Learn to save money on electricity if you are using a electric water heater or save on gas if you are using a gas water heater. Continue reading to find out why washing clothes in hot water is a waste of money.
Why Not Wash in Hot Water
Washing your clothes in hot water is really a waste of electric or gas depending on what your water heater uses. The reason washing your laundry in hot water is a waste because most people have their water heater set at 120°F – 140°F. When your washer is set to hot water it only allows hot water to enter the washer, no cold water is added. Therefore your clothes are being washed in 120°F – 140°F hot water when dirt, grime, body odors, sweat, etc. are all best dislodged at 100°F! So that extra gas or electric used to make the water 20°F – 40°F hotter is wasted for no reason at all!
How Can I Make My Washer Use 100°F Water For Warm Water
You rarely need to use warm water to wash your clothes in, but for those loads of laundry that do require warm water you will want to make sure your clothes washer is only using 100°F warm water. Most clothes washers will open both cold water and hot water valves 100% to get it’s warm water. So it will mix 50% cold and 50% hot water to make it’s warm water. Most of you will have around 50°F cold water and 140°F hot water mixing. Your cold water will also depend on the temperature outside and inside your home. The best way to adjust the temperature of your warm water is by adjusting the valves manually yourself. While doing a load of laundry use a thermometer after the water is completely filled and starts swishing around so you know it is mixed well. Take your water temperature during that load and see what it is. If your water temperature is above 100°F, reach behind your washer and turn down the hot water valve. If the water is below 100°F turn down the cold water valve. After you have done this, check the temperature again during your next load of laundry. Keep repeating this process until your washer’s warm water achieves 100°F. Also note, you may have to make this adjustment in the summer and in the winter as your cold water’s temperature will change slightly.
