Choosing the Right Electric Hot Water System

Before ordering an electric hot water system, check the existing unit and compare the product specifications carefully. Electric hot water systems can vary by tank size, dimensions, pressure rating, electrical requirements, connection layout and recovery performance.

Check these details before buying:

Storage capacity in litres
Brand and model number of the existing system
Tank dimensions
Water pressure rating in kPa
Hot and cold water connection locations
Inlet and outlet connection sizes
Power requirements
Element size and electrical supply requirements
Indoor, outdoor or external suitability
Available space for the tank
Household hot water demand
Required valves and fittings
Delivery access for larger products
Spare part compatibility

If you are replacing an existing electric hot water system, matching the capacity, dimensions, connection positions and pressure rating is the safest way to reduce ordering mistakes.

Electric Storage Hot Water Systems

Electric storage hot water systems heat water inside a tank and store it ready for use. They are usually compared by capacity in litres, with smaller tanks often used for apartments, units or low-use areas, and larger tanks used for family homes or higher daily demand.

A smaller electric hot water system may suit:

Apartments
Units
Granny flats
Small homes
Office kitchens
Point-of-use hot water
Low-demand areas
Replacement of compact tanks

A larger electric hot water system may suit:

Family homes
Multiple bathrooms
Rental properties
Higher daily hot water use
Homes replacing older storage tanks
Trade and maintenance supply orders

The right size depends on the number of people using hot water, shower habits, bathrooms, appliance use, recovery time and available space.

Electric Hot Water Parts, Valves and Accessories

An electric hot water order may require more than the main tank. Valves, fittings, electrical components and connection parts can be needed to suit the system, manage pressure, control temperature and complete a replacement setup.

Common products used with electric hot water systems include:

Tempering valves
PTR valves
Pressure limiting valves
Expansion control valves
Isolation valves
Non-return valves
Hot water connection kits
Copper connections
Braided connections where suitable
Unions and adaptors
Drain cocks
Thermostats
Heating elements
Anodes
Maintenance accessories

Ordering compatible hot water parts with the system can help make sure the right products are ready when needed.

Electric Hot Water Compared With Heat Pump Hot Water

Electric storage and heat pump hot water systems both store heated water in a tank, but they heat the water differently. A standard electric storage system uses an electric element inside the tank. A heat pump system uses heat from the surrounding air to help warm the stored water.

Electric hot water systems may suit customers looking for a straightforward replacement option, a compact tank, a lower upfront product price point, or a system that closely matches an existing electric setup. Heat pump systems may suit customers comparing energy efficient storage hot water options where space, airflow and operating requirements are suitable.

The best choice depends on the property, budget, available space, household demand, electrical setup and product specifications.

Electric Hot Water System Questions

What size electric hot water system do I need?

The right size depends on the number of people in the home, daily hot water usage, number of bathrooms, shower habits, appliance use and how quickly the system needs to recover. Electric storage systems are usually compared by tank capacity in litres.

How does an electric hot water system work?

An electric hot water system uses an electric heating element to heat water inside a storage tank. Once heated, the water is stored in the tank ready for use at taps, showers and appliances.

Can I replace my old electric hot water system with the same size?

In many cases, replacing with a similar size can be practical, but you should still compare the dimensions, connection locations, kPa rating, power requirements and household demand before ordering. Older systems may not match current product layouts exactly.

What is the difference between a small and large electric hot water system?

Small electric hot water systems are generally used for lower demand areas, apartments, point-of-use applications or compact spaces. Larger electric hot water systems store more water and are usually selected for family homes or properties with higher daily hot water use.

Do electric hot water systems need a tempering valve?

Many storage hot water systems use a tempering valve to help deliver water at a safer outlet temperature. The correct valve requirement depends on the system, water temperature, property setup and applicable plumbing requirements.

What valves are used with electric hot water systems?

Common valves may include tempering valves, PTR valves, pressure limiting valves, expansion control valves, isolation valves and non-return valves. The correct parts depend on the system specifications and water pressure requirements.

What kPa rating should I check for an electric hot water system?

Check the kPa rating listed on the electric hot water system and any matching valves or fittings. Pressure ratings need to suit the system and connected components.

Can I buy electric hot water spare parts online?

Yes. Hot Water Outlet sells hot water spare parts, valves, fittings, connections and accessories for a wide range of electric hot water system needs, including thermostats, elements and anodes where available.

What should I check before ordering an electric hot water replacement?

Check the current brand, model, capacity, dimensions, kPa rating, connection positions, power requirements, installation location and whether any valves, fittings or accessories are also required.

Yes. Hot Water Outlet supplies electric hot water systems, parts and accessories across Australia, with delivery options depending on stock, product size and delivery location.

Is same day delivery available for electric hot water systems?

Electric Storage Hot Water System FAQs

Common questions about choosing, comparing and ordering electric storage hot water systems online with Hot Water Outlet. We sell supply-only electric storage hot water products and can help organise quotes from reputable installers where appropriate.

Can I buy an electric storage hot water system supply only?

Yes. Hot Water Outlet sells electric storage hot water systems as supply-only products. This means the listed product price is for the electric storage unit only and does not include installation, valves, old unit removal, disposal, electrical work, plumbing changes, access equipment or compliance upgrades unless those items are clearly listed separately.

What is an electric storage hot water system?

An electric storage hot water system heats water inside a tank using an electric element. The heated water is stored ready for showers, taps, laundry and everyday household use, making it a common option for homes that already have an electric hot water connection.

What size electric storage hot water system do I need?

The right size depends on household size, shower habits, bathroom count, tariff type and how much hot water is used during peak times. Smaller households may suit compact tanks, while larger homes often compare 250L, 315L or larger electric storage models. A licensed installer should confirm the best size for your property before installation.

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

In many homes, replacing like-for-like with another electric storage hot water system can be a practical option. Suitability still depends on the existing electrical supply, plumbing layout, tank location, available space, valves, access and current compliance requirements.

Do electric storage hot water systems need a dedicated circuit?

Most electric storage hot water systems require a suitable electrical connection, and many are connected to a dedicated hot water circuit. Requirements vary by model, element size and property setup, so a licensed electrician or installer should confirm circuit suitability, switchboard capacity and compliance requirements.

Can electric storage hot water run on off-peak power?

Some electric storage hot water systems may be suitable for off-peak or controlled load tariffs, depending on the tank size, household hot water use and electricity provider arrangements. If using off-peak power, the tank usually needs enough stored hot water to last between heating cycles.

Are electric storage hot water systems suitable for solar power?

Electric storage hot water systems can be used in homes with rooftop solar, and some households use timers or suitable controls to heat water during daylight hours. Suitability depends on the electrical setup, solar system, tariff, tank size and how the home uses hot water.

Are electric storage hot water systems suitable for indoor or outdoor use?

Some electric storage models are suitable for indoor installation, some are suitable for outdoor installation, and some may suit both depending on the manufacturer’s design. Always check the product specifications and confirm the required location, drainage, clearances and access with a licensed installer.

What is the difference between mains pressure and low pressure electric storage?

Mains pressure electric storage systems are designed to deliver hot water at mains-style pressure where the plumbing setup supports it. Low pressure or gravity-fed systems are different and should not be replaced with a mains pressure unit without checking the property’s pipework, fixtures and compliance requirements first.

How long does an electric storage hot water system take to reheat?

Reheat time depends on tank size, element rating, incoming water temperature, tariff type and how much hot water has been used. A larger tank may take longer to fully recover, while a correctly sized system should be selected to suit the household’s normal hot water demand.

Do I need new valves, pipework or fittings?

Some electric storage replacements may require new valves, pipework, fittings, tempering valves or other accessories depending on the existing setup and current compliance requirements. Hot Water Outlet sells hot water valves, pipework and fittings online, but your licensed installer should confirm exactly what is required for your property.

Does the product price include old system removal or disposal?

No. Product pricing on Hot Water Outlet is for the product only unless clearly stated otherwise. Old system removal, disposal, access equipment, electrical work, plumbing changes and compliance upgrades should be quoted separately by the installer or licensed tradesperson completing the work.

What should I compare before buying an electric storage hot water system?

Compare tank size, indoor or outdoor suitability, dimensions, element rating, warranty details, recovery performance, connection locations, valve requirements and whether the model suits your household’s hot water demand. You should also confirm access, electrical supply, plumbing layout and local installer availability before purchase.
