The invention discloses a multifunctional gas
water heater. The gas
water heater comprises a
water heater body, a
heat exchanger mounted on the water heater body as well as a water inlet
pipe and a water outlet
pipe which are connected with the
heat exchanger. The gas water heater is characterized in that a three-way valve is connected onto the water inlet
pipe and divides the water inlet pipe into two branches, a water pump is arranged on one
branch of the water inlet pipe, a water purifying and
softening device is arranged on the other
branch of the water inlet pipe, and
ion exchange resin and
activated carbon are arranged in the water purifying and
softening device. Compared with the prior art, the gas water heater has the advantages that the water purifying and
softening device is arranged, water scale production is effectively inhibited, and pipe blockage, especially blockage of a
shower head, is avoided; meanwhile, the
ion exchange resin and the
activated carbon are arranged in the water purifying and softening device,
hard water becomes
soft water after passing through the
ion exchange resin, the
soft water contains little
calcium magnesium salt and is smooth, and the
bathing effect is better; the
activated carbon purifies the water effectively, removes impurities and
dirt, inhibits bacterium breeding and creates a safe, healthy and comfortable
bathing environment.
