Guidance
Heat-pump dryers in practice
HP dryers use ~50% less electricity than vented resistance dryers, are ventless (so no exterior wall penetration needed), and operate at lower temperatures (gentler on fabrics). Tradeoffs: cycle time is ~25% longer, and the condensate needs to drain (either to a drain line or a removable tank).
Note
Ventless HP dryers can be installed in apartments and tight spaces with no exterior wall — opens up laundry placement options. Most newer models (Whirlpool, LG, Miele, GE) qualify for the ENERGY STAR Most Efficient list.
