How Gas Hot Water Works
Gas water heating systems use natural gas or LPG as an energy source to heat water. These systems come in two main options: a storage tank or a continuous flow water heater that heats water on demand.
A continuous flow gas water system heats water only when and where you need it. This eliminates heat loss from a storage tank and saves you money by not paying to constantly heat a cylinder full of water. These systems are also space-saving and can be installed in various locations, making them ideal for homes or buildings with limited space.
Gas water heaters are more efficient than electric water heaters, as they heat water faster, use less energy, and the fuel source is less expensive.
Gas Hot Water FAQ
A gas continuous flow system heats water on demand as it passes through the unit — no storage cylinder needed. When you turn on a hot tap, the gas burner fires up instantly and delivers a constant stream of hot water, meaning you’ll never run out mid-shower. The Rinnai Infinity A26 is one of our most popular units for exactly this reason.
