What is your solution to the (then) requirement for a zero length pipe
between the hot water cylinder and the machine?


In a sensibly designed house the taps used most often will be near
the source of hot water and the hot water pipes insulated. The
washing machine will be too. As a result hot water will arrive at
the machine almost instantly.


Do you not think that other considerations should be considered far
more important than this in sensible design?


I certainly would. For example, a two story house with basement. The hot
water heater is in the basement (NG). Should we 1) carry laundry up/down
two flights of stairs everyday to reach the washing machine from the main
bath and bedrooms, or 2) install the laundry upstairs in a hall closet area
between bedrooms and bath.

In (1), we have less than ten feet of piping from heater to machine, but
constant 'stockpiling' of laundry waiting to be carried up/down. In (2) we
have ~30' of pipe and much more convenience. And since the machine is only
rarely set to use 'hot' versus 'warm' or 'cold', the savings of 20' of
piping is quite miniscule compared to the labor of hauling laundry up/down
two flights of stairs.

Some may consider putting the machine in the basement 'sensible', but they
*obviously* aren't the ones that do laundry in their home ;-)
