Feature two: the surrounding of water heater arranges poly-peace fat insulating foam layer, slows down radiating rate, reaches energy-conservation object.
Feature three: shower nozzle is power-off from breaker device takes off, makes water heater safer.
Feature four: the safety valve of check-valves, relief valve, pressure-reducing valve three valves unifications is installed on the water inlet pipe of water heater, is improved water heater service life, make the malfunctioning rear water heater liner of water heater temperature limiter can explosion.
Feature five: the water pipe of the pressure relief opening of three-in-one safety valve is directly connected with the pressure relief opening of mixing valve of water heater, does not affect the appearance.
Feature six: the pressure-reducing valve of three-in-one safety valve guarantees that water feeding pressure is no more than 0.3Mpa, when relief valve exceedes 0.6Mpa, three-in-one safety valve can be opened pressure release automatically, ensures the use safety of water heater liner.
Feature seven: three-in-one safety valve can manually opened relief valve be discharged the incrustation scale in inner bag, make safety valve in let out function and can not lose efficacy because incrustation scale stops up, ensure that the operating pressure of inner bag, within normal range (NR), makes water heater safer, durable.
