When I purchased a new washing machine I was informed that all machines are
now cold fill only and that was the most economic way of filling
I have hot water available from my boiler and have been used to using that.
that is more economic than heating up cold water from the start?
Am I right?
Depends on the length of the pipe run from the boiler to the WM.
A solenoid on the WM opened to allow hot water in to a certain level, then
shut off. Very often this just drew cold water from the pipe and the
machine filled & shut off before the hot ever reached it.
If the boiler were right next to the WM it would make more sense, but most
aren't. Also, washing is done at lower temperatures these days, often lower
than the water from the boiler.
