System Size and Style
If you’re considering a different size or style of a hot water system to your current system, you need to remember that this can come hand in hand with renovation costs. You may need to carry out renovations to the house or fit the system in a different area of your home or expand the space your current system is stored in.
System Type
The biggest decision you’re likely to make when choosing a hot water system is the type. People tend to choose an electric, gas, solar, or heat pump system. Electric systems can have a tank (costing roughly $450 to $1800) or be tankless (ranging between $660 and $1300). Gas systems can also have a tank or be tankless. Gas tank systems cost roughly $850 to $1500, while tankless systems range between $750 and $1600. Solar systems are environmentally friendly and sustainable and come with a price tag of $3600 on average. Heat pump systems will set you back between $3300 and $4000.
Quality
Quality systems tend to cost more than bottom-of-the-range systems. While all systems will be safe and perform as advertised, you can find that better quality systems pay for themselves in the long run, as they’re less likely to require repairs or short-term replacement.
Delivery and installation costs
You’re also going to need to factor delivery and installation costs into your budget. It’s all good and well buying a quality hot water system, but you need it to get to you and be professionally installed if you want to use it. Some suppliers cover delivery costs, while some may charge a fee. Installation costs are non-negotiable, as you may need to call a hot water specialist to install the system effectively and safely.
Disposal of the old system
When calculating how much it’s going to cost you to install a new system, there’s a small fee that you need to be aware of and include in your list of outgoings. This is a disposal fee to remove your old system from your home and dispose of it in a responsible and legal manner.
Rebates and Incentives
Did you know that there are a number of rebates and incentives that you can claim when investing in a new hot water system. These are available on a national and a state level, so you’ll need to do some research to find which are available to you. You could claim up to $1200!
Running Costs
Now, onto the actual running costs of the different types of systems outlined above. There are various factors that can impact the running cost of a system, from system type to its energy star rating. Here are some examples of running costs based on 1 person using 50 litres of heated water a day.
