Unit size and type
The price of a hot water system varies depending on what type of system you want. There are four main types along with different sub-types you can choose from. You have electric, gas, solar and heat pumps.
Each of these has its own subcategory. Electric storage, instantaneous, gas storage, gas instantaneous, solar split system electric boost, solar split system or a gas boost.
Hot Water Systems
Water is heated and then stored in the tank and is ready to be used. Heating is done through an element at the bottom of the tank.
Electric Continuous Flow (Instant)
Water is heated only when it is required. They are often known as 'tankless water systems'.
As with electric hot water systems, gas water heaters come in both tankless and storage systems. Water is heated through a burner.
These systems generate heat from the sun. They use panels that are mounted on the roof.
They are similar to Solar units with the difference being that water is heated by using air conditioning technology. Heat is extracted from the ambient air and used to heat the water. They are mostly installed outdoors and need a warmer climate.

Electric – “Instant” type $660 $1300
Gas – “Storage” type $850 (135L) $1500 (360L)
Gas – “Instant” type $750 $1600

Heat Pump $3300 (160L) $4000 (315L)
Each hot water system company or plumbing team works differently when it comes to their pricing and how they calculate the costs involved for the job. Some companies will factor in the size of the unit. The price for a tank that is only 15 kg may differ to a large 350ml tank that will require more than 1 technicians
The cost for installation of your new hot water system can change depending on how complicated the works are to complete.
A lot can change during the installation process and you need to keep that in mind. Variables such as the time to complete the installation can take longer than expected. A standard straight swap shouldn't take longer than 2 hours but it is always best to leave room for unforeseen changes.
If you are changing your energy source from gas to electric or vice versa, the length of time will increase because additional works will be needed. You may also need upgrading of your plumbing or electrical systems during the installation process.
As well as changing the position of the water heater to a different area of your property. Ensuring the tank fits correctly requires time.
Relocating a water heater or changing its energy source will impact the costs involved.
When installing hot water systems, having clear access will make all the difference in the pricing involved. Larger, commercial-sized tanks may need cranes and heavy lifting equipment. High roofs and tight staircases could prove difficult and may need extra labour costs.
You can receive incentives from the Australian government when you purchase new water heaters. Solar units, in particular, have significant incentives that can lower the pricing of purchasing and installation.
You can ask your licensed plumber to provide you with additional disposal costs. Correct and responsible disposal of your old tank is required and can be added to your quotation.
