Are you considering getting a new hot water unit installed and wondering whether you should change its location? Or perhaps you are building a new house and want to know the best spot for your new hot water system. Choosing the right spot for your hot water system isn’t just about convenience—it affects energy efficiency, safety, and long-term costs.
Several factors influence the ideal location, and in this guide, we’ll explore them all. We’ll also look at the best locations for different types of hot water systems, giving you all the information you need to be able to make an informed decision for the most reliable and cost-effective setup.
Picking the perfect spot for your hot water system is more than just seeing where it best fits. There are several factors to take into consideration to ensure it runs efficiently and safely. For example, it makes sense to place it closer to your kitchen and bathrooms, which means you waste less heat and water while waiting for it to reach the hot water tap. No one likes waiting for a hot shower to heat up.
If you’re installing a gas water heater with your existing plumbing, you should consider ventilation to prevent dangerous fumes from building up. You’ll also need to check local building regulations to make sure your setup meets safety standards.
Finally, you’ll need enough space for easy installation and maintenance. One of the best ways to get longevity from your hot water system is regular maintenance—once every two years is a good general rule.
You may have noticed that some households have their hot water systems installed outside, while others keep them indoors—why is that? And does it really make a difference?
The answer depends on your home’s layout, climate, and the type of system you’re using. Indoor installations protect the unit from harsh weather, making them suitable for colder climates. However, they require proper ventilation, take up space, and may not suit your interior aesthetic.
Outdoor systems free up room inside and are great for warmer areas but may need extra insulation in winter. The right option depends on your climate, convenience, and what works best for your home.
Here are the most popular locations for hot water systems and why they’re suitable.
The garage or utility room is an ideal location for a hot water system, as it’s protected from the elements while staying out of sight from the main living areas. It also provides easy access for maintenance, especially for storage tank systems. However, it requires adequate ventilation (especially for gas hot water systems) and could potentially take up valuable storage space or get in the way of opening car doors in tight garages.
For smaller homes or apartments, placing the system in a laundry room or kitchen can be a space-saving solution. However, noise and heat output may be concerns, and plumbing adjustments may be needed.
Outdoor installation is common for gas hot water systems as it eliminates the need for ventilation. It is generally safer because it reduces the risk of gas buildup or carbon monoxide exposure. Electric hot water systems can also be installed outside but may require additional weatherproofing.
Some homes install hot water units, especially gas instantaneous systems, under the house or in the roof space to save space. While it is effective because it’s protected from the elements while out of sight, access for repairs can be difficult, and heat loss may be a concern if not well insulated.
If you are considering installing a gas or electric hot water system, as we’ve mentioned, placing it closer to bathrooms and kitchens reduces heat loss through long pipe runs. As a result, less energy is needed to deliver hot water where it’s needed. Choose a location close to your kitchen and bathrooms while still allowing for safe and practical installation.
If, however, you’re installing a solar hot water system, roof placement with optimal sun exposure is key to maximising efficiency. You are best to consult an expert hot water system installer for the best placement for solar panels and solar water heaters.
Some materials and devices can help you reduce energy consumption. Consider insulating pipes, using timers and smart controllers. Investing in these, as well as an experienced hot water system installer, will ensure your system is appropriately set up for maximum energy efficiency, saving you money on your energy bills.
When installing a hot water system, safety and compliance are non-negotiable. Australian Standards dictate where and how systems can be installed to ensure safe operation.
There is compliance required around gas systems, where placement must follow minimum distance requirements from gas meters, electrical panels and flammable materials to prevent hazards.
Accessibility is another key factor—installing your system in a spot that allows for easy future maintenance and servicing will save you headaches down the track, and potentially extra costs charged by your electrician. A professional installer will provide peace of mind by not only advising on the cheapest hot water system to run, but ensuring your system meets all legal requirements while making safety a top priority.
Choosing the best location for your hot water system can significantly impact its efficiency and longevity. For different home types, some locations work better than others—like garages or utility rooms for easy access, or outdoor spaces for gas systems. Optimising hot water delivery speed and ensuring future-proof installation choices are also crucial for long-term savings.

The best placement for a hot water system is in an accessible location that minimises heat loss, complies with safety regulations and ensures easy maintenance.
The best placement for a heat pump system is in a well-ventilated area, ideally outside, where it can efficiently draw in air for heating while minimising noise and exposure to harsh weather conditions.
Ideally, your hot water tank should be placed in an accessible area like a garage or utility room, where it’s protected from the elements but not in direct view inside the home.
The location of a water heater matters as it impacts energy efficiency, safety, accessibility for maintenance, and compliance with local regulations. For best practice, aim for close to hot water outlets.
