Abstract:
Electric water heaters are ideal for water heating in
buildings with no central heating or for buildings provided with
central heating but where water is not heated during the summer
months.
In presented electric water heaters an overflow system.
is used in which the water container is constantly exposed to
the outside atmosphere by means of a drain (overflow) pipe. A
drain valve is built in on the cold water inlet pipe in the water
container. Any type of electric water heater can be connected to
this system. The system permits the connection of one overflow
point only.
