What's Included

• Andrews MAXXflo EVO 90/302 twin-burner condensing water heater
• Integrated 300 L stainless steel storage tank

The Andrews MAXXflo EVO 90/302 is built for sites where hot water demand is constant and critical. This twin-burner condensing water heater delivers up to 98% gross efficiency, with a 300 L storage tank and an impressive 1,920 litres per hour recovery rate at a 50 °C rise. Designed for large commercial properties, it meets and exceeds the London Plan’s low NOₓ requirements, making it a future-proof choice for hotels, hospitals, leisure facilities, and similar high-demand environments.

Engineered for Reliability and Serviceability

The twin-burner layout provides built-in redundancy, meaning each burner and heat exchanger can be isolated for maintenance without taking the whole system offline. Independent service valves and pressure sensors on each exchanger make planned maintenance simpler and reduce operational downtime. With 316L stainless steel heat exchangers, a robust condensing flue system, and ErP-rated A modulating pumps, the MAXXflo EVO 90/302 offers outstanding reliability and precise water temperature control.

Smart Control and Full Connectivity

The system is fitted with a multi-line graphical display providing access to live data, full burner control, and detailed history logs for diagnostics. BMS connectivity via Modbus allows for 24/7 remote monitoring and fine-tuned system management, helping facility teams to stay ahead of maintenance and performance needs. It also includes a full anti-legionella function, managing return circuit temperatures and pump operation for improved safety.
