Water quality has a major impact on hot water systems. Issues like hard water can cause scale buildup, corrosion and sediment, reducing system efficiency. Regular servicing and maintenance is required to optimise performance, energy efficiency and longevity of your hot water system.
The performance and lifespan of hot water systems are highly impacted by water quality. Hard water, containing minerals such as calcium and magnesium, can create scale, leading to corrosion. Additionally, sediment, bacteria, and incorrect temperature settings present further challenges.
In Cherrybrook, Sydney, homes typically receive safe drinking water through a combination of rainwater tanks and the local water authority’s tap water supply. Water composition for drinking can vary based on your location. Despite Sydney’s generally soft water, factors still exist that can influence your hot water system.
This guide examines the effects of water quality on heaters and offers preventative measures to maintain efficiency and avoid expensive repairs.
Understanding the influence of hard water, which contains high levels of calcium and magnesium, is crucial for effective water heater maintenance. Dissolved calcium and magnesium in hard water can crystallise as scale, leaving behind sediment in your system. Over time, scale buildup, which water hardness directly affects, reduces the efficiency and lifespan of heaters.
In Sydney, the local water source often provides households with moderately hard water. Scale tends to accumulate in water pipes, tanks, heating elements, and valves, posing issues.
The mineral content isn’t extreme, but it’s still enough to cause problems if left unchecked. This can reduce water efficiency, waste energy, and potentially lead to overheating and failure in your water drinking system.
Scale provides a breeding ground for bacteria. Cloudy or foul-smelling hot water suggests bacterial contamination in mineral deposits. Flushing your water heater tank annually with aerated water is a good practice to help control bacteria.
Galvanic corrosion is accelerated by hard water, particularly within iron pipes and galvanised components. When minerals deposit on metal components, it accelerates corrosion between incompatible metals, like new copper and steel. Use lead-free plumbing materials to prevent rapid anode rod deterioration and tank leaks caused by hard water.
To reduce the impact of hard water, you can install a water softener or scale inhibitor. Maintenance is key as well, like draining and descaling your heater every 1-3 years. If problems persist, don’t hesitate to call us; our expert team can assess your water and recommend the best solutions.
Scale accumulation is a frequent issue in hot water systems due to hard water. As water cold is heated, minerals like calcium magnesium, and others become less dense and less soluble. These minerals, being dense than the water, then precipitate, clinging to interior surfaces of your storage tank, potentially impacting your drinking water quality.
Scale deposits reduce heat transfer efficiency, impede water flow, and increase operating costs. They also provide an environment for bacteria to thrive.
To prevent scale buildup, we first need to understand the hardness level of your home’s incoming water supply. Water is generally classed as hard if it exceeds 120ppm and soft if below 60ppm. Water that is both hard and heated to higher temperatures is typically more susceptible to scaling.
A water softener or electronic descaler installation can mitigate scale formation. We recommend draining your water heater annually, using quality plumbing products, and inspecting for any scale deposits. If you see white or yellowish mineral buildup, descaling may be needed to restore efficiency.
With the aid of advanced test kits, our licenced plumbers can test your water quality, advise on the best heat pump options, and perform maintenance to optimise your premise plumbing. Don’t let scale go unchecked - proper maintenance keeps your heater working efficiently for years to come.
Hard water typically results in lower efficiency and a shorter lifespan for your water distribution system. Accumulating scale deposits form an insulating barrier which hinders heat transfer and increases energy consumption. Lack of energy efficiency means more energy is required to heat the water to the desired warm water temperatures, driving up energy bills.
Scale also gradually reduces water pressure, restricting flow through your household plumbing system, including pipes and valves. This added backpressure forces the heater to work harder, undermining the continuous flow of water, again wasting energy. Flow restrictions can impact your system’s performance and lead to temperature fluctuations and even dead spots with lukewarm water.
In addition, scale compromises the quality of household water by providing an ideal environment for corrosion and bacteria. Anodic corrosion is expedited, as metals can deteriorate the tanks from the inside. Leaks, cracks and potential tank failure become increasingly likely over time.
Decreased efficiency and capacity can cause commercial heaters to have a shorter operational lifespan. Businesses experience disrupted hot water supply and higher costs. In systems can serve large buildings, small efficiency losses can multiply, leading to significant costs.
Water softeners or electronic descalers can help maximise the longevity of your system. Annual flushing and draining to remove mineral deposits is also crucial to extend its lifespan. This keeps your hot water system running efficiently for longer, with fewer repairs needed down the road.
Substandard water quality may facilitate bacterial and biofilm proliferation in hot water systems, leading to unpleasant smells, cloudiness, and health concerns. Hard water provides an ideal setting for bacteria to thrive, impacting all life, which may raise concerns about environmental health as the scale deposits give them abundant surface area and nutrients.
The safety of water quality, particularly in controlling bacteria, is highly dependent on maintaining appropriate temperatures.
Storage tanks and low-flow areas are susceptible to increased bacterial levels. Thermostats and tempering valves should be set correctly to ensure hot water temperatures stay above 60C throughout the system.
To control bacteria, proper maintenance is crucial. Inspecting for slime or smell is important too. This removes sediment so bacteria have less to feed on. If you notice rotten egg odours, a matter that has entered the public domain, it could signify sulphurous bacteria.
It’s advisable to annually flush your heating system by draining several buckets of water from the valve.
Sanitising your hot water system every 3-5 years helps kill bacteria and maintain quality. Technicians leverage treatment methods akin to those used in cooling towers to cleanse your entire hot water system. We can also test your water and advise on permanent disinfection systems using UV light or ozone generators if bacteria regrowth is an ongoing issue.
Dont ignore strange smells or dirty water coming from your tap. Contact our Cherrybrook plumbers for professional maintenance tailored to maximise the efficiency and safety of the water your household uses. With the right care, your hot water system can deliver quality water for years to come.
As water flows through pipes and fixtures, sediment gets stirred up and carried along. Suspended particles that settle in the tank could affect water quality for consumption and everyday use.
More energy is required to heat water properly.
Furthermore, changes in water chemistry can supply nutrients and surface area that allow harmful bacteria to prosper. A sediment layer acts as insulation, which compromises heat transfer efficiency.
To prevent sediment buildup in cold water taps as well as hot, flush your system annually by draining out a few buckets from the tank drain valve. If you notice cloudy water with air bubbles or discolouration from hot taps, a full flush out and inspection may be required.
This removes debris before it accumulates. We can drain, de-scale and sanitise your hot water system to restore performance.
Sediment filters at point-of-entry locations can also be installed to trap debris before it enters the water heater. These filters require regular cleaning or replacement to remain effective. Contact our team - we can advise on the best sediment filtration options for your home or business.
With proper maintenance to control sediment, your hot water heater will run more efficiently for longer. Keep an eye out for warning signs of buildup, making your water more susceptible to issues, and contact our licenced plumbers if you need a system inspection or flush out.
These particles settle within your hot water system, affecting its function.
Yellow, brown, or rust-colnfectant in the water supply.
Rotten egg or sulphur smells signify bacteria growth.
If your hot water appears dirty or smells bad, start by having your water tested. In severe cases, a full descaling and sanitising of the system may be needed.
We can check what’s happening inside your water heater, including sediment levels, harness, bacterial contamination, and more. Flushing the water heater can help remove any debris or scale buildup.
Ongoing issues with discoloured or smelly water require preventative maintenance. Installing water filters, sediment filters, water softeners or electronic descalers reduces contaminants. Annual draining and inspection of your hot water system also helps prevent sedimental and bacterial issues before they escalate.
Don’t ignore warning signs of poor water quality. Contact our team - we can troubleshoot the issue and recommend solutions to restore clean, safe hot water.
Discoloured or smelly water from your hot taps is often a sign of suboptimal water quality affecting your hot water system.
A strong chlorine odour can mean excess disinfectant, suggesting the water might contain higher levels of chlorine than usual.
Corrosion and rusting are common issues that can impact water heaters, partiwo dissimilar metals react together in water. Mineral deposits left by hard water create localised corrosion sites.
Rust flakes then contaminate the water supply.
Water pH, which can alter including that used for drinking, is a crucial factor influencing corrosion rates. Acidic water is more aggressive at corroding parts like storage tanks and pipes. The presence and amount of dissolved oxygen, which is used in drinking water production, oxygen do indeed influence and can expedite corrosion processes.
To reduce corrosion, maintain your water heater by flushing it annually. This removes scale deposits and prevents pitting. To reduce corrosion, maintain your water heater by flushing it annually. A corrosion inhibitor or alkaline water treatment may be recommended in some cases.

Proper temperature regulation is essential for limiting bacterial proliferation in water heaters.
Common pathogens like Legionella multiply rapidly at temperatures warmer than 20-50C.
Ideally, your thermostat should maintain a consistent temperature range, set to deliver hot water above 50C to all fixtures. For systems with recirculation, maintaining temperatures above below critical levels is essential, to adhere to optimal temperature patterns. Tempering valves can be installed to reduce scalding risks at points of use.
Annual inspections of your hot water system can identify any low temperature areas prone to bacterial growth. Flushing the tank and running hot water through all taps helps prevent pathogens from taking hold, especially when water sits stagnant. If bacterial counts are high, professional disinfection of the heater and plumbing may be advised.
Optimal temperature settings and preventative maintenance can mitigate effects on your system from water source variations, including surface water contamination. This maintains water quality, like a pristine lake can, and reduces potential health risks like Legionella.
