Answer a few quick questions and we will tell you whether you can continue ordering online now or need the 60sec Check first.

Are you replacing an existing hot water system?
This helps us work out whether this looks like a standard replacement or may need extra parts.
Are you replacing the same hot water system, identical make and model?
If yes, the valve kit will be recommended. If not, it will be required at the end.
Is it going in an existing location?
Existing location means the new system is going back into the same general installed position.
Where is the system located?
If it is outside, continue. If it is inside or under a house, the 60sec Check must be completed first.
Are you changing system type, electrical connection type or needing to extend your electrical connection?
If yes, we will advise at the end that an electrical extension or new circuit may be needed, or you can organise your own electrician.
Do any site access issues apply?
If any access issue applies, direct them to the 60sec Check first. If none apply, continue with the form.
Does your current installation meet current compliance requirements?
If no or unsure, we will recommend a valve kit or additional works as the safer starting point.

      The Rinnai Enviroflo GR Series 280L heat pump is a larger-capacity electric integrated heat pump hot water system designed for family homes wanting lower energy use than a standard electric storage tank. With 280L tank volume, R290 refrigerant, built-in Wi-Fi control, solar PV compatibility, 2.4kW electric boost element, 46 dB(A) quiet operation, and sizing for up to 5 people, it is a strong upgrade option for replacing a medium to large electric hot water system.

      About the Rinnai Enviroflo GR Series 280L Heat Pump

      The Rinnai Enviroflo GR Series 280L 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 practical amount of hot water for daily family use.

      The 280L GR Series model is designed for households needing more capacity than a 215L heat pump, while still being slightly smaller than the 300L GR Series option. It can suit family homes, townhouses, rental properties and households with moderate to higher daily hot water demand.

      Order the Rinnai Enviroflo GR Series 280L 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.

      280L Heat Pump Storage

      The 280L tank volume makes the Rinnai Enviroflo GR Series 280L a strong family heat pump option.

      It gives more stored hot water than the 215L model and can suit households that need more daily hot water capacity without moving to the 300L GR Series option. This makes it a practical fit for families, larger townhouses, rental homes and properties with moderate to higher hot water demand.

      For lower-demand homes, the 215L model may be enough. For larger households, the 300L model may be more suitable.

      Efficient Heat Pump Hot Water

      The Rinnai Enviroflo GR Series 280L 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 GR 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 GR Series 280L uses R290 refrigerant.

      Rinnai describes R290 as a high-efficiency refrigerant with a very low Global Warming Potential of 0.02. This makes the GR Series a strong option for customers wanting modern heat pump technology with efficient refrigerant performance.

      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 GR Series 280L 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 GR Series 280L 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 GR Series 280L 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 GR Series 280L 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.

      2.4kW Electric Boost Element

      The Rinnai Enviroflo GR Series 280L includes a 2.4kW factory wired electric element.

      The electric element helps maintain reliable hot water supply when boost heating is required, while the heat pump provides the main water heating function under suitable conditions.

      This gives the 280L model strong backup support for family homes where daily hot water demand can vary.

      15 Amp Plug Fitted

      The Rinnai Enviroflo GR Series 280L is supplied with a 15 amp plug fitted and can also be hardwired where suitable.

      This is important because it is not the same as a standard 10 amp plug-in appliance. Electrical suitability should be checked before installation, and some sites may require electrical work, a dedicated circuit, power point changes, compliance upgrades or hardwired connection depending on the existing setup.

      Anti-Frost and Auto Restart

      The Rinnai Enviroflo GR Series 280L includes built-in anti-frost protection to help protect the evaporator in colder climates.

      It also includes auto restart, meaning the unit can restart automatically once power is restored after a power outage. These features help support reliability across different operating conditions.

      Auto Disinfection Function

      The Rinnai Enviroflo GR Series 280L includes an auto disinfection function.

      This function is designed to help reduce the potential growth of legionella by periodically raising water temperature as part of the system’s control logic.

      Quiet Operation

      The Rinnai Enviroflo GR Series 280L has a listed sound level of 46 dB(A).

      This makes it a practical 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.

      Water Pressure and PLV Requirements

      The Rinnai Enviroflo GR Series 280L 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 GR Series 280L 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.

      Rinnai Enviroflo GR 215L vs GR 280L

      The Rinnai Enviroflo GR Series 280L gives more stored hot water than the GR Series 215L.

      The 215L model is sized for up to 4 people and can suit smaller families or moderate-demand homes. The 280L model is sized for up to 5 people, making it better suited to family homes with higher daily hot water use.

      The 280L model also uses a 15 amp plug setup, so electrical suitability should be checked before installation.

      Rinnai Enviroflo GR 280L vs GR 300L

      The Rinnai Enviroflo GR Series 300L provides slightly more storage capacity than the 280L model and is sized for up to 6 people.

      The 280L model can suit households up to 5 people, while the 300L model may be better where the household has higher daily use, longer shower habits or wants the extra buffer of the largest GR Series option.

      The better choice depends on household size, shower length, tariff setup, available space, installation access and electrical requirements.
