Hi NT,
The reason would be to save money and energy by heating the water by
gas rather then electricity.
Well, with gas you've got boiler flue losses and pipe heat losses. OTOH
the gas that makes the leccy probably uses even more energy.
I don't understand why you think the result would be a poorer wash. So
long as the water in the machine during the wash phase is at the
temperature required by the powder (say 40°C) it doesn't matter how
you heat it.
Heating from cold to target temp in the washtub gives the washpowder
more time in the tub, as the wash timer doesnt start ticking till its
heated. Second it gives the powder the chance to work at different
temps, instead of all at the same temp. This is especially important
with bio powders, fill the tub with 60C water and you get no bio
action, fill it at 20 and heat it, and it will work in a different way
at the different temp bands it goes thru, giving a better wash. So
you've got 2 ways in which you'll see poorer results.
The 3rd problem is that the hot fill water will be too hot for the
clothes in many cases.
But really far more important is just that its a waste of human time
and energy.
