Keep water in fridge
Will let cold tap run a bit, but during heating season don't wait for water to reach "cold" as coming from outside building.
Timed it once and the longest was > four minutes. Actually got up one morning and as per started the coffee, which naturally one wants cold and fresh water. Turned on the cold tap, went to powder room, washed face, brushed teeth, came back looked at timer and felt the water, it was still lukewarm. *LOL*
Water is so warm that when filling the kettle or water pitcher for fridge the containers actually feel warm, not cold at all.
All this comes from building using recirculating pumps for the hot water. This is great for "instant" hot water from the taps, but means pipes or anything next to hot water pipes warms up by close proximity.
During warmer months of year when boilers are set to "summer", and hot tap water is only around 130F, the cold isn't that bad. Indeed the waiting time for "cold" street tap water can be rather short. OTOH now tap hot water is >150F and sometimes nearly reaching 160F.
The AEG Lavamat doesn't like this "warm" tap cold water at all. Certain cycles only have cold as "30C". So incoming water that is easily near 90F if not above is just too warm. Machine responds to this not needing heater by shortening cycles to deduct the time would have been spent heating water.

Tap water systems vary throughout the United States. What works for Boston may be different than Seattle.
Here in NYC our tap water comes from upstate and the system works entirely via gravity. Thanks to the distance travelled and pitch of tunnels water pressure out of the taps is quite forceful. Indeed building up to six or seven stories do not need pumps or roof water tanks because of this situation.
Many buildings both large and small install circulation pumps for the hot water system. This helps cut down on people running the hot water taps to bleed out cold water, and thus saves. As stated water comes out of our hot water tap *hot*. About a few moments later is reaches "very" hot, then a few moments more you've got near scalding hot coming straight from the boilers.
Our water is so good that lone among four other urban areas it isn't filtered.
