Declared/published performance of the 847 A Class machine is:
With test conditions as stipulated in EN 61121- European standard.
Dry cotton load = 5kg, Room temperature 20C
Energy to dry the above load in A class mode = 2.5 kWh
Wetted condition of test load = 70% so 3.5kg of water or 7.7 lbs
Time to dry the test load under these conditions = 8hrs.

... 2.5kWhx3412/7.7lb = 1108 Btu/lb.

Machine is a Splendide 2000, vented model...

... it filled once and spent about 45 minutes washing. In this mode
it spends about 12 seconds turning one way, rests for 5, reverses.

The Philips machine I used in France rested about 5 minutes.

Next it enters spin mode, perhaps 10 minutes of various tumbling, spin
speed ramp-up and pumping. Power consumption tops out at about 400W
until it goes into scary-spin mode, about 500W steady for another 10 minutes.

Scary-spin mode sounds like fun. UK machines are rated by rpm.

70 minutes to this point, .21kWh. Removed clothes and weighed, about
1.5lb gain.

Replaced clothes for drying, 700W steady for 20 minutes. Vent air is
very gentle flow, barely warmer than room air. Last 10 minutes is by
design tumbling with heat off. Consumption down to about 100W when
drum is turning, about 150W with pump combined.

Total time 1:45. Total consumption .45kWh. No detectable weight loss
since spinning, but my scale was too useless to tell.

Hmmm. The 5 pounds of clothes still weighed 6.5 pounds after "drying"?

The energy consumption was low, but this experiment seems inconclusive.
