Some Of The Most Ingenious Things That Are Happening With Heat Pump Dryers
Heat Pump Dryers Save Energy and Eliminate Potential Fire Hazards

Conventional dryers heat air with electric resistance or gas combustion and then blow it through clothes that are tumbling, and then release the warm, humid air outside. The dryers that use heat pumps don't need vents, which help save energy and eliminate potential fire hazards resulting from lint accumulation in the ducts.

These machines also operate at lower temperatures and are more gentle on clothing. They may take longer to finish drying than traditional machines. Aztec Appliance provides more details regarding these ventless washing machines.

Efficiency

You can save lots of money on your electric bill by using the heat pump dryer. According to Energy Star, it uses up to 28 percent less energy than a conventional dryer. It might not sound like much however, if you are doing 20 loads of laundry per week in Massachusetts where electricity rates are among the highest in the country, you will save hundreds of dollars over twelve years.

A heat pump dryer is similar to a dehumidifier. The heat pump dryer starts with heated air that is then circulated through coils to heat it even more. The hot air pulls moisture out of the clothing and is then pumped into the heat exchanger, where it transforms into condensed liquid. It drips into a pot which can be manually empty or connected to drain tubes. The cool, moist air is then circulated back through the coils of the condenser to be heated.

Heat pump dryers don't require an exhaust vent. They can be used in areas where a conventional dryer wouldn't be suitable. They are also more efficient and quieter which makes them suitable for apartments and other spaces with little space. In addition, they are more secure than dryers with vents, which could be an fire hazard if they are not cleaned regularly.

The dryers that use heat take longer to dry your laundry because they operate at lower temperatures. tumble dryers with heat pump is also essential to clean the dryer on a regular basis because it works like an air dehumidifier and can produce a lot of moisture during the drying process. That's especially true when you reside in a humid area or if your clothes are soaked with lots of moisture inside them. You can do this by regularly inspecting and cleaning the lint screen and the condenser coils. Also, you should clean the drain tube periodically. Regular cleaning will keep the evaporator coil in good working order.

Condensation

The traditional method to dry clothes involves the use of a fan to blow hot air over the laundry that is tumbling and then venting that warm, moist air to the outside. This method consumes a lot of energy and requires an outdoor space that is vented for the ducting. Heat pump dryers - also referred to as ventless dryers re-use the air instead. They heat the air that is coming in by reusing a portion of the energy that goes to power the machine. They then condense the resulting moisture into water, which drains out the bottom of the drum. They're also smaller than vented dryers, and can be incorporated into a laundry area or even an attic.

The dryers that are heat pump, although popular in Europe and Japan are relatively new to the American market. These dryers are now available in sizes that fit in most laundry rooms and can provide significant energy savings. And because they don't exhaust indoor air to the outdoors it isn't necessary to clean out your venting system regularly or deal with possible issues that could arise when you have a dirty venting system.

They are similar to the refrigeration system in refrigerators. They have a compressor which pressurizes refrigerant through one coil, and then releases heat. The evaporator coils absorb warmth from air passing through. The heated refrigerant flows through a second set of coils to condense the humid air. The chilled refrigerant is then recirculated back into the original set of coils and is heated to continue the process.

The heat pump dryers require maintenance, just as other dryers with electric motors to ensure their performance is at its best. Lint can accumulate on the filters and evaporator coils. It is crucial to clean these coils regularly to prevent excessive wear. And they use refrigerants with high GWP (Global Warming Potential) and therefore, they have to be properly recycled also.

They take longer than vented dryers in drying a load. It's because the maximum temperature of heat pump dryers is lower, at 120 degrees Fahrenheit. This means that they'll need to tumble a little longer before they're completely dry.

Lint Screens

Heat pump dryers have venting and lint trap system that needs to be cleaned on a regular basis. A blocked vent can dramatically lengthen drying times, and can pose a fire hazard. The exhaust from a vented dryer can reach temperatures that ignite chemical and volatile oils.

A heat pump vent system needs an air dehumidifier to remove moisture before the air leaves the dryer. A dehumidifier will also help you save energy by lowering the temperature at which hot water is heated to heat the air.


The lint screen of the heat pump dryer is more fine than conventional dryers, and therefore must be cleaned more often. The lint trap inside the door's opening is a good place for lint to build up, and it should be inspected and cleaned frequently.

The models with heat pumps also have a heated drum wall which means that the inside of the dryer needs to be kept free of lint fabric softener, dryer sheet residue. The heated drum walls may be required to be cleaned and inspected regularly, as they may require to be changed according to the user's guide.

Lint buildup in the dryer's exhaust hoses isn't only a nuisance, it's also a major fire hazard and causes an average of 2,900 home fires per year according to the U.S. Fire Administration. Clean the dryer's lint exhaust the hose every year using a wire brush or employ a leaf blower from outside to clear lint from the inside of the hose as this Today's Homeowner video provides. This is safer to do from the outside since you won't be able to see lint on your face. If you're not confident in your ability to clean the duct, hire an expert to handle it for you.

If you can't feel air moving through the vent of your dryer outside or the dryer is taking longer to dry than usual there may be an obstruction of lint deeper within the duct. Choose one day a year to clean the venting system - Labor Day, the beginning of spring, or the closing or the beginning of daylight savings time - and stick with it.

Installation

Modern electric dryers are one of the most useful features for homeowners. But selecting the right dryer is an important decision for those who wish to lower their utility bills and make an impact on the environment. The heat pump dryer is an excellent option for many. Unlike traditional vented dryers that utilize gas or electricity to heat air and blow the hot, dry air into the drum to remove moisture, heat pump dryers reuse the same air over and over by pulling the moist air away from the clothes and cooling it, allowing it return to the laundry area, where it can be used again.

Because heat pump dryers don't have to vent outside they don't require chimney or ducting and can be installed in small spaces like laundry closets. This makes them perfect for small homes, accessory dwelling units (such as laundry rooms in the basement or an apartment above the garage) and even additions. Heat pump dryers often perform better than traditional vented models since they are ENERGY STAR certified.

Heat pump dryers can be run on standard 120-volt 15-amp circuits. This can be an advantage for older homes with older wiring, and can save you money on installation.

They have lower power compared to other dryers, so they take longer to complete the cycle. Since they don't move back and forth like conventional dryers do, large items like sheets and towels can turn into a laundry sausage that is difficult to remove. Some manufacturers attempt to address this issue by reversing the tumble cycle for brief durations during the course of a cycle.

The dryers that use heat pumps also require more maintenance than other dryers. Lint can accumulate on heat exchanger coils and evaporator coils, requiring periodic cleaning or vacuuming to keep them running efficiently. Heat pump dryers do not vent, so they can collect moisture within the dryer. This could lead to mold.
