Urgent Repairs

Nothing compares to waking up on a cold winter’s morning to find that you have no Hot Water. That’s why we’ve come up with the initiative of connecting a temporary unit for you until we’re able to get your system completely fixed.

Most of the time, systems can be quickly fixed. However, there are times when particular parts need to be ordered, or replacement systems are low on stock. Whatever the case may be, you won’t have to worry because your hot water will still be running using our portable unit.

Our commitment is to get your system repaired and properly fixed without using band-aid solutions.

Installation & Replacement

When deciding on a new system to install, there are a few things to consider.

First is the size of your home and the number of people living there. This information helps you determine the size of the unit needed.

Location is another factor. If you’re going with a more extensive system, choose an area that won’t be an eye-sore with a bit of clearance around the unit.

Budget is the last main deciding factor. There are less energy-efficient units that will cost your more in the long run, so maybe an option is to upgrade to a more energy-efficient unit if you’re planning on living there long-term.

Continuous Flow Hot Water - B-Range

Rinnai Continuous Flow hot water systems are the most technologically advanced hot water system available today. These units are designed to be energy efficient by heating water as it passes through the unit, reducing running costs and greenhouse gas emissions.

Add to this its compact size, which allows it to be installed almost anywhere. The range is available in 16L (6.1 star), 20L (6.0 star) or 26L (6.0 star) variants and supplied in a neutral Dune colour.

Continuous Flow Hot Water – Infinity

Rinnai revolutionised the Australian hot water market in the early 1990’s when they launched the first electronically controlled gas continuous flow hot water system.

Appropriately named, the Rinnai Infinity delivered a new user experience of steady and continuous, temperature controlled hot water.

The latest Infinity products offer you unparalleled performance, user comfort, energy efficiency and water conservation features to help further reduce your household running cost.

Rinnai Continuous Flow hot water products have also been designed and engineered to withstand harsh Australian conditions whilst never running out of hot water.

This, coupled with excellent reliability, makes the Rinnai Infinity the obvious choice for your hot water needs.

Gas Hot Water Storage

Designed to be a quick, easy and cost-effective replacement for your existing 3 or 4 star gas storage system, the Rinnai Hotflo range offers you a choice of 135 or 170 litre storage capacities and delivers mains pressure hot water to multiple taps at once.

Rinnai has optimised gas consumption to reduce energy usage without compromising on performance.

This allows for sufficient first hour delivery and recovery capability whilst maintaining the life expectancy of the water heater.

Electric Hot Water Storage

Rinnai's hardworking range of Hotflo Electric hot water storage systems provides various features such as flexible installation options, Vitreous Enamel lined tanks and a generous 10-year warranty.

Rinnai Hotflo Electric storage systems are available in various capacities.

From the super compact 25 litre unit to the super sized 400 litre storage cylinder, these tanks are perfect for replacing an existing unit.

What Customers are Saying

“We had 2 split systems installed just over 2 years ago and have since had 2 service calls. We could not be happier with the service we have received from Plum. The servicemen have gone about their work with little fuss, explaining what they were doing and cleaning up after each unit was serviced. This morning Shiva was here, and he was very courteous as he was working. We have nothing but praise for Plum”

"Helpful and friendly team. We had to change the date and time of the install last minute and were greeted with a ‘no problems and happy to fit in with you’ attitude. The installers arrived on time. They were friendly and respectful. They were in and then out in no time and cleaned up after themselves. They even returned things they had moved back to their original spot. Very happy we went with Plum"
