For washing machines with modern detergents and fabrics, most washes
are fairly cool as well, so there is less and less need to fill them
with hot water either.

I stuck an electricity consumption meter on my washing machine at
40C wash.
It used about half a unit heating the water.
So, maybe a saving of 3p/wash if gas heated.
At a wash every couple of days, that's around 5 quid a year.
Not utterly negligable, but non-zero.
Probably more important would be the reduction in time spent heating water
cutting 20 minutes off a cycle.


Sure? How would you differentiate from what the motor uses?

Guess, based on current load with motor+heater in use (some 11.5A, and off
at around 11A)
Probably a little more.
The total used was 0.66 units.
