Heat Pump Dryers Save Energy and Eliminate Potential Fire Hazards Conventional dryers use electric resistance or gas combustion to heat the air, then blow it over the clothes. The warm, moist air is then vented to the outside. The dryers that use heat pumps don't need vents, which save energy and eliminate potential fire hazards due to lint accumulation in the ducts. These machines also use lower temperatures, and are more gentle on clothes. They can take longer to dry than traditional machines. Aztec Appliance provides more details about these ventless washers. Efficiency You can save a lot of money on your electric bill by using a heat pump dryer. It consumes up to 28 percent less energy than a traditional dryer, according to Energy Star. It might not sound like much but if you wash 20 loads of laundry a week in Massachusetts where electricity rates are among the highest in the country it will save you hundreds of dollars over the course of 12 years. A heat pump dryer is similar to a dehumidifier. It begins with air that is heated by a compressor, and then sent through another set of coils to warm it even more. The hot air draws moisture out of the clothing and into the heat exchanger, where it becomes condensed. It then drips into a empty pan or a tube that can be connected to drain it. The cooled, moist air is then circulated back through the condenser coils until it is then heated and the cycle starts again. Heat pump dryers don't require an exhaust vent. They can be used in places where a conventional dryer would not be able to fit. They also are quieter and more versatile which makes them suitable for apartment spaces and other rooms with little space. They are also safer than dryers that have vents. Vents can ignite if they are not cleaned regularly. Heat pump dryers take longer to dry your laundry due to the fact that they operate at lower temperatures. In addition, since they function as a dehumidifier and release a lot of water during drying It is important to clean your heat pump dryer frequently. This is especially important if you reside in an area that is humid or if your clothes have a lot of moisture trapped inside them. You can check this regularly by cleaning and inspecting the lint filter and condenser coils. Also, you should clean the drain tube occasionally. Regular cleaning will keep the evaporator in good shape. Condensation The traditional way of drying clothes involves a fan blowing hot air over the laundry that is tumbling and then venting the warm, humid air out. This method uses a lot energy and requires an outside space for the venting. Heat pump dryers, also referred to as ventless drying machines recycle the air. They heat the air coming in by reusing some of the energy used to run the machine. They then condense the moisture that results into water that drains out the bottom of the drum. They are also smaller than vented dryers, and they can be built into a laundry area or even in an attic. Heat pump dryers, though popular in Europe and Japan are relatively new on the American market. They are now available in sizes that fit most home laundry rooms and can provide significant energy savings. Since they don't draw the indoor air outdoors, you won't need to clean your venting system or fix any issues that might arise. They function as refrigeration systems in refrigerators, with an air compressor that presses refrigerant within one set of coils to release heat and a set of evaporator coils that absorb warmth from the air that passes through them. The refrigerant that is heated circulates through the second set of coils to condense moist air. The refrigerant that has been cooled is then pumped back into the first coils, where it is reheated. The heat pump dryers require maintenance, just like other electric dryers to ensure their performance is at its best. Lint collects on the filters, as well as on the evaporator and condenser coils, and it's important to clean them frequently to avoid excessive wear. They also employ refrigerants that have an extremely high GWP, also known as Global Warming Potential. They must be recycled. Another issue to be considered is the fact that heat pump dryers generally take longer than vented ones to finish a load. This is due to the fact that the maximum temperature of heat pump dryers is lower at about 120degF. This means they will need to tumble a little more time before they are completely dry. Lint Screens The dryers of a heat pump come with a lint trap and venting system that must be regularly cleaned. A blocked vent can drastically extend drying times, and poses a fire risk. The exhaust of a vented dryer can reach temperatures that are high enough to ignite volatile oils and chemicals on clothes. A heat pump vent system requires a dehumidifier in order to eliminate moisture before air exits the dryer. A dehumidifier can also reduce energy costs by lowering the temperature of the hot water that is used to heat the air. The lint filter in a heat-pump dryer is finer and needs to be cleaned more frequently than those in the conventional dryer. The lint screen in the door opening can also collect lint. It should be cleaned regularly. The models with a heat pump have a heated drum, which means the interior of the machine must be free of residue and lint from dryer or fabric softener sheets. The heated drum walls might be required to be cleaned and inspected periodically, as they might require to be changed as indicated by the user's manual. Lint buildup in the dryer's exhaust hoses isn't only a nuisance, it's also a major fire hazard that causes an average of 2,900 home fires per year, according to the U.S. Fire Administration. Clean the dryer's lint exhaust pipe every year with wire brushes, or employ an air blower from the outside to eliminate lint from inside of the hose, as this Today's Homeowner how-to video will explain. It's safer to do this from the outside, as you can avoid getting lint on your face. If you're unsure of your ability to clean the duct, hire an expert to do it for you. If you are unable to feel air moving in the dryer vent, or your dryer takes longer to dry, it could be that there is a blockage of lint within the duct. Pick a day of the year to clean the venting system that is Labor Day, the beginning of spring, or at the end or beginning of daylight savings time – and stick with it. Installation Modern electric dryers are among the most useful features for homeowners. However, choosing the right dryer is essential for those who wish to cut down on their energy bills and also have a positive effect on the environment. For many these reasons, heat pump dryers are an ideal choice. In contrast to traditional vented dryers which make use of gas or electricity to heat air, and then blow hot, dry air into the drum to remove moisture and re-use the same air over and over, pulling the moist air out of the clothes and cooling it, allowing it return to the laundry room where it can be used again. They do not require chimneys, ducting, or a chimney to vent outside. They can be placed inside small spaces like laundry closets. They are ideal for tiny houses, additional dwelling units (such a laundry room or an apartment above the garage) or even additions. Also, because just click the following website is a reliable quality mark of energy efficiency heat pump dryers are often more efficient than traditional vented models. Heat pump dryers can be operated on standard 120-volt 15-amp circuits. This is a benefit for older homes with older wiring and can save you money on installation. However the fact that heat pump dryers are less powerful than other dryers means they are slower to complete a cycle. Because they don't go around like conventional dryers do, large items like sheets and towels could become a laundry sludge which is difficult to unravel. Some manufacturers attempt to solve this issue by turning off the tumble cycle for brief durations during a cycle. The dryers that use heat pumps also require more maintenance than other dryers. Lint can collect on the heat exchanger coils as well as the evaporator coils, requiring periodic cleaning or vacuuming to keep them running efficiently. Since dryers with heat pumps do not vent, they could also gather moisture on the inside of the dryer, leading to mold.
