Actually..
A few hot and cold machines have started to creep back into manufacture.
It is starting to be viewed now that hot and cold fill may actually be more economical.
A lot of us now have instant hot water from the combi boilers, so unlike a hot water tank that would need to be heated up. Instant hot water comes through the boiler and as nine times out of ten, the boilers are in very close proximity to the washing machine, it could now actually be more efficient to have h and c fill agaib.
If that makes sense?
