Who doesn’t care about money in this economy? It’s only smart to check the cost of everything before committing, and home appliances are no exception. The last thing you want is to end up with an overpriced system that drains your wallet.
That’s why researching hot water system prices is a must, unless you don’t mind costs an arm and a leg. Luckily, we’re here to break them down for you. From installation fees to hot water plumbing service charges, let’s explore what you should expect!
Initial Costs of Hot Water Systems

For the initial cost, prepare for the hot water system cost. This will depend on the types of hot water systems you choose. Also, keep in mind that there will be installation costs, which can vary based on your location.
Hot Water Systems Price
Types | Price Range |
Electric | $400 – $2,000 |
Gas | $700 – $2,000 |
Solar | $2,000 – $7,000 |
Heat Pump | $2,500 – $4,000 |
Yes, it can be pricey, but you definitely don’t want to experience low hot water pressure, do you? Investing in a high-quality hot water system is the best way to avoid that frustrating issue, we promise.
Installation Cost
The hot water system installation cost will depend on your system and any additional work. In Melbourne, it typically ranges from $1,000 to $7,000. If you need modifications or upgrades, the cost could be higher.
Ongoing Costs of Hot Water Systems
You’ve covered the upfront costs, but what about the day-to-day expenses? Let’s discuss it.
Energy Costs
Wondering how much your system is going to rack up on your energy bill each month? We get it—it’s a big deal! But the good news is, with a few smart moves, you can keep those costs in check.
Here are some simple tips to lower your energy costs:
- Turn down the thermostat: Heating water at a lower temperature can save you a bundle over time.
- Insulate your hot water tank: Keep that heat locked in, so the system doesn’t have to work overtime.
- Upgrade to water-efficient fixtures: A low-flow showerhead or tap means less water to heat—and more money saved.
- Skip the hot settings: Wash your clothes in cold water to reduce how much your system works.
And if you want to go far to save water costs, here’s a hot tip: go solar. Yes, we know it’s expensive at first—but it’s totally worth it.

Once it’s up and running, your energy costs will be much lower than with electric or gas systems.
Typical monthly energy costs for non-solar systems range from $100 to $800 a year. With solar, though, you’ll see a big cut in those numbers!
Maintenance Costs

Let’s face it—nobody likes dealing with maintenance, but trust us, it’s crucial for the lifespan of hot water systems. On average, you’ll pay between $100 and $300 a year for professional maintenance, depending on the type of system you’ve got.
If you know the electric hot water system prices, which is the most affordable type, it’s still much more costly than maintenance cost. That’s why, it’s better to do hot water system maintenance regularly to prevent any complicated issue.
Repair or Replacement Costs

Nobody wants to deal with a malfunctioning hot water system, but when things go wrong, it’s best to act fast since it will affect how long they take to heat up.
Now, when it comes to the hot water system replacement cost, it all depends on what’s broken. Some of the most common fixes include:
- Thermostat: If this goes, you’re looking at $100 to $300 to fix.
- Heating element: A faulty one will set you back between $200 and $500.
- Pressure relief valve: If the pressure’s off, you’ll need $20 to $200 to get it sorted.
And if you’re facing a total system breakdown? Replacing the entire thing will run you anywhere from $400 to $7,000, depending on the type of system.
Average Total Costs of Hot Water Systems

Now that you know the details of each cost, it’s time to sum up the total amount you’ll be spending. The average water heater price, including installation, can range from $1,000 to $5,000, depending on the type you choose.
But that’s just the beginning. Once your system is up and running, you’ll also need to consider ongoing energy costs.
On average, you can expect to spend around $30 to $100 per month on heating, depending on how energy-efficient your system is. Over the course of a year, that adds up to roughly $360 to $1,200.
So, while the initial expense might seem high, keep in mind the long-term costs to help you make the most budget-friendly choice!
