With 300L tank volume, R290 refrigerant, built-in Wi-Fi control, solar PV compatibility, 2.4kW electric element, 45 dB(A) quiet operation, and sizing for up to 6 people, it is a strong upgrade option for replacing a larger electric hot water system.
About the Rinnai Enviroflo AR Series 300L Heat Pump
The Rinnai Enviroflo AR Series 300L Heat Pump uses heat from the surrounding air to heat stored water, helping reduce water heating energy use compared with a standard electric storage water heater.
Instead of relying only on an electric element, the heat pump absorbs ambient heat and transfers that energy into the stored water using a refrigeration process. This allows the system to provide efficient hot water while still storing a generous amount of hot water for everyday household use.
The 300L AR Series model is designed for households needing more capacity than compact heat pump options. It can suit family homes, larger townhouses, rental properties and higher-use households where a 180L, 215L or 265L heat pump may not provide enough storage capacity.
Buy Rinnai Enviroflo AR Series 300L Supply Only
Order the Rinnai Enviroflo AR Series 300L Heat Pump Hot Water System online as a supply-only hot water system where available. This option is ideal if you already have a licensed plumber, electrician or installer arranged and only need the unit supplied.
The supply-only product price is for the hot water system itself. Installation, old system removal, disposal, valve kits, electrical work, plumbing alterations, drainage changes, compliance upgrades and additional site requirements are not included unless selected separately as add-ons.

300L Heat Pump Storage for Family Homes
The 300L tank volume makes the Rinnai Enviroflo AR Series 300L a strong family heat pump option.
It gives more stored hot water than compact 180L, 215L and 265L heat pump models, making it better suited to homes with higher daily hot water demand. It can suit households with up to 6 people, depending on usage, climate, tariff settings and installation conditions.
For smaller households, a compact heat pump may be enough. For larger or higher-demand households, the 340L AR Series model may be worth considering.
Efficient Heat Pump Hot Water
The Rinnai Enviroflo AR Series 300L is designed to reduce water heating energy use compared with a standard electric storage water heater.
Heat pump technology works by absorbing heat from the surrounding air and transferring that heat into the stored water. This allows the system to produce hot water efficiently without relying only on direct electric element heating.
Rinnai states the AR Series can use more than 70% less energy than a standard electric water heater under stated conditions. Actual savings can vary depending on location, household usage, tariff setup, installation conditions, the system being replaced and how the product is operated.
R290 Refrigerant
The Rinnai Enviroflo AR Series 300L uses R290 refrigerant, with a listed refrigerant mass of 380g.
Rinnai describes R290 as a high-efficiency refrigerant with very low Global Warming Potential. This makes the AR Series a strong option for customers wanting a modern heat pump system with efficient refrigerant technology.
The refrigeration circuit and installation location must be treated according to manufacturer installation requirements and applicable standards.
Built-In Wi-Fi Control
The Rinnai Enviroflo AR Series 300L includes built-in Wi-Fi control for use with the SmartLife App.
This gives homeowners convenient control over system operation and can help manage heating around daily hot water demand, off-peak electricity windows or solar PV generation where suitable.
App use is optional and depends on network setup, compatible device access and third-party app availability.
Solar PV Compatibility
The Rinnai Enviroflo AR Series 300L Heat Pump can be networked with solar PV panel systems.
This can help households align water heating with daytime solar generation where the electrical setup, timer settings and household routine are suitable. The best setup depends on the solar system, tariff arrangement, household hot water use and installation conditions.
Off-Peak Operation Option
The Rinnai Enviroflo AR Series 300L can be set to run during off-peak periods where electricity cost is lower and the tariff setup is suitable.
This can help customers reduce running costs, especially when combined with smart timer control, suitable hot water demand and the right electrical setup.
Multiple Operating Modes
The Rinnai Enviroflo AR Series 300L includes multiple operating modes:
-
Standard
-
ECO
-
Hybrid
-
Electric
-
Vacation
This gives customers more flexibility to balance energy efficiency, recovery speed, electric boost operation and holiday periods depending on household routines and hot water demand.
Built-In Electric Element
The Rinnai Enviroflo AR Series 300L includes an inbuilt electric element to help maintain reliable hot water supply.
The factory wired electric element is listed at 2.4kW, while the refrigeration module input is listed at 1.2kW and total rated input is listed at 3.4kW.
This gives the system backup heating support when needed while allowing heat pump operation to do the main water heating work under suitable conditions.
Hardwired Electrical Connection
The Rinnai Enviroflo AR Series 300L is designed as a hardwired heat pump hot water system.
It is not a simple plug-in appliance. Electrical suitability must be checked before installation, and the system must be connected by an authorised person in accordance with electrical requirements.
Some sites may require electrical work, a dedicated circuit, isolator installation, compliance upgrades or other electrical add-ons depending on the existing setup.
Anti-Frost and Auto Disinfection
The Rinnai Enviroflo AR Series 300L includes built-in anti-frost protection to help protect the evaporator in colder climates.
It also includes an auto disinfection function designed to periodically raise water temperature as part of the system’s control logic. This helps support water hygiene and hot water system safety requirements.
Quiet Operation
The Rinnai Enviroflo AR Series 300L has a listed sound level of 45 dB(A).
This makes it a quiet residential heat pump option where site placement, clearances, neighbouring bedrooms, windows, fences and walls are still considered during installation.
Installed sound can vary depending on the final location, nearby surfaces and airflow conditions.
Standard and Hard Water Anode Options
The Rinnai Enviroflo AR Series 300L is available in standard and hard water anode versions.
The standard model is EHPA300VM. The hard water model is EHPA300VMH.
Choosing the correct version helps match the system to local water conditions. The right product depends on the property’s water quality, location and installation requirements.
Water Pressure and PLV Requirements
The Rinnai Enviroflo AR Series 300L is designed for water pressure conditions that must be checked before installation.
The PTR valve setting is listed at 1000 kPa / 10kW, with pressure limiting requirements depending on whether an expansion control valve is fitted.
Where an expansion control valve is fitted, a pressure limiting valve is required if mains pressure exceeds 680 kPa. Where an expansion control valve is not fitted, a pressure limiting valve is required if mains pressure exceeds 800 kPa. The recommended pressure limiting valve rating is 500 kPa.
STCs and Government Incentives
The Rinnai Enviroflo AR Series 300L Heat Pump may be eligible for Small-scale Technology Certificates where requirements are met.
Eligibility and value can vary depending on installation location, product model, installation date, installer requirements and program rules. Some state-based incentives may also apply where requirements are met.
Any rebate, STC discount or incentive should be confirmed before ordering or installation.
