WHAT ARE THE DIFFERENCES BETWEEN RESISTIVE ELEMENTS AND THE NEW XTEND ELEMENTS?

  1. Xtend Elements have internal temperatures at 270°C vs the 500°C of standard resistive elements, meaning this element is better suited for hard water areas (this is due to the higher temperatures causing more solids to accumulate on the element, causing inefficiency and ultimately failure in resistive elements).
  2. Due to the high temperatures of the standard resistive elements, they accelerate the turning of chlorine in water into a mild solution of Hydrochloric Acid which attacks the anode and thereafter the drum causing catastrophic failure.
  3. Xtend Elements are manufactured from 316 stainless steel, making them exceptionally durable and resistant to the effects of hard water.
  4. Xtend Elements have exceptionally low watt density resulting in the longer life of the element, making it less susceptible to overheating caused by scale build-up or sludge. This element will not fail due to scale build-up. They simply reduce power to a minimum operating level without overheating.
  5. Xtend Elements also use a thermostat (due to legislative requirements) but the element will, by design, automatically reduce power output as the resistance increases (as water warms up).
  6. Resistive elements are generally set to 60°C, PTC elements are set 10 degrees lower and give the same result.
  7. Resistive elements have zero capacity to function in air, they fail, usually tripping the electricity – a disaster if one is away.
  8. Xtend Elements are tested to 5,000 dry burn cycles which means they will not burn out if the geyser has no water in it.

HOW DO WE SAVE ENERGY WHILE HEATING WATER?

The Xtend Element draws full rated power upon start-up to quickly heat the water and reduces power use as the operating temperature is reached.

THIS MEANS THE ELEMENT ONLY WORKS AS HARD AS IT NEEDS TO, TO REACH OPTIMAL WATER TEMPERATURE.

Think of it like a car – with a resistive element you’re either flooring the throttle or taking your foot off the pedal completely a thousand times a minute – which is totally energy inefficient.

The Xtend Element goes full throttle to start and then gradually takes its foot off the pedal, as temperature increases. To maintain speed (temperature) it just needs a touch of acceleration every now and again – which is more efficient.

The element only works as hard as it has to in order to maintain temperature, saving energy and achieving more consistent temperature control of the geyser. In other words, our Xtend Elements have a faster heating rate on minimum resistance (when the water is cold) and as the water temperature rises the element reduces power. This setting, known as the Curie Point, is built into the ceramic element construction.

WHAT IS PTC?

Positive Temperature Coefficient. A PTC element’s electrical resistance rises as the temperature increases. This means that the resistance is very high at the design set-point (Curie point), so electricity cannot flow through the element, and it stops heating any further. The element is self-regulating, so no external thermostat is required.
