Price Breakdown: The Average Cost of Hot Water Repairs and Installation In Melbourne

How Much Does It Cost To Unblock A Drain In Melbourne 2021 2

One of the main purposes of having an efficient water system is so that there is hot water available. Nobody likes taking cold showers in the morning, and hot water is needed for a variety of different reasons. 

However, there is a great variance in terms of the cost when you account for the different systems and their size. Below, we’ll explain some of these systems and how much they cost to purchase, repair, and install

The Major Types of Hot Water Systems


Broadly speaking, there are 3 major kinds of water systems. These are:

  1. Electric.
  2. Gas.
  3. Solar.


Electric systems are the cheapest, followed by gas, and finally solar. However, the cost of purchase is proportional to the savings. So while solar is the most expensive to install, it could be the cheapest over the long term as it can save on water bills. 


Electric and gas hot water systems come in 2 types – instant and storage. The instant type has no tank and the water is heated on demand. These are useful if you use a limited amount of hot water. Not so good if you want to luxuriate in a bath or have a large family. A storage tank of hot water is best for this. 

Solar hot water systems are typically roof mounted with an electric or gas boost for times when there is insufficient sunshine. Split systems will be roof mounted but with a storage tank on either the roof or the ground. 

Hot Water System: Average Cost Melbourne

Now that we are familiar with the different types of water systems, let’s look at the cost for each type. Remember to take account of the fact that, while some types are more expensive, they will reduce your energy bill. Look at it as an investment instead of a sunk cost. This table accounts for the system itself – not for installation or additional costs.

How Water System Installation: Average Cost Melbourne

Installation costs for hot water systems will vary greatly, depending primarily on what type of system you are having installed. Generally, the more complex and sophisticated the system, the more expensive it will be to install. The installation of solar hot water systems will cost you more than other systems, simply because it is on the roof and more difficult to access. 

But, for the majority of installs, the costs should be in the region of $200 – $300. This is for the most simple install where everything runs smoothly. It will take around 2.5 hours to install, and the average hourly plumbing rate in Melbourne is $80. 

If it is an older model or if the install requires more time (as often happens), the installation can take up to 5 or 6 hours, and may even require a revisit the next day. It might be best to allow $300/$400 when budgeting for your new hot water system installation. If you aim a little high, it might give you a pleasant surprise when the cost is lower or allow you to deal with additional costs more easily.

How Water System Repairs: Average Cost Melbourne

The cost of hot water repairs in Melbourne will be similar to the cost of installation in many instances. You can expect to pay a base hourly fee and callout fee. For a simple repair, you can expect to pay around $200 inclusive of the callout fee and the hourly rate. Additional parts might cost around $50 extra.

Of course, if you need a new installation or a major replacement, the cost will be extra. Repairs can usually be carried out pretty quickly, as you will be working with a plumber familiar with the hot water system. Don’t call a plumber to fix your solar split system that is not experienced in working with them. It will add to the time needed for the repair and you should look for CEC certified installers. 

Hot Water Repairs & Installation Cost: Summary

How can I save money on hot water repairs & installation in Melbourne?

Work with a provider who is experienced with the installation of the same type of hot water system. This way, the installer will know exactly what they are doing and you can get it installed without hassle in 2 or 3 hours. This will almost certainly cut down on installation costs. The same applies for repairs. If you work for a plumber that specialises in that exact system, you will save cash and potential stress. 

What factors affect the price of hot water systems?

The biggest factors would have to be the type of unit and the size. A small electric system is going to be a fraction of the price of a solar split system with an electric boost. Aside from this, you have delivery and installation costs. Installation costs will potentially be increased if the site is difficult to access. You may also have to pay to dispose of the existing water system. On the other hand, you can save money on the total price using government rebates, though this is mainly for solar powered systems. 

How much does it cost to run the hot water system?

The typical cost to run a hot water system would be $800 – $1000 for an electric system, $200 – $500 for gas, and $100 – $400 for solar. But there are many factors affecting this, including the current tariff rates, instant vs storage, the efficiency rating of the system, etc.
