a high temperature, so there are periods of higher power draw than simple microwave heating. But cooking times aren't much different from a gas oven, and less prep work and deep-frying oil handling partly offsets this. If it concerns you, a practical approach is to use manual microwave for quick reheating and superheated steam only for slow roasting.
