Jarrad Smith • January 19, 2024

Is your hot water system starting to give you grief with cold showers, odd noises, or a sudden jump in your energy bills? When it’s time to replace your system, the choice you make can have a big impact on your day-to-day comfort and your back pocket.

Here at Ausco Plumbing, we get that picking the best hot water system can be confusing, especially when there’s a lot to think about. That’s why we’re breaking it all down into simple terms, so you can find the best fit for your home and your family. If you’re planning a hot water system replacement in Newcastle, read on - we’ll help you make the right choice without the headaches.

Why You Might Need a Hot Water Replacement Newcastle

Most of us don’t give our hot water systems much thought until something goes wrong. But once the issues start, they can be hard to ignore. If your hot water system Newcastle is showing its age, there are a few signs that it might be time to look at a replacement.

Old or Underperforming Systems

Most hot water systems last somewhere between 8 and 12 years. As the years tick by, you might notice your system taking longer to heat water or struggling to keep up when everyone’s trying to have a shower. Even if it still runs, older hot water systems are usually less efficient and can cost you more on your power bills.

High Energy Bills and Frequent Breakdowns

Have you spotted a rise in your gas or electricity bills lately? Or maybe your hot water keeps cutting out without warning or leaks every now and then? If you find yourself calling a plumber Newcastle NSW out too often, it’s a good sign your system is coming to the end of its life. Upgrading to a new, energy-efficient hot water system replacement could save you a lot of stress and extra costs over time.

What to Know Before Replacing Your System

Choosing a new hot water system isn’t something you do often, so it’s worth thinking a few things through before you jump in. Electric, gas, heat pump, and solar hot water systems are among many options available; it's crucial to think about which one will work best for your property.

Usage Needs and Budget

Start by looking at how much hot water your household actually uses. A couple in a unit won't need the same setup as a family full of teenagers who love long showers. Bigger households usually need larger tanks or continuous flow systems. Your budget matters too, not just for buying the hot water system, but for the running costs down the track.

Energy Source Availability

Before choosing a new hot water system, it’s important to look at what energy sources you already have at home. Gas and electric systems are common, while solar and heat pump options offer greater energy efficiency. The best choice will depend on your setup, energy use, and long-term savings goals.

What’s the Best for Your Home?

Electric Systems

Electric hot water systems are one of the most common choices across Newcastle and all over Australia. They are easy to set up and usually have a lower upfront price compared to gas systems.

Pros:

Easy to fit into most homes without much hassle
Lower upfront costs compared to other options
Simple to operate and look after

Cons:

Ongoing running costs can be high, with electricity prices in NSW climbing
Slower to heat water once the tank runs empty
You will lose hot water during a blackout

If you want something straightforward to install and not too pricey at the start, an electric hot water system is worth a look. Just be aware that the ongoing running costs can add up over time.

Gas Systems

Gas hot water systems are a great option for larger households or for anyone who goes through a lot of hot water every day.

Pros:

Running costs are usually cheaper than electric
Water heats up quicker and recovers faster after use
Keeps working even during a blackout, provided it does not rely on electricity to start
Never-ending hot water with a continuous flow setup

Cons:

Higher upfront costs to install
You will need an existing natural gas connection, or you will have to arrange for one

Gas systems are a solid choice if you are looking for long-term savings and your household uses a fair bit of hot water daily.

Heat Pump Systems

Heat pump hot water systems use heat from the surrounding air to warm your water, kind of like a reverse fridge. They're energy-efficient and work well even when the sun isn’t shining, making them an excellent alternative to traditional electric systems.

Pros:

Uses up to 60–70% less electricity than standard electric systems
Works in a wide range of weather conditions
Doesn’t need gas or solar panels to operate
Government rebates may apply

Cons:

Higher upfront cost than standard electric systems
Requires good airflow and outdoor space
Can be noisier than other systems

Heat pump systems are ideal for homeowners who want a more efficient, eco-conscious upgrade without needing solar panels.

Solar Systems

Solar hot water systems are a smart choice for households looking to save on energy bills and make use of the Aussie sun. These systems use roof-mounted solar panels to heat your water, often backed up by a gas or electric booster for cloudy days.

Pros:

Significantly lower long-term energy bills
Environmentally friendly with lower carbon emissions
Government rebates and incentives often available
Great return on investment over time

Cons:

Higher upfront cost to install
Needs good sun exposure and sufficient roof space
May still need a booster system during poor weather

Solar systems are a great option if you’re after long-term savings and have the roof space to support solar panels.
