When water doesn’t reach boiling point, it can not make perfect drinkable; when water is over boiled, nitrite will be cumulated in the water, which become harmful.
Water dispenser and water boiler with critical boiling point controlling system contain dual built-in tanks, namely heating tank and expansion tank. Water can be heated to up to 99°C, whereas water tank pressure can be kept at zero for safety. Our water dispenser and water boiler are also able to vary their power intelligently and auto-adjust the boiling point according to the altitude, these features allow water reaching critical boiling point while not over boiling. Water would be fresh and energy is also saved.
