Abstract
In a hot water distribution system, a priming device installed just ahead of a tap stores a small amount of water and continuously maintains it to the temperature of the hot water source. When the tap is opened, the water from the priming device is first drawn while the cooled down water which was stationary in the pipe coming from the heating tank refills the priming device. When the pipe is cleared of cold water the priming device is bypassed, and its stored cold water is slowly admixed in the flow of hot water to the tap.
