7 Small Changes That Will Make A Big Difference In Your Heat Pump Dryers
Heat Pump Dryers Save Energy and Eliminate Potential Fire Hazards

Conventional dryers heat air with gas or electric resistance and blow it over clothing that is tumbling and then vent the warm, moist air outside. The dryers that use heat pumps do not require vents. This saves energy and eliminates potential fire hazards caused by lint accumulation within the ducts.

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

Efficiency

A heat pump dryer can save you a substantial amount of money each year on your electricity bill. It uses up to 28% less energy than a traditional clothes dryer according to Energy Star. It may not sound like much, but when your family is doing 20 loads of laundry per week in Massachusetts, where electricity rates are among the highest in the United States, you'll save hundreds over the course of 12 years by using a heat pump dryer.

A heat pump dryer is similar to a dehumidifier. It starts with air which is heated by a compressor, and is then passed through a different set of 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 then drips into a empty pan or a tube that can be connected to drain it. The moist, cooled air is then circulated over the coils of the condenser to be heated.

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 ideal for apartments or other spaces that have small space. They are also safer than dryers with vents. Vents can cause fires if they are not cleaned regularly.

Heat pump dryers take longer to dry your laundry because they operate at lower temperatures. It's also important to clean the dryer on a regular basis because it functions as a dehumidifier and creates lots of moisture during the drying process. This is especially important in the case of damp clothes or you reside in an area that is humid. You can do this regularly by cleaning and checking the lint filter and condenser coils. You should also clean the drain tube periodically. The evaporator coil is susceptible to bacteria and mold, but regular cleaning should keep it in good shape.

Condensation

The most common method of drying clothes is to use a fan to blow hot air onto the clothes. The air is then vented outside. This approach uses lots of energy and requires access to an outdoor space that is vented to vent the ducting. Heat pump dryers, also known as ventless dryers re-use the air instead. They make use of the heat to repurpose energy to power the machine, and then condense it into water that drains from the bottom of the drum. They're also smaller than vented dryers, and can be incorporated into a laundry room or even an attic.

Though widely used in Europe and Japan The heat pump dryers are relatively new to the American market. These dryers are now available in sizes to fit most home laundry rooms and provide significant energy savings. Since they don't vent the indoor air to the outside it isn't necessary to clean out your venting system periodically or deal with the possible issues that could arise with a dirty one.

They function as refrigeration systems in refrigerators with the compressor that presses refrigerant through one set of coils to release heat and an evaporator set of coils that absorb heat from the air passing through them. The refrigerant that is heated circulates through the second set of coils to condense humid air. tumble dryer with heat pump cooled refrigerant is then pumped back into the first coils, where it is reheated.

Like other dryers with electric motors like other dryers, a heat pump requires regular maintenance to keep its energy efficiency at peak performance. Lint builds up on the filters, as well as on the condenser and evaporator coils, and it is essential to clean them frequently to prevent excessive wear. They also use refrigerants that have high GWP (Global Warming Potential) which means that they need to be properly recycled too.

Another drawback to consider is the fact that heat pump dryers usually take longer than vented ones to complete a job. It's because their maximum temperature of 120degF, is lower than gas and electric resistance dryers, which means they're required to tumble for some time before they're completely dry.

Lint Screens


Heat pump dryers come with a lint trap and venting system which need to be cleaned on a regular basis. A blocked dryer vent could 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 chemicals on clothing.

A heat pump's vent system requires a dehumidifier to eliminate moisture from the air prior to it leaves the dryer. A dehumidifier can also help you save energy by lowering the temperature at which hot water is heated to warm the air.

The lint screen in a heat pump dryer is softer than the conventional dryers, so it needs to be cleaned more frequently. The lint screen in the door's opening could collect lint. It is recommended to clean it regularly.

The models that have heat pump also have an insulated drum wall, which means that the interior of the dryer must be kept free of lint, fabric softener and dryer sheet residue. The heated drum walls could also need to be cleaned and inspected on a regular basis, since they might require to be changed, as indicated by the user's manual.

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 your dryer's lint exhaust pipe every year with a wire brush or employ an air blower from the exterior to remove lint from the inside of the hose, as this Today's Homeowner video explains. It's safer to do this from outside, since you will avoid getting lint on your eyes. If you're unsure of your ability to clean the duct, hire an expert to handle it for you.

If you can't sense air flowing through your dryer vent outside or the dryer is taking longer to dry than normal it could be due to a lint blockage deeper in the duct. Pick a day in the year to clean your vent system--Labor Day, the first day of spring, or the day that marks the beginning or the end of daylight saving time. Stick to it.

Installation

Modern electric dryers are one of the most useful features for homeowners. But picking the right dryer is essential for those looking to lower their utility bills and make a positive impact on our environment. For many people, heat pump dryers are an ideal option. They differ from traditional vented dryers, which utilize gas combustion or electricity for heating air, and then blowing the hot, dried air into the drum to remove moisture. They reuse the air, pulling the humid air and cooling it, permitting it to be returned to the laundry area where it can again be used.

Because heat pump dryers don't require venting outside and don't require chimney or ducting and can be put in small spaces, such as laundry closets. They are perfect for small houses, additional dwelling units (such a laundry room or an apartment above the garage) or even additions. Additionally, since the ENERGY STAR label is a reliable quality mark of energy efficiency heat pump dryers are often more efficient than traditional vented models.

In contrast to other types of clothes dryers, which need a dedicated circuit, most heat pump dryers are designed to run on standard 120-volt, 15-amp electrical circuits. This can be an advantage for older homes with older wiring and can reduce the cost of installation.

However the fact that heat pump dryers aren't as powerful than other types of dryers, means they take longer to complete the cycle. Because they don't feature the back-and-forth movement of conventional dryers, large items like towels and sheets can become laundry sausages that are hard to unwind. Some manufacturers attempt to solve this issue by reversing the tumble cycle for short durations during the course of a cycle.

The dryers that use heat pumps also require more maintenance than other dryers. Lint can accumulate on the heat exchanger and evaporator coils, and require professional cleaning or periodic vacuuming to ensure that they function effectively. Since dryers with heat pumps don't vent, they can also accumulate moisture on the inside of the dryer, which can cause mold.
