5 Laws That Anyone Working In Heat Pump Dryers Should Know
Heat Pump Dryers Save Energy and Eliminate Potential Fire Hazards

Conventional dryers heat air using gas or electric resistance and blow it over clothes that are tumbling, and then release the warm, moist air outside. Heat pump dryers don't require vents. This reduces energy consumption and reduces the risk of fire caused by lint accumulation in the vents.

These machines also operate at lower temperatures and are more gentle on clothing. They may take longer to finish drying 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 every year on your electricity bill. According to Energy Star, it uses up to 28 percent less energy than a conventional clothes dryer. It might not sound like much however, if you are doing 20 loads of laundry per week in Massachusetts where electricity costs are among the highest in the nation, you will save hundreds of dollars over the course of a 12 year lifespan.

The way a heat pump dryer operates is similar to that of dehumidifiers. The heat pump dryer begins with heated air that is then sent through coils to warm it further. In this process, the heated air draws moisture from the clothing and then into the heat exchanger where it's condensed. It drips out into an empty pan or tube that can be connected to drain it. The cool, moist air is then circulated back through the coils of the condenser, to be heated.

They don't require an exhaust vent. They can therefore be installed in places where a traditional dryer would not be able to fit. They are also more silent and versatile and are ideal for apartments or other areas with limited space. They are also more secure than dryers with vents. Vents can spark fires when they aren't cleaned regularly.

However, because they operate at lower temperatures than conventional dryers, it will take longer for your laundry to dry when using a heat pump dryer. Additionally, because they work much like a dehumidifier and release a lot of water during drying it is essential to clean your heat pump dryer regularly. This is especially important when your clothes are damp or you reside in a humid region. You can do this by regularly inspecting and cleaning the lint screens and the condenser coils. You should also clean the drain tube regularly. Regular cleaning will keep the evaporator in good shape.

Condensation

The traditional method of drying clothes involves an air conditioner 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 a vented outside space for the ducting. Heat pump dryers, also known as ventless dryers re-use the air instead. They heat the incoming air by reusing a portion of the energy that goes to power the machine. They 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 an attic or laundry room.

The dryers with heat pumps, while popular in Europe and Japan are relatively new on the American market. These dryers are now available in sizes to fit in most laundry rooms and offer significant energy savings. And because they don't exhaust indoor air to the outdoors, you don't have to clean your venting system periodically or deal with the potential issues that can arise with a dirty one.

Heat pump dryers are similar to the refrigeration system in a refrigerator. They feature an air compressor that pressurizes refrigerant through one coil, and then releases heat. The evaporator coils absorb the heat from the air that passes through. The heated refrigerant circulates in the second set of coils to condense moist air. The refrigerant that has been cooled is then pumped back into first coils, and is heated.

Like other dryers with electric motors, a heat pump dryer requires maintenance to ensure its energy efficiency is at peak performance. Lint collects on the filters, and on the condenser and evaporator coils. It is crucial to clean them often to avoid excessive wear. And they use refrigerants with high GWP (Global Warming Potential) which means that they need to be recycled properly as well.

The heat pump dryers take longer than vented dryers to dry a load. It's because the maximum temperature of heat pump dryers is lower, at 120 degrees Fahrenheit. This means that they need to tumble a more time before they are completely dry.

Lint Screens

Heat pump dryers have a lint filter and venting system that must be cleaned on a regular basis. A clogged dryer vent can increase drying time and pose the risk of fire. Vents for dryers that are vented can reach temperatures that are high enough to ignite volatile oils and chemical on clothes.

A heat pump vent system requires a dehumidifier to remove moisture before the air exits the dryer. Dehumidifiers can also cut down on energy costs by lowering temperature of the incoming hot water used to heat the air.

The lint screen in the heat pump dryer is more fine than conventional dryers, which is why it requires cleaning more often. The lint screen inside the door opening can also collect lint. It should be cleaned often.

Heat pump models include a heated drum which means the interior of the machine needs to be free of residue and lint from fabric softener or dryer sheets. The heated drum walls may also require cleaning and inspected on a regular basis, since they could need to be changed, according to the user's manual.

Lint buildup in the dryer's exhaust hose is not just a nuisance; it's a serious fire hazard that causes an average of 2900 house fires each year, according to the U.S. Fire Administration. As you can see in this Today's homeowner video, you can clean the exhaust hose of your dryer with the help of a wirebrush or leaf blower. It's safer to clean the hose from the outside, so that you can avoid getting lint on your eyes. If you're not sure that you can clean the ducts, you should hire a professional.

If you are unable to feel air moving in the dryer vent, or if you notice that your dryer is taking longer to dry, it could mean that there is a lint obstruction within the vent. Choose site web of the year to clean your vent system--Labor Day, the first day of spring, or the day that marks the beginning or end of daylight saving time. Stick to it.

Installation


Modern electric dryers are among the most useful features for homeowners. But choosing the best dryer is essential for those who wish to reduce their utility costs and also have a positive effect on our environment. Heat pump dryers are an excellent choice for a variety of. Contrary to traditional vented dryers that use electricity or gas combustion to heat air and blow the hot, dry air into the drum to remove moisture and re-use the same air repeatedly, pulling the moist air away from the clothes and cooling it, allowing it return to the laundry room, where it can be used again.

Heat pump dryers do not require chimneys, ducting or chimneys to vent outside. They can be placed inside small spaces like laundry closets. They are perfect for small houses, accessory dwelling units (such a laundry room or apartment above the garage) or 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 is an advantage for older homes with older wiring, and could reduce the cost of installation.

They have lower power than other dryers, so they take longer to complete a cycle. And because they don't have the back-and-forth motion of conventional dryers, large items such as sheets and towels may wad up into laundry sausages that are difficult to remove. Some manufacturers attempt to resolve this issue by changing the tumble cycle for brief intervals of time during the course of a cycle.

Heat pump dryers 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 ensure they are running at a high efficiency. The dryers that use heat pumps do not vent, which means they could accumulate moisture within the dryer. This could lead to mold.
