APOLLO DHW120 MAX - Stainless Combined Indirect Water Heater Tank
The APOLLO DHW120 MAX Stainless Indirect Water Heater Tank is a robust and high-capacity solution designed to produce abundant domestic hot water by using a separate hydronic heat source. Constructed from 316 stainless steel, this tank offers excellent corrosion resistance and long-term durability, making it suitable for demanding residential or commercial applications where reliable hot water delivery is essential. Its indirect design allows the unit to efficiently heat and store water using energy from an external boiler or heat pump, rather than relying on internal burners.
This water heater tank is engineered for seamless integration with hydronic systems and works effectively with all standard glycol-based fluids. The indirect heating approach maximizes efficiency by leveraging the system’s existing heat source, supporting not only consistent hot water output but also improved overall energy utilization. The stainless steel build also helps maintain water quality while resisting wear over time.
The APOLLO DHW120 MAX model is ideal for larger households, multi-family units, or commercial facilities where significant hot water demand is common. Its design ensures consistent performance even under repeated use, making it a practical choice for environments that require dependable and sustained hot water supply.
With its durable materials, efficient hydronic operation, and compatibility with various heating sources and system controls, the APOLLO DHW120 MAX Stainless Indirect Water Heater Tank delivers a dependable and high-performance hot water solution for a wide range of applications.
