Two in one tank

As a professional manufacturer of two-in-one water tanks, Foshan Legend produces multi-functional dual-purpose water tanks, high-efficiency integrated thermal storage cylinders tailor-made for contemporary heating systems.


Adopting an innovative dual-inner-tank construction, one chamber is fitted with a heat exchange coil for indirect heating, while the coil-free compartment serves as a water buffer tank. This versatile heating cylinder stands out for its outstanding cost efficiency. Compared with separate standalone tanks, it occupies far less installation space, delivers rapid heating output and remarkable energy-saving performance, perfectly suited for hybrid heating projects in both residential and commercial settings.
