Tap cold water temperature

Automatic Washer - The world's coolest Washing Machines, Dryers and Dishwashers

You didn't need to do that, water temp that warm is good for detergents.
Now only if we could harness that temp all year round, ATC will never add hot water to the wash and savings will be seen in a year or two.[this post was last edited: 6/14/2010-09:26]
 
No, Jon, it's that warm out of any cold water faucet. It has been a very much warmer than usual Spring and the water has warmed up quickly.

"Cold" water that gets very warm during the hot months of the year adversely affected drying performance in condenser combos in places like Florida where the cold water can reach comfortable bath water temperatures as the sandy soil transmits heat so efficiently to the water mains.
 
Some models with ATC offer a choice of "Cold ATC" or "Cold non-ATC" (latter=cold water line temp) and the latter setting would be perfect for your situation.

My cold tap water is warm enough to wash on Cold only in July-Aug-Sept. Rest of the year I have to wash on Warm, and I don't have ATC.
 
All three machines are hot & cold fill, operate on 220 volts and heat the wash water, but only rinse with cold water. I use the tempering valve to keep the cold rinses at about 80F during the months when the cold water is below 80F.
 
My tap cold water temp is getting warm too. Our water department says the water temp at the sources varies between 32F and 88F. I don't think it is 88F yet but when August arrives my cold water turns into warm water. I don't like rinsing clothes or my hair in it. I prefer very cold rinses.
 
I've never had water that warm in Portland....even in the middle of summer, it adds warm water to temp controlled cold washes (Cool setting on the new Admiralpool).
 
It varies.

When I lived in another town about 30 miles away, the cold tap water always seemed to be on the cool side.

But in this house, the water does warm up considerably in the summer.

I believe it's both the source and the depth at which the water pipes are laid. I figure they are at a more shallow depth is this town, and therefore heat up during the summer more than more deeply buried pipes might warm up.

The climate difference between the two locations isn't enough in and of itself to account for the temperature difference.
 
with well water, and maybe cause mine is so deep, no matter what is always chilly....summer or winter....but as an experiment, I took 3 100foot garden hoses, left them somewhat coiled on the ground, ran the hoses from the outside faucet thru the hose, into the window, hooked up to the hot water line of the washer....free solar hot water....

common sense tells you can only do laundry during morning to later afternoon hours for the hottest water, and once the machine finishes, hot water is replenished for the next loads....this worked well for me with 3 FL machines...
 
Incommng water temp this am

is 93 not uncommon to reach 100+ during July and August In fact some times have problems with it being too hot for blood loads and are forced to use old hot break alkali formula on OR and ER linen.
 
Our water has warmed up considerably as it does every year. It goes from around 38 in January to above 80 in July and August. Its about 75 now.

Drinking water out of the tap in the winter is just delicious. On the other hand from May-November I use cold rinses where as the other six months I use warm rinses. Every last washer that we've had that doesn't have a warm rinse setting has been sent off and away!
 
Hot Break Alkali Formula

Lee, do you use STPP for that or a less expensive caustic additive? With those water temperatures, I guess no one is told to take a cold shower to cool off in the Summer down there.

Friends who used to live in Dallas, Texas said that if they wanted to have a pool party during the summer, they had to have blocks of ice delivered to cool the water from bathtub temperatures. And after all of that sumer heat, they had to bring tropical plants inside during the winter. We are shaping up for a very warm Spring. So far in June over half the days have been 90 or above. That is unusual, even for this former malarial swamp. Strings of 90+ days used to come in July or August.

Has anyone seen the rooftop cisterns in the deep South that used to be used for solar water heating?

I use STPP but I also use a high Alkali Detergent with it to break up blood and keep it from setting.. Ecolab Soil Out Xtra is a VERY high alkali product and if not careful will "burn" your hands in a instant.It is very reasonably priced for us too. On contract a 45 box is only 45.oo list is almost 150.oo On a 150 lb load only have to use 16 to 20 oz. And 2 oz of STPP
 
Cold, cold water!

I couldn't believe what I read! I live in freeze or bake country, here, the water lines have to be at least 4' below ground so they don't freeze in the winter & the soil is dense so it stays cold. I have city water & in the winter, the cold water flowing into the washer is like ice water. I has to be really hot for quite a spell for the cold water to be less than cool. I have window air conditioners & usually don't put them in until the end of May & take than out last of September.
