How to Replace a Water Heater?

If your hot water system is leaking, taking too long to heat up, or simply past its prime, it might be time for a replacement. Knowing how to replace a water heater can help you avoid cold showers, reduce your energy bills, and ensure your home runs smoothly. At Team Penguin Plumbing, we’re here to guide you through what’s involved in the process.

When Should You Replace Your Water Heater?

Here are some signs it might be time to upgrade your unit:

• Water isn’t as hot or consistent as it used to be
• Rust-coloured or dirty water comes from your taps
• Strange noises like banging or rumbling
• Leaks around the base of your unit
• Your unit is more than 8–12 years old

If you’re wondering how much water heaters cost to replace, the answer depends on the type of unit, its size, and whether extra plumbing or electrical work is needed. On average, you can expect to pay between $1,200 and $3,000 in Australia, including supply and installation.

Steps to Replace a Water Heater

1. Select the Right Water Heater

First, choose a system that suits your household’s size, water usage, and energy preferences. Common types include:

• Electric storage – Simple and affordable for small homes
• Gas storage – Good for households with higher hot water demand
• Instantaneous (continuous flow) – Heats water only as needed
• Heat pump or solar – Energy-efficient options with long-term savings

2. Turn Off Power and Water Supply

Before you begin, switch off the power or gas supply to your water heater and shut off the main water supply to prevent leaks and accidents.

3. Drain the Tank

Connect a garden hose to the drain valve at the bottom of the tank and run it to a safe drainage area. Open the valve and allow all water to drain out. Be cautious,the water may still be hot.

4. Disconnect and Remove the Old Unit

Once drained, disconnect all plumbing and electrical or gas connections. Carefully remove the old water heater,this may require two people or a plumber, as the unit can be heavy and awkward to move.

5. Install the New Water Heater

Place the new unit in position, ensuring proper clearance and ventilation if needed. Connect all water lines and fittings securely. If you’re installing a gas system, it must be connected by a licensed gas fitter.

6. Refill and Test

Turn the water supply back on and allow the tank to fill completely. Once filled, restore power or gas and test the unit for leaks. Allow some time for the water to reach the desired temperature.

How Long Does It Take to Replace a Water Heater?

A standard replacement usually takes between 2 to 4 hours. This can vary depending on the type of system and whether any upgrades or modifications are needed. If you’re switching from electric to gas or moving the location of your unit, allow extra time for the additional work.

DIY or Call a Pro?

While some handy homeowners may feel comfortable replacing a water heater themselves, it’s important to consider safety and compliance. Gas connections, pressure valves, and temperature settings must meet strict regulations in Australia. Improper installation can lead to serious risks and void your warranty.

That’s why it’s best to call in the professionals at Team Penguin Plumbing.
