"Electric heaters do not require a minimum flow"
You only get out the pressure which goes in, recently there was not enough pressure for the electric water heaters to work at all, which is where this thread started.

Why cold showers could be good for you
Cold showers are not the primary treatment for any conditions, and conclusive research about cold therapy is still limited. But a quick blast of cold water can be beneficial when used for symptom relief.
Taking cold showers may:
1. Bolster your immunity to common colds
Going from a hot to cold shower — even for a couple of minutes — might protect you from circulating viruses. The shock of cold water can stimulate the blood cells that fight off infection (leukocytes). One study in the Netherlands found that people who switched to cold showers for 30, 60, or 90 seconds for 90 days called out sick from work 29% less than people who didn’t switch to cold showers.
2. Combat symptoms of depression
Limited research is available about the effects of cold water therapy on depression. But the research that exists shows some positive results. In one clinical study, participants who took daily cold showers for several months reported decreased depression symptoms. Additional research suggests that cold water may boost your mood and decrease anxiety.
3. Improve circulation
Cold water strains your body — it goes into “survival mode,” working hard to maintain its core temperature. This stimulates your body to increase blood flow circulation.
“Increasing circulation redistributes blood and delivers freshly oxygenated blood to areas of the body that need to recover,” Dr. Hame says. “It decreases the time it takes your muscles to recover after exercise.” Over time, your circulatory system may become more efficient and move blood through the body more quickly — helpful for anyone with high blood pressure or diabetes.
4. Increase metabolism
Your body expends energy trying to stay warm in a cold shower. The result may be a small amount of calorie burn and increased metabolism. But don’t plan to throw your healthy eating and exercise plan out just yet — research on this benefit is limited.
5. Reduce inflammation and prevent muscle soreness
Cold temps make your blood vessels tighten up (vasoconstrict). When that happens, blood moves to your body’s core and vital organs. The blood naturally becomes oxygen- and nutrient-rich during the process.
As your body heats up again, the blood vessels expand (vasodilate), bringing that oxygenated blood back to your tissues. As it flows back, it helps to flush out inflammation — a cause of delayed-onset muscle soreness, which can occur a couple of days after exercise.
6. Relieve localized pain
Cold therapy alleviates pain by reducing inflammation. But it also interferes with your brain’s perception of the pain. “If you’ve ever been given cold spray before an injection,” Dr. Hame says, “it works by decreasing how quickly the pain sensation travels through your nerves.” It dulls the nerve transmission sent to your brain.
