Running Costs
Heat Pump Systems
More energy-efficient, annual running costs are estimated at $280, resulting in $2,800 over ten years. Efficiency is due to the heat pump's ability to extract heat from the air, reducing electricity consumption.
Electric Storage
Annual running costs are about $970, leading to $9,700 over ten years.
Gas Storage
Yearly expenses are approximately $570, totalling $5,700 over a decade.
Environmental Impact
Heat Pump Systems
Comparable to gas storage, with about 8 tonnes of CO₂ emissions over ten years
Electric Storage
Approximately 28 tonnes of CO₂ emissions over ten years.
Gas Storage
Around 8 tonnes of CO₂ emissions in the same period.
Total Upfront + Running Cost Over 10 Years
Heat Pump Systems
$4,200 (upfront) + $2,800 (running) = $7,000
Electric Storage
$1,600 (upfront) + $9,700 (running) = $11,300
Gas Storage
$2,000 (upfront) + $5,700 (running) = $7,700

SHP-O 200 & SHP-O 300 – Smart, Sustainable Hot Water Systems
The SHP-O series offers an advanced heat pump hot water system with intelligent control, solar compatibility, and an eco-friendly R290 refrigerant for a lower carbon footprint.
User-friendly controls feature three simple buttons for boost, pairing, and emergency modes, along with LED status indicators for easy monitoring. For added convenience, remote operation is available via smartphone or tablet, including hot water boost functionality.
Designed for quiet operation, these models have no compressor in the airflow and feature optimised recirculation air mode. They also utilise the eco-friendly natural refrigerant R290 and seamlessly integrate with photovoltaic systems, enabling homeowners to use self-generated solar energy.
Fault notifications are sent via the app, enabling direct contact with contractors or activation of emergency mode if needed. Additionally, the app tracks runtime performance, helping users monitor efficiency over time.
Users can also set the minimum stored mixed water amount, improving energy efficiency and convenience. The SHP-O 300 and SHP-O 200 Plus heat pumps provide a reliable, efficient, and eco-friendly domestic hot water heating solution—ideal for modern homes looking to save energy, enhance comfort, and eliminate the need for additional heating sources.
