Description
Envirosun HP Plus 200L
Heat Pump Water Heater
The next generation in energy efficient hot water. The Envirosun HP Plus ES200M9 uses inverter technology and R290 natural refrigerant for faster recovery, whisper-quiet operation, and up to 73% energy savings — backed by a 7-year tank warranty.

Higher Efficiency, Faster Recovery, Quieter Operation
The Envirosun HP Plus is a cutting-edge air source heat pump that combines inverter efficiency, R290 natural refrigerant, and advanced design. Two years in development and decades of Envirosun experience — delivering performance that sets a new standard for Australian homes.
Up to 73% Less Energy
The HP Plus ES200M9 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 a bath or multiple appliances, the HP Plus 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. Automatic timers maximise solar power utilisation during the day. The highly insulated tank stores heat energy ready for use after the sun goes down — hot water all evening without drawing from the grid.
STC Rebates Available
Qualifies for federal Small-scale Technology Certificates with 21 STCs — the highest rating in its class. State rebates including NSW ESCs and Victorian VEECs may also apply. We handle all the paperwork.
Local Illawarra Install
Installed by our licensed local team. Same-day and next-day availability across Wollongong, Shellharbour, and the Illawarra region. Must be installed by a licensed plumber.
