Frequently asked.
Everything you wanted to know, in one place. Switch between heat pumps and air conditioning.
What is an Emerald All-in-One Heat Pump and how does it work?
An Emerald All-in-One Heat Pump uses ambient air to heat water efficiently, using significantly less electricity than traditional electric storage or gas hot water systems. The heat is extracted from the air and transferred to the water tank, which is why heat pumps can deliver up to four times more heat energy per unit of electricity than a standard electric water heater.
How much can an Emerald All-in-One Heat Pump reduce energy bills?
Most households can reduce hot water energy costs by up to 80% with an Emerald All-in-One Heat Pump, depending on usage and existing system. The savings come from the heat pump's superior coefficient of performance (COP) — Emerald systems can hit a COP of up to 4.41.
Is the Emerald All-in-One Heat Pump suitable for Australian climates?
Yes. Emerald All-in-One Heat Pumps are designed to perform efficiently in Australian conditions, including cooler mornings and winter temperatures. Select models operate from as low as –7 °C (and –15 °C in some configurations) up to +46 °C ambient.
Are rebates available for Emerald All-in-One Heat Pumps?
Yes. Eligible households may qualify for multiple rebates: the Solar Victoria Hot Water Rebate (up to $1,000), the Victorian Energy Upgrades (VEU) program, Federal STCs, and Victorian Energy Efficiency Certificates (VEECs). We handle eligibility checks and applications.
Is the Emerald All-in-One Heat Pump noisy?
No. Pro models (220 Pro, 270 Pro, 320 Pro) run at 39 dB — comparable to light rain. Select models (270 Select, 320 Select) operate at 41 dB.
How long does Emerald All-in-One Heat Pump installation take?
Most installations are completed within a couple of hours* by our licensed plumbers and electricians. We handle removal of the old system and certification. (*Typical install time. Actual time varies by site conditions.)
What's the warranty on the Emerald All-in-One Heat Pump?
Every Emerald All-in-One Heat Pump comes with up to a 7-year warranty on the system (tank and refrigeration components) and a 2-year labour warranty.
Can I monitor my Emerald All-in-One Heat Pump remotely?
Yes. Every Emerald All-in-One Heat Pump includes built-in Wi-Fi and the Emerald App. You get usage tracking, scheduling, and remote control over heating modes from your phone.
Are Emerald air conditioners reverse cycle?
Yes. Every Emerald air conditioner — Ducted Ultra, Ducted Pro, and Multi-Head models — is reverse cycle. That means heating in winter and cooling in summer, all from one system.
What's the difference between Ducted and Multi-Head systems?
Ducted systems push conditioned air through ductwork in your ceiling to cover the whole home or zoned areas. Multi-Head systems use one outdoor unit connected to multiple wall-mounted indoor units (one per room) — letting you heat or cool only the rooms you're using.
Are rebates available when replacing gas heating with reverse cycle?
Yes. Switching from a gas ducted system to electric reverse cycle is one of the most rewarding rebate scenarios. VEU rebates can range from $2,450 to $5,180 depending on system size and your current setup. We handle eligibility and applications.
What's VRF technology?
Variable Refrigerant Flow. The system optimises refrigerant delivery to indoor units based on real-time demand, which means more efficient operation and tighter temperature control across multiple zones.
Will an Emerald aircon handle Melbourne summers and winters?
Yes. Emerald systems are engineered for Australia's climate extremes — heat waves and cold mornings. They use a wide operating temperature range and DC dual-rotor compressors for stable performance across voltage fluctuations.
How does Eco Mode work?
Eco Mode reduces power consumption by up to 30% without compromising comfort. It moderates compressor cycling for steady, efficient operation.
Can I control my Emerald aircon from my phone?
Yes. Every Emerald aircon system supports the Emerald App via AC Link — for scheduling, temperature automation, and remote control.
