Continuous Flow Gas Installation for 2119 Families
Living in Cheltenham often means managing a large, multi-generational household where hot water demand peaks every morning. If your old storage tank is struggling to keep up, switching to a gas instantaneous system—also known as continuous flow—is a practical solution. These compact units, such as the Rinnai Infinity or Rheem Metro series, mount directly to the external wall of your home. They heat water on demand rather than storing it, meaning you never run out of hot water regardless of how many showers are running. For homes in the 2119 postcode, this also frees up valuable floor space in the laundry or backyard. Prices for new gas installations typically start from $1,200, depending on the existing pipework and gas connection capacity at your property.
Reliable Gas Storage Solutions for Large Homes
Many of the sprawling brick veneer homes in Cheltenham still rely on gas storage tanks. Brands like Dux, Rheem, and Aquamax offer high-recovery gas tanks that hold a reservoir of hot water ready for immediate use. This is often the most cost-effective replacement if you already have the plumbing footprint for a tank. We ensure your new storage system is energy efficient, checking the star rating to help lower your running costs. Our team handles the entire process, from disconnecting the old leaking unit to the professional installation of the new tank, including the installation of a tempering valve to ensure water is delivered at a safe temperature to your taps, preventing accidental scalds in family bathrooms.
Local Gas Plumbers for Repairs and Maintenance
Gas plumbing requires a specific licence and a high level of precision, especially when dealing with the older gas lines found in established North Shore suburbs. We specialise in diagnosing pilot light failures, blocked burners, and faulty thermocouples. If you smell gas or notice a yellow flame instead of a crisp blue one, it’s a sign that your system is burning inefficiently or leaking. We carry a range of genuine spare parts for Vulcan, Bosch, and Sanden systems to perform on-the-spot repairs. Regular maintenance every few years can extend the life of your gas hot water system significantly, preventing the internal corrosion that eventually leads to tank failure and water damage.
Energy Efficient Gas Upgrades
With rising energy prices, upgrading to an energy-efficient gas hot water heater is a priority for many Cheltenham residents. Modern 6-star rated units use advanced combustion technology to extract more heat from less gas. When we assess your property, we look at the gas pipe sizing—older 1/2-inch copper pipes may need upgrading to 3/4-inch or larger to support a high-capacity continuous flow unit. Our installations are performed by licensed gas fitters who understand the specific pressure requirements of the Upper North Shore gas network. We focus on providing a system that balances upfront costs with long-term savings on your Jemena gas bill.
Professional Service Across the Upper North Shore
Cheltenham is known for its beautiful, leafy environments and heritage character, which can sometimes present challenges for external plumbing installations. Whether your home is near the Cheltenham Recreation Club or tucked away in one of the quiet cul-de-sacs, we respect your property while working. We ensure all flue clearances for gas systems meet Australian Standards, preventing exhaust gases from entering windows or eaves. From small 16L units for couples to heavy-duty 32L systems for large residences with three or more bathrooms, we provide honest advice on which gas hot water system fits your specific usage patterns and the architectural style of your home.

Frequently asked questions
How long does it take to install a new gas hot water system in Cheltenham?
An instantaneous gas system usually takes 3 to 5 hours to install if we are replacing a similar unit. If you are switching from a large electric tank to a wall-mounted Rinnai or Rheem gas unit, it may take a full day to run the necessary gas lines and upgrade the pipework to meet modern pressure and flow requirements. We aim to have your hot water back on before the evening rush.
Do you provide compliance certificates for gas work?
Yes, all gas hot water installations in the 2119 postcode must comply with AS/NZS 5601.1 standards. As licensed gas fitters, we provide a Compliance Certificate for every new installation. This document is essential for your home insurance and provides a legal record that the gas connections, ventilation, and tempering valves meet NSW Fair Trading safety requirements.
Should I repair or replace my old gas storage tank?
A gas storage tank typically lasts 8 to 12 years in the Northern Suburbs. If you notice rusty water, a pilot light that won't stay lit, or water pooling around the base of the tank, it is likely time for a replacement. We often find that older Vulcan or Dux units in Cheltenham reach their limit around the decade mark due to sacrificial anode depletion.
Are gas hot water systems energy efficient?
Modern 5-star or 6-star gas systems are significantly more efficient than units from fifteen years ago. By switching to a high-efficiency Bosch or Rinnai continuous flow model, you only heat water as you use it. This eliminates the standby heat loss associated with old tanks, which can reduce gas consumption and lower your quarterly energy bills in a busy family household.
