What's The Job Market For Heat Pump Dryers Professionals?
Heat Pump Dryers Save Energy and Eliminate Potential Fire Hazards

Conventional dryers heat the air using electric resistance or gas combustion and blow it over tumbling clothes and vent the warm, humid air outside. Heat pump dryers do not require vents. This reduces energy consumption and eliminates potential fire hazards caused by lint accumulation within the ducts.

They also use lower temperatures and are more gentle on clothes, so they may take longer to dry than traditional machines. Learn more about these ventless washing machines from Aztec Appliance.

Efficiency

A heat pump dryer can save you a significant amount of money annually on your electric bill. According to Energy Star, it uses up to 28 percent less energy than a conventional clothes dryer. It may not seem like much, but if you do 20 loads of laundry a week in Massachusetts where electricity prices are among the highest in the country, you will save hundreds of dollars over a 12 year lifespan.

A heat pump dryer is similar to a dehumidifier. The heat pump dryer starts with heated air that is then sent through coils to warm it even more. During this process the hot air draws moisture from the clothing and then into the heat exchanger where it's condensed. It drips into a pan that can be manually empty or connected to drain tubes. The moist, cool air then flows back over the condenser coils until it is then heated and the cycle starts again.

They don't require an exhaust vent. They can be used in places where a conventional dryer would not be able to fit. They are also quieter and more versatile and are ideal for apartments or other areas with small space. They are also safer than dryers that have vents, which could be a fire hazard if not maintained regularly.

They take longer to dry your laundry due to the fact that they operate at lower temperatures. Additionally, because they work as a dehumidifier and generate plenty of water during drying, it's important to clean your heat pump dryer frequently. This is especially true in the case of damp clothes or you reside in a humid region. It is possible to do this by regularly checking and cleaning the lint screens and the condenser coils. It is also recommended to clean the drain tube occasionally. The evaporator coil is susceptible to bacteria and mold, but regular cleaning should keep it in good condition.

Condensation

The traditional method of drying clothes involves a fan blowing hot air over the laundry that is tumbling, then venting that warm, humid air out. This method uses a lot energy and requires a vented outside space to vent the venting. Heat pump dryers, also known 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 run the machine, then condense the moisture that results into water that drains out the bottom of the drum. They are smaller than vented models and can be installed in a laundry room or attic.

Though widely used in Europe and Japan, heat pump dryers are new to the American market. They are now available in sizes to fit most home laundry rooms and provide significant energy savings. Since they don't draw outdoor air they don't require you to clean your venting system or fix any issues that might arise.

The heat pump dryers function like the refrigeration system of refrigerators, with a compressor that pressurizes refrigerant within one set of coils to release heat. They also have an evaporator set of coils that absorb heat from the air that passes through them. The refrigerant that is heated circulates through another set of coils to condense humid air. The refrigerant that has been cooled is then pumped back into the first coils, and is heated.

Heat pump dryers require maintenance just as other dryers with electric motors to ensure their performance is at its best. Lint can build up on filters and evaporator coils. It is crucial to clean these frequently to prevent excessive wear. sites use refrigerants that have high GWP (Global Warming Potential) which means that they need to be recycled properly also.

Another drawback to consider is the fact that heat pump dryers generally take longer than vented ones to finish a load. That's because their maximum temperature--about 120degF, is lower than electric and gas resistance dryers. Therefore, they're required to tumble for an additional time before they're completely dry.

Lint Screens

The dryers of a heat pump come with a lint trap and venting system which need to be regularly cleaned. A clogged dryer vent can increase drying time and pose an fire risk. A vented dryer's exhaust can reach temperatures that are high enough to ignite volatile oils and chemical on clothes.

The vent system in a heat pump requires a dehumidifier to remove moisture from the air prior to it leaves the dryer. A dehumidifier can also reduce energy costs by lowering temperature of the hot water that is used to heat the air.


The lint screen in a heat pump dryer is softer than the conventional dryers, so it requires cleaning more often. The lint trap inside the door opening is also a good place for lint accumulation, and it should be checked and removed regularly.

Heat pump models come with a heated drum, which means the inside of the machine must be kept clear of lint and residue from dryer or fabric softener sheets. The heated drum walls may also need to be cleaned and inspected regularly, as they could need to be changed, according to the user's guide.

According to the U.S. Fire Administration, the accumulation of lint in the dryer's exhaust pipe isn't just an inconvenience. It's also an ignition source that can cause around 2,900 house fires each year. Clean the dryer's lint exhaust the hose every year using a wire brush or employ a leaf blower from the exterior to eliminate lint from inside of the hose, as this Today's Homeowner how-to video explains. It's safer to do this from outside, so that you can avoid getting lint in your face. If you're unsure of your ability to clean the duct, get an expert to do it for you.

If you don't feel air moving through the vent of your dryer outside, or if your dryer is taking longer to dry than usual, there could be an obstruction of lint deeper in the vent. Choose a day of the year to clean your vent system--Labor Day, the beginning of spring or the beginning or end of daylight saving time. Stick to it.

Installation

Modern dryers that are electric are among the best conveniences for homeowners. However, choosing the right dryer is important for those who want to cut down on their energy bills and also have a positive effect on the environment. For many people, heat pump dryers are a great choice. Unlike traditional vented dryers that make use of gas or electricity to heat air and blow dry, hot air into the drum to remove moisture in the air, heat pump dryers reuse the same air over and over 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.

Because heat pump dryers do not require venting outside, they don't require any ducting or chimney and can be placed in 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 over the garage) and even for additions. They are often better than traditional vented models since they are Energy STAR certified.

Heat pump dryers can operated on standard 120-volt 15-amp circuits. This is a huge advantage for older homes with older wiring and can save money on installation.

However the fact that heat pump dryers are less powerful than other dryers means they take longer to complete the cycle. And because they don't have the back-and-forth movement of conventional dryers, large objects such as sheets and towels may wad up into a laundry sausage that's difficult to unravel. Some manufacturers attempt to resolve this issue by changing the tumble cycle for brief intervals of time during a cycle.

They also require more maintenance than other dryers. Lint can build up on the heat exchanger and evaporator coils, requiring professional cleaning or periodic vacuuming to keep them operating efficiently. Because dryers with heat pumps don't vent, they may also accumulate moisture inside the dryer, which can cause mold.
