What is Dur-alloy?
Using a specially processed High Grade stainless alloy, the Dur-alloy elements approach incaloy corrosion resistance for roughly the same price as copper.
Why Dur-alloy?
Dissolved minerals (such as salt, calcium & lime) in the water supply can result in scale (like that found in a well used kettle which sometimes comes losse and ends up in your coffee) building up on a water heating element. Where these concentrations are high, this will considerably shorten the life of the element. Traditionally, elements utilising expensive stainless steel alloys such as incaloy (800 & 825) that are resistant to this scale build are used to extend element life in hard water areas but these are becoming less popular due to their higher prices.
Increased durability in soft water markets & suitable for higher hardness mains supplies in regional cities. (Sydney, Canberra, Hobart, Melbourne, Brisbane, Adelaide & Perth)
Recovery time depends mainly on the kilowatt rating rather than the alloy, but a reliable element helps maintain consistent performance.
You can find Hot Water Dur-Alloy Elements through Sparky Direct, offering Australia-wide delivery and access to trade-trusted electrical products.
Returns depend on the supplier’s policy and whether the product is unused and in original condition.
Most reputable brands offer a manufacturer’s warranty, with terms depending on the product and usage conditions.
Some are supplied with basic seals, but this varies by manufacturer and should be confirmed before purchase.
You should match the element’s kilowatt rating, flange type, and length to your hot water system’s specifications.
Installation or replacement should always be carried out by a licensed electrician or plumber, depending on the system requirements.
Yes, they are designed for use in domestic hot water systems supplying potable water.
Energy efficiency is primarily determined by system design and insulation, but a properly functioning element supports efficient operation.
Yes, when correctly sized, they are suitable for families and high-demand applications.
No, they operate silently, like other electric hot water elements.
While it does not control water quality, its corrosion resistance can reduce issues linked to element degradation.
They can reduce the frequency of element replacement, but regular system servicing is still recommended.
Dur-Alloy elements are electric hot water heating elements made from a corrosion-resistant alloy designed to heat water efficiently while withstanding harsh water conditions.
Yes, they are often chosen in hard-water regions because they cope better with mineral buildup.
Dur-Alloy elements offer better resistance to corrosion and scale, which can mean fewer failures and more consistent hot water.
Yes, installation or replacement of hot water elements must be carried out by a licensed electrician or plumber in accordance with Australian regulations.
Dur-Alloy elements are designed for storage-type electric hot water systems, not gas or electric continuous flow units.
While no element is completely scale-proof, Dur-Alloy materials can be more resistant to damage caused by scale compared to standard elements.
Yes, Dur-Alloy elements are often suitable for stainless steel tanks, provided they are approved by the tank manufacturer and correctly matched.
Most electric storage hot water systems can use Dur-Alloy elements, but compatibility should always be confirmed against the tank manufacturer’s specifications.
They are available in various lengths and wattages to suit different storage tank sizes and heating requirements, typically ranging from lower wattage domestic units to higher output options.
Quality Dur-Alloy elements are manufactured to meet relevant AS/NZS requirements for electric water heating components when installed correctly.
Yes, Dur-Alloy elements are commonly used across Australia and are designed to handle a wide range of local water qualities, including mineral-heavy supplies.
Dur-Alloy offers improved resistance to corrosion and scaling, making it suitable for areas with hard or aggressive water where copper elements may fail prematurely.
