25 Shocking Facts About Heat Pump Dryers

Heat Pump Dryers Save Energy and Eliminate Potential Fire Hazards

Conventional dryers use electrical resistance or gas combustion to heat the air, then blow it over the clothes. The warm, moist air is then vented outside. Heat pump dryers don't require vents. This reduces energy consumption and prevents fire hazards caused by lint accumulation in the ducts.

They also have lower temperatures and are more gentle on clothing, which means they might take longer to dry than traditional machines. Aztec Appliance has more information about these ventless washing machines.

Efficiency

You can save a lot of money on your electricity bill by using the heat pump dryer. It consumes up to 28 percent less energy than a traditional dryer according to Energy Star. It may seem like a lot but if you wash 20 loads of laundry a week in Massachusetts where electricity prices are among the highest in the country and you can save hundreds of dollars over the course of 12 years.

The way a heat-pump dryer functions is similar to that of a dehumidifier. It starts with air that's heated by a compressor, and is then passed through a different set of coils to warm it more. In this process, the hot air draws moisture from the clothing and into the heat exchanger, where it becomes condensed. It then drips into a empty pan or tube that can be connected to drain it. The moist, cooled air is then circulated back over the coils of the condenser to be heated.

Heat pump dryers don't require an exhaust vent, so they can be used in areas that would not be able to accommodate a conventional dryer. They are also more efficient and quieter which makes them suitable for apartment spaces and other rooms that have small space. They are also safer than dryers that have vents, which can be a fire hazard if not cleaned regularly.

However, as they operate at lower temperatures than conventional dryers, it will take longer for your laundry to dry when using the help of a heat pump dryer. It is also essential to clean the dryer on a regular basis since it functions as a dehumidifier, and produces a lot of moisture during the drying process. This is particularly important when you live in a humid environment or if your clothes are soaked with a lot of moisture trapped in the dryer. It is possible to do this by regularly inspecting and cleaning the lint screens as well as the condenser coils. Also, you should clean the drain tube regularly. Regular cleaning will keep the evaporator coil in good condition.

Condensation

The traditional method of drying clothes is to use fans to blow hot air on the clothes. The air is then vented to the outside. This approach uses a lot of energy and requires access to an outdoor space that is vented for venting. Heat pump dryers, also referred to as ventless drying machines, recycle the air. They heat the air that is coming in by reusing some of the energy required to power the machine. They then condense the resulting moisture into water that drains from the bottom of the dryer drum. They are also smaller than vented models, and can be placed in a laundry room or attic.

Heat pump dryers, though popular in Europe and Japan are relatively new to the American market. These dryers are now available in sizes to accommodate the majority of laundry rooms in homes and can provide significant energy savings. Since they don't exhaust indoor air outdoors, you won't need to clean your venting system or deal with any potential problems.

The heat pump dryers are similar to the refrigeration system of a refrigerator. They feature a compressor which pressurizes refrigerant into one set of coils, which releases heat. The evaporator coils soak up the heat from the air that passes through. The heated refrigerant circulates through another set of coils to condense humid air. The cool refrigerant flows back into the original set of coils and is heated to repeat the process.

The heat pump dryers require maintenance as other dryers with electric motors to ensure their performance is at its best. Lint can build up on filters and the evaporator coils. It is crucial to clean these regularly to avoid excessive wear. Additionally, they utilize refrigerants with high GWP (Global Warming Potential), so those need to be properly recycled too.

Another drawback to consider is the fact that heat pump dryers usually take longer than vented dryers to complete a load. This is because their maximum temperature, which is around 120degF, is lower than gas and electric resistance dryers, so they're required to tumble a little longer before they're dry.

Lint Screens

Heat pump dryers have venting and lint trap system that needs to be cleaned on a regular basis. A clogged dryer vent can prolong drying times and create an fire risk. A vented dryer's exhaust can reach temperatures that are sufficient to ignite volatile oils and chemical on clothing.

A heat pump venting system requires an air dehumidifier to eliminate moisture prior to the air exits the dryer. A dehumidifier will also help you save energy by lowering the temperature at which the hot water is heated to warm the air.

The lint filter in a dryer with a heat pump is much finer and must be cleaned more frequently than the one in the conventional dryer. The lint trap that is located in the door opening is also an ideal spot for lint accumulation, and it should be checked and removed regularly.

Heat pump models come with a heated drum, which means that the inside of the machine has to be kept free of lint and residues from fabric softener or dryer sheets. The heated drum walls may be required to be cleaned and inspected periodically, as they might require to be changed, as indicated by the user's guide.

Lint buildup in the dryer's exhaust hoses isn't only a nuisance, it's also a major danger to fire and can cause an average of 2900 house fires every year according to the U.S. Fire Administration. As explained in this Today's home owner video, you can clean the lint-exhaust pipe of your dryer using the help of a wirebrush or leaf blower. This is safer to do from the outside since you won't get lint on your face. If you're not sure that you can clean the ducts, you should hire a professional.

If you don't feel air moving through the vent of your dryer outside, or when your dryer takes longer to dry than usual it could be due to a lint blockage deeper in the duct. Pick a day in the year to clean your vents - Labor Day, the first day of spring, or the day that marks the beginning or the end of daylight saving time--and stick to it.

Installation

Drying laundry in a modern electric dryer is one of the most important conveniences that homeowners have access to. But picking Recommended Web site is crucial for those who want to cut down on their energy bills and make a positive impact on the environment. For many people, heat pump dryers are the best choice. Contrary to traditional vented dryers that use electricity or gas combustion to heat air and then blow the hot, dry air into the drum to remove moisture in the air, heat pump dryers reuse the same air repeatedly and pull the moist air from the clothes and cooling it, allowing it to return to the laundry room, where it can be used again.

Heat pump dryers don't require ducting, chimneys or chimneys to vent outside. They can be put in inside small spaces like laundry closets. This makes them ideal for small homes, accessory dwelling units (such as a laundry room in the basement or an apartment above the garage) and even additions. And because the energy STAR label is a reliable quality mark of energy efficiency dryers with heat pumps are typically more efficient than traditional vented models.

Heat pump dryers can operated 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.

Heat pump dryers have a lower power than other dryers, and therefore take longer to complete a cycle. They also don't have the back-and-forth movement of conventional dryers, large objects like towels and sheets can become a laundry sausage that is difficult to unravel. Some manufacturers attempt to address this issue by reversing the tumble cycle for short periods of time during the course of a cycle.

In addition, heat pump dryers need more regular maintenance than other dryers. Lint can build up on the heat exchanger coils as well as the evaporator coils, and require regular cleaning or vacuuming to ensure they are running at a high efficiency. Since dryers with heat pumps do not vent, they could also gather moisture inside the dryer, causing mold.
