But where you position the heater can impact its performance and efficiency. Proper placement is key to maximising benefits. In this guide, we’ll explore the optimal locations to install a tankless unit in your home.

With knowledge from experienced Brisbane plumbers, you’ll learn where to place tankless heaters for superior function. We’ll overview popular spots, key positioning factors, and tips to enhance setup. Read on to discover the best places for your new on-demand system.

What Is A Tankless Water Heater?

A tankless water heater offers an efficient alternative to traditional tank heaters. Instead of constantly maintaining a reservoir of hot water, tankless heaters use gas or electricity to heat water on demand. Cold water travels through the tankless unit when a hot water tap is turned on. Advanced heating elements rapidly increase the temperature as the water flows through. This eliminates wait times for hot water.


Tankless systems provide a consistent, unlimited hot water supply for all your needs. Their compact size allows flexible installation in tight spaces. With proper ventilation and gas supply connections, tankless heaters can be installed indoors or outdoors.

By avoiding the standby energy losses of tank heaters, tankless models offer significant energy savings. Their on-demand operation makes them a convenient, eco-friendly option for today’s homes.

Why Choose A Tankless Water Heater?

Tankless water heaters have become increasingly popular in Australian homes due to their many benefits over traditional tank water heaters. A tankless system provides on-demand hot water by only heating it when needed. This eliminates storing hot water in a tank that can lose heat over time.

Going tankless gives you endless hot water for all your needs. You’ll never run out during long showers or when multiple taps are running. Tankless heaters are extremely energy efficient as they avoid constantly reheating a water tank. This saves a significant amount on energy bills.

In addition, tankless units are very compact and can fit in tight spaces where a bulky tank just won’t work. They also have a longer lifespan of 20 years with proper maintenance. You can enjoy temperature-controlled comfort and superior performance with the latest tankless water heater models.


Popular Tankless Installation Spots

When installing a new tankless water heater, a home has several common locations to consider placing the unit. Most tankless systems are wall-mounted to conserve space, although some models can sit on the floor.

A garage or basement is often ideal for installing your tankless unit. This keeps it protected from fluctuating and rare freezing temperatures in the winter. Basements also allow convenient access to gas lines and ventilation. Just be sure to check local building codes for requirements.

Another popular placement is mounting the tankless heater on an exterior wall of the home. This allows for direct venting outdoors. Inner walls bordering a bathroom or kitchen are prime real estate to prevent cold water in distant taps.

You’ll want to avoid putting the tankless system in direct sunlight, which can wear down components quickly. Also, dodge locations near air conditioning lines that could impact performance. Proper placement helps prevent annoying cold showers or fluctuating temperatures.

With some planning, your experienced local plumbers can determine the optimal configuration for your new tankless water heater.

Critical Considerations For Placement

Installing a tankless water heater requires careful planning to find the best location. There are several critical factors to consider for optimal performance.

Proximity to the main water supply lines is essential to prevent heat lost over long distances and provide hot water quickly. Close access to existing gas lines or an electrical panel simplifies hookups.

Ventilation is also key for proper functioning and energy savings. Outdoor installations allow direct external venting but may require insulation. Utility rooms offer indoor ventilation options.

Consider existing plumbing layouts and space-saving mounting. Positioning the unit near high-use areas like bathrooms avoids cold water in distant taps.


An installation site with minimal turns or long water pipe runs will maximise flow. Professional installation ensures proper clearances for ventilation and accessibility.

Analysing heating requirements helps determine the ideal position. Placing the tankless heater in the same location as an old water heater simplifies replacement.

With planning guided by experienced plumbers, you can identify the best location for efficient heating water on demand.

How To Optimise A Tankless Setup

Many homeowners choose tankless systems to save money on energy bills. But installing your tankless water heater in an ideal location is key to optimising performance.

Place the heater close to high-demand areas for the hottest water. Favour easily accessible spots to allow regular maintenance. Meeting all venting requirements also improves efficiency.

Carefully consider the layout when identifying ideal locations. Position the unit to minimise piping distances and turns. This maximises the water flow rate for peak operation.

Maintaining optimal water pressure and temperature settings will ensure comfort and energy savings. Unlike traditional counterparts, tankless heaters require some tuning to unlock their full potential.

Work with professional Brisbane plumbers to analyse your needs. Factoring in requirements for ventilation, accessibility, and existing utilities simplifies installation. Proper placement and configuration will optimise your tankless setup for convenience and energy efficiency.

Connecting The Plumbing And Gas

Installing the required plumbing and gas lines is a key step when adding a new tankless water heater. Proper connections are vital for delivering water and fuel to the system.

Your experienced plumbers will evaluate the optimal location to install your tankless water heater. Nearby access to existing water pipes and gas lines simplifies connections. For outdoor installations, new insulated supply lines may be required.


If mounting the unit on a second floor, additional plumbing considerations come into play. Extra planning ensures adequate water pressure reaches the tankless heater.

Venting the exhaust outdoors is also critical. Your plumbers can install sidewall or roof venting tailored to your perfect spot.

With the right location chosen, connecting the tankless water heater involves linking the cold water intake and hot water outflow to existing pipes. Hooking up the gas line with proper sizing completes the installation.

Proper plumbing and gas fittings ensure your new system has the water supply and fuel to deliver efficient heating on demand.
