Cutting the number down

The spin speed of the washer sets the dryer's workload. A faster final spin removes water mechanically instead of thermally, which is far cheaper.
A blocked lint screen or crushed vent hose makes every load run longer at full heat.
Back-to-back loads reuse a drum that is already hot.
