Why Choose Rinnai Hot Water Systems?
For over 50 years, Rinnai has been a trusted and reliable brand in Australia, providing long-lasting hot water solutions for all kinds of homes. With decades of innovative Japanese engineering, Rinnai hot water systems are known for their energy efficiency, reliability and systems that are built to withstand the unpredictable Melbourne weather.
One of the main draws for Rinnai hot water systems is the wide range of technologies available. Depending on your property, you can choose between continuous-flow gas systems to electric, solar and heat pump hot water systems.

Types of Rinnai Hot Water Systems We Supply & Install
Rinnai offers several different types of hot water systems, each designed for your home and usage habits.
Electric Hot Water Systems
Electric hot water systems are a popular choice for many Melbourne households. These systems store heated water, are simple to install and are very cost-effective. They are suitable for Melbourne properties that don’t have access to gas connections.
Solar Hot Water
Solar hot water systems use the natural energy from the sun to heat your home’s water. They help Melbourne households to cut down on their overall electricity costs and consumption and help to improve your carbon footprint.
Continuous Flow Gas Units
Gas hot water systems use natural gas or liquefied petroleum gas (LPG) to heat water for your home. Rinnai gas systems are known for their fast recovery rate, energy efficiency and are easy to install.
Heat Pump Hot Water Systems
A common question we get is “Will my heat pump work properly in the Melbourne winter?” As we all know, Melbourne winters can be brutal and often go below freezing. Luckily, Rinnai’s heat pumps are ready for the challenge and feature de-frost technology. They also draw ambient heat from the outdoor air even if temperatures are well below freezing, ensuring you have a constant and reliable source of hot water.

Whether you’re building a new home, in the middle of a renovation or just want to upgrade to a more efficient hot water unit, WP Plumbing is here to help. Our plumbers supply and install a range of Rinnai hot water systems, tailored to your needs, budget and lifestyle.
Our team works with you to figure out what Rinnai system is best for you and will also:
- Install your new hot water system safely and with confidence

- Test and commission the new unit
- Dispose of your old system properly and sustainably

Repair Or Replace? What Should I Choose?
This is another common query we get from Melbourne homeowners and we get it; it’s a big decision to make. While it might be easier to sit and hope for the best and continue to use a faulty hot water system, our plumbers don’t recommend this.
Instead, consider these factors:
Repairing Your Rinnai Hot Water System Makes Sense If
- Your system is relatively new
- The issue concerns only one or two components
- The replacement parts you need are available
- The system still meets your household’s needs and requirements
- The repair cost is reasonable when compared to replacement
Replacing Your Rinnai Hot Water System Makes Sense If
- Your system is getting older
- You’re experiencing frequent breakdowns and malfunctions
- Repair costs keep adding up
- Your unit is leaking or badly corroded
- You need an upgrade to accommodate your home’s growing needs
- You want to change the type of system you have
It’s also worth considering the cost of continuing to service and repair your old system. A cheaper repair today might not be the most economical choice later down the track.
At WP Plumbing, we can assess the condition of your existing Rinnai hot water system and guide you through the inspection process, helping you to decide whether a repair or a replacement is the best way to go.

Rinnai Hot Water Maintenance Services
Investing in regular maintenance is essential to keeping your Rinnai hot water system working smoothly. Our hot water plumbers will inspect the entirety of your hot water unit to check for potential problems like leaks, mineral build-up and the water connections. Being proactive in this way helps you to save not only time but money as well.
Rinnai Hot Water Systems For Melbourne Apartments & Townhouses
With limited space and access to gas and electricity, it can be tricky to know what hot water system is best for Melbourne apartments and townhouses. Our hot water plumbers talk you through your options and consider factors such as:
- Available installation space
- Body corporate rules and regulations
- Access for future maintenance and servicing
- Noise leakage from heat pump systems
- Your apartment or townhouse’s electrical capacity
- Shared hot water infrastructure
- The location of the system.
When installing a Rinnai hot water system in an apartment or townhouse, it is important to check the existing plumbing infrastructure and choose a system that suits its requirements as well as your needs.
How Long Do Rinnai Hot Water Systems Last?
On average, Rinnai hot water systems last between 8 - 20 years, depending on the type and how often you service it. However, it’s never a one-size-fits-all solution and will depend on your unique situation, your water habits, water quality, system type and the environmental conditions of your property.
How Do You Choose The Right Rinnai Hot Water System?
Choosing a Rinnai hot water system isn’t just about picking the newest model or the most powerful one. The right system needs to match your home’s hot water demands and available energy source.
Before choosing a Rinnai hot water system, our plumbers go through:
- Household Size & Hot Water Demand: A studio apartment obviously has less water demand than a free-standing family home. Think of how many people shower each morning, whether you have multiple bathrooms and how much water you use for everyday activities.
- Available Space: The location of your current hot water system can also influence your options. This is especially important for Melbourne apartments, townhouses and smaller studios where outdoor space is limited.
- Existing Energy Source: A new hot water system can be a totally different make, model and type to your old one. Different systems need different plumbing, gas, electrical and installation needs.
- Future Plans: Are you planning on renovating or growing your family in the future? Your hot water system needs to reflect that and have enough capacity to keep up.
