The ultimate guide to hot water systems
Plumbing Installations in Tweed Heads

There is no right or wrong answer to the question: which is the best hot water system for my home? The right system for you will depend on a range of factors including your needs, budget, and property type. At Plumb-Jet and Gas-Jet, we have experienced engineers who can install gas, electric, and solar-powered hot water systems in your home. Let’s take a look at the differences between these systems and how to choose the best system for your property.
 

Gas vs electric vs solar hot water systems

Most hot water systems in Australia run on either gas, electric, or solar power, with around 48% of hot water in Australia heated using natural gas (https://www.yourhome.gov.au/energy/hot-water-service). But today, many Australians are turning to alternative energy sources, including solar power, to power their water heating systems.
 
All three systems have their own advantages and disadvantages, and choosing your system will no doubt come down to three main points:
 

  • How much hot water will you need?
  • How big is your installation budget?
  • What running costs can you afford?

 
Generally speaking, between these three systems, customers will always have to make a trade-off between installation costs and running costs. Those systems which cost more to install usually boast lower running costs, while low installation fees can mean higher running costs in the long term.
 

Why choose gas hot water?

Gas hot water is often considered the ‘moderate’ option for hot water systems, offering lower running costs when compared to electric but cheaper installation fees compared to solar. The benefits of using gas to heat your water include:
 

  • A good trade-off between lower installation costs and low running costs
  • Consistent pricing throughout the day, which means no additional fees for peak use
  • Relatively energy efficient, with fewer greenhouse gas emissions compared to electric

 
If your home is already connected to mains gas, gas can be a great, cost-effective option for heating water.
 

Why choose electric hot water?

Electric hot water is often chosen because out of all three systems it involves the cheapest installation costs. However, electric hot water carries higher running costs than the other two systems, making it often less ideal in the long run. Benefits of installing an electric hot water system include:
 

  • Low installation costs and easy installation
  • Reliable
  • Heating off-peak can be more cost-effective
  • Can be installed either indoors or outdoors

 

Why choose solar hot water?

Solar hot water is the most advanced hot water heating system available, but as such this means relatively high set-up costs compared to both electric and gas water heating. However, the benefits of solar hot water systems are many, including:
 

  • Energy consumption can be reduced by up to 90%
  • Very eco-friendly
  • Low running costs, which can slowly cover the costs of installation
  • Certain government incentives can help cover installation costs

 
However, it’s worth bearing in mind that solar-powered hot water systems can be unreliable on overcast days when the sun isn’t providing as much energy, and of course for some people the costs of installation are just too prohibitive.
