Why Choose This System

Split System Flexibility — Heat Pump Outside, Tank Inside

The Rinnai Enviroflo S Series puts the heat pump unit outside and the storage tank where you need it — reducing noise inside the home and giving you maximum installation flexibility.

Up to 75% Less Energy

By extracting heat from outside air rather than generating it from scratch, the Enviroflo split system delivers 3–4× more hot water per dollar than a conventional electric storage system.

🔉

Quiet Split System Design

The 7.0kW heat pump unit is installed outside, keeping compressor noise away from living areas. The storage tank can be positioned inside a cupboard or utility room for convenience.

☀️

Solar PV Compatible

The S Series is designed to work seamlessly with solar PV systems — schedule heating during solar generation hours and make the most of your rooftop energy.

💧

7.0kW Output

A 7.0kW heat pump provides robust hot water recovery, ensuring your hot water is replenished quickly after high-demand periods.

Outdoor Pump, Indoor Tank

The Enviroflo S Series separates the heat pump from the storage tank. The outdoor unit captures heat from outside air; the tank stores your hot water where it’s most convenient — inside a cupboard, bathroom, or utility room.

  • Heat pump unit mounted outdoors — minimal indoor footprint
  • Flexible tank placement inside the home
  • Reduced compressor noise indoors
  • Solar PV compatible for maximum savings

Compressor Outside — Tank Inside

The Enviroflo S7.0kW Split puts the 7kW compressor unit outdoors and the 400L storage tank inside — giving you the best of both worlds. The indoor tank is completely silent. The outdoor unit operates below 52 dB and can be positioned away from bedroom windows with flexible piping runs.
