Solahart Atmos® Eco
Solahart Atmos® Eco 180 Heat Pump is the new generation 178 litre capacity renewable water heater, suitable for small families.
This is a smart, energy-efficient alternative for areas where a conventional solar water heater may not be suitable. It uses the heat from the surrounding air and doesn’t rely on direct sunlight to heat your water, providing a reliable, efficient, and sustainable way to reduce your water heating energy consumption.
The advanced wrap-around microchannel heating technology for uniform and faster water heating makes it suitable for cold climates with an operating range from -7°C to 43°Cr ambient temperatures.

Solahart Atmos® Eco: Key Attributes
Enamel Lined Water Tank
The enamel coating and steel plate technology reduce the risk of corrosion and water leakage.
Touchscreen LED Controls
A bright interactive LED touchscreen display putting control at your fingertips.
Side Fan Design
There is an incentive resulting in a financial benefit to households that install solar hot water, under the Renewable Energy Target – a Federal Government legislated scheme. Your Solahart Expert can deduct the value of the financial benefit as an upfront discount off your system.
WHY ATMOS FROST IS A SMART CHOICE
A Solahart Atmos® Eco 180 Heat Pump is the smart choice for people who are looking for an energy-efficient alternative to a small to medium-sized electric water heater but are unable to install a solar water heater. It heats water by drawing heat from the surrounding air, is a reliable and efficient way to reduce energy consumption and cut greenhouse gas emissions, and is a sustainable way to reduce your water heating energy consumption without the need for rooftop solar collectors.
User-Friendly LED Controller Display: For easy operation.
High COP OF 4.5: Coefficient of Performance (COP) of 4.5@ 19oC.1
Government Incentives: Eligible for STCs (may be eligible for additional incentives in some states).
Suitable for cold climates: With an operating range from -7°C to +43°C. It is also suitable for harsh water conditions.
Can save up to 70% on your water heating energy use: when compared to an electric water heater in Zone 3.2
Microchannel Technology: Provides a larger contact area to maximise heat transfer efficiency. The advanced wraparound design provides uniform and faster water heating.

2 Energy savings of up to 70% in Zone 3 based on TRNSYS modelling on hot water energy consumption when replacing an electric water heater (min 16 hours/day). Any savings will vary depending upon your location, type of water heater being replaced, hot water consumption and fuel tariff.
How Heat Pump Water Heaters Work
The efficient heat pump technology extracts energy from the surrounding air. Ambient warmth is used to convert the refrigerant within the sealed system into a gas. The gas is then compressed to generate even more heat, which then heats the water in the tank. What’s more, this process can work day or night, in sunshine and rain, all year round.
When hot water is drawn off, and cold water enters the tank, the thermostat activates the fan and the compressor. The operation of the compressor causes a pressure difference within the sealed refrigeration system. This pressure difference causes the refrigerant to move around the sealed system. The refrigerant enters the evaporator as a liquid. As the refrigerant absorbs heat from the atmosphere, it changes state, at low pressure, from a sub-cooled liquid to a super-heated vapour or gas (evaporates). The vapour then enters the compressor and obtains more heat, known as heat of compression, and passes into the heat exchanger as a super-heated vapour at high pressure.
As the refrigerant passes through the microchannel heat exchanger wrapped around the storage cylinder, it gives off heat, which is absorbed by the water inside the cylinder. As the refrigerant gives off heat, it cools and changes state back into a liquid (condenses). The refrigerant then enters the evaporator again, and the cycle is repeated. The resulting cold air is then discharged through the air outlets back into the atmosphere. This process continues whenever heating is required until the water in the storage tank reaches its hot water temperature set point.
