Description
Rinnai 250L S7.0kW SplitSplit Heat Pump Hot Water
Perfect for 2–4 people. The Rinnai Enviroflo 250L S7.0kW Split is a high-performance 7.0kW split system heat pump — separating the outdoor unit from the storage tank for flexible, quiet installation. Backed by a 7-year warranty.
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

- Flexible tank placement inside the home

Compressor Outside — Tank Inside
The Enviroflo S7.0kW Split puts the 7kW compressor unit outdoors and the 250L 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.
- Split system design — compressor unit stays outdoors
- Indoor storage tank is completely silent — no mechanical noise inside
- Outdoor unit below 52 dB — position away from living areas
- Flexible piping runs let you optimise placement for noise and access
- Timer scheduling for off-peak heating overnight

Enamel-Lined Cylinder — Indoor Protected
The Enviroflo Split’s 250L indoor cylinder is vitreous enamel lined with sacrificial anode protection — and because it’s installed indoors, it’s shielded from external UV, rain, and temperature extremes that degrade outdoor tanks. Backed by Rinnai’s 10-year cylinder warranty.
- Vitreous enamel glass-lined cylinder — corrosion barrier
- Sacrificial magnesium anode — continuous tank protection
