Product Introduction: Utilizing side-jet combustion technology, it achieves maximum complete combustion and heat conversion, ensuring the boiler's thermal efficiency and reducing users' operational costs. Equipped with an automatic control system featuring a liquid crystal touch screen display and an in-built low-water protection device; temperature can be easily set and adjusted. Once the set temperature is reached, the water automatically operates (can also be used for circulation heating or temperature increase). It is a pressureless hot water boiler, requiring no additional operation. Pre-setting boiler parameters based on user needs facilitates various requirements. Materials include carbon steel plates, aluminum alloy plates, and stainless steel plates. The side-jet combustion technology maximizes complete combustion and heat conversion, ensuring the boiler's thermal efficiency and reducing users' costs.
