Tankless Hot Water Systems Gladesville 2111
Gladesville residents often deal with the spatial constraints of established harbourside blocks where every square metre of land is valuable. Replacing a bulky, rusted storage tank with a compact tankless system allows for more usable outdoor space while providing a constant supply of hot water for busy households near Victoria Road.

Space-Saving Solutions for Gladesville Harbourside Living
Gladesville features a diverse mix of housing, from original Federation brick homes to the medium-density apartment blocks commonly found near the shopping precinct. In these 2111 properties, space is often at a premium. A traditional 315-litre electric storage tank takes up roughly one square metre of floor space and usually sits in a prominent position in the backyard or laundry. By switching to a tankless or continuous flow system, we mount a small unit—similar in size to a carry-on suitcase—directly to the external wall. This freeing up of space is particularly beneficial for narrower blocks where side-access is limited or for homeowners looking to maximise their courtyard area for entertaining.
Endless Hot Water for Growing 2111 Households
The primary advantage of an instantaneous system is the delivery of endless hot water. Unlike storage units that can run dry after two long showers, a tankless unit heats water on demand as it passes through a copper heat exchanger. Brands like Rinnai and Rheem have perfected this technology, ensuring that even if multiple taps are running, the temperature remains stable. For larger family homes in the leafy streets of Gladesville, this eliminates the morning rush for the shower. These systems are rated by flow rate, typically ranging from 16 to 32 litres per minute, allowing us to select a model that suits the specific number of bathrooms in your residence.
Reducing Energy Bills with On-Demand Heating
For many Gladesville homeowners, energy efficiency is a significant driver when upgrading plumbing fixtures. Older electric storage heaters are notorious for 'standing heat loss,' where energy is wasted keeping 300 litres of water hot overnight while nobody is using it. Tankless systems only activate when a hot tap is opened. This on-demand heating method can significantly reduce gas consumption, especially in households that are empty during the work day. Most modern units carry 6-star or 7-star energy ratings, making them some of the most efficient water heating options available on the Australian market today.
Professional Installation and Brand Expertise
Quality installation is critical for the longevity of a continuous flow system. At Infinity Hot Water, we handle the full transition, which often starts from $2,200 depending on the specific site requirements. If your Gladesville home is currently using an old Dux or Vulcan tank, the gas lines may need a slight upgrade to accommodate the higher megajoule input required for tankless heating. We also ensure that the unit is positioned correctly to meet NSW gas regulations regarding proximity to windows, doors, and vents. Our team carries a wide range of parts and units for major brands including Bosch, Aquamax, and the high-efficiency Sanden or Reclaim heat pumps for those looking for sustainable alternatives.
Durability and Long-Term Value in the Northern Suburbs
While a standard glass-lined storage tank might last 8 to 12 years before the sacrificial anode fails and the tank bursts, a high-quality tankless system is built to last significantly longer. Because they don't store water, there is no internal tank to corrode. The components inside a Rinnai Infinity or a Rheem tankless unit are designed for durability, with many units exceeding a 20-year service life when maintained correctly. This makes the initial investment much more cost-effective over the long term for property owners in the Northern Suburbs, providing reliable performance year after year without the risk of a catastrophic flood from a leaking tank.

Frequently asked questions
How long does it take to install a tankless system in Gladesville?
Most tankless installations in Gladesville homes take between 3 and 5 hours. If we are replacing an old storage tank, we need to decommission the unit, modify the pipework for a continuous flow setup, and often upgrade the gas line to handle the higher megajoule rating required for instantaneous heating. We carry all necessary parts to ensure your hot water is back on before we leave your property.
Are tankless systems more energy efficient for Northern Suburbs homes?
Gas continuous flow models like the Rinnai Infinity or Rheem Metro are highly efficient because they only burn fuel when a tap is turned on. For Gladesville residents on the natural gas network, this typically results in lower quarterly energy bills compared to old electric cylinders that heat water 24/7. Because these units don't store water, there is no heat loss through the tank walls, making them a primary choice for sustainable home upgrades.
Do I need to upgrade my gas lines for an instantaneous system?
In many of the older 2111 postcode residences, the existing gas pipes are 15mm or 20mm. High-capacity tankless units often require a 20mm or 25mm gas line to provide enough flow for the burners to achieve 'endless' hot water. During our initial site inspection, we check your gas meter and pipe diameters to ensure the system will perform at its full rated capacity without starving other appliances like your cooktop.
What maintenance do these systems require?
While tankless units have fewer components prone to rust than storage tanks, they still require a service every two years. In the Northern Suburbs, mineral buildup can occasionally affect the heat exchanger. A routine flush and a check of the internal filters and sensors will typically extend the lifespan of a Rinnai or Bosch unit to 20 years or more, effectively doubling the life of a standard electric tank.
