Split System Advantages

The smarter way to heat water and your home — independently optimised for maximum efficiency and convenience.

Simultaneous Operation

Heat your home and water at the same time. No more waiting for hot water recovery while your house gets cold.

Faster Installation

Simple 13A plug connection. No complex piping to cylinder. Install hot water first, then space heating — keeping customers happy.

Right-Sized Systems

No oversizing heat pumps for hot water demand. Each system optimised for its specific task = better efficiency.

Lower Total Cost

Smaller space heating heat pump + dedicated water heater = lower overall system cost than an oversized single unit.

Perfect for Retrofits

No MCS required for water-only systems. Ideal for quick replacements and distress purchases.

Indoor Heat Recovery

Extract heat from indoor air before it leaks outside. Higher COP from 21°C source vs 5°C outdoor air.
