What Makes a Smart Electric Hot Water System Different?
A smart electric hot water system still stores and heats water using an electric element, just like conventional electric storage. The difference is the control system. Wi-Fi connectivity and app-based management allow the homeowner to influence when and how the system heats rather than treating it as an appliance that operates entirely in the background.
| Feature | Standard Electric | Smart Electric |
|---|---|---|
| Stored Hot Water | Yes | Yes |
| Electric Element Heating | Yes | Yes |
| Wi-Fi Connectivity | Normally no | Built into compatible smart models |
| App Control | Normally no | Yes on compatible systems |
| Heating Schedules | Requires external control where applicable | Can be managed through the smart control system |
| Energy Visibility | Limited | Available on compatible smart systems |
| Solar PV Timing | Possible with suitable external control | Can be scheduled around daytime solar generation |
| Best For | Simple low-cost electric storage | Homeowners wanting greater control over electric storage |
Thermann Smart Electric Hot Water Systems
The Thermann Smart Electric range is the main smart electric storage direction offered by JR Gas & Water. It keeps the familiar format of an electric storage tank but adds built-in Wi-Fi and control through the Thermann Control app.
Through the app, compatible Thermann Smart Electric systems can provide heating schedules, operating modes, remote control and visibility over energy use and estimated power cost. This gives homeowners considerably more control than a traditional electric storage tank.
Thermann Smart Electric Sizes
80L Smart Electric
Compact smart electric storage for smaller homes and low hot water demand where app control is still desirable.
125L Smart Electric
Compact residential storage for smaller households wanting smart scheduling and Wi-Fi control.
160L Smart Electric
A useful step up in capacity for smaller households needing more stored hot water.
250L Smart Electric
Family-size smart storage that combines practical capacity with app-based heating control.
315L Smart Electric
Larger family storage for homes wanting greater hot water reserve while retaining smart scheduling.
400L Smart Electric
High-capacity smart electric storage for larger households with substantial daily hot water demand.
Smart Electric Hot Water Modes & App Control
Thermann Smart Electric systems provide four main operating modes through the Thermann Control app. The most suitable mode depends on whether the priority is convenience, predictable scheduling, reduced unnecessary heating or managing the system while the home is vacant.
Schedule Mode
Choose when the water heater operates so heating can be aligned with household routines, suitable electricity tariffs or available solar PV generation.
Eco Mode
Uses learned household usage patterns to adjust heating behaviour and reduce unnecessary heating where possible.
Holiday Mode
Allows the hot water system to be managed when the property is vacant rather than continuing normal operation unnecessarily.
Manual Mode
Provides more direct control of the system where the homeowner wants to manage the operating settings themselves.
Smart Electric Hot Water with Solar PV
Smart electric hot water can be a strong match for homes with rooftop solar PV. Instead of allowing the water heater to run at an inconvenient time, compatible smart scheduling can move more of the heating period into daylight hours when the home is producing solar electricity.
This effectively allows the storage tank to act as a thermal battery: electricity is used to heat water when power is more favourable, then the stored hot water is kept in the insulated tank for showers, kitchens and bathrooms later.
Smart Electric Hot Water & Electricity Tariffs
One of the main advantages of smart electric hot water is the ability to think about hot water heating as a controllable electrical load. Where an electricity plan has different prices at different times of day, heating can potentially be scheduled towards more favourable periods while still maintaining enough stored hot water for the household.
However, the electricity supply to the water heater needs to be considered. A smart hot water system cannot communicate or heat at a time when its power supply has been physically interrupted by an external controlled-load arrangement.
Smart Electric Hot Water & 3 Hour Free Power
A free or very low-cost daytime electricity window makes controllable hot water especially interesting because the tank can store heat for later use. Smart electric systems can help move heating into selected time periods, but the right solution depends on how much energy the system can put into the tank during the available window.
A standard smart electric system and a purpose-designed 3-hour free-power setup are not automatically the same thing. Element size, tank capacity, starting water temperature, household demand and the available heating window all affect how much water can actually be reheated during those three hours.
| Option | Main Strength | Best For |
|---|---|---|
| Smart Electric Storage | App control and flexible scheduling | Homes wanting everyday control over when the tank heats |
| 3-Hour Ready Electric Setup | Designed around maximising a defined free-power window | Homes specifically targeting free daytime electricity |
| Heat Pump | Lower electrical input for water heating | Homes prioritising overall energy efficiency |
Wi-Fi Requirements for Smart Electric Hot Water
Smart features depend on a reliable Wi-Fi connection reaching the hot water system. This can matter because hot water units are often positioned outside the home, down the side of the property or some distance from the household router.
Before Installation, Consider:
- Whether your home Wi-Fi reaches the hot water system location.
- Whether the system is within reliable 2.4 GHz Wi-Fi coverage.
- Whether a Wi-Fi extender may be useful at the installation position.
- Whether the water heater has continuous power available for smart functions.
- Who in the household needs app access and system control.
If Wi-Fi is temporarily unavailable, the Thermann Smart Electric can still operate as an electric storage water heater; however, the connected smart benefits depend on the system being able to communicate with the network.
How Much Does a Smart Electric Hot Water System Cost?
Smart electric hot water systems generally cost more than comparable standard electric storage because the system includes additional control hardware and connected features. The final installed cost also depends on tank size, element configuration and the work required at the property.
JR Gas & Water displays current smart electric systems and installed pricing in the product range above, allowing homeowners to compare the actual available systems rather than relying on a broad price estimate.
What Can Change the Installed Price?
- Smart electric tank size.
- Element size and electrical requirements.
- Condition of the existing plumbing and valves.
- Existing electrical supply and tariff configuration.
- Like-for-like replacement versus relocation.
- Drainage and relief valve requirements.
- System base and support requirements.
- Access and removal of the old hot water system.
What Size Smart Electric Hot Water System Do I Need?
Smart controls do not remove the need to size the storage tank correctly. The system still needs enough capacity and recovery to supply the household's normal hot water demand.
| Smart Electric Size | General Position | What to Consider |
|---|---|---|
| 80L | Compact / low demand | Daily usage and available reheating time |
| 125L | Smaller household | Shower habits and heating schedule |
| 160L | Small-to-medium household | Peak usage and recovery requirements |
| 250L | Family-size storage | Daily demand and tariff strategy |
| 315L | Larger family storage | Multiple bathrooms and heavier peak demand |
| 400L | High-capacity storage | Large households and genuinely high hot water usage |
Smart Electric vs Standard Electric Hot Water
Both systems use electric resistance heating and stored hot water. The main difference is control. Standard electric remains the simpler and lower-cost choice, while smart electric provides greater visibility and control over the heating cycle.
| Comparison | Smart Electric | Standard Electric |
|---|---|---|
| Upfront Cost | Higher | Lower |
| Heating Technology | Electric resistance element | Electric resistance element |
| App Control | Yes on compatible systems | Normally no |
| Scheduling | Built into the smart platform | May require separate external controls |
| Energy Visibility | Greater | Limited |
| Best For | Control, solar timing and modern energy management | Simple and lower-cost replacement |
Smart Electric vs Heat Pump Hot Water
Smart electric and heat pump hot water solve different problems. Smart electric improves the control of resistance electric storage. A heat pump changes the heating technology itself and normally requires much less electrical energy to produce the same amount of heat.
| Comparison | Smart Electric | Heat Pump |
|---|---|---|
| Heating Method | Electric resistance | Heat transfer / refrigeration cycle |
| Energy Efficiency | Improved control of when energy is used | Generally much lower electrical input for water heating |
| Noise | Virtually silent | Fan and compressor noise |
| Mechanical Complexity | Relatively simple | More complex |
| Location Requirements | Similar to electric storage | Airflow and noise require consideration |
| Best For | Homeowners wanting control while retaining electric storage | Homeowners prioritising lower overall energy use |

View hot water installation on the Gold Coast →What We Look For Before Recommending Smart Electric Hot Water
Smart electric is a useful technology, but only where the controls solve a real problem for the household. These are the practical points we consider before recommending the upgrade.
Will You Actually Use the Smart Features?
If the homeowner never plans to schedule, monitor or control the tank, the additional smart hardware may provide little practical value.
What Electricity Plan Is the Home On?
Smart scheduling becomes much more useful when different times of day have different electricity values or the home has surplus solar.
Does Wi-Fi Reach the Tank?
Hot water systems can sit well outside the strongest part of the home network, so connectivity should be considered before assuming the app experience will be seamless.
Is the Tank Properly Sized?
No scheduling feature can fix a cylinder that is fundamentally too small for the household's peak hot water demand.
Is Smart Electric Better Than a Heat Pump?
If energy efficiency is the main objective, a heat pump deserves to be compared. Smart electric is strongest where simplicity, silence and controllability are higher priorities.
Is the Goal Specifically Free-Power Heating?
If the objective is to maximise a short free-power window, element recovery and tank capacity need to be examined rather than relying on the word “smart”.
Smart Electric Hot Water System FAQs
What is a smart electric hot water system?
A smart electric hot water system is an electric storage water heater with additional connected controls. Compatible systems can provide features such as Wi-Fi connectivity, app control, heating schedules, energy-use visibility and different operating modes while still heating water with a conventional electric element.
What can the Thermann Smart Electric app control?
The Thermann Control app supports Manual, Eco, Holiday and Schedule operating modes. It can also provide visibility over energy use and power cost and allows compatible systems to be managed remotely while connected.
Can smart electric hot water use solar power?
Yes. A smart electric storage system can be scheduled to heat during suitable daylight periods when rooftop solar PV is generating. Actual grid savings depend on the household's solar generation, electricity plan, hot water demand and heating schedule.
Is smart electric cheaper to run than normal electric hot water?
The heating technology is still electric resistance, so the main opportunity comes from smarter control rather than a fundamentally more efficient way of creating heat. Savings can come from reducing unnecessary heating or moving heating into periods when electricity is cheaper or solar generation is available.
Does smart electric hot water need Wi-Fi?
Wi-Fi is required to use the connected smart features of the Thermann Smart Electric system. Thermann specifies a 2.4 GHz network. If reliable Wi-Fi does not reach the water heater location, a network extender may be required.
Will a Thermann Smart Electric still heat water without Wi-Fi?
Yes. The water heater can still operate as an electric storage system if the app is not connected. Wi-Fi connectivity is required to receive the benefits of remote smart control and connected features.
Can smart electric hot water work with off-peak electricity?
The electrical supply arrangement needs to be considered carefully. If an external controlled-load supply physically removes power from the water heater, the unit cannot use its connected controls during that interruption. The tariff and electrical setup should be reviewed before changing to smart electric.
Is smart electric good for 3 hour free power?
Smart scheduling can help concentrate heating into a selected period, but the result depends on element power, tank size and how much reheating is required. Homes specifically trying to maximise a short free-power window should also compare JR's dedicated 3 Hour Free Power hot water setups.
What sizes do Thermann Smart Electric systems come in?
The Thermann Smart Electric range includes 80L, 125L, 160L, 250L, 315L and 400L hot water delivery sizes, allowing smart electric storage to cover applications from compact homes through to larger family households.
Is smart electric better than a heat pump?
They solve different problems. Smart electric provides greater control over conventional electric resistance heating, while a heat pump changes the heating technology and normally uses substantially less electricity to produce hot water. Smart electric may suit households prioritising simplicity, silence and scheduling; heat pumps are stronger where overall energy efficiency is the priority.
Is smart electric worth the extra cost?
It can be worthwhile when the household will use scheduling, solar timing, energy visibility or remote control. If none of those features will be used, a conventional electric storage system may provide better value.
Do you install smart electric hot water in Brisbane and Gold Coast?
Yes. JR Gas & Water supplies and installs smart electric hot water systems throughout Greater Brisbane, the Gold Coast, Logan, Ipswich, Redlands, Moreton Bay and surrounding South East Queensland service areas.
