PRODUCT OVERVIEW
What Is the Rheem Ultra 28L Gas Continuous Flow Water Heater 50°C Preset?
The Rheem Ultra 28L Gas Continuous Flow Water Heater 50°C Preset is a natural gas hot water appliance designed to produce heated water as it passes through the unit.
Unlike a conventional storage system, it does not maintain a large cylinder of stored hot water. Instead, it responds to hot water demand and heats water during use.
The 28L designation identifies it as a higher-capacity continuous flow model. That makes it relevant to larger homes and households where several hot water outlets may be used during busy periods.
The model is specifically identified as a 50°C preset version. This is an important distinction when comparing it with other temperature configurations in the Rheem range.
Although the appliance is positioned for higher demand, the exact amount of hot water available depends on its verified manufacturer rating, the incoming water temperature and the desired outlet temperature.
JR Gas & Water recommends assessing the home's actual requirements rather than choosing a system solely by its nominal litre rating.
Why Choose the Rheem Ultra 28L 50°C Preset?
High-Capacity Hot Water
The 28L capacity class is aimed at households needing greater hot water delivery than smaller instantaneous systems.
On-Demand Heating
Water is heated as it is used, rather than relying on the available volume of a conventional storage cylinder.
50°C Preset Configuration
The factory preset version provides a defined outlet temperature arrangement for suitable domestic applications.
Space-Saving System Type
Continuous flow heating avoids the floor space required by a large conventional storage tank.
Potential for Simultaneous Use
A larger capacity class may better accommodate several hot water outlets operating together.
Recognised Manufacturer
Rheem is an established hot water brand, with model-specific warranty and support conditions to be confirmed.
HOUSEHOLD SUITABILITY
Who Is the Rheem Ultra 28L 50°C Preset Best Suited To?
The Rheem Ultra 28L 50°C Preset may be appropriate for larger homes with substantial hot water requirements.
It is particularly relevant where the household regularly uses more than one hot water outlet at the same time.
Homes It May Suit
Larger family homes
Multiple-bathroom properties
Households with busy morning routines
Homes with greater simultaneous hot water demand
Properties already connected to natural gas
Existing high-capacity continuous flow replacements
Homes seeking a tankless gas hot water system
Properties suitable for a 50°C preset configuration
Important Suitability Checks
Actual household hot water demand
Number of showers used simultaneously
Showerhead and fixture flow rates
Natural gas supply availability
Gas meter and pipework capacity
Water pressure and flow
Manufacturer-approved installation position
Required hot water delivery temperatures
A larger appliance is not automatically the best choice for every home. Correct sizing should account for expected demand, installation costs and the existing services.
Is the Rheem Ultra 28L Suitable for Multiple Bathrooms?
The Rheem Ultra 28L is positioned for higher hot water demand and may be a suitable option for homes with multiple bathrooms.
However, bathroom count alone does not determine the required appliance size.
A home with three bathrooms but only one shower used at a time may have a different demand profile from a two-bathroom home where both showers operate together every morning.
Showerhead flow rates, the desired water temperature and other simultaneous uses should all be considered.
JR Gas & Water can help assess whether the Rheem Ultra 28L is an appropriate capacity for the home's normal usage.
Can the Rheem Ultra 28L Run Two Showers at Once?
The Rheem Ultra 28L belongs to a higher-capacity continuous flow class and may be capable of supporting two showers operating simultaneously, depending on their flow requirements.
However, this should not be treated as a guaranteed performance outcome without confirming the appliance's manufacturer-rated output at the relevant temperature rise.
Two high-flow showers can require substantially more hot water than two water-efficient showers.
The incoming water temperature also affects how much heating the appliance must provide.
Where simultaneous shower use is a priority, the combined fixture demand should be calculated before selecting the unit.
Can the Rheem Ultra 28L Supply Three Showers?
Three simultaneous showers can create significant hot water demand.
The Rheem Ultra 28L's higher nominal capacity may make it worth considering, but suitability depends on the flow rate of each shower, the required temperature rise and the manufacturer's verified performance data.
It should not be assumed that a 28L nominal capacity guarantees three showers at full flow.
For homes where three showers are regularly used together, a detailed hot water sizing assessment is recommended.
HOT WATER PERFORMANCE
Rheem Ultra 28L Flow Rate Explained
The Rheem Ultra 28L is identified as a 28L continuous flow capacity class.
Continuous flow water heater capacities are commonly expressed in litres per minute at a specified temperature rise.
The exact rating condition for this model should be verified from Rheem's technical documentation.
It is important not to assume that a nominal 28L rating means the unit will deliver 28 litres per minute at every required outlet temperature and in all seasons.
When colder water enters the appliance, more heating energy is required to reach the selected outlet temperature.
For accurate sizing, the manufacturer-rated output should be compared with the combined demand of the household's fixtures.
How Temperature Rise Affects Rheem Ultra 28L Performance
Temperature rise is the difference between the incoming water temperature and the required heated water temperature.
For example, water entering at 20°C and heated to 50°C requires a 30°C temperature rise.
If the incoming water temperature drops to 15°C, heating the water to 50°C requires a 35°C rise.
As the required temperature rise increases, the maximum heated water flow may decrease.
This is why the manufacturer's flow rating should always be considered alongside its specified temperature-rise condition.
For larger homes, this can make a meaningful difference when several showers or taps are used at once.
50°C PRESET CONFIGURATION
What Does 50°C Preset Mean on the Rheem Ultra 28L?
The 50°C preset designation identifies a version configured for a nominal 50°C outlet temperature.
This is an important product selection detail because hot water systems can be supplied in different temperature configurations.
A preset outlet temperature can provide a practical arrangement for suitable domestic applications, but it should not be confused with a guarantee of exactly 50°C at every fixture under all operating conditions.
Actual delivered temperatures can be affected by system operation, plumbing conditions and any additional temperature control or limiting arrangements.
The exact Rheem Ultra 28L 50°C preset operating characteristics should be confirmed from the manufacturer.
Rheem Ultra 28L 50°C Preset vs Other Temperature Configurations
Choosing the correct temperature configuration is important when replacing or installing a gas continuous flow hot water system.
A 50°C preset appliance is intended for a particular hot water delivery arrangement.
Other temperature configurations may be required where the property's plumbing design or intended application calls for a different supply temperature.
The appropriate configuration should be selected according to Rheem's installation instructions and applicable plumbing requirements.
Do not assume that the 50°C preset model can be freely adjusted to higher temperatures or that it is interchangeable with every other Rheem Ultra model.
Does a 50°C Preset Hot Water System Improve Safety?
Limiting hot water temperature is an important consideration for reducing scalding risk.
A 50°C preset appliance may help support an appropriate domestic hot water temperature arrangement when correctly installed.
However, a preset temperature alone does not remove the need to comply with applicable hot water delivery requirements.
Different fixtures and building applications may have different temperature requirements.
Any required temperature limiting arrangements must be determined for the specific installation.
JR Gas & Water assesses the installation configuration to help ensure the selected system is appropriate for the property's hot water requirements.
Does the Rheem Ultra 28L Provide Continuous Hot Water?
The Rheem Ultra 28L is designed to heat water continuously while demand remains within the appliance's operating capacity.
Unlike a conventional storage cylinder, it does not depend on a fixed volume of preheated water.
This can be useful for larger families where several people shower one after another.
However, continuous flow does not mean unlimited hot water output.
If the combined demand exceeds the heater's available capacity, outlet flow or temperature performance may be affected.
Correct sizing remains essential, particularly for homes with multiple bathrooms.

Rheem Ultra 28L Running Costs and Energy Efficiency
The Rheem Ultra 28L heats water on demand, avoiding the conventional storage heat losses associated with maintaining a large cylinder of hot water.
However, actual running costs depend on household water consumption, the appliance's energy efficiency, gas prices, incoming water temperature and the amount of heating required.
A higher-capacity continuous flow system does not automatically use more gas for the same amount of heated water simply because its nominal flow rating is larger.
Likewise, it should not be assumed that the Rheem Ultra 28L will always cost less to run than every storage system.
Accurate comparisons require verified manufacturer efficiency information and a realistic estimate of household usage.
Rheem Ultra 28L vs Smaller Gas Continuous Flow Systems
The Rheem Ultra 28L belongs to a higher nominal capacity class than many commonly installed domestic gas continuous flow heaters.

These are general capacity classes, not verified performance comparisons between specific appliances. Manufacturer ratings should be compared at equivalent temperature-rise conditions.
Rheem Ultra 28L vs 26L Continuous Flow
A 28L nominal capacity is approximately 7.7% greater than a 26L nominal capacity.
That difference may be useful in some higher-demand applications, but the practical benefit depends on the specific appliances and their rated temperature-rise conditions.
The larger nominal number does not automatically guarantee better shower performance in every home.
Gas supply requirements, installation suitability and actual household demand should be considered before selecting between capacity classes.
Rheem Ultra 28L vs 20L Continuous Flow
The Rheem Ultra 28L's nominal capacity class is 40% greater than a 20L class.
For households with substantial simultaneous demand, the additional nominal capacity may be worth considering.
However, a higher-capacity appliance may have different gas supply and installation requirements.
Homes with modest demand may not benefit from selecting a larger appliance solely because it has a higher litre rating.
Rheem Ultra 28L vs Gas Storage Hot Water
| Feature | Rheem Ultra 28L | Gas Storage |
|---|---|---|
| Heating Method | On-demand continuous flow | Heats and stores water |
| Storage Cylinder | No conventional integral storage tank | Yes |
