ABSTRACT:
A water purifying and heating apparatus having a pump supplying water to a purifying filter connected by conduit to a boiler and capable of being used with domestic electric power supply. The load current required for start-up of the pump is reduced, and the automatic flushing effect of the hollow fiber membrane filters is obtained as is hot water as needed, without reducing the treatment efficiency of the purifying filter even though the temperature of water being treated is low.
