The Ultimate Cheat Sheet For Heat Pump Dryers
Heat Pump Dryers Save Energy and Eliminate Potential Fire Hazards

Conventional dryers heat air with gas or electric resistance, blow it over tumbling clothes and vent the warm, moist air outside. Heat pump dryers don't require vents, which help save energy and reduce fire hazards due to lint accumulation in the vents.

They also have lower temperatures and are gentler on clothing, so they might take longer to dry than traditional machines. Learn more about these ventless laundry machines from Aztec Appliance.

Efficiency

You can save lots of money on your electricity bill by using a heat pump dryer. According to Energy Star, it uses up to 28 percent less energy than a conventional clothes dryer. It might not seem like much, but if you do 20 loads of laundry each week in Massachusetts where electricity costs are among the highest in the nation, you will save hundreds of dollars over the course of 12 years.

The way that a heat pump dryer operates is similar to dehumidifiers. The heat pump dryer begins with heated air, which is then sent through coils to heat it further. During this process the hot air pulls moisture from the clothing into the heat exchanger where it is condensed. It drips into a pot that can be manually emptied or connected to drain tubes. The cooled, moist air then flows back over the condenser coils to be then heated and the cycle starts again.

They don't require an exhaust vent, so they can be installed in places that aren't able to be able to accommodate a conventional dryer. They are also more quiet and flexible and are ideal for apartments or other areas with little space. They are also safer than dryers that have vents. Vents can cause fires when they aren't cleaned regularly.

However, because they operate at lower temperatures than conventional dryers, it takes longer for your laundry to dry using the help of a heat pump dryer. In addition, since they function similar to a dehumidifier, and produce plenty of water during the drying process, it's important to clean your heat pump dryer regularly. That's especially true when you live in a humid environment or if your clothes have lots of moisture in the dryer. You can accomplish this by checking and cleaning the lint screens and the condenser coils. You should also clean out the drain tube every now and then. Regular cleaning will keep the evaporator coil in good condition.

Condensation

The traditional way to dry clothes is by using 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 known as ventless dryers--recycle that air instead. They heat the incoming air by reusing some of the energy required to run the machine. They then condense the moisture that results into water that drains from the bottom of the drum. They are also smaller than vented models and can be put in an attic or laundry room.

Heat pump dryers, though popular in Europe and Japan are relatively new on the American market. They're now available in sizes that would fit into most home laundry rooms and offer significant energy savings and other climate benefits. Since they don't draw outdoor air, you won't need to clean your venting system or fix any potential problems.

The heat pump dryers are similar to the refrigeration system in a refrigerator. They have an compressor that presses refrigerant into one set of coils, which releases heat. The evaporator coils absorb warmth from air passing through. The heated refrigerant circulates in the second set of coils to condense humid air. The refrigerant that is cooled is then pumped back into the first coils, where it is heated.

As with other electric dryers the heat pump dryer requires regular maintenance to ensure its energy efficiency is at its peak. Lint builds up on the filters, and on the evaporator and condenser coils. It is crucial to clean them often to prevent excessive wear. They also utilize refrigerants with high GWP or Global Warming Potential. They need to be recycled.

Heat pump dryers are slower than vented dryers in drying a load. This is because the maximum temperature of heat pump dryers is lower, at around 120 degrees Fahrenheit. This means that they'll need to tumble a little more time before they are completely dry.

Lint Screens

Heat pump dryers are equipped with a lint filter and venting system that need to be cleaned regularly. A blocked vent can dramatically extend drying times, and is a fire hazard. The exhaust of a vented dryer can reach temperatures high enough to spark volatile chemicals and oils on clothes.

The vent system of a heat pump requires a dehumidifier in order to remove moisture from the air before it leaves the dryer. A dehumidifier also helps 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 requires cleaning more frequently than the one in the conventional dryer. The lint trap that is located in the door's opening is an ideal spot for lint to accumulate, and it should be cleaned and cleaned regularly.

The models that have heat pump also have a heated drum wall which means that the interior of the dryer has to be free of lint, fabric softener and dryer sheet residue. The heated drum walls require regular cleaning and inspection, as they could require to be replaced as specified in the user's manual.

According to the U.S. Fire Administration, the accumulation of lint in the dryer's exhaust pipe is more than just an inconvenience. It's also a fire hazard that causes around 2,900 house fires each year. As you can see in this Today's home owner video cleaning the lint-exhaust pipe of your dryer using either a wirebrush or a leaf blower. It's safer to do this from outside, as you can avoid getting lint on your eyes. If you're unsure of your ability to clean the duct, you can hire a professional to do 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 normal it could be due to a lint blockage deeper inside the vent. Choose a specific day in the year to clean the vent system - Labor Day, the beginning of spring, or the closing or the beginning of daylight saving time - and adhere to it.


Installation

Modern dryers that are electric are among the best conveniences for homeowners. But choosing the right dryer is also an important choice for those looking to reduce their energy costs and make a a positive impact on the environment. For many these reasons, heat pump dryers are a great choice. They are different from vented dryers like traditional ones, which utilize gas combustion or electricity for heating air, and then blowing the hot dried air into the drum to eliminate moisture. They reuse the air, removing the humid air and cooling it, allowing it to be returned to the laundry room so that it can again be used.

They do not require chimneys, ducting or a chimney to vent outside. They can be installed within small spaces, such as laundry closets. This makes them perfect for tiny homes and 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 reputable indicator of energy efficiency, heat pump dryers are often more efficient than vented models that are more traditional.

heat pump tumble dryer to the majority of dryers for clothing that require a separate circuit, most heat pump dryers are made to operate on standard 120-volt, 15-amp electrical circuits. This is a benefit for older homes with older wiring and can save you money on installation.

They have lower power compared to other dryers, which means they take longer to complete a cycle. And because they don't have the back-andforth motion that is typical of dryers, large objects such as sheets and towels could end up in laundry sausages that are hard to unwind. Some manufacturers attempt to solve this issue by turning off 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, which require periodic cleaning or vacuuming to keep them running efficiently. Since dryers that use heat pumps do not vent, they could also accumulate moisture on the inside of the dryer, leading to mold.
