What's Included
- Andrews MAXXflo EVO 120/302 twin‑burner water heater
- Integrated 300 L stainless steel storage tank
- Electronic control system with Modbus connectivity
The Andrews MAXXflo EVO 120/302 is designed for buildings where hot water demand is both high and constant. With a twin‑burner configuration delivering up to 122 kW of output and a 300‑litre stainless steel tank, it provides a fast and reliable supply even at peak times. Its condensing design achieves up to 98% gross efficiency, making it a smart choice for reducing running costs in large commercial settings such as hotels, hospitals, and care facilities.
Durable, Service-Friendly Design
At its core is a 300L stainless steel tank and heat exchanger system, chosen for its strength and corrosion resistance. Each burner and heat exchanger can be serviced independently, meaning maintenance can be carried out without shutting the whole unit down. This built‑in redundancy keeps downtime to a minimum - a key advantage in busy environments where hot water is critical.
Smart Control and Easy Integration
The MAXXflo EVO comes with advanced electronic controls, a clear multi‑line display, and full BMS integration via Modbus. This allows for remote monitoring and easy adjustment of settings, ensuring the system runs efficiently and safely at all times. It also features low NOₓ burners, high‑efficiency pumps, and anti‑legionella protection, combining environmental responsibility with reliable performance.
