Until recently consumers in South Africa had limited options when choosing an element for the geyser. Standard resistive elements are included and are either straight or spiral and use either a flange or screw in fitting. All use resistive wire to heat the water and are not as efficient as other forms of elements.
The main concerns with standard resistive elements is that they use considerable energy to heat water and are exposed to scaling. Over time the efficiency of the element drops because of this scaling and this causes the element to use more energy and potentially burn out.
XTEND elements are new to the market and have been approved by SABS and major geyser manufacturers. XTEND elements use ceramic chips to heat water instead of resistive wire, with greater efficiency. XTEND elements are also protected by a marine grade stainless steel outer casing which prevents scaling of the element. Our elements are warranted for 3 years and they will last longer than standard resistive elements, providing power for an expected 5-7 years. Finally XTEND elements can be used with solar PV systems which effectively heat the geyser for free during the day.
