How gas hot water storage systems work
A gas storage system heats and stores water in an insulated tank, ready to use whenever you turn on the tap. Inside the tank, a gas burner and heat exchanger work together to keep the water at your chosen temperature, ensuring hot water is always available — even during peak times.
As you use the hot water, cold water flows in from the bottom, and the burner automatically ignites to heat it again. This continuous heating process means you’ll never be left waiting for your shower to warm up.
Efficient and easy to maintain
Modern gas hot water heaters like the Rinnai Hotflo are built for energy efficiency and durability. The system’s storage tanks are made from tough, long-lasting materials that resist corrosion and maintain water temperature with minimal heat loss.
You’ll also enjoy the benefits of mains pressure delivery, giving strong, steady water flow to multiple taps or appliances at once. Plus, with automatic temperature control and simple operation, your family can enjoy safe, comfortable hot water every day.
Choose the right size for your family
The Rinnai Hotflo gas storage systems come in two sizes to suit your household’s needs:
- 135L system – perfect for smaller households or those with moderate hot water use
- 170L system – ideal for families or homes with higher demand.
Both models offer quick recovery times, so your hot water supply stays ready when you need it most. Our team can help you choose the right tank size for your home, ensuring efficient operation and lower energy costs over time.
