Features and Benefits

Design & Installation

• Multiple Capacities: Available in 250L, 315L & 400L capacities to suit your hot water needs.
• Quiet Operation: Operates quietly down to a low 45dB(A), quieter than the average noise level of a household dishwasher.

Performance & Efficiency

• Energy Efficient: Using up to 70% less energy to heat your water than a standard electric storage tank.*
• Reliable: Inbuilt electric boost element to ensure you always have a reliable supply of hot water.

Sustainability

• Environmentally Focused: High efficiency R290 refrigerant with a low GWP of just 0.02.

Technology & Control

• Built in Wi-Fi: The built-in Wi-Fi module allows for convenient control from anywhere.
• Auto Disinfection: Auto disinfection preventing the potential growth of legionella.

Climate Readiness

• Adaptable for All Climates: Operates in ambient air conditions ranging from -10°C to 45°C.
• Defrost Control: Built-in anti-frost function to protect the evaporator in colder climates.

Additional Features

• Choice: Standard and hard water anode water tank options available.
• Locally Made: The Enviroflo S tanks are proudly designed, engineered and built in Australia.
• Versatile: Multiple operating modes (Standard/ECO/Hybrid/Electric/Vacation).
• Off-Peak Compatible: Option to run only at off-peak times, when the electricity cost is lower.
• PV Compatible: Can be networked with solar PV for enhanced efficiency and savings.
• Automated: Auto restart function means in the event of a power outage it will automatically restart once the power is re-instated.

*Energy saving based on a Rinnai Enviroflo S Split Electric Heat Pump (7.0kW) 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.

How Our Split Heat Pumps Work

The Rinnai Enviroflo S uses advanced heat pump technology to heat your water using energy from the air, not direct electricity. This makes it a highly efficient, low-emission solution for everyday hot water use.

System Operation

1. Air is Drawn In: A quiet efficient DC fan draws in ambient air across the evaporator coil in the external compressor unit. Even in cool conditions, the system can extract usable heat from the air.
2. Heat is Captured: The evaporator transfers thermal energy from the air into the refrigerant, which turns into a warm gas as it absorbs heat.
3. Compressor Boosts the Heat: The refrigerant gas is compressed, rapidly increasing its temperature. This is the core of the heating cycle, converting low-level heat into usable energy.
4. Transfers Heat to the Water: The hot refrigerant flows through a double wall heat exchanger located inside the heat pump, where it safely transfers its heat to the water.

R290 Refrigerant

This sustainable and non-toxic refrigerant has a zero Ozone Depletion Potential (ODP) and a GWP of just 0.02, which is 50 times less than CO2. As such, it easily outperforms other heat pumps that typically use refrigerants with high GWP values.

Refrigerant GWP Comparison:

• R290: GWP=0.02
• R32: GWP=675
• R134A: GWP=1430
• R410A: GWP=2087

Government Grants

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.

Geographic Zones Map: The map of Australia indicates five zones used for calculating STC rebate values based on installation location.

STC Rebate Values

*The value of STCs and State Grants are a tradable, market driven commodity. Values are subject to daily variation and are valid as of 25.06.2025

State Rebates

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 S Split Electric 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 Enviroflo S Split Electric Heat Pump the obvious low-cost choice.
