What Are the Best Hot Water Systems In Melbourne? [Full Comparison]

Comprehensive Plumbing Inspection Melbourne
Without doing a little homework you might end up with a lukewarm purchase that’s not just unreliable, but leaves you out of pocket to cover constant repair and maintenance bills.

Think all hot water systems are the same?

Think again.

Without doing a little homework you might end up with a lukewarm purchase that’s not just unreliable, but leaves you out of pocket to cover constant repair and maintenance bills. That’s why understanding the differences between boilers, and how to choose the best unit for your home, is key to making a great investment.

More than a reliable source of hot water, your boiler is complex and nuanced. While none of us want to cut down on our steamy baths or appliance usage, you probably want to cut back on water bills riddled with inefficiencies.
To help you get the most out of your home, while keeping your costs down, let’s take a closer look at what makes a boiler good, great, or grand so you can select the right option for your Melbourne home and family.

Is it worth upgrading my hot water heater?

In some cases, your heater will tell you when it’s time for a replacement – usually with refreshingly cold clarity. 

If you find yourself suddenly soaked in an ice-cold shower, you’ll want to consider hot water system repairs, or start looking for a new unit (and fast).

Whether your current tank has burned out or you’re considering replacing one before it has a chance to fail, it’s likely you’ll want the best option for your home. Replacing your system with a newer model can help you meet usage demands for hot water in a larger family. Newer models are also more efficient, and you’ll see the difference recouped in your utility bills over time. 

Older systems are also more difficult to maintain, and the costs here can start to mount. They can also become less reliable and fall out of compliance with current safety regulations. Here, an upgrade for your hot water system can also bring you peace of mind.

How to decide on the best hot water system for you

With so many different options available, your head might start to spin trying to decide on a new system for your home. However, there are several criteria you can use to narrow down the field. 

Here are a few of the top factors for your consideration. 

Energy source

Start by considering the utilities you have available to your home and currently in place. 

Do you have electric, gas, heat pump, or solar? 

For example, you might love the idea of a gas unit, but if you don’t have a gas line to the home, the added expense is likely not worth it. If reducing carbon emissions is important to you, a change over to solar collector panels and corresponding tanks may be worthwhile and rewarding in more than one way – as water usage is the second largest source of greenhouse gas emissions in Australian homes. 

Storage type

Almost all boilers use a storage tank to hold and heat the water used throughout your home. These tanks can take up a lot of space and may be inefficient to keep water warm, but they are compatible with most energy sources. 

In contrast, you might want to explore a continuous flow system. These are significantly smaller and usually only heat one tap at a time. They can also be more cost effective and energy efficient to operate given their size and heat-on-demand design.

Water usage

Especially when it comes to the storage tank variety, plumbers will start by asking you how many people live in your home. 

They use this to roughly determine your daily water usage and the right size tank for your needs. For example, a family of five will require approximately 250 litres of water daily, although that doesn’t include extras like laundry usage. 

Energy efficiency

All modern boilers are likely to be more efficient than their older counterparts. 

That said, gas hot water heaters (both storage tank and continuous types) tend to be the most efficient of the bunch. That’s because Minimum Energy Performance Standards (MEPS) in Australia are used to ensure efficiency tied to an option that relies on fossil fuels. 


Heaters aren’t a minor purchase, so you’ll want to make sure you choose a brand (and a plumber) that offers a robust warranty. 

Some manufacturers cover parts up to 10 years, and many installers will include a workmanship guarantee on their service.
