Why Choose This System

Higher Efficiency, Faster Recovery, Quieter Operation

The Envirosun HP Plus 330L is a cutting-edge air source heat pump that combines inverter efficiency, R290 natural refrigerant, and advanced design. The largest capacity in the HP Plus range, delivering up to 21kW of stored heat energy for larger Australian family homes.

Up to 73% Less Energy

The HP Plus ES330M9 receives 21 STCs — the highest rating in its class — saving approximately 29,000kWh over its lifetime. That’s over $7,000 in energy savings over 10 years, with a break-even time of less than 3 years.

🔄

Inverter Technology

Advanced inverter technology ensures faster recovery times and higher efficiency — delivering hot water on demand without wasting energy. Whether running multiple showers or filling a bath, the 330L meets demand with precision.

🔇

Whisper-Quiet at 42dBA

Operating at just 42dBA at 2 metres — one of the quietest systems available. Mute mode reduces operation noise further for silent overnight heating, so you wake up to a hot shower every morning without any night-time disturbance.

☀️

Solar Ready

The perfect partner for rooftop solar PV. Store up to 21kW of heat energy in the 330L tank ready for use after the sun goes down. Automatic timers maximise solar power utilisation during the day without compromising hot water supply.
