1. Computerized hot water boiler controller, one-key start of the boiler, automatic timing and constant temperature operation, the user can set the start and stop time, after the setting is completed, there is no need to be on duty, saving trouble and effort.

　　2. Equipped with burners, with a high degree of automation, automatic purging according to the instructions of the controller, electronic automatic ignition, automatic combustion, automatic ratio adjustment of air and oil (gas), stable performance, good combustion, and flameout protection devices, which can operate normally.

　　3. A flame-retardant spoiler is inserted in the fire tube to slow down the speed of smoke exhaust and enhance heat exchange. The temperature of the flue gas discharged from the smoke chamber is low, which reduces heat loss and saves fuel.

　　4. The large font displays the water temperature, which is convenient for grasping the operating status of the boiler and the system. The water temperature can be set at will from 10℃ to 90℃. The boiler automatically heats the system or provides users with hot water for life and bathing.

　　5. The control system controls the start and stop of the circulating pump according to the boiler water temperature. When using a hot water boiler for heating, the hot water circulating pump starts when the boiler water reaches the set upper limit water temperature, and the hot water circulating pump stops when the lower limit water temperature is lower than the set lower limit water temperature; when using a hot water boiler to take a bath, the hot water circulates when the boiler water reaches the set upper limit water temperature The pump stops, and the hot water circulation pump starts when the water temperature is lower than the set lower limit.

　　6. The horizontal fuel and gas hot water boiler has a three-pass full wet back structure, adopts a large furnace and large smoke pipe design, increases the price of the furnace and absorbs heat, which saves energy and reduces consumption. The use of threaded smoke pipes and corrugated furnaces greatly enhances heat transfer and greatly saves fuel consumption.

　　7. The whole machine is also equipped with overheating protection, secondary overheating protection, protection against dry burning and water shortage, and boiler leakage protection.

　　8. The boiler is designed according to the normal pressure structure, and the boiler is in a pressureless state and there is no danger.

　　9. The use of centrifugal glass wool multi-layer insulation and the famous white color steel plate as the outer packaging, with less heat loss, beautiful appearance and rust resistance.

　　10. Fuel and gas hot water boilers, heating boilers, bathing boilers, and bathing boilers used in hotels are suitable for families, hotels, hotels, etc.
