Only one of the three needs a hole in the wall
All three types remove the same moisture from the same wet clothes, they just get rid of it differently. A vented dryer heats air, passes it through the drum, and blows the resulting warm, damp air straight outside through a fixed vent or hose, which is why it has to sit against an external wall or run ducting to one. A condenser dryer keeps that damp air inside the machine instead, running it over a heat exchanger that turns the moisture back into liquid water, collected in a tank you empty or drained straight to plumbing. A heat pump dryer does the same moisture-collecting trick as a condenser, then goes a step further and reuses the heat left behind rather than discarding it, which is also why it's the cheapest of the three to run.
That difference in how the moisture leaves the machine is the whole reason condenser and heat pump dryers exist: neither needs external venting, so both can go in an internal laundry, an apartment, or anywhere there's no wall to punch a hole through, a straightforward install versus a vented dryer's genuine constraint.
What you trade for skipping the vent: cycle time
The trade-off runs the other way on drying itself: a vented dryer's continuous exhaust lets it run hotter and finish a load fastest, a condenser is a little slower, and a heat pump's lower operating temperature, the same trait that saves electricity, is also why its cycles commonly run longest of the three. Skip the external vent and you're trading some cycle time for it, on either of the other two types.
What this costs, state by state
The registry median for each of the three dryer types, run 4 full loads a week, the same worked example our dryer calculator uses, at each state's current reference electricity rate.

The condenser has no real case left once venting isn't the constraint
If venting is the actual constraint, condenser and heat pump are the only two contenders, and here the comparison stops being close. At the registry-median figures our dryer calculator itself uses, a condenser dryer draws 6.79 kWh a load against a heat pump's 2.6, a heat pump needs 62% less electricity for the identical wash, and that's before the purchase price. At matching 8kg capacity, Appliances Online currently lists an 8kg condenser dryer at $816, more than the cheapest 8kg heat pump model on the market, $699 from The Good Guys. A condenser dryer that costs more to buy and more to run than a heat pump doing the identical job, with no venting advantage over it either, is usually not worth choosing on the numbers alone: the reasons left to pick one over a heat pump are a faster cycle time or a lower price against a specific heat pump model on sale, not the running-cost or purchase-price maths in general.
One row in the state table above looks like a misprint and is not: a condenser dryer uses more electricity per load than a vented one. That is the register's own reading, and it is what the mechanism predicts. A vented dryer throws its warm damp air away, wasteful of heat but cheap in electricity. A condenser has to actively cool that same air down to wring the water back out of it, and it pays for the cooling. The reason this has not been the obvious headline before is that the register files combination washer-dryers under clothes dryers and almost all of them land in the condenser band, which pulled the published condenser figure down to a number no machine that only dries has ever drawn.
| Type | Capacity | Cheapest listed |
|---|---|---|
| Vented | 8kg | $385 |
| Heat pump | 8kg | $699 |
| Condenser | 8kg | $816 |
Purchase price only: installation, plumbing a condenser's drain, or ducting a vented dryer to an outside wall can add to any of the three.
If you do have a vent: still cheapest to buy
Against a vented dryer, the calculation is the opposite: vented remains the cheapest to buy by a wide margin ($385 at the same capacity), it's simply the one type that needs somewhere to vent to. Where that's genuinely not available, a heat pump dryer is the type worth budgeting for; where it is, our companion guide on whether a heat pump dryer is worth the extra money has the full payback maths on choosing it anyway.
Common questions
Which dryer type should I actually buy?
A quick rule: if you have somewhere to vent to, buy vented, it's the cheapest of the three to buy, the fastest to finish a load, and cheaper to run than a condenser. If you don't, buy heat pump over condenser, it's cheaper to buy and cheaper to run than a condenser doing the identical job, so condenser rarely wins that contest outright. Budget for a heat pump only if venting genuinely isn't available and running cost matters more than the extra upfront price.
If I already have external venting, is there any reason to skip a vented dryer?
Mainly speed and running cost trading against each other. A vented dryer stays the cheapest of the three to buy and finishes a load fastest, since it doesn't have to slow down to recycle its own heat. A heat pump costs more upfront but uses well under half the electricity per load; our companion guide on whether a heat pump dryer is worth the extra money works out how long that premium takes to earn back if the vent isn't the deciding factor either way.
Is there ever a good reason to buy a condenser dryer anyway?
Mostly on sale pricing or a specific model you already want, not on the running-cost or purchase-price maths in general. A condenser also skips the heat pump's slower, lower-temperature cycle, so if a faster finish matters more than the extra running cost and a hole in the wall still isn't an option, that's the one genuine trade-off left in a condenser's favour.
