Enviroflo GR Series Heat Pump
Enviroflo GR Series Heat Pump
The Rinnai Enviroflo GR Series Electric Integrated Heat Pump hot water systems are your reliable choice for efficient hot water. Designed to meet a variety of installation needs across Australia, the GR Series offers capacities of 215L, 280L and 300L, making it suitable for diverse site requirements.
Featuring as standard a single element boost, you can enjoy hot water comfort, anytime. The GR Series is PV compatible, allowing for integration with solar energy systems to enhance efficiency.
Built to withstand Australia’s tough climate, these systems operate effectively under water pressures up to 1000kPa, ensuring durability and dependable performance. Plus, they utilise R290, an environmentally friendly refrigerant, making them a sustainable choice for your hot water needs.
Available in 215L, 280L and 300L capacities
Designed to operate quietly
Built in Wi-Fi for convenient control
Can be networked with solar PV
Enviroflo GR Series Heat Pump
- Innovative controller to maximise hot water availability while using more than 70% less energy*
- High efficiency R290 refrigerant with a low Global Warming Potential of just 0.02.
- Multiple operating modes (Standard/ECO/Hybrid/ Electric/Vacation).
- Operates in ambient air conditions ranging from -7°C to 45°C.
- Designed and built with a high level of product quality, backed by over 50 years of Rinnai’s excellence in hot water.
- Built in anti-frost function to protect the evaporator in colder climates.
- Inbuilt electric element to ensure you always have a reliable supply of hot water.
- Auto disinfection preventing the potential growth of legionella.
- Auto restart function - in the event of a power outage it will automatically restart once the power is re-instated.
- Option to run only at off-peak times, when the electricity cost is lower.
*Energy saving based on a Rinnai Enviroflo GR Series Heat Pump when compared to a standard electric water heater of the same capacity during peak winter load in Zone 3 and 4 based on AS/NZS4234. Savings will vary depending on location (Zone 1-5), type of water heater being replaced, hot water consumption and associated fuel tariffs.
Federal Small-Scale Technology Certificate (STC’s)
Enviroflo’s innovative design allows it to be eligible for Grants through the Federal Government’s Small-Scale Renewable Energy Scheme, generously covering a proportion of the up-front costs of purchasing and installing the system. These grants are called Small-Scale Technology Certificates (STCs) and are offered based on how sustainable a hot water system is. Your STC rebate value will depend on your installation location, see the map above for your geographic zone locations.

State Grants
Victoria
For Victorian consumers there are additional rebates available for replacing inefficient hot water systems with Heat Pumps. Victorian Energy Efficiency Certificates (VEECs) are offered for eligible installations on top of the Federal STC grants - making the conversion to a Rinnai Enviroflo Heat Pump the obvious low-cost choice.
New South Wales
For New South Wales consumers there are additional rebates available for replacing inefficient hot water systems with Heat Pumps. Energy Savings Certificates (ESCs) are offered for eligible installations on top of the Federal STC grants - making the conversion to a Rinnai Enviroflo Heat pump the obvious low-cost choice.
*The value of STCs and State Grants are a tradable, market driven commodity. Values are subject to daily variation and are valid as of 16.10.2024
