Envirosun M9 200L Heat Pump Hot Water System
The Envirosun M9 200L Heat Pump Hot Water System is a compact air-source heat pump designed for smaller to medium households wanting efficient stored hot water without moving to the larger M9 330L model.
Commonly marketed as the M9 200L, the ES200M9 has a listed total water capacity of 190L. It combines R290 refrigerant, inverter heat pump technology, a 1.5 kW electric element, TFT LCD control, multiple operating modes and quiet 42 dB(A) operation at 2 metres.
Installed Today offers the Envirosun M9 200L as a supply-only heat pump hot water system or with supplied-and-installed options across selected Brisbane and Gold Coast service areas, where available.
What Does the Envirosun M9 200L Do?
The Envirosun M9 uses heat from the surrounding air to heat water stored inside its integrated cylinder.
Instead of relying primarily on direct electric resistance heating, the refrigeration system absorbs ambient heat and transfers that energy into the water. This allows the M9 to provide stored hot water while reducing reliance on the electric element during normal heat pump operation.
An integrated 1500 W electric element provides additional heating capability when required by the selected operating mode or system conditions.

Smaller to Medium Households
The compact 190L actual storage capacity can suit households with moderate daily hot water demand where a larger 330L system is not required.
Townhouses & Compact Homes
Its smaller dimensions can make the M9 200L relevant to townhouses, secondary dwellings and homes with less space available for a larger heat pump.
Electric Hot Water Upgrades
The M9 can suit selected electric storage replacements where the installation area provides suitable airflow, drainage, electrical supply and service access.
What Problems Can the Envirosun M9 200L Help Solve?
High Electric Water Heating Use
Heat pump technology uses ambient air energy to reduce reliance on direct electric resistance heating during normal operation.
Need for a More Compact Heat Pump
The M9 200L is significantly smaller than the 330L version and can suit homes where a large-capacity unit is unnecessary.
Noise-Conscious Installations

How Efficient Is the Envirosun M9 200L?
The ES200M9 has a published COP of 4.16 under stated 20°C / 15°C ambient test conditions.
COP compares useful heat delivered with the electrical energy consumed under the specified laboratory test. A COP above 4 indicates that the heat pump transferred substantially more heat energy into the water than the electrical energy consumed during that test.
Actual household electricity use and running costs vary with climate, incoming water temperature, household demand, electricity tariff, timer settings and how often electric-element heating is used.
42 dB(A) Sound Pressure Level at 2 Metres
The Envirosun M9 200L has a listed sound pressure level of approximately 42 dB(A) measured at 2 metres.
The system also includes a Mute operating mode for situations where reduced operating noise is preferred during selected periods.
Installed sound can still vary because nearby walls, fences and structures can reflect noise. The final position should consider bedrooms, neighbouring properties, windows and outdoor living areas.
What Operating Modes Does the Envirosun M9 200L Have?
Eco Mode
Designed for efficient heat pump operation during normal household use.
Fast Recovery
Provides a higher-recovery operating option where hot water demand is stronger.
All Electric
Uses the electric element rather than normal heat pump operation when selected.
Mute Mode
Provides reduced-noise operation for periods when quieter system operation is preferred.
Timer Control
Allows heating periods to be scheduled around household routines or suitable electricity tariff periods.
Solar-Friendly Scheduling
Timer control can be used to help align heat pump operation with periods of available solar PV generation.
Can the Envirosun M9 200L Be Scheduled Around Solar PV?
Yes. The M9 includes timer controls that can be used to schedule hot water heating during selected periods of the day.
This can be useful for homes with rooftop solar where the owner wants the heat pump to run during periods of stronger solar generation.
Timer scheduling helps align operation with solar availability but should not be treated as a direct solar-inverter connection unless the installation has specifically been configured that way.
What Refrigerant Does the Envirosun M9 200L Use?
The ES200M9 uses R290 natural refrigerant, with a listed charge of approximately 0.42 kg.
R290 is flammable, so refrigeration-related work must only be performed by appropriately qualified personnel and the heat pump must be installed in accordance with the manufacturer's requirements.
What Water Temperature Can the Envirosun M9 200L Reach?
The listed default water temperature is 60°C.
The heat pump itself can produce stored water temperatures of up to approximately 65°C, while heater-supported temperature adjustment is listed from 35°C to 75°C.
Delivered tap temperature remains subject to the property's tempering arrangements and applicable plumbing requirements.
Can the Envirosun M9 200L Operate in Cold Weather?
The M9 200L has a published ambient operating range of approximately -7°C to +45°C.
The system includes frost-protection and anti-freeze functions to support operation during colder conditions.
Heat pump performance and recovery can still change as outdoor temperatures vary.

Will the Envirosun M9 200L Fit in the Existing Location?
The ES200M9 is approximately 580 mm x 620 mm x 1746 mm.
The packed unit with pallet is approximately 695 mm x 695 mm x 2060 mm, so the delivery route should be checked as well as the final installation position.
The net weight is approximately 93 kg, while the filled operating weight is approximately 282 kg.
What Water Pressure Requirements Apply?
The supplied technical information lists a maximum tank pressure of 700 kPa.
The property's incoming water pressure and existing valve arrangement should be checked before installation. A pressure limiting valve, expansion control valve or replacement valve set may be required depending on the existing plumbing and installation conditions.
Old, missing or non-compliant valves should not be assumed to be suitable for a new heat pump installation.
Does the Envirosun M9 200L Need Condensate Drainage?
Yes. Heat pump operation produces condensate, so the installation needs a suitable drainage arrangement in addition to normal hot water safety-valve discharge requirements.
The installation position should allow condensate to drain freely without causing water damage, nuisance or access problems.
Can the Envirosun M9 200L Replace an Electric Storage Water Heater?
The M9 can be considered as an energy-efficient alternative to conventional electric storage where household demand and site conditions suit a 190L heat pump.
A heat pump conversion is not necessarily a direct tank swap because airflow, condensate drainage, electrical requirements, service clearances, operating noise and base support also need to be assessed.
Electric Storage Replacement
The compact M9 can suit selected smaller electric storage replacements where household demand is appropriate.
Changing Technology
Moving from resistance electric storage to a heat pump introduces airflow, refrigeration and condensate requirements.
Relocating the System
A different installation position can require additional pipework, drainage, electrical work, base preparation and labour.

Tempering valve information:
Where a hot water system is capable of delivering water above 50°C, a compliant tempering valve must be installed to control the temperature delivered to personal hygiene fixtures such as showers, baths, basins, and bathroom outlets. This helps reduce the risk of scalding and assists with meeting plumbing compliance requirements.
A tempering valve blends hot and cold water to deliver a safer controlled outlet temperature to required fixtures. The hot water unit itself may store water at a higher temperature, but the water delivered to personal hygiene outlets must be controlled where required by plumbing regulations.
If your property already has a suitable, compliant tempering valve installed, your licensed plumber can assess whether it is appropriate for use with the new hot water system. Existing valves may not always be suitable due to age, condition, compliance requirements, valve type, location, or system compatibility.
If a compliant tempering valve is not already installed, or if the existing valve is unsuitable, one must be supplied and installed by a licensed plumber as part of the hot water installation.
Tempering valves are not automatically included with every supply-only hot water unit unless specifically selected, listed as included, or purchased as part of a suitable valve kit. If a tempering valve is required, please purchase the appropriate valve kit with your order or arrange for your licensed installer to supply and install the correct tempering valve on site.
It is the customer’s responsibility to ensure the installation is completed by appropriately licensed trades and that all required valves, fittings, electrical work, plumbing work, and compliance requirements are allowed for as part of the installation.
