Hot Water Systems from $499

Electric, Heat Pump, Gas Storage & Instant Gas Hot Water Systems

The best starting point is the energy source and system format already available at the property. Each hot water type has a different balance of purchase price, running energy, recovery, physical space and replacement complexity.

How to Choose a Hot Water System

Start with the property, not the brochure. Existing energy supply, household demand, available space and connection layout usually eliminate unsuitable options quickly. After that, compare the systems that genuinely fit the site.

What Size Hot Water System Do I Need?

Storage hot water is usually discussed in litres, while continuous-flow gas is usually compared by litres per minute. Neither number should be used by itself. Recovery rate, heating window and actual household demand can make two systems with similar headline capacity perform very differently.

For storage sizing, a practical starting guide is around 40L of hot water per person per day for light use, 50L for average use, 65L for high use and 80L for very heavy use. Long showers, baths, high-flow fixtures and multiple bathrooms can move a household well above the average.

Which Hot Water Systems Use the Least Energy?

Australian Government energy guidance identifies heat pump and solar hot water as high-efficiency options. Heat pumps use a refrigeration cycle to move ambient heat into the water and can use substantially less electricity than conventional electric resistance storage. Solar hot water uses direct solar heat with backup energy when required.

Conventional electric storage remains simple and widely available and can work particularly well when heating is timed around suitable electricity tariffs or rooftop solar PV. Gas systems may still be practical where a property already has a suitable gas supply and is replacing an existing gas appliance.

Should I Choose a Storage or Continuous-Flow Hot Water System?

Storage systems heat water and keep it ready in a tank. This includes electric storage, most heat pumps, gas storage and solar storage. Continuous-flow systems heat water as it is needed and are most commonly seen in residential gas hot water.

Compare Hot Water System Brands

Hot Water Outlet stocks established and specialist hot water brands across electric, gas and heat-pump technologies. Brand is useful for narrowing the range, but compare the exact model because tank material, element options, refrigerant, recovery, warranty and dimensions can differ significantly within one manufacturer.

Replacing a Hot Water System

When a hot water system fails, the fastest route is usually to identify exactly what is already installed before comparing alternatives. A like-for-like replacement can reduce changes, but upgrading technology or capacity may make sense when the existing system no longer suits the household.

What Should I Check Before Ordering a Hot Water System?

System capacity is only one part of compatibility. Check the pressure rating, required valves, hot and cold connection positions, inlet and outlet sizes, electrical supply, gas type where applicable, approved installation location and available space.

Storage water heaters use pressure and temperature relief protection and can require additional pressure, expansion and temperature-control valves depending on the system and installation. These parts need to match the exact water heater rather than simply being selected by thread size.

Storage Temperature & Safe Delivery

Australian Government guidance recommends storing hot water at 60°C in storage systems to help manage bacterial risk. The temperature stored in the cylinder and the temperature delivered to fixtures are separate issues. Plumbing systems can use suitable temperature-control devices where required to limit delivered water temperature.

Hot Water Systems for Solar-PV Homes

Hot water can be an effective way to use daytime rooftop-solar generation. Conventional electric storage can be scheduled to heat during the day where the electrical arrangement allows it, while many modern heat pumps include timers, WiFi or solar-friendly operating modes.

Eligible heat-pump and solar hot water systems may also create Small-scale Technology Certificates. State and territory incentives can have separate eligibility rules, so rebates should always be checked against the exact model, location and current scheme.

Product price only. Delivery, valves, fittings, pipework, installation, gas or electrical work, old-unit removal, disposal and compliance upgrades are separate unless expressly included with the selected product.

Buy Hot Water Systems Online with Delivery Across Australia

Hot Water Outlet supplies hot water systems to eligible Australian postcodes, with delivery options depending on stock, product size and destination. Selected metro areas may have faster delivery options on eligible stocked systems.

Because water heaters are bulky freight, check the delivery option on the exact product and postcode. Urgent replacement orders should also confirm that the selected model, fuel, capacity and connection requirements are correct before dispatch.

Hot Water System Warranty & Maintenance

Warranty structure depends on the technology and product. Electric and gas storage products may separate cylinder coverage from elements, burners, valves, parts and labour. Heat pumps may separately cover the tank, refrigeration system, compressor and electronics. Continuous-flow gas systems can have separate heat-exchanger warranty terms.

Keep the model and serial number and follow the manufacturer’s maintenance requirements for the exact system.

Buying a Hot Water System from Hot Water Outlet

Hot Water Outlet is a supply-focused hot water store. Choose the system first, check the exact delivery option, then add the compatible valves, pipework and accessories required for the job. Installation is not included in the listed system price unless clearly stated separately.

For replacements, keep photos of the unit, data plate, valves, connections and surrounding area before ordering.
