AmbiPower 280e Heat Pump Water Heater

The AmbiPower® 280e is a cutting-edge 280-litre heat pump utilising R290 refrigerant, known for its low Global Warming Potential (GWP). Designed as a highly energy-efficient alternative to traditional electric water heaters, it offers a superior Coefficient of Performance (COP) of 5.2, making it an excellent solution for environments where solar water heating may not be ideal.

Key Features:

Advanced Microchannel Heating Technology: This product features a wrap-around microchannel heating system that ensures consistent and rapid water heating, even in challenging conditions.
Cold Climate Adaptability: Operates efficiently in temperatures ranging from -6°C to +43°C, making it suitable for various climates, including colder regions.
Corrosion-Resistant Design: Built with an enamel-lined water tank to minimise the risk of corrosion, it is perfect for areas with harsh water conditions.

Durable Construction: Housed in robust painted sheet metal with an aluminium top cover, this heat pump is engineered to withstand harsh Australian weather conditions.
Energy Savings: Based on TRNSYS modeling, it can deliver up to 73.9% energy savings compared to traditional electric water heaters in Zone 3.

Backup Heating Element: A 2.4 kW backup heating element ensures reliable performance in frigid climates.
User-Friendly Interface: Equipped with an LED touchscreen controller for easy operation and performance monitoring.

WHY CHOOSE A RHEEM HEAT PUMP?

AmbiPower® 280e Heat Pump has been designed and tested to withstand the harsh Australian conditions:

Enamel lined water tank for extended cylinder life and reduces the risk of corrosion.
Microchannel technology provides a larger contact area for more efficient water heating.
Side fan design provides maximum airflow and protects from the rain.
Durable outer shell in coated steel to reduce corrosion and withstand harsh weather conditions.
LED touchscreen controller provides optimum visibility, product performance information and user-friendly operation.
COP1 – The Coefficient of Performance for a Heat Pump is the ratio of how much useful heat it produces for water heating to the power input into the water heater. The higher the COP number, the more efficient the Heat Pump is.
Ambient Air Temperature and Humidity – The performance of a Heat Pump changes with ambient air temperature, humidity and incoming water temperature. The warmer the air temperature and the higher the Relative Humidity and the cooler the water temperature, then the higher is the heating rate of the Heat Pump. Performance specifications stated in relation to the Heat Pump are measured at predefined conditions during its testing.

Average Heating Capacity (kW) – This is how much heating power is put into the water during the heating cycle. It is expressed as an average due to the changes in heating power from the refrigeration cycle as the water is being heated and its temperature increases during the heating cycle.
Hot Water Recovery Rate @ 45°C rise (L/hr) – Is the number of litres of water that can be heated through a 45°C temperature rise in one hour, e.g. when the air temperature is 19°C, the Heat Pump can heat 56 litres / hour of water @ 45°C rise.
Global Warming Potential (GWP) – The Global Warming Potential (GWP) was developed to allow comparisons of the global warming impacts of different refrigerant gases. Specifically, it measures how much energy the emissions of 1 ton of a gas will absorb over a given period of time, relative to the emissions of 1 ton of carbon dioxide (CO2). The larger the GWP, the more that a given gas warms the Earth compared to CO2 over that time period. The time period usually used for GWPs is 100 years. GWPs provide a common unit of measure. GWP of common refrigerants used in heat pumps are R410 - GWP of 2088, R134a - GWP of 1430, R513a - GWP of 629, R290 - GWP of < 3 and CO2 - GWP of 1.

Built for Australian Conditions

The AmbiPower® 280e is designed to endure the harsh conditions often encountered in Australia. Its side fan design optimises airflow while protecting the unit from rain, and its construction ensures long-lasting durability and resistance to corrosion.

Energy Efficiency

The AmbiPower® 280e can dramatically lower energy consumption for hot water heating. By switching from an electric water heater, households in Zone 3 can achieve energy savings of up to 73.9%. This high-efficiency performance is complemented by using R290 refrigerant, which has a GWP of less than 3.
