PRODUCT OVERVIEW
What Is the Rheem 315L Electric Water Heater?
The Rheem 315L Electric Water Heater is a conventional electric storage hot water system with a nominal capacity of 315 litres.
Rather than heating water only when a tap is opened, the appliance heats water inside a storage cylinder and maintains a reserve for household use.
This makes it a practical option for homes that want stored hot water available for showers, kitchen use, laundry and other daily activities.
The supplied product description identifies the Rheem 315L as part of Rheem's standard electric storage range.
It highlights several features relevant to replacement installations, including a protective Ultranamel-coated cylinder, dual-handed fittings and a design intended to accommodate common electric storage replacement applications.
For households already using an electric storage system, selecting a compatible replacement may avoid some of the additional changes involved in switching to a different hot water technology.
However, the exact installation requirements must still be checked against the selected model and existing property services.

HOUSEHOLD SUITABILITY
Who Is the Rheem 315L Electric Water Heater Best Suited To?
The Rheem 315L may suit households with significant daily hot water requirements.
Its large storage capacity can be useful for family homes with multiple bathrooms, consecutive showers or substantial kitchen and laundry usage.
The supplied product description identifies suitability for around nine people under particular standard sizing assumptions.
This should not be interpreted as a guarantee that every nine-person household will have sufficient hot water.
Actual suitability depends on shower duration, water flow rates, the number of simultaneous users, stored water temperature and available reheating periods.
A household with six people taking long showers may use more hot water than a larger household with short showers and water-efficient fixtures.
JR Gas & Water can assess actual household demand before recommending the Rheem 315L or an alternative system.
How Many People Can the Rheem 315L Supply?
The supplied product description refers to a sizing guide of approximately nine people under standard assumptions.
However, hot water sizing should account for more than occupant numbers.
Number of people in the home
Average shower duration
Showerhead flow rates
Number of bathrooms
Consecutive shower demand
Bath usage
Kitchen hot water consumption
Laundry hot water demand
Incoming cold water temperature
Stored water temperature
Heating element configuration
Electricity tariff and heating availability
For larger households, the selected heating configuration and electricity tariff may be just as important as storage capacity.
Is the Rheem 315L Suitable for a Family of Four?
The Rheem 315L may provide generous storage capacity for a four-person household.
However, a smaller system may be sufficient where the household uses water-efficient fixtures and has moderate daily demand.
Choosing a larger cylinder than necessary can increase purchase costs and may increase standing heat losses.
The correct size depends on usage patterns, heating arrangements and the property's requirements.
Is the Rheem 315L Suitable for a Large Family?
The Rheem 315L is intended for applications requiring a substantial reserve of stored hot water.
It may be suitable for larger families, homes with multiple bathrooms or households where several people shower consecutively.
However, even a 315-litre system can run out of hot water during periods of very heavy demand.
Where the system operates on a restricted off-peak tariff, it may not reheat until the next available heating period.
JR Gas & Water can help determine whether the Rheem 315L provides an appropriate balance of storage capacity and reheating capability.
Can the Rheem 315L Handle Back-to-Back Showers?
The Rheem 315L provides a large nominal storage volume that may support consecutive showers.
However, the number of showers available depends on shower duration, flow rates, incoming cold water temperature and the amount of hot water already used.
Once the available stored reserve is depleted, the system must reheat before full hot water capacity is restored.
A suitable twin-element arrangement may provide different reheating options, but its actual performance depends on the selected model and electrical configuration.
How Much Hot Water Does the Rheem 315L Store?
The Rheem 315L has a nominal storage capacity of 315 litres.
This is the volume stored inside the cylinder, not necessarily the total amount of mixed shower-temperature water available.
Stored hot water is generally mixed with cold water before delivery to household fixtures.
The available mixed water volume depends on stored temperature, incoming cold water temperature and the required outlet temperature.

| Twin Element | Uses two heating elements in an approved configuration that may provide additional reheating flexibility depending on the selected model and wiring arrangement. |
A twin-element system should not automatically be assumed to operate both elements simultaneously or provide a particular recovery time.
The selected model, element ratings, wiring requirements and tariff arrangement must be confirmed before installation.
How Does the Rheem 315L Electric Water Heater Work?
The Rheem 315L uses electric resistance heating to heat water stored inside a cylinder.
A thermostat controls heating according to the appliance's operating settings.
When household fixtures draw hot water from the system, incoming cold water replaces the water used.
The heating element then reheats the stored water when electricity is available and the thermostat calls for heating.
The system provides a reserve of hot water rather than unlimited instantaneous heating.
How Quickly Does the Rheem 315L Reheat?
Recovery time depends on the selected model, heating element rating, starting water temperature and available electrical supply.
The supplied product information does not establish a manufacturer-verified recovery time for the exact Rheem 315L model.
As a general calculation, heating 315 litres of water through a 40°C temperature rise requires approximately 14.7kWh of thermal energy before accounting for losses.
The actual time required depends on the installed heating element configuration and operating conditions.
Where the appliance operates on a restricted electricity tariff, reheating may be delayed until the next available heating period.
ENERGY & RUNNING COSTS
Is the Rheem 315L Electric Water Heater Energy Efficient?
The Rheem 315L uses conventional electric resistance heating.
Electric storage heating is established technology, but actual electricity consumption depends on daily hot water demand, standing heat losses, water temperature and heating arrangements.
It should not automatically be described as more energy-efficient than heat pump or solar thermal hot water systems.
For homeowners prioritising lower electricity consumption, a suitable heat pump may be worth comparing.
For households wanting a conventional electric storage replacement, the Rheem 315L may still be a practical choice.
What Affects Rheem 315L Running Costs?

Many manufacturers specify routine maintenance throughout the life of the system. Following these recommendations helps maximise the lifespan of the unit, maintain safe operation and reduce the likelihood of unexpected breakdowns.
Homeowner Maintenance – Every 6 Months
Every six months, homeowners should carefully operate the Pressure & Temperature Relief (PTR) Valve and Expansion Control Valve (ECV) (where fitted).
This simple maintenance helps:
- Confirm the safety valves are operating correctly.
- Flush away mineral deposits that can cause the valves to seize.
- Prevent excessive pressure from building inside the tank.
- Extend the life of the safety valves.
Why is this important?
Over time, minerals naturally found in water can build up inside the valves. If they are never operated, they may become stuck or fail when they're needed most.
A seized PTR or ECV valve can lead to:
- Excessive pressure inside the tank.
- Continuous leaking from the valve.
- Reduced system efficiency.
- Premature component failure.
- Potential safety risks.
Important: Always follow your manufacturer's instructions when operating the valves, as hot water will discharge during testing. If you're unsure or unable to perform this maintenance safely, contact a licensed plumber.

Recommended 5-Year Major Service
Current Price: $449
Most electric storage hot water manufacturers recommend replacing several key components approximately every five years to maintain reliable operation and protect the storage tank.
Our comprehensive 5-Year Service includes:
- Replacement of the sacrificial anode.
- Replacement of the Pressure & Temperature Relief (PTR) Valve.
- Replacement of the Expansion Control Valve (ECV).
- Full inspection of the hot water system.
- Electrical safety and operational testing.
- Inspection of pipework, valves and fittings.
- Leak and corrosion inspection.
- System performance testing.
Why These Components Matter
Sacrificial Anode
The sacrificial anode protects the steel tank from internal corrosion.
Instead of the tank rusting, the anode slowly corrodes over time. Once it has been consumed, the tank itself begins to rust from the inside, often leading to leaks and complete tank failure.
Replacing the anode is one of the most effective ways to extend the life of a storage hot water system.
Pressure & Temperature Relief (PTR) Valve
The PTR valve is one of the most important safety devices on your hot water system.
It automatically releases water if pressure or temperature inside the tank becomes too high, protecting both the system and your home.
Over time, scale and mineral deposits can prevent the valve from operating correctly, making regular testing and replacement essential.
Expansion Control Valve (ECV)
The ECV manages pressure created as water expands during heating.
A correctly functioning ECV:
- Reduces stress on the storage tank.
- Protects plumbing components.
- Helps extend the life of the hot water system.
- Reduces unnecessary water discharge through the PTR valve.
If Your Hot Water System Isn't Working
Before arranging a service, there are a few simple checks you can perform:
- Ensure the power is switched on at the electrical switchboard.
- Check whether the hot water circuit breaker or safety switch (RCD) has tripped.
- Confirm the isolation switch near the hot water system is turned on.
- Check whether your electricity supplier has scheduled an off-peak interruption.
- Look for obvious water leaks around the system.
- Check whether water is continuously flowing from the PTR or ECV valve.
- Listen for unusual noises such as excessive boiling, rumbling or banging.
- Confirm the system has had sufficient time to reheat after heavy water usage.
If your system still isn't producing hot water, contact JR Gas & Water for professional diagnosis and repair.
General Signs Your System May Need Attention
Arrange a service if you notice:
- Water leaking from the tank.
- Constant dripping from relief valves.
- Rust-coloured or dirty hot water.
- Reduced hot water capacity.
- Water taking much longer to heat.
- Unusual noises during heating.
- Visible corrosion.
- Fluctuating water temperature.
- Repeated electrical trips.
Early repairs are often significantly less expensive than replacing a failed hot water system.
Protect Your Warranty & Maximise System Life
Regular maintenance not only helps keep your hot water system operating safely and efficiently—it can also assist in meeting manufacturer maintenance requirements.
Ignoring recommended servicing may result in:
- Premature tank corrosion.
- Seized or leaking safety valves.
- Reduced efficiency and higher running costs.
- Unexpected loss of hot water.
- Avoidable repair costs.
- Shortened system lifespan.
- Possible reduction or loss of manufacturer warranty, depending on the manufacturer's maintenance requirements.
A small investment in preventative maintenance can add years to the life of your hot water system and help avoid the inconvenience and expense of an unexpected replacement.
