Who Is the Thermann Smart 80L Best For?
Smaller Households
Thermann currently guides the 80L Smart Electric toward approximately 2–3 people on continuous supply or around 2 people on off-peak, subject to actual shower length and household usage.
Homes Wanting Smart Scheduling
A practical option where you want electric storage but also want to control when the element heats instead of relying only on a conventional thermostat and tariff.
Solar-PV & Time-of-Use Homes
Schedule Mode can be used to align heating with periods when solar PV is available or electricity tariffs are more favourable.
Is the Thermann Smart Electric 80L Right for My Home?
A Good Choice If...
You want compact electric storage with app control, predictable heating schedules and household demand that fits the 80L category.
Consider Another Size If...
Your household regularly has several long showers close together, higher simultaneous demand or needs more stored reserve than an 80L delivery rating provides.
JR Should Check First If...
You are changing element size, moving from off-peak to continuous supply, installing indoors, have difficult drainage or are unsure which hard-water configuration suits the property.
How Does the Thermann Smart Electric 80L Work?
The Thermann Smart Electric operates fundamentally like a conventional electric storage water heater. Hot water is drawn from the top of the tank while cold replacement water enters through the lower section.
When the water around the electric element falls below its required temperature, the element heats the stored water. Heated water rises toward the top of the cylinder ready for the next draw-off.
The difference is the smart control layer. The Thermann Control App can influence when the heater is allowed to operate, the selected operating mode and the target tank-temperature strategy, helping owners better match heating periods to their household and electricity setup.
In simple terms: it remains an electric storage tank, but the Wi-Fi controller gives you more control over when and how the tank heats.
Thermann Control App & Smart Features
Energy & Cost Monitoring
Thermann states that the app can display energy use and power-cost information to help owners understand how the water heater is operating.
Remote On / Off
The heater can be remotely controlled for periods such as holidays or when the property will be vacant.
Heating Schedules
Schedule Mode lets users choose when heating occurs, including times that may align with solar PV generation or lower electricity tariffs.
Temperature Control
The Smart Electric range allows remote adjustment of tank temperature while retaining the system's anti-legionella control strategy.
Usage Learning
Eco Mode uses machine-learning analysis of usage patterns to personalise heating and reduce unnecessary heating periods.
2.4GHz Wi-Fi
Thermann specifies a 2.4GHz Wi-Fi network for app connectivity. The Smart Electric is not designed to connect directly to a 5GHz-only network.
Four Thermann Smart Operating Modes
Direct Control
Allows the tank-temperature setting to be managed manually while maintaining Thermann's anti-legionella cycle.
Usage Learning
Uses machine learning to analyse household usage patterns and minimise unnecessary heating.
Vacancy Control
Allows remote control when the house is vacant or occupants are away.
Timed Heating
Lets users schedule heating around household routines, solar availability or electricity tariffs.

What's Included With Thermann Smart 80L Installation?
Selected Installation Package
The JR package chosen in the live selector above defines the standard labour and installation materials applicable to that replacement pathway.
Commissioning
The water heater is filled, connected, tested and commissioned for the completed plumbing and electrical scope before handover.
Possible Additional Work
Electrical circuit upgrades, indoor drainage protection, base work, relocation, valve changes, difficult access or other non-standard requirements can alter the final scope.
How Much Does Thermann Smart Electric 80L Installation Cost?
Use JR's live product and installation selector above for current supplied-and-installed pricing. Keeping pricing live avoids conflicts when package pricing, promotions, installation requirements or booking options change.
A straightforward replacement where the existing electrical circuit, valves, drainage and base already suit the new system can have a very different scope from an installation requiring electrical upgrades, relocation or changes for an indoor installation.
The chosen element size can also affect the required electrical circuit, so the final product and installation configuration should be treated together.
Thermann Smart Electric 80L Installation Brisbane
JR Gas & Water supplies and installs the Thermann Smart Electric 80L across eligible Brisbane service areas for suitable electric-storage replacements and upgrades.
For Brisbane homes, the system can be particularly useful where the owner wants to coordinate electric hot-water heating with a household schedule, controlled tariff or rooftop-solar production rather than relying on a basic storage heater.
The existing circuit, installation position, valve arrangement, drainage and available Wi-Fi signal should all be checked before treating the installation as a simple like-for-like swap.
Thermann Smart Electric 80L Installation Gold Coast
JR Gas & Water also installs the Thermann Smart Electric 80L across eligible Gold Coast service areas.
For compact homes, units and smaller households, the 490mm diameter can help where installation space matters, but the full 925mm cylinder height plus valve, drainage and servicing access still needs to be considered.
Where water chemistry is a concern, Thermann's separate hard-water variants provide a more appropriate product-selection pathway than assuming the standard model is automatically intended for every water condition.
Can the Thermann Smart 80L Replace My Existing Electric System?
Replacing Another 80L Electric Tank
This can be a relatively direct pathway where dimensions, electrical circuit, plumbing, valves, base and drainage remain suitable.
Replacing a 50L System
The 80L Smart provides greater stored hot-water capacity but requires more physical room, so the available position and electrical setup should be checked.
Replacing a Larger Tank
Downsizing should be based on actual household demand. Smart scheduling cannot compensate for insufficient physical storage during a heavy draw-off period.
Adding Solar-PV Scheduling
The smart-control features can help shift element heating into periods when rooftop solar production is available, subject to the home's electrical and tariff arrangement.

Your electric storage hot water system is built to provide years of reliable hot water, but like any major household appliance, it requires regular maintenance to remain safe, efficient and covered under the manufacturer's warranty.
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.
JR 6-Month Hot Water Health Check
Recommended Service – $99
While homeowner maintenance is important, a professional inspection provides additional peace of mind and can identify issues long before they become expensive repairs.
Our JR 6-Month Hot Water Health Check includes:
- Inspection for water leaks and corrosion.
- Testing of the PTR valve.
- Testing of the ECV (where fitted).
- Checking electrical operation.
- Inspecting wiring and electrical connections.

- Confirming correct operation and water heating performance.
- Identifying any components showing signs of wear.
Service Price: $99
Regular inspections help detect small problems early, reducing the likelihood of unexpected breakdowns and helping maximise the life of your hot water system.
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.
