Maybe you just need a new system
If the sea gets more heat than it loses, then, obviously, it will get hotter. This will continue until a new equilibrium is reached: being hotter, it will also lose heat faster.
Water molecules loose its state. It gets converted into vapors.
There is a screen and/or a water saver in the shower head. The screen may be plugged with sediment from in the water.
In a vacuum, water does not change temperature since temperature is a measure of average kinetic energy of molecules, which in turn depends on molecular collisions that require a medium. Without air or molecules to transfer heat, water cannot gain or lose temperature in a vacuum.
When flowers lose their turgor pressure, or dry out they become wilted. If you remember to water them, flowers have abundant turgor pressure, and they will stay stiff, but if they become dry, or you forget to water them, they will lose their turgor pressure and begin to wilt.
When water is lost from a plant, the cells in the plant lose turgor pressure, which is the pressure that water in the cells exerts against the cell walls. This turgor pressure helps maintain the plant's rigidity and structure. Without enough water, the cells lose this pressure, causing the plant to wilt and lose its firmness.
The cold side inlet may be plugged with sand or rust.
water loses it's most heat because the stored in the water gets out in steam.
1. Because like everything it has a limited storage and gets rid of old water to get new water
check for leaks
A leak on the return or supply lines and the automatic feeder is not working
Hotter climates may increase swelling in the body. If it is hot, your body will sweat and lose fluid. To help combat dehydration and water retention, drink plenty of water.
