As the temperatures drop across Noosa, the Sunshine Coast and Gympie, your hot water system has to work harder than it does during the warmer months. Colder mains water means your gas hot water system uses more energy to deliver the same hot shower.

The good news? Whether you have a gas storage hot water system or an instantaneous (continuous flow) gas hot water system, there are simple ways to reduce your gas usage while still enjoying reliable hot water all winter long.

At Gas Services QLD, we install, repair and service gas hot water systems throughout the Sunshine Coast, Noosa and Gympie regions. Here are our top winter hot water saving tips.

Why Do You Use More Hot Water in Winter?

Many homeowners notice higher gas bills during winter and assume something is wrong with their hot water system.

In reality, the water entering your home can be significantly colder during winter. Your gas hot water system needs to heat that water by a greater temperature, meaning it burns more gas to achieve the same result.

Combined with longer, hotter showers, winter naturally increases household hot water usage.

Tips for Gas Storage Hot Water Systems

Gas storage systems keep a tank of heated water ready for use. While they recover faster than electric storage systems, they can still run out if demand is high.

1. Keep Showers Short

Reducing showers to around five minutes can dramatically decrease hot water usage without sacrificing comfort.

2. Space Out Multiple Showers

If several family members shower back-to-back, give your storage system 10–15 minutes to recover between showers where possible.

3. Wash Clothes in Cold Water

Modern detergents work exceptionally well in cold water. Saving hot water for showers and household use reduces unnecessary gas consumption.

4. Fix Dripping Hot Taps

Even a slow drip continuously wastes heated water, causing your system to cycle more often.

5. Service Your Gas Hot Water System

A poorly maintained burner or gas control can reduce efficiency and performance. Regular servicing keeps your system operating safely and efficiently.

Tips for Instantaneous (Continuous Flow) Gas Hot Water Systems

Continuous flow systems only heat water when you turn on a hot tap, making them one of the most energy-efficient hot water options available.

However, there are still ways to maximise efficiency.

1. Use Water-Efficient Shower Heads

Less water flowing through the system means less gas is required to heat it.

2. Avoid Running Multiple Hot Taps

If several hot taps are operating simultaneously, particularly in larger homes, your system may struggle to deliver maximum flow and temperature.

3. Don’t Set the Temperature Too High

Many homeowners increase the thermostat unnecessarily. A comfortable setting reduces gas consumption while still providing plenty of hot water. Tip – a licenced gas fitter plumber will need to assist with this.

4. Keep the Unit Serviced

Annual servicing helps ensure burners, heat exchangers and gas components remain clean and efficient.

Winter Hot Water Saving Tips for Every Home

Regardless of which type of gas hot water system you own, these simple habits can reduce your gas usage.

• • Install water-efficient shower heads.
  • Repair leaking hot water taps promptly.
  • Insulate exposed hot water pipework.
  • Avoid unnecessarily long showers.
  • Only run the dishwasher or washing machine with full loads.
  • Upgrade ageing hot water systems that have become inefficient.

Is It Time to Upgrade?

Older gas hot water systems often become less efficient over time.

If your hot water is inconsistent, your gas bills have increased, or your system requires frequent repairs, replacing it with a modern high-efficiency gas hot water system could save money over the long term.

Our licensed gas fitters can help you choose the right storage or continuous flow system for your household and install it safely in accordance with Australian Standards.
