Hot water System Repairs and Servicing


When it comes to servicing your hot water system, the different types of hot water systems have different time frames for service intervals in order to ensure you are getting the most out of your heater system. Having your hot water system services about every 2 years will ensure you have an energy-efficient tank reducing the household energy use and saving you on energy costs. so, in turn, you will save money on your electricity bill, which only seems to be on the rise.


To understand the lifespan of a hot water system, we have put together an approximate time for you on the common types of systems we install in Sydney. There are a few hot water system options so, here is the general rule you can follow for the water heater systems you have:


  • Electric hot water system - 8-12 Years
  • Gas hot water system - 10-12 Years
  • Heat Pump hot water system - 10+ Years
  • Solar hot water systems - 15-20 Years


The above life span of a hot water heater is based on the fact that they are services roughly every 2 years. Servicing your system will allow the licensed plumber to make sure your hot water system is in good working order and is operating to its full capacity. There are parts to a Hot Water heater that will be repairs or replacing before you will be in need of a new hot water system.


These parts include the sacrificial anode, temperature & pressure relief (TPR) valve, tempering valve, test ignition point and pilot light. These items will be routinely checked and replaced as needed by a hot water repair specialist.

  • Are Hot Water Repairs Expensive?

    This will vary depending on what part of your electric, solar, heat pump or gas unit needs repairing or replacing. There are many factors that make up hot water heaters, including a heating element, sacrificial anode, pilot lights on gas hot water tanks, tempering valve, TMV, and the hot water tanks themselves.


    If you think you are in need of hot water system repairs, in need of a new hot water tank or just want to talk to someone about electric hot water systems vs gas hot water systems, then give us a call! Your hot water unit is safe in our hands.

  • My Electric Water System Is Making A Strange Noise, Is That Normal?

    No, it's not normal for electric hot water systems to make unusual noises... If you hear a strange noise coming from your hot water tank, that is a good suggestion that there is something wrong and you need to call a licensed plumber ASAP to look at the electric hot water systems as you will most likely need hot water repairs. A licensed plumber should be the only person to carry out a hot water system repair for you, otherwise, you will be at risk of voiding any warranty you may have on your hot water heaters.

  • I Only Have Warm Water... Do I Need A Hot Water Replacement?

    Not necessarily. You may only need a service or parts replaced, depending on the age of the system. Warm or cold water is certainly one of the signs that something might be going on inside the tank and it needs to be looked at by a professional service.


    Our professional plumbers always do an amazing job when it comes to identifying the cause of the plumbing issues. Our service vehicles are well stocked in order to accommodate all plumbing emergency needs so that Sydney residents will have their hot water running efficiently in no time.

Do Hot Water Systems need maintenance?


Hot water systems are one of those things that we use day in, day out, yet we don't think to show them a little TLC until the day we wake up and there is no hot water, or they go BANG!


Your Hot water system services the whole house, from the bath & shower to all the taps in your home or workplace, as well as appliances that require the use of hot water. So, when you think about it, hot water systems may just be the hardest working appliance we have.


Just like the car that we service annually to make sure we can get from A to B without issues, hot water systems need to be serviced around every 2 years (depending on the types of hot water systems you have). A hot water specialist is the only person that should be carrying out an existing hot water system service or hot water system repairs.


If you have noticed any issues with water temperature, leaking hot water systems, hot water taps not heating to their usual temperature, or have no hot water at all, then it's best that you give us a call and we can send one of our hot water specialists to investigate the issue for you. Whether you have an electric hot water heater, a solar hot water system, a gas hot water system or have heat pump hot water, our professional plumber can identify what needs fixing and can have your hot water up and running in no time.

Hot Water Systems


Help choosing which Hot Water System is best for you


Choosing which Hot Water System is best for your house can seem a daunting process as there are so many hot water system types on the market. The type you have might also depend on how much hot water you need on a day to day basis. Chiswick Plumbing is able to assess your property and household needs to make recommendations on the best hot water system for you and provide detailed quotes.


Below is a sample of the various gas, electric and solar hot water systems available in Australia...


Gas Hot Water Systems

If you have a connection, Natural gas is a good option. It can be cheaper than electricity; gas rates don’t vary through the day and gas hot water systems can heat water as needed. A four-person household may require a 135–170L tank. You also have the option of an instantaneous system.


Due to venting requirements, Gas systems are usually installed outdoors, however, they can be installed indoors with a flue.Gas has an energy efficiency star rating. Some have a pilot light, which uses a small amount of gas.


Electric ignition is more economical, but in a blackout you can lose your hot water supply.

Liquid petroleum gas (LPG) bottles are an alternative to natural gas – however, this will increase your running costs.

5 Star Gas Storage

Perfect for anyone looking to convert from an old electric water heater, 5 star gas storage water heaters are better for the environment and cost less to run.


Important:  Depending on the tank material, 5 star gas storage systems require routine sacrificial anode replacement to prevent corrosion and prolong the lifespan of the water heater.


Chiswick Plumbing install 5 Star Gas storage water heaters, such as:

Dux Prodigy 5 Range

  • New burner technology – faster recovery rates, more hot water
  • Identical footprint with existing 3 star gas storage unit, ensuring easy replacement

  • Patented flue damper design reduces heat loss
  • Full flow mains pressure delivery
  • 5.3 Star energy efficiency rating
  • 10 year tank and flue warranty, 1 year full parts and labour


Rheem Stellar Range

It’s a revolution in high performance water heating with a sleek ultra modern styling! The Rheem Stellar has a first hour capacity of up to 360 litres followed by 200 litres of hot water every hour – much more than most households will ever need.


  • 130 litre and 160 litre Vitreous Enamel models available
  • 5 Star energy efficient
  • Mains pressure to power many taps at once
  • Big enough for the largest family
  • 10 Year cylinder warranty for complete peace of mind
AquaMax Gas Range

  • 130 to 155 Litre Stainless Steel tank
  • 5 Star Energy Rating

4 Star Gas Storage Hot Water System

Important:  Depending on the tank material, 4 star gas storage systems require routine sacrificial anode replacement to prevent corrosion and prolong the lifespan of the water heater.

Dux Prodigy 4 Range

  • Leading technology – in first hour capacity and recovery rates
  • Now matches the first hour capacity of the old 3 star models
  • New burner technology – faster recovery rates, more hot water
  • Identical footprint with existing 3 star gas storage unit, ensuring easy replacement
  • Full flow mains pressure delivery
  • 7 year tank and flue warranty, 1 year full parts and labour


Rheem 4 Star Gas Range

Reduce your gas bills and your carbon footprint at the same time with Rheem’s 4 Star 90L to 170L gas water heater. It’s an easy and more energy efficient replacement for most older gas water heaters.


  • First hour capacity between 190L to 283L

Continuous Flow

Hot Water Systems

Instantaneous/Continuous Flow

A tankless system that delivers continuous Hot Water.  Entering cold water passes through a heat exchanger (usually located outside) to instantly deliver hot water to your various taps and fixtures.


Continuous or AKA Instantaneous Hot Water Systems, heat only as much water as you need, when you need it. Depending on the distance between your tap and the Hot Water System, it may take a few seconds before hot water begins to flow. Most models use gas, but electric models are available.


The size you need (flow rate in litres per minute) depends more on the number of hot water outlets the heater has to serve, than on the number of people in the household. As a general rule, for a two-bathroom house you need a flow rate of about 22–24 L/min. Talk to your Chiswick Plumbing to find the right capacity for your home.

Electric Storage Hot Water Systems

An electrically heated storage tank system is usually relatively cheap to buy and install, but is usually the most expensive to run, especially if it’s on the continuous (full day) rate.

Systems that run on off-peak electricity are much cheaper to run, but need a larger tank as the water heated overnight has to last you all day. And off-peak electricity isn’t available to all homes. A four-person household typically needs a 125–160L tank for a continuous system or 250–315L for off-peak. Can be installed indoors or outdoors.

Ground/Roof Mounted Solar Hot Water Systems


Solar Water Systems or Solar Domestic Hot Water Systems can be a cost-effective way to generate hot water for your home, using a FREE fuel – our sunshine!


Solar Water Heating Systems use Solar Panels (or Collectors), which are typically mounted on the north facing aspect of a roof, to capture the heat and light from the sun. Water is drawn into the Panels from a Storage Tank which is either located on the roof or at ground level. The heated water travels from the bottom of the Panel to the top, where it is then returned to the tank.

1

Dux Sunpro Range

The Dux Sunpro is a ground mounted, split solar system (tank on ground, solar collector panels on roof) and comes in Gas & Electric boosted models.


  • Mains pressure hot water unlike continuous flow boosted systems
  • Low megajoule consumption burner
  • Patented Panel Management System protects against overheating in summer & frost damage in winter
  • Fully compliant to the new solar legislation

2

Rheem Loline Range

The Rheem Loline® is a ground mounted, split solar system (tank on ground, solar collector panels on roof) and comes in Gas & Electric boosted models. Do your bit for the planet and save energy at the same time! Go solar with the Rheem Loline® solar hot water heater. It’s designed for warmer climates and areas with good water quality.


If you need an emergency replacement, you can run this water heater on its electric boost until your panels are installed.

3

Rheem Hiline Range

The Rheem Hiline® solar hot water heater is ideal for warmer climates and areas with good water quality. It’s a great option when ground access is limited as the storage tank and solar panels are mounted together on the roof. The Rheem Premier Hiline® solar water heater is ideal for cooler climates, prone to frost with good water quality.

4

Rinnai Sunmaster Range

The Rinnai Sunmaster solar range is designed to maximise the free energy from the sun, whilst also providing quality units that are affordable. Environmentally friendly and cost effective, Rinnai have developed 3 types of solar hot water units, close coupled systems, flat plate systems and evacuated tube systems, which allow their solar water heaters to be integrated into almost any home.

Split/Integrated Heat Pumps -

Pump Hot Water Systems

Instead of generating heat directly, Heat Pump Hot Water Heaters use electricity to move heat from the air and transfer it to heat your water, the reverse of a refrigerator! They are up to three times more efficient than conventional electric water heaters. When used in the right climate conditions they save energy, save money and reduce greenhouse gas emissions. You can purchase stand-alone heat pump hot water systems as an integrated unit with a built-in water storage tank and back-up resistance heating elements. You can also retrofit heat pumps to work with an existing storage water heater.


Dux Airoheat
  • An easy one piece, compact design makes for a quick and simple installation
  • Airoheat now includes an innovative de-icing function so there’s no need for a back-up element
  • Management by the innovative Hotlogic® controller allows the Airoheat to keep running in cold climates

  • Same fittings as an electric water heater
  • No solar panels required
  • Relatively low cost to purchase and install
