Choosing a Hot Water System For Your Newcastle Home

Jarrad Smith • September 20, 2023

Selecting the right hot water system for your new home can feel like a daunting task, and there's a wide range of options and sizes available on the market, making the decision even harder.

We all have different needs in terms of heating water, whether it’s for a large suburban home or maybe an apartment. You may even require a hot water system for a new commercial property. Whatever your specifications, it’s important to choose the hot water system that suits you.

What types of hot water systems are available?

There is an eclectic range of hot water systems on the market, all of which perform the same function in a variety of ways. To give you an idea, here are the most common on the market.

Electric hot water system

Perhaps the most conventional option available on the market, electric hot water systems are reliable and heat water quickly. They also come in a range of different sizes to suit your residential or commercial needs. Electric hot water systems can be fitted inside or outside your property and don’t require a flue, like gas hot water systems. Electric systems also come in two varieties, either as a storage system with a tank to store the hot water ready for use. Or, an instant system, which only heats the water you need. One factor to consider if having an electric hot water system fitted outside your property, particularly in the Newcastle area is corrosion from the coastline.

Gas hot water system

Gas hot water systems are efficient and one of the cheaper options to operate, as gas, is a low-cost fuel despite the increase in fuel prices. Gas hot water systems require either a flue or a vent to pump carbon monoxide fumes outside. While you can have these systems fitted inside it’s considered safer to have them outside as there are risks of carbon monoxide leaks, or ventilation systems getting obstructed. Therefore, it's important to have your gas hot water system serviced annually by a qualified plumber.

Solar hot water system

Solar hot water systems are an environmentally friendly way to heat water in your home and not only utilise the free energy readily available from the New South Wales sun but also reduce your household's greenhouse emissions. While the initial costs are often more expensive than other systems, a solar hot water system will save you significant amounts of money on hot water in the long run. The downside to these systems is that they require significant roof space, so if you live in an apartment complex, this system won’t be for you. Additionally, this system obviously relies on sunlight, so overcast days will affect the system's ability to function effectively.

Heat pump hot water system

Heat pump hot water systems run on electricity much like conventional electric systems, although they are more expensive, but do save you money on your hot water bills in the long run. They are typically fitted outdoors as they require plenty of space around them to draw in the air and heat your water. These systems aren’t as effective in colder climates and need to be installed in a place where they can be kept within the temperature range of 4°C - 32°C all year round.

Next steps

The best next step is to reach out to a professional plumber in the Newcastle or Lake Macquarie area to learn more on any of the systems listed, and to provide you with professional advice and a free quote.
