Dry running protection, also known as dry-run protection or dry-running protection, is a type of protection mechanism to prevent a rotor, pump or stirrer shaft from operating without any medium added, as the bearing and shaft seal might be damaged if the motor is run while dry. [1]
Booster pumps for household water pressure are usually simple electrically driven centrifugal pumps with a non-return valve. They may be constant speed pumps which switch on when pressure drops below the low pressure set-point and switch off when pressure reaches the high set-point, or variable speed pumps which are controlled to maintain a ...
Tankless water heaters — also called instantaneous, continuous flow, inline, flash, on-demand, or instant-on water heaters — are water heaters that instantly heat water as it flows through the device, and do not retain any water internally except for what is in the heat exchanger coil unless the unit is equipped with an internal buffer tank.

The wildfires in Los Angeles continued to burn mostly out of control, with at least five blazes being fueled by dry conditions and ferocious winds in California.
When overheating, the temperature of the part rises above the operating temperature. Overheating can take place: if heat is produced in more than expected amount (such as in cases of short-circuits, or applying more voltage than rated), or; if heat dissipation is poor, so that normally produced waste heat does not drain away properly.
There are a few possible side effects linked to taking NSAIDs, including: gastrointestinal problems (such as irritation, ulcers, or bleeding), increased risk of heart attack and stroke, reduced ...
It’s a problem that worsens with age as sleep becomes more precious. In fact, women older than 70 who slept fewer than five hours a night were 30% less likely to be sexually active than women ...
