High efficiency and energy saving: up to 93% heating/bathing thermal efficiency, national second-level energy saving.2. Low water pressure start: low pressure combustion, water consumption during peak hours, high-rise users, suitable for more installation environments.3. One-button switching of firepower: adjust the number of burners according to the actual needs of users, warm in winter and not hot in summer.4. Intelligent constant temperature: widened pipe diameter design, improved heating efficiency, continuous hot water,intelligent constant temperature technology, small fluctuations in water temperature difference.5. Leakage protection plug: in case of accidental leakage, quickly cut off the power supply.6. High-strength bracket: anti-corrosion and durable, strong supporting ability.7. Antifreeze protection: The sensor monitors the water temperature. If it is lower than 8°C, the water pump will run normally;if it is lower than 5°C, it will burn, and then stop when it burns to 30°C; if it is lower than 3°C, the machine will automatically prompt the user to perform antifreeze treatment.Zhongshan Vangood Appliances Mfg Co.,Ltd. is an enterprise specialized in electric and gas appliances.
