Using microcomputer hot water boiler controller, LCD screen display with built-in backlight, the operating status of the boiler is clearly visible. All operations are simply done with the keys of the button, and the boiler controller’s super display function and control function are very complete.

The ceramic electric heating tube type hot water boiler adopts the electric heating mode of “water and electricity separation”, which completely separates the electric heating tube and furnace water, and the boiler is safe to use and convenient for maintenance and replacement of the heating tube; Stainless steel electric heating tube type hot water boiler implements “immersion” electric heating mode, the furnace water heating up quickly, high efficiency, heating tube and furnace body flange connection, easy to clean, disassemble and replace.

The user can set the water temperature arbitrarily between 30 °C and 90 °C, and the boiler will supply heat to the heating circulation system automatically according to the user’s requirements or provide users with bathing and domestic hot water.

The high-power boiler adopts the step-by-step time-sharing input method to control the heating group, and the heating group can be randomly input or stop working according to the load change, which significantly reduces the impact on the power grid. At the same time, the number of heating sections can be manually started and stopped, so that users can adjust the electric power of the boiler by themselves.

  • 1The control system controls the start and stop of the circulating pump according to the furnace water temperature. Using a hot water boiler for heating, the hot water circulation pump starts when the furnace water reaches the set upper limit water temperature, and the hot water circulation pump stops when the lower set lower water temperature is lower; Using a hot water boiler for bathing, the hot water circulation pump stops when the furnace water reaches the set upper limit water temperature, and the hot water circulation pump starts when the set lower limit water temperature is lower.
  • 2The inside of the bathing and domestic hot water boiler is treated with anti-corrosion, the furnace body is not easy to rust and corrode, the boiler has a long service life, and the hot water quality is clean and hygienic. High-grade centrifugal glass fiber silk cotton multi-layer heat preservation is adopted, which has less heat loss and energy saving and consumption reduction; Famous white color plate exquisite packaging, beautiful appearance, generous rust resistance.
  • 3The boiler has the function of leakage protection (the control system automatically cuts off the boiler power supply after detecting the leakage of the power supply appliance), the function of anti-dry burning extremely low water level protection (when the water level is lower than the set minimum limit water level, it will immediately stop and alarm), the furnace body overheating protection function (when the temperature of the boiler shell exceeds 105 °C, immediately stop and alarm, and automatically start the boiler after the temperature is normal), temperature sensor abnormal protection function (the control system continuously detects the sensor situation, immediately stops and alarms), Power supply voltage abnormal protection function (when the power supply is abnormal, the power is automatically cut off.) After normal, it will automatically resume work), heating component phase failure protection function (shutdown protection after monitoring the phase loss of heating component).
  • 4The top of the boiler is equipped with an exhaust port connected with the atmosphere, the inner tank is not under pressure, the boiler works under normal pressure, there is no risk of explosion, and the potential safety hazards are completely eliminated.
  • 5Symmetrical design of outlet and return port (double in and double out), suitable for quick connection and installation; Boiler mechatronics, compact and reasonable, very convenient transportation.
  • 6Electric hot water boilers are widely used in residential areas, villas, swimming pools, bathing centers and other places, compared with other traditional boilers, it has significant advantages of environmental protection and hygiene, convenience and worry-free, noise-free and pollution-free.
