FIGHT BACK\Energy-efficient new appliances a plus.Byline: David Horowitz
As winter deepens, homeowners are naturally concerned about controlling energy costs, especially on heating. And it's certainly something to bear in mind when shopping for major appliances.
In the past few years, appliance manufacturers have made tremendous improvements in energy efficiency. In the long run, savings in operating costs operating costs npl → gastos mpl operacionales make high quality, better engineered appliances cheaper to own than ordinary, less expensive ones.
Refrigerators are the third largest users of household energy after space and water heating Water heating is a thermodynamic process using an energy source to heat water above its initial temperature. Typical domestic uses of hot water are for cooking, cleaning, bathing, and space heating. In industry both hot water and water heated to steam have many uses. . Twenty years TWENTY YEARS. The lapse of twenty years raises a presumption of certain facts, and after such a time, the party against whom the presumption has been raised, will be required to prove a negative to establish his rights.
2. ago, a typical refrigerator used 1,500 to 1,800 kilowatt hours of electricity a year. In most areas, that's about $120 to $145 a year at today's utility rates. And because refrigerators and freezers are so reliable, many old units are still in use.
But thanks to advances in compressors, motor designs and insulation, modern freezer-top refrigerators use only about half as much electric power. Side-by-side refrigerator-freezers are slightly less efficient than freezer-top models because the large doors let in more warm air each time they're opened. Optional features like automatic ice makers and door-front water dispensers also use more electricity. But even the fanciest new models cost less to operate than an old refrigerator.
Similar improvements have made dishwashers more energy-efficient. The best ones have dual pumps, sound-dampening insulation and internal heaters to bring the wash water up to sterilizing temperatures. Several models feature internal computers that monitors washing cycles for optimum efficiency. These units save both electricity and gas by reducing demand on the hot-water heater.
Washing clothes uses a huge amount of hot water every year. But a new Swedish-designed washing machine (storage) washing machine - An old-style 14-inch hard disk in a floor-standing cabinet. So called because of the size of the cabinet and the "top-loading" access to the media packs - and, of course, they were always set on "spin cycle". claims to cut water use from an average of 50 gallons per load to as little as 11 gallons. Asko washing machines also reduce water heating costs by heating the wash water internally to more than 200 degrees Fahrenheit, which is far hotter than you want your water heater set.
Water heaters themselves are undergoing significant design changes. New tankless models provide a constant source of hot water and usually cut energy use by around 15 percent. These units heat the water as it passes through a heat exchanger heat exchanger
Any of several devices that transfer heat from a hot to a cold fluid. In many engineering applications, one fluid needs to be heated and another cooled, a requirement economically accomplished by a heat exchanger. - there's no tank to keep hot at all times. And since there's no tank to rust out, these heaters can last a lifetime. Tankless heaters are available in gas, propane propane, CH3CH2CH3, colorless, gaseous alkane. It is readily liquefied by compression and cooling. It melts at −189.9°C; and boils at −42.2°C;. and fully electric models.
There are all kinds of ways to cut space heating Space heating is the heating of a space, usually enclosed, such as a house or room. A space heater keeps the air and surroundings at a comfortable temperature for people or animals, or even plants in a greenhouse. (and cooling) costs - good insulation, weatherstripping, double-pane windows and "intelligent" thermostats that reduce heating automatically at night or when the family is away from home during the day.
By constantly circulating air throughout the house, ceiling fans can help eliminate hot and cold spots, especially in homes with high ceilings and open lofts. That means the thermostat thermostat, automatic device that regulates temperature in an enclosed area by controlling heating or refrigerating systems. It is commonly connected to one of these systems, turning it on or off in order to maintain a predetermined temperature. can more accurately sense the temperature inside the house as a whole. But beware of cheaply made fans. They're often unreliable, and if the blades aren't carefully balanced, they'll develop a wobble wobble /wob·ble/ (wob´'l) to move unsteadily or unsurely back and forth or from side to side.

When shopping for any new appliance, check the federal energy guide sticker. That will let you compare the average annual cost of operating various models, and you can choose the ones that will pay you back in energy savings.
