What Types of Rheem Hot Water Systems Are Available?
Compare Rheem Hot Water System Types
| Rheem System Type | How It Works | Common Starting Point | Main Things to Check |
|---|---|---|---|
| Electric Storage | Electric element heats water stored inside a tank | Replacing an existing electric storage system | Tank capacity, element setup, dimensions and electrical supply |
| Rheem Stellar Electric | Premium electric storage range | Customers comparing premium Rheem electric storage options | Capacity, dimensions, material, installation position and electrical setup |
| Rheem Heat Pump | Transfers heat from surrounding air into stored water | Replacing electric storage with a more efficient electric technology | Capacity, airflow, noise, drainage and electrical requirements |
| Gas Storage | Gas burner heats water stored inside a tank | Replacing existing natural gas or LPG storage | Gas type, capacity, recovery, gas supply and clearances |
| Instant Gas | Gas burner heats water as it passes through the appliance | Replacing continuous flow or upgrading a suitable gas property | Flow rate, gas type, simultaneous demand and gas pipe capacity |
Rheem Electric Hot Water Systems
Rheem electric storage systems are a common starting point when a home already uses a traditional electric storage tank and the customer wants to retain the same hot water technology.
Rheem electric systems are available across multiple capacities, from compact applications through to larger family-sized storage tanks. The correct size depends on household demand, heating arrangement and whether the existing system has historically provided enough hot water.
When replacing an existing Rheem electric tank, compare the old and new system's capacity, dimensions, element configuration, connection positions and installation requirements rather than relying on litres alone.
Rheem Stellar Electric Hot Water Systems
Rheem Stellar electric systems sit within the premium side of the Rheem electric-storage range and are commonly compared by customers wanting a higher-specification Rheem replacement.
The live Installed Today Rheem range currently includes Stellar electric systems across several common household capacities, including models suited to smaller homes through to larger family applications.
A Stellar system should still be chosen around household demand and the installation rather than brand tier alone. Check the tank dimensions, storage volume, element configuration, access and the existing electrical setup.
Rheem AmbiPower and AmbiHeat Heat Pump Systems
Rheem heat pumps use electricity to run a refrigeration cycle that transfers heat from surrounding air into stored water.
The current Rheem range on Installed Today includes AmbiPower and AmbiHeat options, giving customers alternatives to conventional electric resistance storage when improved hot water efficiency is a priority.
Heat pumps need more installation planning than a basic electric tank. Compare tank capacity, noise, airflow, clearances, condensate drainage, electrical connection, service access and the proposed installation location.
Rheem Gas Storage Hot Water Systems
Rheem gas storage systems heat water with gas and keep it stored inside a tank ready for household use.
They are particularly relevant where the home already uses gas storage and the existing system has provided suitable hot water performance. In those situations, another compatible Rheem gas-storage system may provide a straightforward replacement pathway.
Compare natural gas or LPG, tank capacity, recovery performance, dimensions, installation clearances, gas supply and existing connection positions before selecting the replacement.
Rheem Instant Gas Hot Water Systems
Rheem continuous-flow gas systems heat water as it is required rather than maintaining a large stored volume of hot water.
The current Installed Today Rheem range includes multiple residential continuous-flow sizes in both Natural Gas and LPG, allowing the system to be matched to household demand and the property's fuel supply.
Continuous-flow gas should be sized around simultaneous hot-water use, incoming water temperature, required temperature rise, available gas supply and gas pipe capacity.
How to Choose the Right Rheem Hot Water Size
Rheem systems are not all sized in the same way because each hot water technology behaves differently.
| Rheem Type | Main Sizing Measure | What Drives the Choice |
|---|---|---|
| Electric Storage | Tank capacity | Household demand, heating schedule and recovery |
| Heat Pump | Tank capacity + recovery | Household demand, operating schedule, climate and system performance |
| Gas Storage | Tank capacity + gas recovery | Peak demand and how quickly stored hot water is reheated |
| Continuous Flow Gas | Flow class | Bathrooms, simultaneous outlets, temperature rise and gas supply |
Replacing an Older Rheem Hot Water System
If the existing Rheem system has provided enough hot water and the property setup still suits the household, another comparable Rheem system is often the simplest place to start.
Check the existing system before choosing the replacement:
- Existing Rheem model
- Energy source
- Tank size or flow rate
- Natural gas or LPG
- Single or twin element where applicable
- Physical dimensions
- Connection locations
- Installation position
- Electrical requirements
- Gas supply requirements
- Household hot water demand
- Current compliance requirements
Changing from One Rheem Hot Water Type to Another
Staying with the Rheem brand does not mean different Rheem technologies are direct replacements for one another.
Changing from Rheem electric storage to a Rheem heat pump, from Rheem gas storage to Rheem continuous flow, or from gas to electricity can change the plumbing, electrical, gas, drainage and installation requirements.
Compare the benefits of the new technology against the extra conversion work rather than assuming a brand-to-brand change will be like-for-like.
Dimensions and Connections Matter on Rheem Replacements
Two Rheem systems with similar advertised capacity can have different dimensions, connection positions and installation requirements.
This matters most where the system is installed in a tight location, beside other services, inside a cupboard, on an existing base or where plumbing and electrical connections are difficult to alter.
Compare the product dimensions and connections before ordering rather than assuming the new Rheem will occupy exactly the same footprint as the old one.
Rheem Hot Water Warranty Considerations
Warranty periods vary between Rheem product types and models, so the warranty should be checked on the individual product rather than applying one warranty period to every Rheem system.
Different components within the same system can also have different warranty terms. Product registration, installation, servicing, operating conditions and other manufacturer requirements may also affect warranty eligibility.
Compare the complete warranty information for the specific Rheem model before purchase.

Rheem Hot Water System FAQs
Straight answers to the most common questions about Rheem electric, heat pump, instant gas and gas storage hot water systems.
What are the most popular Rheem hot water systems?
Popular Rheem choices depend on the type of hot water system you want. Our best-selling Rheem heat pump is the Rheem AmbiPower 280L, our best-selling premium electric option is the Rheem Stellar 250L, the Rheem 20L Natural Gas is a popular continuous-flow option, and the Rheem Stellar 330 is a popular premium gas-storage choice. The right system still depends on household demand, available energy source and the existing installation.
Which Rheem hot water system should I choose?
For a straightforward replacement of an existing electric storage system, compare Rheem electric models in a similar capacity. For lower electricity use, compare a Rheem heat pump such as the AmbiPower 280L. Homes already connected to natural gas can compare Rheem continuous-flow systems such as the 20L or 26L, while homes replacing an existing gas storage unit can compare options such as the Rheem Stellar 330. Household size, bathrooms, shower habits, available space and the existing electrical or gas setup should all be considered before ordering.
What Rheem heat pump is popular for a family home?
The Rheem AmbiPower 280L is one of our most popular Rheem heat pump choices for family homes. Rheem lists the 280L model as suitable for households of up to around six people under its stated sizing assumptions. It can be a strong upgrade from traditional electric storage where there is suitable outdoor space, airflow, drainage and electrical supply.
What is the Rheem Stellar 250L electric hot water system best suited for?
The Rheem Stellar 250L is a premium stainless-steel electric storage system commonly considered for small to medium family homes. It provides 250L of stored hot water, uses a stainless-steel cylinder and does not use a sacrificial anode. It is a good comparison option when you want a premium electric storage system rather than a standard enamel-lined cylinder.
Should I choose a Rheem 250L or 315L electric hot water system?
A Rheem 250L is generally the smaller of the two family-size options and can suit households with moderate stored-hot-water demand. A 315L system provides more stored water and is often considered for larger families, longer showers, bath use or homes with heavier morning and evening demand. The correct size also depends on tariff, element size, recovery time and how much hot water your household actually uses.
Is the Rheem 20L Natural Gas system suitable for a family home?
The Rheem 20L Natural Gas continuous-flow system delivers up to 20 litres per minute at a 25°C temperature rise and can suit many smaller to medium homes already connected to natural gas. It is commonly considered for homes with up to around two bathrooms where water pressure, gas supply and simultaneous hot-water demand are suitable. Larger or higher-demand homes may need to compare a higher-flow model such as a Rheem 26L.
Does the Rheem Stellar 330 have a 330L storage tank?
No. The Rheem Stellar 330 has approximately 130L of stored water. The “330” refers to its strong first-hour hot-water capacity rather than the physical storage volume. Rheem rates the system at approximately 330L first-hour capacity with fast gas recovery, making it very different from a 330L electric storage tank.
Can I replace an old Rheem electric system with a Rheem heat pump?
Often, yes. A Rheem heat pump can be considered when replacing an existing electric storage system, but it is not automatically a like-for-like installation. Heat pumps need suitable outdoor space, airflow, drainage and electrical connection. Changes to the electrical connection, pipework, base, drains or installation position may require additional work beyond a Basic Install.
Can I buy a Rheem hot water system supply only?
Yes. Supply only means you are purchasing the Rheem hot water system without an Installed Today installation package. It is intended for customers who already have the appropriate licensed installer arranged. Installation labour, valves, removal and disposal of the old system, electrical work, gas work, extra pipework and compliance upgrades are not included unless purchased separately.
Can I buy a Rheem hot water system supplied and installed?
Yes. Supplied and installed options are available for selected Rheem systems in eligible installation areas. The Basic Install is designed around a compliant external, ground-level replacement in the existing location. The product page installation checker should be completed before ordering because valves, electrical changes, gas upgrades, disposal, additional pipework, difficult access or relocation may require extra work.
What does a Rheem Basic Install include?
Basic Install pricing is designed for a standard external, ground-level replacement where the existing services and installation location are suitable for the selected system. The exact scope depends on whether the Rheem system is electric storage, heat pump, gas storage or continuous flow. Required valves, disposal, new circuits, gas upgrades, relocation, additional pipework and non-standard access are not automatically included unless shown in the selected package or purchased as an add-on.
What can change the installed price of a Rheem hot water system?
Installed pricing can change when the job needs more than the matching Basic Install. Common examples include replacement valves, old-system disposal, additional pipework, a new base, difficult access, electrical circuit work, changing electrical connection type, gas pipe or regulator upgrades, relocation, internal installation or other compliance work. The product page installation checker identifies the common items to review before checkout.
