If you’re in the market for a new clothes dryer, you might want to consider a heat pump dryer as an alternative to a traditional vented one. It can be a quick and easy step on the road to full home electrification.
Even if your current dryer is already powered by electricity, the higher efficiency of a heat pump dryer is a win for the environment. And if you currently dry your wet clothes with a gas-powered dryer, then switching to a heat pump dryer is an even bigger win for the environment.
In this guide, we’ll explore the technology and benefits of heat pump dryers in comparison to traditional vented dryers, as well as their energy efficiency potential and environmental benefit.
We’ll help you to weigh up-front costs against long-term savings while considering maintenance requirements specific to heat pump dryers. To help you make an informed choice, we’ll also review some popular models from leading brands like Miele and Whirlpool.
Finally, our guide will help you decide if a heat pump dryer is right for your home based on your current laundry needs and environmental goals.
Heat Pump Dryer Technology
A heat pump dryer uses the same technology as air conditioners and refrigerators to dry clothes, making it energy-efficient and ventless. They’re powered by electricity, rather than gas, and they’re much more efficient than traditional dryers.
How a Heat Pump Dryer Works
- The dryer pulls in ambient air from the room.
- A heat exchanger warms up the air using refrigerant gas, which absorbs heat from the surroundings as it evaporates.
- The heated air passes through your damp laundry, absorbing moisture and drying your clothes.
- The moist warm air goes back into another part of the heat exchanger where it cools down by releasing its absorbed heat back into refrigerant gas (which now condenses).
- This process causes water droplets to form on cold surfaces within the machine, which are collected in a tray or pumped out via a drain hose.
Heat Pump Dryers vs Vented Dryers
Heat pump clothes dryers are more energy-efficient than traditional vented models, using up to 60% less electricity according to electricrate.com.
The fact that they also operate exclusively on electricity, while traditional dryers can be either gas powered or electric, means that heat pump dryers are an economically and environmentally sound choice, with potential savings on electricity bills of up to $588 over their 10-year average lifespan.
Potential savings on electricity bills
Switching to a heat pump dryer could potentially cut your laundry drying budget by 60%, saving you hundreds of dollars over time.
According to EnergySage.com the average clothes dryer that is used four times a week consumes 624 kWh of electricity a year. Where I live in Massachusetts, electricity from the local utility company currently costs a whopping 40 cents per kWh (although much cheaper if you go solar).
So if you currently spend $250 per year on drying clothes (40 cents x 624 kWh) and you can save 60% by switching to a heat pump dryer, that could be $150 in savings per year. Spread out over the expected lifespan of the dryer, this would more than make up doe any higher upfront cost.
Swapping out an outdated appliance with a modern, ENERGY STAR certified heat pump dryer can help reduce the amount of greenhouse gases discharged into the atmosphere and aid in combating climate change.
Upgrading from an older inefficient model to an ENERGY STAR certified one can prevent more than six tons of CO2 emissions over the appliance’s lifetime.
Additional Benefits of Heat Pump Dryers
Besides being more energy-efficient than conventional models, heat-pump dryers offer other benefits such as lower operating temperatures which are safer for clothes, smaller capacities suitable for certain households’ needs, and impressive safety credentials due to non-flammable/non-ozone depleting refrigerants instead of natural gas or propane fuel sources.
Gentle Drying Cycle
The lower operating temperatures in heat pump dryers not only save energy but also help preserve the quality of your clothes, preventing fabric damage due to high temperatures, leading to shrinking and color fading.
You Can Put Them Anywhere
Because there is no need for an external vent, you are not required to place a heat pump dryer against an external wall. In fact, you can place it in any room you like, and they’re ideal for apartments for this very reason. They’re also smaller than most traditional dryers so they can often be hidden away in a closet.
Safety Features Minimizing Fire Risks
- No External Vents: Heat pump dryers eliminate potential fire hazards associated with lint buildup in ducts.
- Eco-Friendly Refrigerants: The use of non-flammable and environmentally friendly refrigerants reduces the risk of fires caused by flammable gases found in some traditional gas-powered appliances.
- Automatic Shut-Off: Many heat pump dryers come with built-in sensors that detect when the clothes are dry and automatically turn off the machine, preventing overheating and potential fire hazards.
It’s essential to follow proper maintenance guidelines for your dryer. Check out this National Fire Protection Association guide on how to prevent dryer fires in your home.
Drawbacks of Heat Pump Dryers
Before you jump on the heat pump dryer bandwagon, there are a few things you should know.
- Higher Upfront Costs: These dryers can be pricier than traditional vented models, so make sure you’re willing to invest in the long-term energy savings.
- More Maintenance: You’ll need to clean the filters and condenser units regularly to avoid lint build-up that can affect performance.
- Longer Drying Cycle: If you’re in a hurry, a heat pump dryer might not be the best choice for you.
Weigh the advantages and disadvantages carefully before making a decision, selecting a model that best fits your laundry needs.
Is a Heat Pump Dryer Right for You?
Before investing in a heat pump dryer, consider your laundry habits, environmental impact goals, and budget constraints
Assessing your drying needs
Think about how often you do laundry and the types of clothes you typically dry to determine if a heat pump dryer is suitable for your needs.
If you prioritize speed over energy efficiency and gentler drying, the longer drying cycle of heat pump dryers may become an issue.
If you’re ready to wait a bit and want to save on energy bills while shrinking your environmental impact, a heat pump dryer may be worth exploring.
FAQs in Relation to Heat Pump Dryer
What are the pros and cons of a heat pump dryer?
- Pros: Energy-efficient operation reduces electricity bills; environmentally friendly; gentle on clothes; safety features minimize fire risks.
- Cons: Higher upfront cost; longer drying times; possible maintenance needs.
Is a heat pump dryer worth the extra upfront cost?
