Hot Water Systems Gold Coast: Compare Electric, Gas, Instant Gas and Heat Pump Options

Feb 27, 2024

Choosing the right hot water system on the Gold Coast depends on your household size, energy source, space, access, water pressure and whether you want a simple replacement or a more efficient upgrade.

Gold Coast homes can suit several hot water system types, including electric storage, gas storage, instant gas, instant electric and heat pump hot water. The right choice is not always the cheapest product upfront. It should suit the property, the household’s hot water demand and the installation requirements.

Installed Today helps customers compare hot water systems online, including electric hot water systems, gas hot water systems, instant gas hot water systems, instant electric hot water systems and heat pump hot water systems.

Supply-only ordering is available across major Australian metro areas. Selected supplied-and-installed options are available on eligible products in Brisbane and Gold Coast service areas where shown.

Quick Answer

For Gold Coast homes:

  • Electric storage can suit simple like-for-like replacements and homes without gas

  • Gas storage can suit homes with existing natural gas or LPG

  • Instant gas can suit homes wanting continuous flow hot water where gas pipe sizing and water pressure are suitable

  • Instant electric is usually best for point-of-use applications, not whole-home demand

  • Heat pump hot water can suit homes wanting an efficient electric storage-style option with outdoor space, airflow and drainage

  • Solar hot water can suit homes with suitable roof orientation, minimal shading and practical installation access, but heat pump hot water may be a simpler alternative where the roof is shaded or difficult

If you are replacing an old system, do not automatically choose the same type or size. The better choice depends on household demand, bathrooms, shower habits, access, gas type, water pressure, electrical supply and whether the existing system was keeping up.

Best Hot Water System Types for Gold Coast Homes

Gold Coast homes vary from apartments and townhouses through to family homes, duplexes, acreage-style properties and coastal homes with limited side access. That means there is no single best hot water system for every property.

The main options are:

  • Electric storage hot water

  • Gas storage hot water

  • Instant gas hot water

  • Instant electric hot water

  • Heat pump hot water

  • Solar hot water

Each has different strengths, limitations and installation requirements.

Electric Hot Water Systems Gold Coast

Electric hot water systems are common in Gold Coast homes because they are familiar, widely used and suitable for properties without gas.

Electric storage systems heat water in a tank using an electric element. They can be a practical option for like-for-like replacement when the existing location, electrical supply, drainage and pipework are suitable.

Electric hot water may suit:

  • Homes without natural gas or LPG

  • Simple storage tank replacements

  • Customers wanting a familiar system type

  • Properties with suitable electrical supply

  • Outdoor or indoor locations where the selected model is suitable

  • Households with predictable hot water use

Common sizes include 250L electric hot water systems, 315L electric hot water systems and 400L electric hot water systems.

Do not automatically replace the old unit with the same size if it regularly ran out of hot water. A home with more people, longer showers, added bathrooms or changed usage may need a different size.

Popular electric storage options include the Rheem 250L Electric Hot Water System, Rinnai 250L Electric Hot Water System, Dux 250L Electric Hot Water System, Vulcan 315L Electric Hot Water System and Vulcan 400L Electric Hot Water System.

Gas Hot Water Systems Gold Coast

Gas hot water systems can suit Gold Coast homes with an existing natural gas or LPG connection.

Gas hot water systems are generally split into:

  • Gas storage hot water

  • Instant gas hot water

Natural gas and LPG are not interchangeable. A natural gas hot water system must be connected to natural gas, while an LPG unit must be connected to LPG. Gas work must be completed by a licensed gas fitter.

Gas Storage Hot Water Systems

Gas storage systems heat and store water in a tank. They can suit homes that already have a similar gas storage unit and want a familiar replacement.

Gas storage may suit:

  • Existing gas storage replacements

  • Homes with natural gas or LPG

  • Customers wanting stored hot water

  • Properties with a suitable tank location

  • Homes where the existing gas setup is compliant

Customers can compare 130/135L gas hot water systems and 160/170L gas hot water systems, depending on household usage.

Product options include the Rheem 4-Star 135L Natural Gas Hot Water System, Rheem 4-Star 135L LPG Gas Hot Water System, Vulcan 4-Star 135L Natural Gas Hot Water System, Vulcan 4-Star 135L LPG Gas Hot Water System and Vulcan 4-Star 170L Natural Gas Hot Water System.

Instant Gas Hot Water Systems Gold Coast

Instant gas hot water systems, also called continuous flow gas hot water, heat water when a hot tap is turned on. They do not store hot water in a tank.

Instant gas may suit:

  • Homes with existing natural gas or LPG

  • Households wanting continuous flow hot water

  • Properties with suitable gas pipe sizing

  • Homes with suitable water pressure

  • Outdoor wall-mounted installation

  • Customers wanting to save ground space

  • Like-for-like replacement of an existing instant gas unit

Common sizes include 16L, 20L and 26L systems. Larger homes often compare 26L instant gas hot water systems, but bigger is not automatically better.

For 26L systems, gas pipe sizing must be checked and water pressure must be suitable. Multiple showers or fixtures can still exceed the system’s capacity if demand is too high at the same time.

Popular instant gas options include the Rinnai Infinity B26 Natural Gas Hot Water System, Rinnai Infinity B26 LPG Gas Hot Water System, Rheem 26L Natural Gas Hot Water System, Rheem 26L LPG Gas Hot Water System, Rheem 20L Natural Gas Hot Water System and Rinnai Infinity B16 Natural Gas Hot Water System.

External gas units are designed for outdoor installation unless the model is specifically approved for internal flued installation.

Heat Pump Hot Water Systems Gold Coast

Heat pump hot water systems can be a strong option for Gold Coast homes where outdoor space, airflow, drainage and electrical suitability are available.

A heat pump uses electricity to move heat from the surrounding air into water stored in a tank. It can be a practical upgrade from older electric storage and may suit homes wanting an efficient electric hot water option.

Heat pump hot water may suit:

  • Homes replacing older electric storage systems

  • Properties without gas

  • Customers wanting to reduce reliance on gas

  • Homes with suitable outdoor space

  • Locations with clear airflow

  • Properties where condensate drainage can be managed

  • Households with solar PV where timer operation and usage suit

  • Homes where noise placement is suitable

Heat pumps are not automatically the best choice for every home. They need outdoor location planning, airflow clearance, drainage, access, electrical suitability and suitable noise placement.

Gold Coast homes close to bedrooms, side fences or neighbouring properties should consider operating noise when choosing the location.

Customers can compare medium heat pump hot water systems from 200L to 280L, large heat pump hot water systems over 280L and Wi-Fi enabled heat pump hot water systems.

Popular heat pump options include the iStore 270L Heat Pump Hot Water System, Rinnai Enviroflo V2 250L Heat Pump Hot Water System, Rinnai Enviroflo GR-Series 280L Heat Pump Hot Water System, Rinnai Enviroflo GR-Series 300L Heat Pump Hot Water System and Enviroheat 250L Heat Pump Hot Water System.

Instant Electric Hot Water Systems Gold Coast

Instant electric hot water systems heat water as it passes through the unit, but they are usually best for point-of-use applications rather than whole-home hot water.

Instant electric may suit:

  • Small sinks

  • Kitchenettes

  • Offices

  • Workshops

  • Low-demand fixtures

  • Compact point-of-use areas

Instant electric is not automatically suitable for an entire Gold Coast home. Some units may require high electrical capacity, dedicated circuits or three-phase power depending on the model and application.

Electrical suitability should be checked before ordering.

Solar Hot Water on the Gold Coast

Gold Coast homes can be suitable for solar hot water where the roof has strong sun exposure, minimal shading and safe access.

Solar hot water may suit homes with:

  • Suitable roof orientation

  • Suitable roof pitch

  • Minimal shading

  • Suitable roof structure

  • Safe roof access

  • Maintenance access

  • Adequate space for collectors

  • A suitable tank and booster setup

Most solar hot water systems need electric or gas boosting for cloudy weather, high-demand periods or cooler conditions.

Solar hot water is not always the best option where the roof is shaded, complex, fragile or difficult to access. In those cases, a heat pump hot water system may be a more practical efficient alternative.

STCs, rebates and incentives can change, so they should be checked before choosing a system based on rebate potential.

Choosing the Right Hot Water System for a Gold Coast Home

The right hot water system depends on the home and the people using it.

Key factors include:

  • Number of people in the home

  • Number of bathrooms

  • Shower length and frequency

  • Bath use

  • Kitchen and laundry use

  • Whether showers run at the same time

  • Existing system type

  • Whether the old system ran out of hot water

  • Natural gas or LPG availability

  • Electrical supply

  • Water pressure

  • Gas pipe sizing

  • Outdoor space

  • Drainage

  • Side access

  • Noise placement

  • Roof suitability for solar

  • Whether the product is supply-only or supplied-and-installed

For many Gold Coast homes, the best replacement is not simply the same model that was already installed. If your household has changed, the system size and type should be reviewed before ordering.

Hot Water Replacement vs Repair

If your current hot water system is not working properly, a licensed plumber, gas fitter or electrician may need to diagnose whether repair or replacement is the better option.

Repair may make sense if:

  • The system is relatively new

  • The tank is not leaking

  • The fault is minor

  • Parts are available

  • The system still suits the household

  • The issue is limited to a valve, thermostat, element or serviceable part

Replacement may be better if:

  • The storage tank is leaking

  • The system is old

  • Repairs are frequent

  • Parts are hard to source

  • The system no longer keeps up with demand

  • The current system type no longer suits the home

  • You want to upgrade to a different system type

Installed Today is positioned as an online supplier of hot water systems, water filters and pumps, with selected supplied-and-installed options on eligible hot water products in Brisbane and Gold Coast service areas where shown. Emergency plumbing, general repair diagnosis and ongoing servicing should be handled by licensed trades where required.

Gold Coast Installation Considerations

Hot water installation requirements can vary across Gold Coast properties.

Things that can affect installation include:

  • Narrow side access

  • Townhouse or unit access

  • Coastal exposure

  • Outdoor location

  • Existing valves

  • Pipework condition

  • Electrical circuit suitability

  • Gas type and gas pipe sizing

  • Water pressure

  • Drainage

  • Old unit removal

  • Base or slab condition

  • Compliance upgrades

  • Heat pump airflow clearance

  • Solar roof access and shading

A simple like-for-like replacement is usually different to changing system type or relocating the unit.

For supply-only orders, confirm the model, size, gas type, electrical requirements and installation suitability with a licensed installer before purchasing.

Rebates, STCs and Incentives

Some heat pump and solar hot water systems may be eligible for STCs, rebates or incentives depending on the product, location, installation details and current program rules.

These programs can change. Eligibility should be checked before purchase and should not be treated as guaranteed.

Do not choose a hot water system based only on a possible rebate. The system must still suit the home, household demand, location, airflow, roof conditions, drainage, access and electrical setup.

Supply-Only vs Supplied-and-Installed on the Gold Coast

Installed Today offers supply-only ordering across major Australian metro areas. This can suit customers who already have a licensed installer organised and want to order the product online.

Selected supplied-and-installed options are available on eligible products in Brisbane and Gold Coast service areas. Availability depends on the product, address and installation requirements.

For supply-only products, the listed product price generally covers the product only.

It does not usually include:

  • Installation labour

  • Plumbing alterations

  • Electrical work

  • Gas work

  • New valves

  • Pipework changes

  • Gas pipe upgrades

  • Drainage changes

  • Tempering valve upgrades

  • Pressure limiting valve upgrades

  • Expansion control valves

  • Old unit removal

  • Disposal

  • Compliance upgrades

  • Concrete bases or slab work

  • Flue kits unless listed

  • Temperature controllers unless listed

  • Relocation of the system

  • Rebate administration

  • Site assessment

For heat pump systems, confirm outdoor location, airflow, drainage, electrical suitability and noise placement.

For gas systems, confirm the gas type, gas pipe sizing, water pressure and outdoor installation location.

For electric systems, confirm electrical supply, access, drainage and tank size.

Frequently Asked Questions

What is the best hot water system for Gold Coast homes?

The best system depends on the property. Electric storage can suit simple replacements, gas can suit homes with natural gas or LPG, instant gas can suit continuous flow demand, and heat pumps can suit homes wanting an efficient electric option with suitable outdoor space and airflow.

Are heat pump hot water systems good on the Gold Coast?

Heat pumps can suit many Gold Coast homes because the climate is generally favourable, but the location must have clear airflow, drainage, electrical suitability and suitable noise placement.

Is instant gas hot water good for Gold Coast homes?

Instant gas can be a good option where the home has natural gas or LPG, suitable gas pipe sizing, suitable water pressure and an outdoor wall-mounted location. Natural gas and LPG are not interchangeable.

What size hot water system do I need?

Size depends on the number of people, bathrooms, shower habits, bath use, laundry use and whether multiple fixtures run at once. The old system’s performance should also be considered.

Should I replace my old hot water system with the same type?

Not always. A like-for-like replacement can be simple, but if the old system ran out of hot water, had high running costs or no longer suits the home, it may be worth comparing other options.

Do Gold Coast hot water systems qualify for rebates?

Some heat pump and solar hot water systems may be eligible for STCs, rebates or incentives depending on current rules, product type and installation details. Eligibility can change and should be checked before purchase.

Does supply-only pricing include installation?

No. Supply-only pricing generally covers the product only. It does not usually include installation labour, plumbing work, gas work, electrical work, valves, pipework changes, drainage, old unit removal, disposal or compliance upgrades unless clearly listed.
