About the Envirosun M9 330L Heat Pump

The Envirosun M9 330L uses heat pump technology to draw heat from the surrounding air and transfer that heat into stored water. This helps reduce reliance on direct electric element heating and can lower hot water running costs compared with a traditional electric hot water system depending on usage, tariff setup, climate and installation conditions.

This model is the larger M9 option, with the official model ES330M9 listing a 330L total water capacity. It is designed for larger households, higher hot water users and homes wanting more stored hot water capacity than the 200L-class M9 model.

The M9 range uses R290 refrigerant, inverter technology, a microchannel condenser, triple full-length anodes and a user-friendly TFT LCD control screen. It also includes multiple operating modes, including All Electric, Fast Recovery, Eco and Mute mode.

R290 Heat Pump Efficiency

The Envirosun M9 330L uses R290 natural refrigerant and inverter heat pump technology to help heat water efficiently.

Heat pump technology works by absorbing heat from the surrounding air and transferring that energy into the stored water. This allows the system to produce more heat output than the electrical energy it consumes under suitable conditions.

The 330L model is listed with a COP of 4.04 under stated test conditions, helping position it as a strong option for households wanting a larger heat pump hot water system with efficient operation.

Actual running cost savings can vary depending on the water heater being replaced, household usage, tariff setup, climate, installation location and timer settings.

Quiet 42 dB(A) Operation

The Envirosun M9 330L is designed for quiet operation, with a listed sound pressure level of 42 dB(A) measured at 2m.

This makes it a strong option for customers who want a larger heat pump hot water system but are also conscious of noise around homes, townhouses, side paths, boundary areas or outdoor living spaces.

Installation location still matters. Airflow, clearance, wall position, neighbouring rooms and surrounding surfaces can affect how sound is experienced on-site.

Smart Operating Modes

The Envirosun M9 330L includes multiple operating modes to help match hot water production to household routines.

Operating modes include:

• All Electric mode for electric element operation

• Fast Recovery mode for higher hot water recovery demand

• Eco mode for efficient heat pump operation

• Mute mode for quieter overnight heating

These modes give households more control over efficiency, recovery and noise depending on how and when hot water is used.

Solar PV Friendly Timer Control

The Envirosun M9 330L includes advanced timer control that can help households schedule hot water heating during selected times of day.

This can be useful for homes with solar PV, where the system may be timed to run during daylight hours when solar generation is available. A second timer can also help support early morning boosting where required.

This makes the M9 range a practical option for customers wanting to use more of their own solar power for hot water where the home setup, tariff and installation conditions are suitable.

Triple Anode Tank Protection

The Envirosun M9 330L includes triple full-length anodes to help support tank durability and corrosion protection.

Anode protection is an important part of storage hot water system design, especially where water quality can vary. Correct installation, maintenance, water quality checks and warranty conditions still apply.

Common Uses

The Envirosun M9 330L can be suitable for:

• electric hot water system replacement

• heat pump hot water upgrades

• larger family homes

• busy households

• rental properties

• homes with higher daily hot water use

• homes with solar PV where daytime operation can be scheduled

• customers wanting quieter heat pump operation

• customers wanting R290 refrigerant technology

• customers wanting more capacity than a 200L-class heat pump

• customers wanting lower energy use than standard electric storage
