Pressure Tanks: The Key to Saving Energy and Protecting Your Hot Water System

When it comes to water systems, Australians have always done things a little differently. While pressure tanks are standard in many countries, they’ve been overlooked in Aussie homes—until now. With modern plumbing systems evolving, GWS pressure tanks are becoming a game-changer, offering protection, efficiency, and long-term savings.

Why Pressure Tanks Aren’t Popular in Australia

1. Old-School Open-Vent Systems: In Australia, many homes still use traditional open-vent hot water systems. These systems allow air and water to escape, preventing pressure from building up—meaning there’s less need for a pressure tank. But as homes move toward more modern, efficient systems, pressure regulation is becoming more important.
2. Not Enough Awareness: The benefits of pressure tanks aren’t always obvious to homeowners or even some plumbers. While systems like solar hot water or heat pumps can benefit a lot from pressure tanks, many people just aren’t aware of how they can help.
3. No Legal Requirement: Unlike in places like North America or Europe, Australian regulations don’t require pressure tanks for most systems. This has meant that, for a long time, they’ve just been overlooked as a necessary part of water systems.
4. Other Pressure Control Methods: Instead of pressure tanks, Aussie homes often rely on pressure relief valves (PRVs) or other simple methods to control pressure. While these are fine in the short term, they don’t offer the same long-term benefits that pressure tanks can provide, like reducing pump wear and water hammer.

The Dangers are Real

Ever wondered just how much pressure a water heater can handle? The MythBusters put it to the test in an explosive experiment, showing what happens when pressure relief fails. Spoiler: it’s not pretty! This dramatic demonstration highlights why managing water pressure is so important. While the video proves how dangerous unchecked pressure can be, a GWS pressure tank keeps your system safe by absorbing excess expansion—so you never have to worry about your water heater turning into a rocket. 

Why GWS Pressure Tanks Are a Game-Changer for Aussie Homes

Now, why should Australian homeowners consider GWS pressure tanks? Here’s why they’re the perfect match for modern systems and homes:

1. Steady Water Pressure: The main reason to consider a GWS pressure tank is to keep your water pressure consistent. Fluctuating water pressure can be annoying, especially when you’re trying to use multiple taps at once or when your hot water system isn’t performing as expected. GWS pressure tanks make sure the water flow stays smooth and reliable.
2. Save Energy: One of the hidden perks of using a pressure tank is energy efficiency. Because the pressure tank stores pressurized water, your pump doesn’t have to turn on and off constantly. This means less wear on your pump, lower energy costs, and fewer maintenance headaches.
3. Perfect for Modern Systems: Whether you're using a solar hot water system, heat pump, or booster pump, a GWS pressure tank works beautifully. For example, in solar hot water systems, the pressure tank ensures you always have a steady water supply, even when the mains water pressure isn’t reliable.
4. Protect Your System: Excessive pressure can cause a lot of problems—things like leaking pressure relief valves, burst pipes, and system failures. A pressure tank helps absorb any extra volume, preventing pressure from building up to dangerous levels. If you have a closed-loop system, the pressure tank is a must to keep everything running smoothly.
5. Versatility: GWS pressure tanks aren’t one-size-fits-all. They work across a variety of systems, from underfloor heating to hot water systems. Whether your home has a traditional setup or something newer, a GWS tank helps maintain optimal pressure and protect your system from damage.
6. Easy and Cost-Effective: Pressure tanks might seem like an added expense, but they’re actually a cost-effective way to improve the performance and longevity of your water system. They’ll save you on energy costs, reduce the need for repairs, and keep your system running efficiently for years to come.

Why GWS Pressure Tanks Are a Smart Investment

As more Australian homes switch to closed-loop plumbing systems, the need for pressure tanks is growing. If you want to ensure your water system runs smoothly, efficiently, and safely, GWS pressure tanks are an excellent choice.

They provide steady water pressure, protect your system, save you money on energy, and improve the overall performance of your hot water or heating system.
