Yes...
I understand that...but maybe that would be a good thing in Manhattan as there's the common steam piping from Con Ed and NYC Steam system servicing all the area, but as time is money as you say few would do that...forget in other places than NYC.
And really...nobody likes to wait...hence a reason more why opt for hot fill.
I wonder if customers wouldn't be the first ones complaining for long times?
Over here steam is really not used, not even for condo home heating, what cicrculates in radiators is water... except for very large laundries..then a steam furnace makes no sense..and I really think doesn't in a laundromat,even more a typical european small one.
Most laundromats in this country are in residential buildings too, as gas reaches everywhere and is cheap this is the main source for heating, what you have here is gas boilers in the backroom, there might be machines capable of self heating with gas also, I sure know of some used in laundries but not born for coin laundry and you need anyway to vent a row of say 10 machines, you can't do that easily in a commercial space, same reason why here many laundromats do have condenser dryers, condenser dryers takes longer, and while they require less gas to heat they require water to cool condensers, all laundromats with condenser dryers ask more money to run a cycle than ones with vented dryers...
I think that it all changes also upon the country, but even in countries as France where electricty cost less what I could see in French "laverie" were hot fill machines...perhaps an electric boiler instead of gas?
I think that I really never seen a Miele like that in a Laundromat here or places i traveled, that actually looks more like a typical professional Miele washer adapted to laundromat use, not born to do the coin laundry specifically...they sure do heat..they also use 380 volt commercial voltage IIRC.
After all that's Germany and they will use their machines... another thing I newer saw is coin-box-less 5kg home-style machines in use in laundromats, while I'm seeing you could see some german "waschsalon" with them...
That's typical german I guess...not what comes to mind when I think of coin laundry.
Anyway...lucky us we have a washer, 2 or 3...LOL
But if I ever needed to use a front loader in a laundromat, sure i'd want to get spoiled too and use one like that reaches 90....
Unfortunately...this is not the case for most laundromats i could and can see around.. common are for sure the greed owners and dingy whites.
Well....actually, to be really spoiled I'd want at least a vintage one like Diomede's (vivalavatrice)one....too bad it's almost 2hrs from me.
