About the Rheem Stellar 360 Natural Gas Water Heater

The Rheem Stellar 360 Gas Water Heater is the larger model in Rheem’s premium Stellar gas storage range. It is designed to deliver stored hot water with very fast recovery as hot water is used.

Unlike a gas continuous flow unit, the Stellar 360 stores hot water in a cylinder and recovers the tank using natural gas. This makes it a practical option for customers who prefer the familiar performance of a storage water heater but want stronger recovery and better gas efficiency than many older gas storage systems.

The Rheem Stellar 360 is designed for outdoor installation and is commonly selected for larger family homes replacing an existing external natural gas storage hot water system.

Natural Gas Storage Hot Water

This product is the natural gas version of the Rheem Stellar 360 gas storage water heater.

It is designed for properties connected to natural gas. The correct gas type must be selected before ordering or installation, as natural gas and LPG systems are not interchangeable without selecting the correct product and completing suitable licensed gas work.

If your current water heater is connected to natural gas, this product is the correct gas type pathway.

360L First Hour Capacity

The 360L first hour capacity is one of the key reasons customers choose the Rheem Stellar 360.

First hour capacity combines stored hot water with the unit’s recovery performance. This helps the system deliver a large amount of usable hot water over the first hour, which can be useful for larger households where multiple showers, kitchen use and laundry demand may happen close together.

This makes the Rheem Stellar 360 a strong choice for homes where hot water recovery matters.

200L/Hour Hot Water Recovery

The Rheem Stellar 360 is designed with superior hot water recovery, listed at 200L/hour.

Fast recovery helps the water heater replace hot water as it is used, reducing the chance of running out during normal household routines. This is especially useful for larger family homes, rental properties and homes where several people use hot water in a short period.

5 Star Gas Efficiency

The Rheem Stellar 360 has a 5 Star gas energy efficiency rating, making it more efficient than many older 3 Star and 4 Star gas storage water heaters.

This can help reduce gas use compared with older, less efficient storage systems. Actual running costs still depend on household hot water use, natural gas pricing, thermostat settings, climate, installation condition and how the system is used.

Rheem Superflue® Technology

The Rheem Stellar 360 includes patented Rheem Superflue® technology, designed to support strong performance and high gas storage efficiency.

This is a major feature that helps position the Stellar 360 as a premium gas storage hot water system rather than a basic replacement unit.

Mains Pressure Hot Water

The Rheem Stellar 360 Gas Water Heater provides mains pressure hot water, helping deliver strong flow to multiple taps where the property’s plumbing and pressure conditions are suitable.

This makes it a practical option for family homes where more than one hot water outlet may be used across the home.

Outdoor Installation Only

The Rheem Stellar 360 Natural Gas Water Heater is designed for outdoor installation.

It should not be installed internally. Gas hot water systems must be installed in accordance with manufacturer instructions, gas fitting rules, ventilation requirements, clearance requirements and local compliance standards.

Stellar 330 vs Stellar 360

The Rheem Stellar 360 is the larger option compared with the Rheem Stellar 330.

The Stellar 330 has a 130L storage capacity and 330L first hour capacity, while the Stellar 360 has a 160L storage capacity and 360L first hour capacity. Both models have 200L/hour recovery and 5 Star gas energy efficiency, but the Stellar 360 gives more stored capacity and higher first hour hot water output.

For larger families or higher hot water demand, the Stellar 360 may be the better choice. For smaller households that still want premium high-recovery gas storage, the Stellar 330 may be suitable.

Common Uses

The Rheem Stellar 360 Natural Gas Hot Water System can be suitable for:

• natural gas storage hot water replacement

• outdoor gas storage installations

• larger family homes

• townhouses

• rental properties

• investment homes

• properties replacing older gas storage units

• homes wanting mains pressure gas storage hot water

• homes needing strong first hour capacity

• homes needing fast gas storage recovery

• customers wanting a premium Rheem gas storage model

• customers wanting more capacity than the Rheem Stellar 330
