Depending on where you live, what your availability to services and how much hot water you consume can greatly impact which type of system is best for you, electric or gas.

The most common types of hot water systems are electric, solar, heat pump and gas. Each having their own pros and cons, some being more affordable to purchase, where some are more affordable to operate. 

When you're deciding between a gas or electric hot water system, there are a few points you need to take into consideration. Keeping in mind, in Australia as of 2010 electric hot water systems are being phased out.

How many people are living in the property?

This is important as it will help to determine how much hot water is being used during the day.

Will a larger system be needed if more people are using hot water? and, what is the main use for the heated water?

A commercial property may be using boiling water for cooking and industrial cleaning and may be different from the use of a private residential property.

The space in your property

You will need adequate space available for your hot water cylinder or it will not work efficiently.

Any pipework will also need to be accessible and installed correctly to avoid burst pipes in the future.

This is dependent on the space where you are considering of having the system.

Remember some hot water heaters can be installed only outside and some only inside and some systems can be installed in both areas of your property.

A thorough inspection of your property by a local plumber will determine the best area for your gas or electric hot water system.

What heat source is available

You cannot have a gas hot water system if your energy source does not support gas.

If your home hasn't been set up to support gas, or you're in an area that doesn't allow the use of gas appliances, you may be restricted to another form of power like solar or electric.

What type of hot water service you are looking for

Storage tanks or continuous flow (instantaneous)? Keep in mind that instantaneous hot water systems only produce the heated water when needed and storage tanks or cylinders store the hot water for you.

Energy Efficiency

Choosing an energy-efficient system will benefit the environment as well as your pocket.

Gas is commonly considered the most energy-efficient hot water system and you can refer to the energy star rating.

That being said, gas does need to be connected to your home, and gas stored in a secured gas chamber.

Electric storage water heaters must meet minimum energy performance (MEPS) requirements under Australian laws.

Costs to run the hot water system

Water heating is the largest source of greenhouse gas emissions from an average Australian home. They also consume up to 21% of the average households energy consumption.

The ongoing running costs will be a consideration as well as the first initial install of the system. Hot water systems differ in the installation process as well as the ongoing running of the hot water system.

Your choice will depend on how much you are wanting to spend upfront and also the duration of using the hot water system for example maintenance and repairs costs should be a factor to consider.

Are there any rebates available?

In Australia, we are lucky enough to have a proactive government when it comes to providing rebates for energy-efficient choices. You can check the energy.gov.au website for updates on current rebates available.

How hot water systems work

So which is better? Gas or Electric Hot Water System?

All of the above points are important to think about when your choice between a gas or electric hot water system.

You are better off to call a licenced local plumber to clarify any questions you have as they are the most experienced in all types of hot water system installations and will help you in finding the right hot water system for you and your home, whether it be gas or electric.

Below is a brief outline of the difference between a gas and electric hot water system that you can choose from.

Gas Hot Water System

There are many benefits to having a gas hot water system.

It is quicker when it comes to heating and it is more environmentally friendly as the gas emissions are lower compared to electric hot water systems.

Most houses are choosing to have gas as an energy source in their homes due to high energy efficiency but due to ventilation, a gas hot water system would usually be installed outdoors.

There are three types of Gas hot water systems, Storage where water is heated and stored in an insulated tank and used when required, Instantaneous (continuous flow) where water is heated only when required and does not need a storage tank and Solar water heater with instantaneous gas boosting, where a solar hot water system uses gas as a back up the heat the hot water.

Electric Hot Water System

Most homes commonly run off electricity.

So having an electric hot water system would be the best option for them. Having an electric hot water system would be ideal for larger homes with more residents as they are able to hold and heat large quantities of hot water. An electric hot water system also has the benefit of being installed outdoors and indoors.

There are also two types of Electric hot water systems, Storage tank, Instantaneous. Both work differently and deciding on what kind of electrical hot water system you want depends on your home and the amount of water you will be using.
