Gas Hot Water System Installation: Is It the Right Choice for You?
It’s a chilly morning. You turn on the shower, and boom, cold water hits you. If you’ve been dealing with slow, weak, or just plain cold water, it might be time to think about an upgrade.
Many Aussie homes are switching to gas hot water systems for a reason: they’re fast, reliable, and can save money in the long run.
But is a gas hot water system installation really the right choice for you?
What Is a Gas Hot Water System?
A gas hot water system uses natural gas or LPG to heat your water. You can choose from a gas hot water tank (which stores hot water for use) or an instant gas hot water system (which heats water as you need it, no storage tank required).
Both are great options depending on your home size, water usage, and energy bills.
Why Install a Gas Hot Water System?
Thinking about making the switch? Here are some simple reasons why more people are choosing gas hot water system installation:
1. Fast Heating
Gas heats water faster than electricity, which means quicker showers, especially helpful for big families.
2. Cheaper to Run
Natural gas is often cheaper than electricity in Australia, so your energy bills might go down.
3. Works in Power Outages
Gas systems still work when the power goes out. That’s a big plus during storms or blackouts.
4. Endless Hot Water
With an instant gas hot water system, you never run out. Great for busy households.
What Happens During a Gas Hot Water System Installation?
Let’s say you’ve made up your mind. Here’s what a gas hot water system plumber will usually do:
- Inspect your home to check where the unit should go and what kind you need.
- Remove the old system – if you’re replacing an electric or broken unit.
- Install gas lines – or check existing ones.
- Fit the system – this could be a gas hot water tank installation or a wall-mounted instant unit.
- Test it all – making sure everything is safe, working, and leak-free.
Gas Hot Water System Options: Which One Should You Pick?
You’ll usually choose between:
Storage Tank System: Heats a large amount of water and stores it. Best if your water use is spread out through the day.
Instant Gas Hot Water System: Heats water as you use it. Great for small homes or places with lots of back-to-back showers.
Your gas hot water system plumber can help you choose the right size and model based on your family size and lifestyle.
Cost of Gas Hot Water System Installation
Here’s a rough idea:
- Gas hot water heater installation cost: Starts from around $1,000–$2,500 (including the unit and labour).
- Running costs: Often lower than electric systems in the long run.
- You may also be eligible for rebates or incentives if switching from electric.
