Heat-pump vs vented tumble dryer: which is cheaper to own?
Tumble dryers are the clearest case where the sticker lies: the cheap one costs the most. The difference is energy, and over years of laundry it dwarfs the price gap. Here is how the two really compare.
- Far lower energy use per cycle — the whole point of the design
- Fluff filters to clean every cycle and a condenser to clean periodically
- Longer cycle times, but at much lower power
- Generally long-lived with less heat stress on parts
- Much higher energy use per cycle — the hidden cost that adds up fast
- A vent hose or, on condensers, a water tank to empty
- Shorter, hotter cycles that stress fabrics and parts more
- Simple and cheap to buy, but expensive to feed

For anyone who dries laundry regularly, a heat-pump dryer usually wins the true cost of ownership comfortably: the higher purchase price is recovered by the much lower energy use, and the more you dry, the faster it pays back. A vented or condenser dryer only comes out ahead if you dry very rarely, or need the lowest possible upfront cost and cannot spread it — the running cost never catches you if you barely use it.

Common questions
Significantly — using far less energy per cycle is the entire point of the design. Over regular use the energy saving is large, which is why a heat-pump dryer usually wins the true cost of ownership despite costing more to buy.
Because the cost is in the energy, not the sticker. A cheap vented or condenser dryer uses far more power per cycle, so over years of drying it can cost more to own than a pricier heat-pump model. The box price hides the running cost.
Usually yes — cycles are longer because they dry at a lower temperature. That gentler heat is also easier on fabrics and on the machine, and it is what delivers the much lower energy use, so the longer time is the trade for the lower running cost.
