Pro-Style Ranges, Who, What and Why

February 25, 2009 By NightOwl

We’ve all seen them, those big, shiny ranges that are often the centerpiece of a new kitchen or remodel. The question is do you need one?

You might be interested in one for the style it adds to your home even if the added power that comes with the equipment is not something you’ll use. Professional style ranges, like restaurant stoves, generate more heat than a standard range – the ovens and the gas burners on top have a higher BTU (British Thermal Unit) output than conventional kitchen ranges, but unlike restaurant stoves, they’re specially insulated. And, unlike conventional kitchen stoves, you will need a hood for ventilation, just as in a restaurant kitchen.

An advantage of a professional-series range is that the top gas burners burn hotter, allowing you to boil, saute or steam faster, but “you can also actually simmer on a low flame without burning the bottom of your pot,” says James Kita, sales manager for Metro Builders Supply in North Little Rock, Arkansas.

Most of the ranges have convection ovens, which use fans to spread heat throughout the oven cavity to provide an even temperature throughout. You’ll probably use more gas for a pro-style stove than a conventional one, Kita says. But as far as energy-efficiency is concerned, unlike refrigerators, dishwashers or washing machines, “they don’t rate these ranges because it’s not a machine that’s running all the time.”

There are also additional points to consider: they weigh more conventional ovens, so installation will likkely cost more;they might require additional insulation in the kitchen, and there is the additional expenditure for a hood.

Professional style ranges are available from multiple manufacturers such as Viking, Thermador and even Kenmore and GE. These companies identify them generally as “Professional Series”. Prices range from $2,000 to $12,000, depending on the brand and the size of the stove – they vary in width from 30 to 60 inches.

Thermador’s Newest Cooktop Technology

February 23, 2009 By NightOwl

Thermador has released its newest cooktops making it almost unnecessary for us to monitor our cooking. The infrared sensor technology which they have named Sensor Dome, is available in electric cooktops.

In the electric models, the retractable sensor dial utilizes an infrared beam to continuously measure heat from the cookware. Sensor Dome automatically cycles the burner on and off to maintain the precise temperature needed while preventing boil over. The result is time-savings combined with superior cooking performance, without the guesswork or the need to constantly adjust the temperature.

In addition, Sensor Dome works in conjunction with the exclusive new CookSmart® program, which is currently available on Thermador’s advanced Masterpiece wall ovens. Designed again to save consumers time and effort, CookSmart offers nine pre-programmed temperature modes to perfectly prepare a variety of common recipes, including pasta, potatoes and vegetables, as well as assist with deep frying.

It also operates a keep warm function on all elements, child lock for unintended cooktop use and fast preheat that quickly reaches the high temperature needed and then cycles down to the preset level. In addition, the series offers the 36” cooktop (with one sensor) with a center element that is 13” in size at 4,000 watts, making it the largest and most powerful electric cooktop in the industry. For those consumers who still prefer the intuitive turn of the dial, Thermador’s electric cooktops are also available with mechanical knob controls.

This cooktop is part of Thermador’s Masterpiece and Masterpiece Deluxe Series and is available in both 30″ and 36″ sizes. They retail for around $1,300 -$2,000 depending on the style and options you select.

February 16, 2009 By NightOwl

Induction cooking is continuing its rise in popularity and the manufacturers are responding. If you’ve been hearing about induction cooking, but haven’t a clue how it works, you can read about it here, where we explain all the details for you. Including an explanation of why only half that chocolate bar in the picture is melting .

GE is offering their answer to consumer interest by debuting a freestanding induction range in their Profile series. GE plans to offer the induction cooking technology exclusively in the Profile Series.

The range comes with a 3700-watt output element and will be available in a variety of colors, finishes and sizes. This range will be available in Spring 2009.

Whirlpool’s Eco Kitchen Line

February 10, 2009 By NightOwl

According to the US government, kitchen appliances use the bulk of our household energy consumption. In addressing the need to save energy, Whirlpool has introduced their Eco Line. The line is designed to be as much as 290 percent more efficient than previous models and includes a Resource Saver refrigerator, Resource Saver dishwasher and Energy Save range.

With energy use equivalent to powering a 60-watt light bulb, the Resource Saver refrigerator exceeds Energy Star standards by 10 percent. To help stretch the dollar even further and better preserve food, the refrigerator’s 6th Sense technology automatically adjusts cooling to bring existing food to the desired temperature in half the time. A Fast Cool button immediately drops the refrigerator and/or freezer temperatures to accommodate new food additions, such as hot leftovers.

The dishwasher uses one-third less water and energy than dishwashers manufactured seven years ago. The savings is the result of greater water pressure to break up more food more efficiently. Synchronized spray arms clean dishes on the upper rack first, followed by the lower rack, resulting in enhanced cleaning performance.

Also in the Eco Kitchen line are two ranges equipped with an Energy Save mode. The feature conserves electricity when the oven is not is use. Similar to a computer’s sleep mode, it dims extra features such as the digital clock and control display.

The dishwasher retails for about $800, the range $700 and the refrigerator, which will be available in March, for about $2,000.

Appliance Manufacturers are Aiming at Boomers

December 31, 2008 By NightOwl

What’s next? The Baby Boom generation is everywhere. As a child of the 60’s I’ve often had mixed emotions towards them – annoyance at how much attention they get combined with gratitude that they cause so many changes that I will benefit from in the future. One of those changes is happening now in the appliance manufacturing business. As boomers age, they are increasingly staying in their own homes and have the income to modify those homes accordingly. Appliance manufacturers want to get a piece of that. According to the Wall Street Journal, changes are being made.

In the kitchen, General Electric Co. is designing ovens with easier-to-open doors and automatic shut-off burners. A joint venture of Germany’s Bosch and Siemens AG has introduced a glass cook top for its premium Thermador brand designed to prevent boil-overs. Minnesota-based Truth Hardware reports booming sales for its remote-controlled window motors.

“This population is far more demanding and will refocus designers” on individual consumers, says Joe Coughlin, director of the Massachusetts Institute of Technology’s AgeLab, which studies design and engineering for an aging population.

Among appliance makers, Whirlpool Corp. has long tested products with potential customers who are deaf, blind or arthritic. The testing with arthritis patients helped prod the Benton Harbor, Mich., appliance maker to offer pedestals that raise the height of washing machines and clothes dryers for customers with back problems.

A pedestal beneath this Whirlpool dryer reduces stooping when removing laundry.

Whirlpool also offers washing machines with large knobs that make louder-than-usual noise when they’re set, for customers with limited vision or arthritis. “It’s not one of those little prissy knobs,” says spokeswoman Audrey Reed-Granger. One model introduced last year plays musical chimes to indicate washing temperature or other features.

At GE’s consumer and industrial headquarters in Louisville, Ky., designers use “empathy sessions” to help develop new refrigerators, stoves and dishwashers. Industrial-design intern Joanie Jochamowitz, 22, wraps her knuckles with athletic tape and wears blue rubber gloves to simulate arthritis. She shoves cotton balls in her ears to simulate hearing loss, dons special glasses to simulate macular degeneration and puts dried corn kernels in her loafers to simulate aches and pains. She grabs a walker. Then she tries to peel potatoes.

“I don’t want to get old,” she says, as she hobbles around the kitchen, fumbling with potato peelers and stove controls, and nearly spilling a pot of boiling water.

GE began the empathy sessions last year so its young designers could better appreciate how consumers use appliances. “When you’ve got designers that are 25 or 30 years old, it’s very hard for them to understand what someone in their 60s or 70s experiences,” says Kim Freeman, a spokeswoman for GE Appliances.

The company also arranges focus groups where consumers cook a meal in a GE model kitchen while staffers watch through cameras and one-way mirrors. And GE videotapes appliance users in their homes. The summaries from these tapes are used in brainstorming sessions about design changes.

“We note what they are doing. We see if those behaviors happen more than once and why,” says Marc Hottenroth, industrial design leader for GE’s Consumer and Industrial unit.

These efforts have prompted several changes in GE product designs, including brighter LED lighting that improves visibility inside new models, such as one with a French-door refrigerator atop a bottom freezer. This year, GE introduced a single-wall oven with two cooking spaces that can operate at different temperatures. Its research shows boomers cook and entertain more frequently and like the two-ovens-in-one concept. Some models can be raised off the ground for easier access. “You don’t have to reach in as far,” says Ms. Freeman. She says it prevents people from stooping awkwardly, losing their balance and burning themselves on the hot stove.

GE has new dishwashers and washing machines that allow users to put in an entire bottle of detergent a few times a year rather than a smaller amount for every load. The machines are designed to reduce confusion and make housework less of a chore, particularly for older consumers.

Appliance manufacturers hope these design changes will buoy revenue. Sales and profits in the U.S. appliance industry are down this year because of the housing bust, the stock-market slide and the economic slowdown. But for the long term, the appliance industry expects big returns because of baby boomers and hopes of a housing rebound.

Consumers Like Touch Screen Technology

December 10, 2008 By NightOwl

My Oven has it and so does my new phone – touch screen technology is becoming hugely popular. Apple started it with the iphone and now manufacturers of everything from consumer electronics to white goods are trying to keep up. The cell phone industry in particular wants to compete with Apple’s iphone.

“Consumers are looking for displays with higher resolution, contrast, and more-sophisticated touch screen technology in applications that previously utilized simple LED or LCD displays,” says Gary Olson, director of engineering, Control Products (Chanhassen, MN, U.S.; www.controlproductsinc.com). “Appliance makers have high expectations from their control developers. Expertise in advanced features along with advanced graphics is necessary to keep pace with market demands.”

The latest product offerings from Electrolux feature control panels that appear “dark” and blank until touched to illuminate and reveal a bright and colorful display allowing operation of all functions. The displays on the new line of premium appliances use touch sensors to detect touch and tell the panel to turn on, and when touch is no longer sensed, they turn off to leave a sleek and blank display.

Even as touch screens become more popular, some suppliers are exploring the next advance to provide options that go beyond touch.

It seems uncharacteristic for a control panel to eliminate the need for an actual touch, but smart technologies are enabling it. The answer for WaveOn Technologies Inc. is a touchless sensor, designed to be so sensitive it can detect a near-touch from 3 in. away, even when placed beneath 10-mm-thick plastic.

Although the technology is now common with flat-panel TVs and glass range cooktops, WaveOn’s technology is pushing the envelope further. The company is looking into applications where a detection of movement might come in handy. One example is the kitchen, where hands are commonly messy with food preparation. Here the sensors could help consumers raise or lower radio or TV volume or answer a phone without touching a thing.

“The key concern of many consumers is that if [the control panel] looks elegant, it is likely to be fragile and less durable than systems they’re used to,” says Brenton Judge, engineering director, Defond Group Ltd. Defond in the United States includes Defond North America LLC (Raleigh, NC, U.S., www.dnagroup.com). “By giving customers a system that essentially has an infinite life span and is resistant to dirt and spillages at a minimal cost, we can boost the acceptance of electronic controls in the appliance market.”

To achieve this, Defond is placing smart digital control underneath the facade of traditional mechanical switches that consumers believe to be more reliable. The supplier says its specialty is control systems that simplify use by integrating instructions into the product itself via the display and adding sensors that enable a product to self-adjust according to how a consumer uses the product.

Roasting a Turkey in Your Convection Oven

November 26, 2008 By NightOwl

If you’ve got a convection oven, Thanksgiving is a great day to use it. The even heating that a convection oven provides is great for your turkey and baking. Here are some turkey roasting tips straight from the experts at eatturkey.com.
A whole turkey or turkey breast will cook in less time with more even results when a convection oven is used. The convection oven circulates preheated air around the oven cavity for faster and more even cooking. Depending on the manufacturer, it is recommended the traditional roasting times be reduced by 10 to 40 percent. Usually both roasting temperature and time are reduced when using a convection oven. In such cases, the convection oven cooking temperature is lower to 300 degrees F.

The formula for conversion is different for each convection oven. Some manufacturers provide the conversion formulas on the front control panel of the oven.

The newest convection ovens feature an electronic thermometer probe that assists in more accurate roasting. The temperature probe should be set to the desired internal food temperature of 180 degrees F and inserted in the inner thigh. The electronic thermometer probe monitors the internal temperature and will alert the chef when the desired temperature is reached.

With or without the automatic thermometer, it is important to use a thermometer to ensure the internal temperature of the turkey reaches 180 degrees F in the thigh and 170 degrees F in the breast. If the turkey is stuffed, verify the stuffing temperature registers 165 degrees F.

NTF Convection Oven Open Pan Method Guidelines for a Fresh/Thawed Turkey Roast on the Lowest Rack Position
Cooking Method	Cooking Temperature	Weight Unstuffed	Estimated Cooking Time	Weight Stuffed	Estimated Cooking Time
Roast	300 degrees F.	14 – 18 lbs.	2 1/4 to 2 1/2 hrs.	14 – 18 lbs.	2 1/2 to 3 hrs.
Roast	300 degrees F.	18 – 22 lbs.	2 1/2 to 3 hrs.	18 – 22 lbs.	3 hrs. to 3 1/2 hrs.

Other Hints:

1. The preferred method is to roast the turkey in the center of the lowest rack or oven shelf so the top of the turkey will be centered in the oven. If two racks must be used, place the turkey on the lowest or middle rack. When baking with two pans, position the pans in opposite corners of the oven. Place the pans so one is not directly over the other.
2. Basting is not necessary when using the convention mode of roasting. If a special sauce or marinade is used, baste the turkey during the last hour of cooking.
3. The hot air must circulate around the turkey for even heat distribution. For best results, allow 1-1/2 to 2 inches of space around the turkey, including other pans as well as the oven walls.
4. If the oven door is opened frequently, there will be heat loss and cause longer roasting times.
5. The wings and drumsticks may brown more quickly and should be covered with foil to prevent over browning.
6. If the turkey is lightly tented with foil to reduce surface browning, be sure the foil is secured so it will not blow around and impair the fan action.
7. If the turkey is to be cooked in a closed oven bag or completely encased in foil, convection roasting is not necessary.

Remember these safety tips from the USDA:

Always wash hands, utensils, the sink, and anything else that comes in contact with raw turkey and its juices with soap and water.

Storing Your Leftovers :

Discard any turkey, stuffing, and gravy left out at room temperature longer than 2 hours; 1 hour in temperatures above 90 °F.
Divide leftovers into smaller portions. Refrigerate or freeze in covered shallow containers for quicker cooling.
Use refrigerated turkey and stuffing within 3 to 4 days. Use gravy within 1 to 2 days.
If freezing leftovers, use within 2 to 6 months for best quality.

Reheating Your TurkeyCooked turkey may be eaten cold or reheated.

In the Oven

Set the oven temperature no lower than 325 °F.
Reheat turkey to an internal temperature of 165 °F. Use a food thermometer to check the internal temperature.
To keep the turkey moist, add a little broth or water and cover.

In the Microwave Oven

Cover your food and rotate it for even heating. Allow standing time.
Check the internal temperature of your food with a food thermometer to make sure it reaches 165 °F.
Consult your microwave oven owner’s manual for recommended times and power levels.

Should You Fix the Old Appliance or Buy a New One?

November 7, 2008 By NightOwl

It’s a common question – when your appliance needs repairs is better to fix it or start looking for a new one? Often fixing the broken appliance can take days or even weeks if the parts are not available. A new one can often be purchased and installed within hours. But is buying a new appliance the right choice?

“We surveyed 13-thousand of our subscribers, covering more than 20-thousand broken products, and plenty of them had complaints about the repairs they got,” said Celia Kuperszmid-Lehrman from Consumer Reports.

The biggest problems were with electric cooktops and wall ovens.

“The parts were very difficult to find and the repairs often took two weeks or more to get done,” said Kupersmid-Lehrman.

When it comes to dryers, washers, and other larger appliances, the survey showed people have much better luck using an independent shop once the warranty is up, rather than a factory-authorized service center.

But Consumer Reports says sometimes an appliance just isn’t worth fixing.

“You should replace it if the repair is going to cost more than half the price of a new model.” said Kupersmid-Lehrman.

Additionally, Consumer Reports says that it is not necessary to buy an extended warranty, as the cost for repairs, if needed will likely be about the same as the cost of the warranty.

Energy Star Might Not be Such a Star

November 3, 2008 By NightOwl

Most consumers who are shopping for a new, energy efficient appliance know to look for the Blue EnergyStar label. The Energy Star label alerts shoppers to supposedly very energy efficient appliances. Many appliances also have a yellow energy guide label. That label tells shoppers specifically how much energy they can save by buying that particular appliance.

Buying an efficient appliance really can help save money by saving energy. Over the past five years, the nation has saved over $61 billion according to the Web site EnergyStar.gov. That translates to a reduction of greenhouse gases equal to taking half the country’s vehicles off the roads for one year.

There’s a problem though, according to Business Week, consumer and environmental groups say it’s often too easy for companies to win the right to display the star. According to descriptions from the Department of Energy (DOE), which manages the Energy Star appliance program, the coveted logo should ideally appear on dishwashers, refrigerators, and other appliances that score in the top 25% for energy efficiency in their categories. But in 2007 some 60% of all dishwasher models on the market qualified, the DOE says. The year before, 92% of them hit the mark. “If the DOE gives Energy Star to everyone, eventually it’s worthless,” says David B. Goldstein, a director at the Natural Resources Defense Council.

NO INDEPENDENT AUDITS

This past summer the nonprofit Consumers Union complained that some companies were gaming the system. Its testing labs discovered that two refrigerators—one from Samsung and one from LG Electronics—displayed the logos but only measured up if their icemakers were switched off. When the icemakers were on, the machines exceeded the power consumption stated on their Energy Star labels by 65% and by more than 100%, respectively. “Consumers don’t buy a fridge with this sort or feature to leave it off,” says Steven Saltzman, a deputy editor at Consumer Reports. It turned out that when the refrigerator rule was revised in 2001 and 2004, the icemaking feature was rare for this type of model, and there was no requirement to turn it on during the tests. Spokespeople from both LG and Samsung say the companies are in full compliance with DOE standards.

Critics also gripe that there is no independent auditor for appliance testing. The DOE can spot-check products, but it mainly relies on companies to test rivals’ wares and to complain if something looks fishy. Such complaints are rare—and it’s not just consumers who suffer. Federal and state governments require the Energy Star for billions of dollars of purchases each year. Last month, Texas offered a statewide sales-tax-free day for Energy Star goods. If the mark loses credibility, that could weaken official efforts to improve efficiency.

Until this issue is resolved, read those yellow labels carefully, the fact that an appliance carries the Energy Star label no longer seems to mean that it meets the highest standards of efficiency.
