Electric Hot Water Systems: Prices, Replacement Costs & Buying Guide
Electric hot water systems are one of the most established options for heating and storing household hot water. Electric storage systems use an electric heating element to heat water inside an insulated tank, keeping it ready for showers, baths, kitchens, laundries and other household outlets.
Installed Today offers electric hot water systems for supply across major mainland Australian metro areas, with supplied and installed options available on selected systems in eligible Brisbane and Gold Coast locations. Compare capacity, cylinder construction, dimensions, element configuration, warranty and installation requirements before choosing your new system.
The current collection advertises electric hot water systems from $489. The live product grid above is the source of truth for current product pricing, stock and variants; this guide explains how that product price relates to supply-only, replacement and installed costs.
How Much Do Electric Hot Water Systems Cost?
Electric hot water pricing starts with the product itself, then changes according to whether you choose supply only, a standard replacement pathway or additional plumbing and electrical work. At the time of this September 2026 review, the current collection is advertised from $489.
Product cards above override this guide if pricing changes. Delivery is not automatically included unless the selected product or checkout says so.
What Does the Electric Hot Water System Price Include?
The advertised product or “from” price is the starting product price. It is not automatically the complete installed price, and it should not be read as including every valve, electrical change, removal, disposal, delivery or site-specific requirement unless those items are explicitly shown in the selected option.
Supply Only
Choose supply only when you already have appropriately licensed trades arranged. The product price covers the selected hot water system and product options only unless the listing says otherwise.
Like-for-Like Replacement
Replacing a compatible electric tank in the same position can be the simplest installed pathway where the existing plumbing, electrical supply, base, drainage and access remain suitable.
Extra Site Work
New circuits, tariff changes, switchboard work, relocation, valves, drainage, bases, difficult access, pipework changes and compliance upgrades can increase the completed cost.
How Much Does It Cost to Replace an Electric Hot Water System?
There is no single replacement price that applies to every property. The most useful starting point is the current product price above, then the installation pathway that matches the existing setup. A straightforward like-for-like job usually involves fewer variables than changing tank size, moving the system or changing the electrical arrangement.
Same Type, Same Position
Often the lowest-complexity replacement when the existing electric circuit, plumbing, drainage, base and installation position remain suitable.
Different Size or Configuration
Moving from 125L to 250L, 250L to 315L, single to twin element or to a tank with different connection positions can change plumbing, space and electrical requirements.
Relocation or Electrical Upgrade
A new location, new circuit, switchboard work, tariff changes or a long cable run can materially change the installed cost compared with a standard replacement.
Do not judge the cheapest replacement by the product card alone. A slightly dearer tank that closely matches the existing installation can sometimes be a simpler completed job than a cheaper product requiring more site work.
What Matters When Comparing Electric Hot Water Systems?
What Is an Electric Hot Water System?
An electric storage hot water system heats water using one or more electric elements inside a storage cylinder. Once heated, the water is held inside the insulated tank until it is required throughout the home.
Storage systems are available in a wide range of capacities, making them suitable for everything from compact applications and smaller households through to larger homes with higher stored hot water demand.
This differs from an instant electric hot water system , which heats water as it passes through the unit rather than storing a large volume ready for use.
How to Choose an Electric Hot Water System
Tank capacity is important, but it is not the only factor. Two electric hot water systems with a similar advertised capacity can differ in physical size, element configuration, tank construction, warranty and suitability for the existing installation.
Tank Capacity
Match stored hot water capacity to normal household demand rather than automatically choosing the largest available tank.
Household Demand
Consider occupants, bathrooms, shower duration, baths and whether several hot water outlets are regularly used close together.
Element Configuration
Check whether the existing system is single or twin element and whether the electrical setup suits the replacement model.
Cylinder Construction
Electric tanks are available in constructions including enamel-lined steel and stainless steel, depending on the model.
Dimensions & Access
Compare height, diameter, connection positions and the available path for removal of the old system and installation of the new one.
Installation Requirements
Plumbing, valves, electrical work, drainage, pipework and current compliance requirements can affect the final installation.
Electric Hot Water Installation Price Drivers
The product price is only one part of the completed replacement. These are the main items that can change the final installation cost.
| Price Driver | Why It Matters | Common Scenario |
|---|---|---|
| Tank capacity | Larger tanks usually cost more and can require more space and handling | Moving from 160L to 250L, 315L or 400L |
| Element configuration | Single and twin-element systems can have different electrical and tariff requirements | Replacing a twin-element tank with another compatible setup |
| Existing circuit | A suitable existing circuit can simplify replacement; a new or altered circuit adds electrical work | Old wiring, changed element load or relocation |
| Switchboard & tariff | Protection, timers and controlled-load arrangements may need checking or alteration | Old boards, tariff changes or circuit upgrades |
| Valves & drainage | Existing valves and discharge arrangements must suit the new compliant installation | Ageing valves, poor drain location or missing safe discharge |
| Base & access | The tank needs a suitable position and safe access for removal and installation | Indoor cupboards, stairs, tight side access or failed bases |
| Relocation | Moving the tank can add hot/cold pipework, drainage and electrical cabling | Moving outdoors, around a corner or to another service area |
Compare Electric Hot Water System Sizes
Electric storage systems are available in capacities from compact units through to large family tanks. The right size depends on household demand, heating schedule, element configuration and how the home uses hot water.
| Tank Size | Common Application | Why It May Be Chosen | Important Checks |
|---|---|---|---|
| 50L | Compact and low-demand applications | Small footprint where only limited stored hot water is needed | Recovery rate, expected demand and available space |
| 125L | Smaller households, units and lighter-demand properties | More stored capacity than compact systems without moving to a large family tank | Household demand and electrical setup |
| 160L | Small to medium households | Useful middle ground between compact and larger storage tanks | Usage pattern, available space and heating arrangement |
| 250L | Many standard family homes and replacement jobs | Popular balance of stored capacity, footprint and purchase cost | Peak hot water demand and heating schedule |
| 315L | Larger families and higher-use households | Additional stored water for homes with stronger daily demand | Space, access, electrical setup and actual household demand |
| 400L | Large or consistently high-demand households | High stored volume where smaller tanks may not provide enough capacity | Physical size, installation space and whether the extra capacity is genuinely required |
Size guidance is a comparison starting point. The electric selector above should be used alongside the specifications of the individual system and the requirements of the property.
Single Element and Twin Element Electric Hot Water
Single element electric hot water systems use one heating element and are common in residential replacement installations. Where the existing system is already single element, another compatible single element system may provide a straightforward replacement pathway.
Twin element electric hot water systems use two heating elements. Depending on the model, household demand and electrical arrangement, a twin element system can provide different recovery characteristics from a standard single element tank.
Element configuration should not be selected from tank size alone. Check the existing system, electrical circuit, tariff arrangement and manufacturer requirements before ordering.
Electric Hot Water and Off-Peak Electricity
Electric storage systems are commonly used with controlled-load or off-peak electricity arrangements where these are available at the property. The hot water system stores heated water so it remains available between heating periods.
The correct tank size becomes particularly important when heating is restricted to certain times. A system needs enough usable stored hot water to cover normal household demand until the next heating cycle.
Tariffs and heating times vary by electricity retailer, distributor and property configuration, so check the existing electrical setup rather than assuming a replacement tank will operate in exactly the same way.
What Does an Electric Hot Water System Cost to Own?
A lower purchase price does not automatically mean the lowest total cost. Compare the product price with installation complexity, electricity use, tariff arrangement, household demand, warranty, servicing and the likely life of the installation.
Product
Tank price, size, brand, cylinder construction and warranty.
Installation
Plumbing, electrical, valves, drainage, access, base and compliance work.
Electricity
Element load, household demand, tariff and heating schedule.
Ownership
Maintenance, serviceability, warranty support and future replacement compatibility.
Electric Storage vs Heat Pump for an Existing Electric Home
Staying with electric storage can be the most direct replacement pathway when the existing tank, circuit and installation location already suit the property. A heat pump can reduce hot-water electricity consumption, but it introduces different considerations including airflow, noise, condensate, clearances, electrical requirements and incentive eligibility.
If the priority is the simplest like-for-like replacement, start by comparing electric storage above. If the priority is lower hot-water energy use and the property suits the technology, compare the current heat pump hot water systems.
Electric Hot Water Systems Brisbane
Brisbane is a primary installation market for Installed Today. Selected electric hot water systems can be ordered with professional installation in eligible Brisbane, Logan, Ipswich, Moreton Bay and Redlands service areas, subject to the selected product, postcode and installation requirements.
Common Brisbane electric hot water jobs include failed tank replacements, leaking cylinders, upgrades from smaller systems, rental-property replacements and planned replacements of ageing electric storage units.
Where the existing electric tank has provided sufficient hot water, replacing it with a similar capacity and configuration is often the simplest starting point. Changing size, element configuration or installation position may require additional plumbing or electrical work.
Electric Hot Water Systems Gold Coast
Installed Today also offers selected electric hot water systems supplied and installed across eligible Gold Coast service areas.
Electric storage can be particularly practical where the property already has an electric tank and the priority is a straightforward replacement without changing the home's hot water energy source.
Installation suitability depends on the existing system, available access, tank dimensions, plumbing, valves, drainage, electrical supply and current installation requirements.
Buy Electric Hot Water Systems Across Major Australian Metro Areas
Customers who already have an appropriately licensed installer arranged can order electric hot water systems for supply across supported mainland Australian metro areas.
Our main electric hot water markets include Brisbane, Gold Coast, Sunshine Coast, Sydney, Melbourne, Perth and Adelaide, together with major regional and metropolitan centres including Townsville, Cairns, Toowoomba, Newcastle, Central Coast, Wollongong and Geelong.
Installation availability is separate from product supply. Brisbane and Gold Coast are the primary installed electric hot water markets, while customers in other supported areas can purchase supply only where delivery is available and arrange their own appropriately licensed installer.
Replacing an Existing Electric Hot Water System
A like-for-like electric replacement is often the simplest option when the existing system has provided enough hot water and the installation location still suits the household.
Before choosing the replacement, compare the old system with the new model rather than relying on tank litres alone.
- Existing brand, model and tank capacity
- Single or twin element configuration
- Tank height and diameter
- Indoor or outdoor installation location
- Access for removal and replacement
- Hot and cold connection positions
- Electrical supply and tariff arrangement
- Existing valves and tempering setup
- Drainage and discharge requirements
- Current household hot water demand
A change in tank size, location or configuration may involve additional plumbing, electrical, drainage or compliance work compared with a straightforward replacement.
Electric Hot Water Brands
The current Installed Today electric range includes systems from established hot water brands including Rheem, Rinnai, Dux, Vulcan and Aquamax.
Brand is only one part of the decision. Compare tank capacity, cylinder material, warranty, physical dimensions, element configuration, connection positions and suitability for the existing installation.
For many replacement jobs, a model that closely matches the existing tank dimensions and installation setup can be more practical than choosing solely by brand or advertised price.
Should You Stay With Electric Storage?
Electric Storage
A proven, straightforward option available in many tank sizes. Particularly useful when replacing an existing electric storage system and retaining the same energy source.
Heat Pump
Uses electricity together with heat from the surrounding air. Often compared with standard electric storage when reducing electricity consumption is a higher priority.
Gas Hot Water
Gas storage and continuous-flow systems can suit properties that already have an appropriate natural gas or LPG supply.
