How to Properly Use a Heatpump Dryer

Contrary to conventional dryers that use hot air to dry the clothes, heat pump dryers use electricity to transfer water from the fabric to its compressor. The moisture is dehumidified, then heated during the process to produce a low-temperature drying process.

ENERGY STAR lists several 4-cubic-foot heat pump dryer models which are smaller than conventional American standard sized dryers (which typically have a capacity of seven cubic feet). The smaller sizes are less bulky and may qualify for rebates in some states.

Energy Efficiency

A heatpump dryer is renowned for its energy efficiency. It uses the energy of ambient air to dry clothes and it doesn't produce waste heat or venting like conventional dryers do. As a result, heatpump dryers can save homeowners up to $600 in energy costs over the course of the life of the appliance. They also have a lower environmental impact than traditional dryers, due to their use of renewable energy sources.

The energy efficiency of a dryer made by a heatpump is determined by the COP (coefficient of performance) of the system, which is the proportion of its cooling capacity to power consumption. The more COP is higher, the more efficient the heat pump is. This is why dryers with heatpump have a lower kilowatts consumed per hour than regular dryers.

In addition to reducing energy consumption, the lower temperature in the heat pump dryer also reduces drying time by increasing the dehumidification capacity of the system. Jia et al. (1993) tested a combined heat pump and microwave dryer that included a loop thermosyphon for low temperature grain drying. They found that the system consumed less than 2.1 MJ per kg water removed.

Heat pumps can be employed in conjunction with other drying methods to improve energy efficiency. As an example, atmospheric freezing can be coupled with a heating pump to produce an efficient process over vacuum freezing and to create products similar to those produced by vacuum freeze-drying (Bantle and co. 2009).

Many rebate programs provide incentives to purchase dryers with heatpump, even though the initial cost could be higher. For instance, the IRA's Energy Star program provides rebates to homeowners who have cut their energy consumption throughout the home by 35 percent or more. This helps make the upfront cost of a dryer with a heatpump more affordable for families with smaller budgets.

For those looking for the most energy efficiency, a heatpump dryer is a great alternative. It is estimated that it could reduce the energy use of more than 40 percent when compared to a traditional dryer which makes it one of the most efficient ways to dry clothes at home.

Convenience

These dryers, which are relatively new in the United States are gaining popularity because of their energy efficiency and climate benefits. They are also gentler on clothes because they utilize lower temperatures to dry them and moisture sensors help prevent overheating. These features reduce shrinkage and wear on clothing, making them more affordable than traditional electric dryers.

The main feature that distinguishes a heat pump dryer from traditional models is the closed-loop system they employ to recycle air and store moisture during drying. Instead of heating and then dumping hot air and water into the environment through exhaust vents, they employ refrigerant and compressor to continually recycle the same air and capture excess moisture.

This process is similar to a refrigerator in reverse: the compressor heats the air and moves it into a cold evaporator coil, where the water vapor condenses in a pan. Then, the dry air is recirculated into the drum, while the excess moisture is pumped to the drain pan. The hose for condensation drains to your home's sewer line which eliminates the necessity for an exhaust vent in most instances.

The heat pump dryers cut down on the cost of electricity and are also quieter. Some models even have sound-dampening technology to improve your comfort. They are also easier to maintain than traditional dryers. They have fewer parts, and are less likely to break as they don't require vents. They also don't require a gas line as vented dryers, which can be expensive to repair or replace.

The only downside to convenience is that heat pumps dryers tend to take longer to dry than traditional dryers. They operate at lower temperatures and may need to run several times to get the laundry completely dry. However, this is often compensated by reducing electricity consumption and by incorporating energy-efficient features to make up for this delay.

The Miele T1 heat pump dryer, for instance, saves up to 60% of energy consumption and has a lower noise level thanks to its vibration reduction system. It also comes with smart features like EcoDry or PerfectDry that assesses the calcium content of your water to ensure safe and consistent drying. The dryer is Wi-Fi compatible and can be controlled remotely by using a smartphone app.

Easy Installation

A heat pump dryer makes use of a special compressor to move heat from the air to the laundry. It can be put in any place as it doesn't need vents. This makes it an excellent choice for tiny houses and accessory dwelling units (e.g. an apartment above the garage) and even additions. You can stack a heat pump dryer and an washer to reduce space.

The primary drawback of this kind of dryer is that it takes longer to dry the load than the conventional vented dryer. It's less energy-intensive and it doesn't produce any smells. It can also help reduce the amount of laundry you wash, and keep your clothes fresher longer.
