        Wilson Elements | Bolt-On Hot Water Element 3600W | Dur-alloy Sheath

        The Wilson Elements HWDS-36 is a 3600W bolt-on hot water element with a dur-alloy sheath, made to replace a failed element in an electric storage water heater. At 240V the HWDS-36 draws around 15 amps, so the circuit feeding the tank needs 20A protection. Dur-alloy is the standard sheath material fitted to Australian residential tanks running on treated town water.

        A blown element means no hot water, and the call usually lands the same morning the shower runs cold. Diagnosis is quick: an open-circuit reading across the terminals, or a breaker that trips the moment the hot water circuit is energised. What holds the job up is having the right wattage and sheath material on the truck, because a mismatched element cuts recovery speed or fails early. The HWDS-36 covers the 3600W replacement slot that suits tanks of 160 litres and above.

        Element swaps are predictable work with a short parts list, so stocking the common wattages keeps a service call to one visit instead of two. Dur-alloy sits at the lower cost end of the sheath range and is the material most tanks left the factory with, which makes it the straight like-for-like choice on town water. On tanks past eight years old, ordering a thermostat at the same time avoids a second callback inside the same service year.

        Features

        • 3600W output — draws around 15 amps at 240V, so the HWDS-36 requires a dedicated 20A circuit rather than a shared 10A run.
        • Dur-alloy sheath — copper-based sheath with good thermal conductivity, specified for treated town water supplies.
        • Bolt-on mounting — bolts to the tank flange against a seal, so the HWDS-36 does not interchange with screw-in BSP boss elements.
        • 8NM torque ceiling — tightening the bolts past 8NM distorts the seal and causes a leak, so the bolts must be pulled up in the correct order.
        • Tank size match — 3600W suits storage tanks of 160 litres and above, where recovery speed matters after a heavy draw-off.
        • Faster recovery — higher wattage reheats the tank quicker than a 1.8kW element, at the cost of higher instantaneous current draw.
        • Off-peak compatible — works on controlled load and off-peak tariff tanks as well as continuous supply installations.
        • Treated town water only — copper-based sheaths corrode faster in bore water and high-mineral supplies, which shortens element life.
        • Licensed electrical work — replacement falls under AS/NZS 3000:2018, so the circuit must be isolated, locked out and tested dead first.
        • Dry firing risk — the tank must be completely full before power is restored, because an unsubmerged element burns out within seconds.
        • Package weight 0.342kg — light enough to carry several wattages in the van without eating into payload.
        • One-year warranty — one year domestic and one year commercial from the invoice date, handled by return to Sparky Direct.

        Where to use

        • Residential storage tank repairs — the HWDS-36 replaces a failed 3600W element in single-phase electric tanks of 160 litres and above.
        • Off-peak and controlled load tanks — suits tanks reheated overnight on a separate tariff circuit, where recovery time is set by element wattage.
        • Like-for-like data plate matches — fitted where the tank data plate calls for 3600W at 240V and the existing element is bolt-on.
        • Treated town water areas — metropolitan and reticulated supplies where a copper-based sheath gives acceptable service life.
        • Rental and managed properties — the HWDS-36 is a low-cost part for maintenance work where hot water outages need same-day repair.
        • Commercial tanks on single-phase supply — cafes, small kitchens and amenities blocks running standard storage units rather than three-phase plant.
        • Service van stock — held alongside other common wattages so a diagnosed element fault is repaired on the first visit.

        The HWDS-36 is not specified for bore water or high-mineral supplies, where a copper-based sheath corrodes well before the end of its expected life. It is a bolt-on element and will not fit tanks with a screw-in BSP boss. Do not fit it to 415V three-phase circuits or energise it before the tank is completely full.

        Verified Sparky Direct customer reviews: Hotwater Element Duraloy 3600W (HWDS-36)

        "What can I say this product is Hot Hot Hot" — Wayne

        "GREAT COMPANY TO DEAL, WITH GREAT PRODUCTS" — Emos

        (HWDS-36)

        Element replacement is licensed electrical work under AS/NZS 3000:2018 in every Australian state and territory. The hot water circuit must be isolated, locked out and tested dead before the element leads are disconnected.

        A 3600W element draws around 15 amps at 240V, so a dedicated 20A circuit is required. Confirm the supply voltage and the wattage stamped on the tank data plate before fitting, because a 415V element on a 240V supply gives severely reduced output.

        Fitment depends on mounting type, immersion length, wattage and voltage matching the original element. The HWDS-36 is a bolt-on element and does not interchange with screw-in BSP boss elements. Check the old element and the tank data plate before ordering.

        Dur-alloy copper sheaths suit treated town water and are what most Australian tanks were supplied with. In bore water or high-mineral supplies, copper corrodes faster, and an incoloy sheath holds up considerably longer under those conditions.

        Do not exceed 8NM. Tightening past 8NM distorts the tank seal and causes a leak. Pull the bolts up in the order shown in the fitting instructions supplied with the element, then refill the tank and check for leaks before restoring power.

        Energising an element that is not fully submerged causes dry firing, which burns out the resistance wire within seconds. Open the nearest hot tap while refilling and wait for steady water flow before switching the circuit back on.

        One year for domestic use and one year for commercial use, starting from the invoice date. Claims are handled by return to Sparky Direct. Warranty is void where the element was not installed by a licensed electrician.
