Selecting a Suitable Hot Water System
There are two main types of water heaters: Storage and Instantaneous (Continuous Flow). Instantaneous heaters heat the water instantly and provide continuous flow around the clock, while in storage heaters, water is heated at particular time of the day mainly during off peak and stored in a tank.
Supplied and installed Hot Water Systems start from $599.

Hot Water - Ruptured & Leaking Tank
A hot water tank will usually last about 6 - 10 years before it decides to rupture or leak. The main cause is that the cylinder walls have corroded from rust.
Ask us about rust protection by replacing the sacrificial anode. They can also rupture due to a faulty safety valve. We can check your valve FREE of charge.
If your tank has sprung a leak you will need to turn off the water pressure quickly to prevent water damage to your property.
The main shut off valve for your hot water tank is usually found at the bottom left or right side of your Tank.
It will either be a black round knob or a tap handle similar to your garden tap handle.
To turn this valve off simply turn it in a clockwise direction until the water stops flowing.
Next release any pressure remaining in the tank by activating the Safety Valve located near the top side of your tank.
The Preventative Maintenance is very crucial to the health and life of your hot water system
How Can You Make The Hot Water Unit Last Longer?
Every Enamel (glass) lined mains pressure hot water tank is fitted with either one or two Sacrificial Anodes, which protect the tank from corrosion.
Unfortunately sacrificial anodes do not last much longer than the standard warranty period of the tank, which is 5 years.
We recommend that they are checked and replaced every 3-4 years to ensure the maximum life of your tank. In addition we recommend that your tank should be drained and flushed every 5 years.
Why Replace The Anode?
The Anode is "sacrificial", meaning that it is a softer alloy than the cylinder and all corrosion will occur at the Anode and not your cylinder.
Seven Very Good Reasons Why You Should Replace Your Anode And Taper Valve Every 3-5 Years.
- Your hot water tank will last years longer.
- You will save money $$$ by making the tank last up to 3* times longer *(this will depend on water quality and regular servicing of your unit).
- You will save on the inconvenience and the hassle of frequent hot water replacements.
- You will save $$$ on electricity or gas when your tank is operating correctly.
- You will be helping the environment, (less tank replacements, less disposal at our ever diminishing rubbish dumps).
- You will not be wasting valuable resources (electricity, gas & water).
- Your hot water will be much cleaner for showers, dish washing and the laundry.

Thermostat/over Temperature Cut Out Device
This is a very important device, as it controls the temperature (60 – 70C) and will also cut off the electricity supply to the element through its over–temperature cut out, if it senses a very high (90c) temperature.
The thermostat labours hard, switching on and off thousands of times over a few years, and needs to be checked for performance at least every 5 years.
Imagine the scenario. The Thermostat has failed, your tank is reaching boiling point, and the Temperature Relief Valve is not functioning!!! Please get it checked.
GAS Hot Water units also have a THERMOSTAT, but it's a bit more high tech than its electrical cousin. Mainly because it's controlling the temperature, as well as the gas flow, and will also shut itself down if there is an over temperature or gas flow problem; this device also works extremely hard over the years.
Going On Holidays Tips
If you look closely at the large black dial, on top of your gas Unitrol valve, it is numbered 1 to 7. If you turn the dial to 1 this is the "vacation" point, the pilot light will stay on but the main burner will not fire up. When you return from holidays you just simply turn the dial to between 5 & 7, the burner will fire up & you should have hot water in about 1 hour.
If you’re Gas Hot Water Unit Pilot Flame goes out! There are relighting instructions on the inside lid of your tank, or for indoor models on the tank itself. If you have any difficulty at all, please call our office and one of our staff will be glad to give you all the instructions to get you going; and if all else fails we will make arrangements to have one of our servicemen come out within 24hrs.
Common Issues with hot water systems
The types of issues that your hot water system may have will depend on the type that you have.
- Dirty water: The water may come out brown or rust-coloured. This is often caused by a rusted tank. Another element of the water heater may have broken and corroded inside of the tank as well.
- No hot water: If the water does not heat at all, this may signal a defect with the wiring or heating mechanism. If the water heater is powered by gas, the pilot light may be out or the control valve may need to be replaced.
- Not enough hot water: Your water heater may be too small for your needs. If this is not the case, the water heater may not be receiving enough power to the heating element.
- Water heater makes noise: This is most likely due to a build-up of sediment inside
