How to choose a new hot water system

When selecting a new hot water heating system for your home it is important to choose a water heater that will not only provide enough hot water for the entire family when they need it, but also one that it will do so in an energy efficient way, ultimately saving you money long term.  

Choosing the right energy source can have the biggest impact on your savings.  Often your chosen form of energy will also help narrow down your water heating options, as the types of fuel that are available in your area will determine where to begin your search, however there are a few other things to take into account. 

Here are five key things to consider when choosing a hot water heating system:

Annual Running Costs

How much is it likely to cost to heat your water using your chosen form of energy per year? 

The Purchase, Installation And Maintenance Costs

What will it cost you upfront to purchase the system, have it installed and are there any ongoing maintenance requirements?

Energy Efficiency

To maximize your energy and cost savings, you need to find out how energy efficient a water heating system is.  Many websites have good information on the energy efficiency ratings and saving for various hot water heating systems, the Energy Efficiency and Conservation Authority or EECA is a good place to start.

The Life Span

It is a good idea to source some reliable information regarding the expected lifespan of your selected hot water heating systems.  Sometimes systems are less likely to stand the test of time and may require budgeting for full or part replacements in the near future. 

How Much Hot Water You Need

Getting the correct sized water heating system will ensure you do not run out of hot water, and also maximise efficiency.  Consider how many people live in your household now and how many there may be in the future, as a general guide one person on average will use around 50 litres of hot water per day.


Choosing a new or replacement hot water heating system is one of the most important decisions you will make when it comes to long term cost benefits within your home.  Water heating costs generally make up about a third of your electricity bill; this is a large chunk of money and it makes sense to put some substantial thought into this decision to provide maximum cost and energy efficiency for the future.
