A hydronic manifold serves as the central hub of a water-based heating or cooling system, distributing flow evenly to multiple circuits for precise temperature control.
It is a critical component in underfloor heating, radiator networks, and domestic hot water systems, ensuring stable operation and energy efficiency.
Jiangsu Easywell offers a comprehensive range of manifolds designed to serve as the backbone of hydronic heating, HVAC, and plumbing systems.
Each manifold is engineered for precise flow control, reliable performance, and seamless integration with complementary system components such as expansion tank brackets and vessel supports.
Our manifold lineup includes high-quality carbon steel manifolds, versatile steel manifolds, and advanced smart manifolds.
Each product is carefully designed and manufactured to ensure stability under fluctuating pressure, long service life, and easy integration into both residential and industrial systems.
Crafted from premium-grade carbon steel, these manifolds are built for heavy-duty performance.
They undergo precision machining and anti-corrosion treatment, ensuring exceptional pressure resistance, mechanical strength, and durability in demanding environments such as industrial heating loops and central boiler rooms.
Providing a cost-effective solution for standard operating conditions, Easywell’s steel manifolds combine reliability and easy installation.
They deliver consistent performance across a variety of hydronic and water distribution applications while maintaining structural integrity under daily use.
One of Easywell’s key advantages lies in system integration.
Our manifolds are fully compatible with expansion tank brackets, vessel consoles, and mounting supports, forming a cohesive distribution network that simplifies installation, enhances system safety, and maintains efficiency over time.
