A heat-pump dryer can be worth buying for energy use, installation layout or both. It recirculates heated air and removes moisture without a conventional exhaust vent. The purchase comparison should start with the dryer that would otherwise be bought and the machine drying that will remain in the household.
Published prices and laboratory efficiency guidance are useful starting points, but neither establishes a home’s annual saving. This guide uses LG’s current named-model listings and explicit energy examples. The photographs show laundry equipment and an air-drying routine; they do not identify the machines as the priced model or claim first-hand testing.

The price gap between the white and graphite listings is $350. That difference alone can matter more than several years of energy savings in a low-use household. Confirm the selected model, finish, availability and final checkout amount rather than assuming every finish shares the headline price.
LG separately lists a compatible stacking kit at $55 and a pedestal at $249 on the checked page. Neither should be assumed necessary for every installation, and neither belongs in a base machine price unless selected. Delivery, removal, connection and drainage work require their own inclusion or exclusion in the quote.
The efficiency percentage applies to dryer energy
ENERGY STAR describes heat-pump dryers as capable of at least 28% lower energy use than standard dryers. That is a comparison of drying equipment, not a promise of a 28% reduction in the whole-house bill. A household with little machine drying has less energy to avoid than one drying many loads.
Assume the existing dryer uses 1,000 kWh annually for the laundry that remains. Applying 28% as an illustrative reduction gives 280 kWh avoided and 720 kWh remaining. At EIA’s July 2026 residential benchmark of 18.31 cents per kWh, the avoided charge is $51.27 annually.
An assumed 2,000 kWh baseline would avoid 560 kWh at the same percentage, worth $102.54. Those consumption baselines are assumptions, not ENERGY STAR test values for the LG model. Replace them with measured use or comparable certified energy information for the household’s selected appliances.
The appliance running-cost guide explains why maximum input watts cannot simply be multiplied by every laundry hour. Sensor operation, load size, washer spin and the drying setting affect full-cycle consumption.
The replacement premium gives a more useful payback
When a dryer has failed, the household already needs to buy a replacement. The efficiency investment can be the extra cost over another dryer that fits the installation and laundry requirements. Dividing the entire heat-pump price by savings treats the alternative replacement as free.
For an explicit worksheet, assume a compatible alternative costs $750 before installation. The $1,349 white heat-pump listing has a $599 equipment premium. At the assumed 1,000 kWh baseline and $51.27 annual saving, simple payback is about 11.7 years. With the $999 graphite listing, the assumed premium is $249 and payback about 4.9 years.
The $750 comparator is not a published average or a model recommendation. It demonstrates why an offer, configuration and genuine alternative must be known. At the higher 2,000 kWh baseline, the same $599 premium takes about 5.8 years at the assumed reduction and benchmark rate.
If the existing machine still works, buying a new dryer now is a larger investment than choosing an efficient model during replacement. The appliance repair comparison keeps those two decisions separate. Add repair prospects and expected service needs without inventing a lifespan guarantee.
Ventless still requires power, drainage and clearance
LG’s specification lists the DLHC5502 as 27 inches wide and 32.25 inches deep, with a 52.75-inch depth when the door is open. These dimensions describe the appliance and opening; the required installation space and clearances must also be checked for the planned arrangement.
The specification identifies 240V or 208V electrical requirements. It does not support connecting this model to a household 120V outlet merely because no exhaust vent is needed. A provider should verify the supply, connection and applicable installation requirements rather than infer compatibility from the old dryer’s footprint.
ENERGY STAR explains that removed moisture needs disposal, whether through a collection tank, a hose to an allowed drain or another manufacturer-supported arrangement. Determine who handles that work and whether tank emptying is acceptable in the household’s routine. Ventless does not mean no installation planning.
Laundry habits and maintenance change the value
ENERGY STAR recommends pairing the dryer with a washer that removes more water in its final spin, using sensor controls and maintaining filters. An efficient dryer still has ongoing operating tasks. Check access to its service and cleaning points when considering a closet or stacked setup.
The clothesline comparison addresses loads that can be air-dried. If that routine already avoids half the machine cycles, do not calculate heat-pump savings from the original full workload. The smaller remaining baseline can lengthen the appliance premium’s payback.
Compare the cycles and fabric settings used most often, as well as the household’s tolerance for different drying times. An energy saving cannot establish whether the machine’s capacity, controls or throughput fits the routine. A large drum also does not justify overloading beyond its instructions.
Use the selected model’s installation instructions and qualified electrical or plumbing help where needed. Confirm voltage, connection, drainage and clearances; do not improvise an adapter or drain route to make a quoted price fit.
Add the net equipment premium and required installation differences to the home energy budget. The purchase can be worthwhile for a ventless layout even when electricity payback is long. Keep that practical benefit distinct from cash savings so a reasonable choice does not depend on an exaggerated bill reduction.
Questions people ask
How much does a heat-pump dryer cost?
LG's checked named-model listings show $999–$1,399 across three finishes, with the white model at $1,349. These are promotional equipment prices; delivery, installation, accessories and other models can change the total.
Will the whole electric bill fall by 28%?
The ENERGY STAR comparison concerns dryer energy. Applying 28% to an assumed 1,000 kWh dryer baseline avoids 280 kWh, not 28% of every household load.
Can this ventless model use a normal 120V outlet?
The named LG specification lists 240V or 208V requirements. Ventless refers to exhaust design and does not establish compatibility with a standard 120V supply.
What price belongs in a replacement payback?
When replacement is already necessary, compare the installed premium over another compatible replacement. If the current dryer still works, buying an entire new appliance is a different investment.
