Vented clothes dryers in many metrics will beat any sort of condenser including heat pump.
Main argument some have against vented dryers is they pull mechanically heated or cooled air out of a home and exhaust it outdoors after use. That may be true but for many households there are good parts of year when they are not using heating or air conditioning. All dryers are more efficient when more moisture has been extracted from laundry via spin drying. Basically lower the residual moisture content of a wash load leads to faster drying times using less energy. wiki.zero-emissions.at/index.phpQ... www.whitegoodshelp.co.uk/... Laws of diminishing returns does kick in at some point however. Biggest gains come at going from 800/900 rpm final speed to 1100/1200. More still at 1400 or perhaps 1600 rpms, but things level off afterwards (say 1800 rpms). In battle between traditional condenser dryers versus heat pump latter have an edge energy. Latter doesn't rely upon differences between high heat and ambient temps to cause condensation thus can operate at lower temps www.aeg.co.uk/support/sup.... | ||

Another interesting tidbit is that laundry rinsed in warm water dries faster and uses less energy than cold. This is one reason why commercial/industrial laundries rinse in warm water, not cold.
Back during 1970's energy crisis when there was a heat on against washing machines offering warm rinses, Consumer Reports and others basically said "yes, cold rinsing does increase drying costs, but countered against cost and energy used to heat water better to go with cold water". | ||

This load of towels spun at 1,200 rpm consumed 0.89 kWh. That being said: yeah, replacing something just to save energy doesn't always make sense.
