SRSwirl: When the Duomatics were Bendix and 36" wide the electric drying models were always condenser type. Only when they went to the 27" Philco machines was there one TOL vented electric drying model offered.
Louis and others in markets where they are offered can maybe confirm this and perhaps explain this, but I have read that even the Miele 220 volt (naturally) combo is a slow drying machine. In the US, the fastest drying condenser combos, like the Bendix design had a good, strong air circulator to move the air in its circuit over the heater, through the clothes, through the condenser and then back over the heater. Westinghouse and Maytag are two that shared this feature, but they did not start drying with clothes that were spun to where you could not wring water out of them.
There was a 24" European condensing combo offered for sale by a dealer on eBay for a while. They claimed that the 220 volt machine offered not only a higher wattage heater, but also a more powerful air curculator to speed up the drying. I never saw times so I don't know how much the drying performance was improved. I think production on them stopped, but the guys who sold them really seemed to believe that the model they sold was the best available and offered comparisons to other 115 and 220 volt combos.
