The Rinnai Enviroflo 300L GR Series uses R290 — a natural, low global warming potential refrigerant — to deliver exceptional hot water efficiency. Designed for whole-home supply with up to 1000kPa water pressure rating.
With a COP of up to 7.5, the Enviroflo 300L GR Series delivers exceptional heat pump efficiency. Every $1 of electricity produces up to $7 of heating value, slashing hot water running costs.
R290 has one of the lowest global warming potentials of any refrigerant in use today. It’s efficient, eco-friendly, and future-proofed against regulatory changes affecting older refrigerants.
Rated for water supply pressures up to 1000kPa — compatible with most Australian mains water supplies without the need for a pressure-limiting valve.
Designed for Australian conditions, the Enviroflo operates effectively across a wide ambient temperature range — delivering hot water reliably all year round, even in cooler climates.
Qualifies for federal Small-scale Technology Certificates significantly reducing your upfront cost. We handle all the paperwork and pass the saving directly to you.
Rinnai has been trusted by Australian homeowners for decades. WaterMark certified, backed by a national service network, and designed for Australian conditions.
The Enviroflo extracts heat from the surrounding air and transfers it to your water — rather than generating heat from scratch. This process uses 3–4× less electricity than a conventional electric system, making it one of the most cost-effective ways to heat water.
The Rinnai Enviroflo 300L GR Series is backed by a 7-year warranty from Rinnai Australia, covering the storage cylinder and heat exchange components. Must be installed by a licensed tradesperson.
The Enviroflo 300L GR Series uses Rinnai’s inverter-driven compressor tuned for quiet, year-round residential operation. Anti-vibration base mounts isolate the compressor from the structure, keeping noise below 52 dB in all conditions — from midwinter mornings to summer afternoons.
The Enviroflo 300L GR uses Rinnai’s proven vitreous enamel cylinder with sacrificial magnesium anode — reliable corrosion protection across all Australian water types and climate zones. Backed by a 10-year cylinder warranty and Rinnai’s national service network.
