How Much Is That Gas Bill? 5 Tips to Save Big on Gas This Winter

Let’s be honest – no one looks forward to opening their gas bill in the middle of a cold Adelaide winter. If you have ever muttered “How is it that high?” while staring at your energy statement, you are definitely not alone. As the temperature drops, the cost of keeping warm tends to creep up, but the good news is, there’s plenty you can do to take control of that bill (without freezing your socks off). The team at Horncastle Plumbing is an expert at keeping Adelaide homes comfy and cost-efficient, and through this blog, we are sharing some clever tips and tricks to keep your gas bill in check.

At Horncastle Plumbing, we have helped thousands of Adelaide homes stay warm and energy-smart. So today, we are sharing five simple, practical tips to help you use gas more efficiently this winter and keep a little extra in your back pocket.

5 Tips to Save Big on Gas This Winter

1. Get Your Gas Appliances Serviced

Think of your gas heater or hot water system like your car. It needs regular servicing to run efficiently. A well-maintained gas appliance not only works better but also uses less energy. If it’s been a few years (or you can’t remember the last service), it’s time to give our gas fitters a call.

Pro tip: Annual servicing helps catch safety issues, too, like carbon monoxide leaks that can go unnoticed.

2. Upgrade to a Gas-Efficient Hot Water System

Water heating can account for up to 25% of your gas usage, so if your hot water system is old or struggling, it’s probably chewing through gas. We recommend looking at continuous flow (instantaneous) systems or newer 5-star energy-rated models. They heat water as you need it, which means no storage tank and no wasted energy.

Not sure what system suits your home best? Ask us! The hot water plumbers at Horncastle Plumbing are always happy to help you weigh your options.

3. Adjust Your Thermostat (Just a Little!)

This one’s easy: Lower your thermostat by just one or two degrees. Most people won’t even notice the difference in warmth, but you will notice it on your next gas bill. Ideal indoor temperatures for winter are around 18–20°C. Any higher and you are heating more air than you really need to.

4. Stop Heat From Escaping

Your heater might be working overtime because the warm air is sneaking out and the cold is sneaking in. Here is what you can do:

• Use door snakes and draught stoppers
• Close doors to unused rooms
• Check windows and seals for leaks
• Add heavy curtains to keep warmth in
• Small fixes can lead to big savings.

5. Clean or Replace Filters

If you are using a gas ducted heating system or space heater, check the air filters. Dust and grime clog them up, forcing the system to work harder (and burn more gas). Clean filters = better airflow = more efficient heating. When in doubt, give our gas experts a call – we will inspect and clean your system as part of our winter tune-up.

Consider a Gas Audit

Not sure where your gas usage is going? We offer home gas audits for Adelaide residents, checking everything from gas leaks to appliance performance. It’s a smart way to understand your usage and make informed decisions that could save you hundreds.
