Instant Hot Water Systems Sydney
While most homes rely on storage tanks for their hot water, there is now a more efficient and cost-effective solution on the market called an Instant Hot Water System.
An instant hot water system involves no tank and simply warms water as and when you need it. Most systems can handle upwards of 10-30 litres of water per minute making them suitable for all household purposes including showering, doing the dishes, and filling a bathtub.
Most systems work by allowing heat to pass from a submerged heat exchanger to a steady supply of water before reaching your tap. This means only a small amount of water at any one time is being heated rather than needing to heat an entire tank of water.
The result is instant, on-demand hot water that does not run out. Even in large homes or commercial properties, the use of multiple instant hot water systems can eliminate the need for a water tank and can save a considerable amount of money in the long run by only heating and using water as and when you need it

Why people are switching to an instant hot water system
There are four distinct advantages to choosing an instant hot water system and replacing your traditional water storage tank:
What to consider when choosing an instant hot water system
While instant hot water systems are an ideal replacement for water tanks, there are some considerations you need to bear in mind:
Different Models of instant hot water systems have varying flow rates. This refers to the rate of hot water that the unit can output, typically measured in litres per minute.
Most instant hot water systems can output at least 10 litres of hot water a minute. While this is suitable for single-person or low-use households, busier homes or commercial properties will be better suited looking at higher-end models that can output upwards of 30 litres per minute.
Instant hot water systems are a lot smaller than traditional water tanks and so can be fitted in alternative locations.
If you’re interested in switching to an instant hot water system you should consider where you would like the unit to be situated. This will ideally be somewhere close to a gas or electric supply as well as an existing water source.
You should also consider what sort of energy you want to power your instant hot water system. While gas models are the most popular, electric models are available for properties without an available gas supply or want to take advantage of stored solar energy, for example.
Larger homes will likely need more than one unit or a higher-end model if intending to use multiple sources of hot water simultaneously.
The number of units you need depends on your expected demand for hot water and – if opting for an electric unit – the type of electricity supply in your home.
Most homes have a single-phase supply but some larger and commercial properties will have a 3-phase electricity supply. While a single-phase 13kw unit, for example, would likely be enough for a couple living alone, it would not be enough for some workplaces or households with multiple occupants.
MPJ Plumbing’s team of experts can help advise you on what solutions are available depending on your situation.
Common instant hot water system repair problems MPJ Plumbing tends to in Sydney
While most Sydney households enjoy soft water, some mineral buildup can still occur over a long enough period of time.
These mineral deposits can cause minor blockages within the hot water system and prevent hot water from reaching the tap or showerhead.
MPJ Plumbing recommends pre-emptively resolving problems and booking a professional flush and clean of your system every 12 months.
Instant hot water systems can also produce water that is too hot if the inlet filter is not regularly cleaned. MPJ Plumbing can perform this maintenance as part of a recommended routine service on your system.
Should you discover your instant hot water system has no pilot light, this could indicate disruption to your gas supply or an inadequate water flow.
If other gas appliances within your home work correctly, try turning the hot water tap at least halfway. If a moderate or high water flow still does not cause the pilot light to ignite, professional advice is recommended.
While a small amount of cold water is to be expected before hot water begins to flow, a cold blast in the middle of a shower could indicate other problems such as a failed part or inadequate flow rate.
Diagnosing the cause of these issues can be difficult. MPJ Plumbing can help you determine whether your tankless hot water system is broken or in need of an upgrade.
Gas-powered instant hot water systems need a supply of air for combustion as well as venting fumes. Some units will indicate this via a system message, others will simply cease to work correctly.
In either case, you should contact MPJ Plumbing to fix your system to ensure it is safe for you and others on your property.

Gas-powered instant hot was systems are typically more economic and have lower CO2 emissions if using a high-rated, energy-efficient model.
No. While many instant hot water systems use gas as a fuel source, these still require electricity to function. This is because the internal circuitry, ignition, and thermostat all require electricity to function.
In order to prevent problems from mineral buildup, MPJ Plumbing recommends booking a flush of your system once a year. This prevents corrosion within the instant hot water system that can occur even in soft water areas.
