Rinnai's Enviroflo S Split Electric Heat Pump
The Rinnai Enviroflo S Split Electric Heat Pump
The Rinnai Enviroflo S Split Electric Heat Pump offers efficient and reliable hot water solutions for Australian homes. Available in 250L, 315L and 400L capacities, it caters to various household sizes and hot water demands. With a powerful 7.0kW heat pump, it ensures consistent hot water supply even during peak usage or colder weather conditions.
Utilising advanced heat pump technology, the Enviroflo S delivers high energy efficiency, reducing electricity consumption and lowering energy bills. Designed for residential and light commercial applications, the system operates quietly, ensuring minimal noise disruption. Built to withstand Australia's harsh climate, the Enviroflo S is constructed with high-quality materials to ensure long-lasting performance.
The split system design separates the heat pump from the storage tank, allowing for flexible installation options, accommodating various site requirements and configurations, and simplifies maintenance. The system uses R290, a sustainable refrigerant, with low GWP (Global Warming Potential) aligning with environmental standards and reducing greenhouse gas emissions. Capable of handling water pressures up to 1000kPa, it ensures robust performance across different water supply systems.
The Enviroflo S Split Electric Heat Pump is an ideal choice for homeowners seeking a reliable, energy-efficient, and environmentally friendly hot water solution.

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.
Here's how the system works:
- 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.
- Heat is Captured: The evaporator transfers thermal energy from the air into the refrigerant, which turns into a warm gas as it absorbs heat.
- 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.
- 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.
A visual representation shows different refrigerants and their Global Warming Potential (GWP): R290 (GWP=0.02), R32 (GWP=675), R410A (GWP=2087), and R134A (GWP=1430). R290 is highlighted as having the lowest GWP.

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.
A map of Australia is divided into 5 zones (1-5) indicating different STC values based on location.
