Composition of heating system: 1, boiler 2, distribution main: 3, radiator 4, temperature control system: features of oil-fired and gas-fired atmospheric hot water boiler 1, equipped with imported brand burners, with high degree of automation, automatic purging according to the instructions of the controller, electronic automatic ignition, automatic combustion, automatic adjustment of air/oil (gas) ratio, safe and stable performance and good combustion effect. And there is a flameout protection device to ensure safe operation. 2. Computer-based hot water boiler controller. All functions are magically stored on smart chips. The boiler can be started with one key, and it can run at constant temperature automatically. Users can set the start and stop time of the boiler. After the setting is completed, there is no need for someone to be on duty, which saves trouble and effort. 3. A flame retardant spoiler is inserted in the fire tube to slow down the smoke exhaust speed and strengthen the heat exchange. The temperature of flue gas discharged from the smoke chamber is low, which reduces heat loss and saves fuel. 4. The water temperature is displayed in large font, which is convenient to master the running state of boiler and system. The water temperature can be set arbitrarily between 10℃ and 90℃, and the boiler can automatically heat the system or provide users with hot water for living and bathing. 5. The control system controls the start and stop of the circulating pump according to the boiler water temperature. The hot water circulating pump starts when the boiler water reaches the set upper limit water temperature and stops when it is lower than the set lower limit water temperature. 6. The horizontal oil-fired gas-fired hot water boiler is a three-return, full-wet-back structure, with a large furnace and a large flue design, which increases the radiant heat absorption of the furnace and effectively saves energy and reduces consumption. The use of threaded smoke pipes and corrugated furnace liners greatly enhances the heat transfer effect and greatly saves fuel consumption. 7. At the same time, the whole machine is equipped with overheating protection (when the water temperature in the boiler is too high, the burner will automatically stop working and give a buzzer alarm), secondary overheating protection (when the boiler shell temperature exceeds 105℃, the secondary circuit will be automatically cut off), dry burning water shortage protection (when the boiler water is lower than the extremely low water level, the boiler stops working and gives a buzzer alarm), and boiler leakage protection (after the control system detects leakage and short circuit) 8. The boiler is designed according to the normal pressure structure. The boiler is in a pressure-free state, and there is no potential safety hazard. 9. High-grade centrifugal glass wool multilayer insulation is adopted, and the outer packaging is made of famous white color steel plate, which has less heat loss, beautiful appearance and corrosion resistance. 10, widely used in families, villas, hospitals, schools, hotels, fitness centers, bath centers and other enterprises and institutions.
