Choosing the right hot water system for your home is essential for energy efficiency, long-term savings, and reliable hot water on demand. At Aussie Home Services, we supply and install high-quality hot water systems to suit your household’s needs. Whether upgrading to a more energy-efficient model or replacing an outdated system, our licensed plumbers ensure a seamless installation process with expert advice and professional service.

From electric and gas hot water systems to instantaneous and under-sink models, we help you find the perfect system to improve efficiency, lower energy bills, and provide uninterrupted hot water.

Types of Hot Water Systems We Install

Electric Hot Water Systems

Electric hot water systems are reliable, cost-effective, and easy to install, making them popular for many households. They use an internal heating element to warm water stored in an insulated tank, ensuring a steady hot water supply when needed.

Benefits:

  • Suitable for homes without gas connections
  • Available in a wide range of sizes to suit different household needs
  • Can operate on off-peak electricity to reduce energy costs

Cons:

  • Generally slower to heat water compared to gas systems
  • Higher running costs compared to gas and instantaneous systems

Learn more about our electric hot water systems.

Gas Hot Water Systems

A gas hot water system is an efficient, environmentally friendly option that provides instant and reliable hot water. These systems heat water using a gas burner, making them faster and more cost-effective than electric models.

Benefits:

  • Heats water more quickly than electric systems
  • Lower running costs, especially if connected to natural gas
  • Works efficiently even in high-demand households

Cons:

  • Requires access to a gas connection
  • Higher initial installation cost compared to electric systems

Explore our gas hot water systems for more details.

Instantaneous Hot Water Systems

Also known as tankless or continuous flow systems, these units heat water only when needed, reducing energy waste and ensuring a constant supply of hot water without the need for a storage tank.

Benefits:

  • Provides unlimited hot water on demand
  • It is more energy-efficient as it doesn’t require heating a whole tank
  • Compact size, freeing up space in your home

Cons:

  • May struggle to provide hot water simultaneously to multiple taps
  • Requires proper gas or electricity supply to function efficiently

Find out more about instantaneous hot water systems.

Under-Sink Hot Water Systems

Under-sink hot water systems like Zip or Rheem models provide instant boiling or warm water at the kitchen sink. They are commonly used in offices, small households, and commercial spaces where immediate hot water is required for tea, coffee, or cooking.

Benefits:

  • Provides near-instant hot water for kitchen use
  • It saves energy compared to constantly heating a large tank
  • Compact and easy to install under kitchen sinks

Cons:

  • Limited capacity, making them unsuitable for full household use
  • It can be costly to run if used frequently

Common Hot Water System Issues (and How We Fix Them)

“My current hot water system isn’t big enough for my household.”

An undersized system can lead to cold showers and frustrating water shortages, particularly during peak usage. Our team will assess your household’s water usage and recommend a suitably sized system to ensure your family always has a consistent and reliable hot water supply. We offer solutions such as installing a larger storage tank, upgrading to an instantaneous system, or adding a booster to meet higher demand.

“My energy bills have increased, and I think my hot water system is why.”

Older systems lose efficiency over time, using more energy to heat water due to sediment buildup, aging heating elements, or insulation degradation. Our specialists will conduct a detailed energy efficiency assessment to determine whether repairs or a system replacement would be more cost-effective. We can also install energy-efficient alternatives, significantly reducing ongoing electricity or gas costs.

“The last plumber installed my hot water system, but it wasn’t done correctly.”

Improper installations can lead to inconsistent water temperatures, leaks, and early system failures. We begin by conducting a thorough inspection to diagnose any installation issues. Our licensed plumbers will correct any errors, replace faulty components, and ensure compliance with Australian plumbing standards, giving you peace of mind that your system will function efficiently and safely for years.

“I want to switch from an electric to a gas hot water system.”

Transitioning from an electric to a gas hot water system can reduce energy costs and improve heating efficiency, but it requires professional installation and compliance checks. We manage the entire process, including gas line installation, appliance connection, and system testing, ensuring your new system is installed to the highest safety and efficiency standards. 

“My hot water system is leaking, but I’m unsure if I need a repair or a replacement.”

Leaks may indicate a failing tank, faulty connections, or pressure issues. We begin with a system diagnostic, checking for visible and hidden leaks to determine the cause and severity of the problem. Minor leaks, such as a faulty valve or pipe connection, can often be repaired quickly and cost-effectively. However, if the tank is corroded or structurally compromised, we recommend replacing it with a durable, energy-efficient model with long-term reliability.

“My hot water drops off when someone else uses another shower, dishwasher, or washing machine.”

If your hot water fluctuates or runs out quickly when multiple taps or appliances are used, it could be due to an undersized hot water system or limited water flow capacity. We assess your home’s hot water demand and recommend upgrading to a more extensive storage system, installing a continuous flow unit, or improving your water pressure with a booster pump. This ensures consistent hot water throughout your household, even during peak usage.

I had a great experience with Aussie Services, especially with Luke, who came out to fix a blocked drain at my property. Luke was extremely professional, friendly and approachable. He took the time to explain the cause of the blockage, clearly explained what needed to be done, and resolved the issue efficiently. I really appreciated his knowledge, honesty and willingness to help. It's refreshing to deal with someone who genuinely takes pride in their work and provides excellent customer service. Highly recommend Luke and Aussie Services. I'll definitely use their services again in the future!

Very happy with the plumbing work done by Luke and his team. It was a big job but it was carried out with minimal disruption to the household, and the yard. Luke was always good in explaining how the job was progressing, and importantly when we had windows of opportunity to use the sewerage system during the day. They finished the job in a timely manner, and cleaned up afterwards. Happy to recommend this company.

Called and booked for Monday, given between 8 and 12pm for a possible gas leak. Chris showed up 1 minute after he called as he was just around the corner. Chris was polite, informative and professional. Checked all my appliances, one by one and the main meter. Lucky there was no leak and it was a billing issue. Better to be safe than sorry. Also as a first time customer received a discount which was nice as I saw on line if you mention it they knock it off the total price. Zero call out fee and all work quoted up front fixed price. Would highly recommend Aussie Home Services. Its hard yo find great trades these days and Chris fits the bill! Thank you.

We called out Aussie after hours on a long weekend on Grand Final night as we had no power. Not only did they answer, (a real person as well) they sent a level 2 electrician (Paul was highly skilled, extremely professional and a nice person to boot) out who fixed what was a serious issue, all I a few hours.. bravo all round

FAQ's

What’s the best hot water system for my home?

The best system depends on your household size, water usage, and energy preferences. Electric systems are typically cost-effective and easy to install, while gas systems offer faster heating and energy efficiency. Instantaneous systems are ideal for reducing energy waste, and under-sink units provide instant boiling water for convenience. Our team will assess your needs and recommend a reliable, long-term solution.

How long does a hot water system installation take?

Most installations take 2 to 4 hours, depending on the system type and whether additional plumbing work is required. If you’re switching from electric to gas, additional gas line installation may be needed, which could extend the process. Our licensed plumbers ensure a smooth and hassle-free installation so that you can enjoy hot water the same day

Should I choose an electric or gas hot water system?

Electric hot water systems are widely available and easy to install, making them an excellent option for homes without gas connections. However, gas systems are more cost-effective in the long run, as they heat water faster and consume less energy. A gas hot water system may be the best choice if you already have a gas connection.

Are instant hot water systems worth it?

Yes! Instantaneous hot water systems only heat water as needed, making them one of the most energy-efficient choices. They are ideal for smaller households or properties with limited space, eliminating the need for bulky storage tanks. These systems ensure an endless hot water supply while keeping running costs low.

Do you offer hot water system repairs?

We provide comprehensive hot water system repairs, including leak detection, thermostat replacements, element repairs, and complete system diagnostics. Whether your system is not producing hot water, experiencing fluctuating temperatures, or leaking, our team will assess and fix the problem efficiently.
