Types of Hot Water Systems in Newcastle

What type of water heater should you buy if you live in Newcastle? 

This is like asking what should I have for dinner tonight? It’s very dependent on a few factors and of course the individual’s needs and wants. The outline below are the pros and cons of each type of water heater for those who live in the Newcastle area. 

Solar Hot Water Systems

These are the most efficient water heaters on the market, they use less non renewable energy than any other types of water heaters and will work rain hail or shine provided that they are installed correctly and are from a reputable manufacturer.

They are the most expensive to purchase and install, however, they will give you the largest payback over their lifespan than any other, and they are still receiving around $1000 government rebate, these are my number 1 choice of water heater provided you can afford the upfront supply and install cost.

Heat pumps are 2nd on my list of efficient water heaters next to solar, and are outstanding in many ways, the technology has been around a long time and they seem to be getting better every year. Heat pumps have  received a bad rap over the years, however, manufacturers have really stepped up their game and are producing quieter more efficient and aesthetically pleasing units.

Heat pumps also still receive around $800-$900 worth of government rebates and are the ideal addition to any house or business that has solar power installed. Different heat pumps have different features and settings that can be programmed on a user friendly display or even via app on your phone. Heat pumps are my recommended install for the greenhouse that generates its own power.

Gas Hot Water Systems

Gas hot water heaters provide plenty of hot water and fast that’s why most people love them. They offer a range of many different sizes and types including the traditional gas storage hot water system or the instant gas hot systems.

Whilst not the most efficient water heaters in the market, they are affordable to purchase and install and do what they are designed to do and do it well. They are perfect for the larger family and with establishments with several users.

Electric Hot Water Systems

These are the most common hot water systems and they do a great job, there is a large range to choose from as far as size and brands and will be the cheapest to purchase and install. Depending on  how much you pay for power and what times of the day you use this power will greatly affect the efficiency and cost to run these systems.

Electric hot water systems are a great addition to any house that has solar power already installed provided that you are running these systems in conjunction with you solar system and at the times of day when the energy is free or cheapest.

As you can see there are many options and many different types of heaters and possibilities, however you need to decide what hot water system will suit you and your families needs.

The main contributing factors when deciding what is best for you are as follows:


How much can I afford up front?

Fuel Source

 Do I have solar power? Do I have gas or both?


What size will suit my needs and showering habits?

How long should a hot water systems last in Newcastle?

This is a question that customers ask many times, “How long should my hot water system last?”. It’s a variable question. Some hot water heaters last over 40 years whilst others only 7 years. So, why such a difference in life spans?

There are some interesting contributing factors throughout the years that contribute to the lifespan of water heaters.

Manufacturing in Australia or the world has changed. Hot water systems in particular seem to have lost the longevity they used to have.

Whilst manufacturing and designs have changed to a degree, they seem to be made faster and with less quality components than that of the water heaters of years gone by.

The quality of your water will pay big contributing factor in the life span of your water heater. If you have hard water or water that is full of minerals, this will react with the metal tanks causing them to rust out at a faster rate than that of areas with softer water.

Always check the manufacturer’s recommendations for your area before installing a water heater as there are some makes and models that just aren’t suitable for certain areas and water qualities.

If you have a hot water installation in Newcastle, you are able to install most brands and makes. However, if you have hot water installation in Port Stephens you will need to ensure that the correct model and make is installed due to the high mineral content of of water there.

When you have a licensed plumber in Newcastle to install your new water heater, he must install a pressure limiting valve on the cold water feed to you water heater.

This valve reduces the pressure to 500 KPA ensuring that the system isn’t affected by excessive pressure. Manufacturing warranties will be void if a pressure limiting valve is not installed on your hot water system.

Hot water servicing and the intervals in which you service your water heater will play a large part in how long your system lasts. 

It’s recommended that you have your hot water repaired or serviced in Newcastle every five years. This should include the replacement of the sacrificial anodes as a must.

Location of water heater seems to play a big factor in how long the water heater will last.  For whatever reasons hot water tanks that are installed inside always seem to outlast the units that are installed outside.

On the other hand,  installing them inside will pose danger if there is a leak as it can cause serious property damage and flooding.

Now this could cause some controversy. We recommend to stick to reputable brands with longer warranties. The warranties will vary across manufacturers. 

We advise to purchase water heaters with no less than 10 years warranty.
