HEAT PUMP
Horizontal Split System — Rooftop or Ground Level
Neopower's horizontal split heat pump is designed for properties where space is at a premium. Install the low-profile tank flat on the roof or at ground level — the perfect solution for townhouses, apartments, and compact blocks.
The Smart Solution for Space-Constrained Properties
Whether you mount it on the roof or lay it flat at ground level, the Neopower horizontal split heat pump is engineered for properties where a conventional upright system simply doesn't fit. Urban homes, townhouses, apartments — this system was designed with your constraints in mind.
6 Reasons to Choose Rooftop Mounting
Whether you're retrofitting an existing property or specifying for new construction, rooftop heat pump installation delivers measurable benefits across every dimension.
Space Optimisation
Rooftop installation is ideal for urban settings and compact homes where yard or balcony space is limited. Studies indicate that utilising rooftops can free up to 30% of ground-level area — reclaim your outdoor space for landscaping, entertaining, or storage.
Noise Reduction
Positioning the heat pump on the roof increases the distance between the compressor and indoor living areas such as bedrooms and offices. The roof structure itself acts as a natural sound barrier, contributing to a significantly quieter indoor environment.
Enhanced Performance
Elevated heat pumps benefit from better unrestricted airflow and more consistent ambient temperatures due to fewer obstructions. This improved air supply can result in up to 20% energy savings compared to ground-mounted systems.
Increased Security & Durability
Roof-mounted units are far less accessible to thieves and vandals. They are also protected from ground-level hazards such as debris, dust, and accidental damage from foot traffic or yard work — all of which can extend the system's service lifespan.
316 Stainless Steel Longevity
Our tanks use 316 Grade Stainless Steel — widely regarded as the gold standard for hot water storage due to exceptional corrosion resistance and long service life. Backed by a 10-year parts warranty on the cylinder.
Aesthetic Preservation
For properties with strict aesthetic guidelines or strata rules, a roof-mounted unit is far less visible from street level, helping to maintain the building's architectural character while still delivering modern hot water performance.

Rooftop or Ground Level — Your Choice
The Neopower horizontal split heat pump isn't limited to rooftops. The same low-profile system can be installed flat on the ground — ideal for townhouses, units, and homes where yard space exists but a standing upright tank doesn't fit the space or aesthetic.
Unlike conventional vertical all-in-one heat pumps that require significant clearance around them, the horizontal tank lays flat beside the wall — taking up minimal floor space and staying well below fence and window lines.
How the Rooftop Heat Pump Works
A heat pump doesn't generate heat — it moves it. By extracting thermal energy freely available in the surrounding air, the system delivers exceptional efficiency that a conventional electric heater can never match.
- 1
Air Drawn Across the Evaporator
A fan draws ambient air across the evaporator coil inside the condenser unit. Even at temperatures as low as -7°C, there is still useful heat energy in the air.
- 2
Refrigerant Converts to Gas
The evaporator absorbs heat from the air, causing the liquid R32 refrigerant to evaporate into a low-pressure gas — capturing that heat energy.
- 3
Compressor Raises the Temperature
The compressor pressurises the refrigerant gas, raising its temperature significantly into a hot, high-pressure state ready for heat transfer.
- 4
Heat Transfers to Tank Water
The hot refrigerant gas passes through the heat exchanger, transferring its energy to water circulating from the storage tank — heating it to 60°C.
- 5
Refrigerant Returns to Liquid
After giving up its heat, the refrigerant condenses back to a liquid and returns to the evaporator, repeating the cycle continuously and efficiently.
From just 1 kW of electricity, a heat pump can produce over 4 kW of useful heating energy — a performance efficiency of approximately 400%. Conventional electric storage heaters convert just 1 kW in to a maximum of 1 kW out.
Energy Flow
Refrigerant: R32
The Neopower Rooftop Heat Pump uses R32 refrigerant — a modern HFC with a significantly lower Global Warming Potential (GWP of 675) than the older R410A (GWP of 2088). This means a more environmentally responsible system without compromising efficiency or performance.
