A Smarter Way to Heat Water
An element heats the water inside your geyser. Standard elements use coiled resistance wire protected by a metal sheath. XTEND Elements are fundamentally different.
XTEND uses self-regulating PTC ceramic technology, protected by a durable marine-grade stainless steel or titanium casing.
This fundamental difference gives XTEND several advantages:
- Uses up to 25% less electricity
- Draws 1 kW less power while heating water at a similar rate
- Reduces limescale build-up, making it well suited to hard-water areas
- Reduces replacement and maintenance costs
- Works well with solar PV and battery systems due to its lower power draw
The basic design of conventional resistive geyser elements has changed very little in decades. XTEND uses modern PTC ceramic heating technology instead of traditional resistance wire.
PTC technology automatically adjusts its power draw according to operating conditions. Combined with XTEND's large surface area and low watt density, this provides efficient and effective heat transfer.
The result is simple: less power required to heat your water.
✔ Around 25% energy savings
✔ Lower power consumption
✔ Efficient heat transfer
✔ Modern PTC technology
Hard water causes limescale and other deposits to build up around geyser elements. Over time, this can reduce the performance of standard elements and eventually cause them to fail.
XTEND Elements are protected by a durable marine-grade stainless steel or titanium casing. As scale builds up, the self-regulating PTC heating core adjusts its power draw to protect itself from overheating.
If excessive scale eventually slows heating, the XTEND Element can be removed, cleaned and reinstalled.
XTEND is also protected against dry burnout. If a geyser empties, the PTC technology automatically limits the element's temperature and power draw.
XTEND Elements have been tested to more than 5,000 dry-burn cycles.
✔ Built for hard water
✔ Easy to clean and reuse
✔ Protected against overheating
✔ Protected against dry burnout
As electricity prices rise, more homes are turning to solar PV and inverter systems.
Reducing electricity consumption is often more cost-effective than installing additional solar panels and batteries. XTEND reduces the geyser's power demand, making it easier to include your geyser in your home's solar energy system.
Excess solar power generated during the day can be used to heat your geyser, effectively storing energy as hot water for use later.
Using a timer or smart geyser controller allows heating to be scheduled during peak solar production.
✔ Lower geyser power demand
✔ Easier load for your inverter
✔ More solar power available for your home
✔ Store excess solar energy as hot water
✔ Reduce reliance on grid electricity
Turn your geyser into a solar energy asset.
About XTEND
XTEND Elements was created with a simple goal: make geysers more efficient, reliable and affordable to operate.
Our team brings together experience in technology, finance, sales, business and domestic water-heating systems.
With electricity prices increasing and solar PV becoming more accessible, we saw an opportunity to rethink one of the biggest energy users in the home - the geyser.
XTEND reduces the energy and power demands of water heating while keeping the geyser system simple and low maintenance.
For homes with solar PV, the geyser can also become a valuable energy-storage asset - absorbing excess solar power during the day and storing that energy as hot water for later use.
By reducing the energy needed to heat water, XTEND can help lower electricity costs while reducing demand on South Africa's electricity infrastructure and the environment.
Simple. Efficient. Low Maintenance.
We are proudly South African and grateful for the support we have received from our customers, suppliers and partners.
If you're considering installing an XTEND Element, we're here to help. And if you're already an XTEND customer, we'd love to hear your story.

A Smarter Way to Heat Water
An element heats the water in your geyser. Traditional elements use coiled resistive wire, while XTEND elements use self-limiting PTC ceramic technology enclosed in a marine-grade stainless-steel or titanium casing.
This fundamental difference gives XTEND several advantages:
- Uses up to 25% less electricity
- Draws 1 kW less power while heating water at a similar rate
- Reduces limescale build-up, making it well suited to hard-water areas
- Reduces replacement and maintenance costs
- Works well with solar PV and battery systems due to its lower power draw
For the average family, the reduced energy consumption can save around 1,000 units of electricity per year.
Your geyser can effectively become an energy store for your solar PV system. Excess solar electricity can be used to heat your water during the day, while XTEND's lower power draw helps reduce demand on the grid or battery when heating is needed at night.
Whether you use grid electricity, solar PV or battery power, XTEND is designed to help you heat water more efficiently and reduce your long-term water-heating costs.

An element heats water in your geyser. Standard elements use coiled resistive wire covered by a soft metal coating. XTEND elements are fundamentally different. They use a self-limiting ceramic called PTC, protected by a marine-grade stainless-steel or titanium outer casing.
The properties of PTC, coupled with the design of XTEND elements reduce energy use by 25%. They also make XTEND elements hard-wearing and perfect for hard water problems. XTEND elements switch your geyser from a problem to an asset on a solar PV (photovoltaic – electricity) system due to the high efficiency and reduced power draw.
Saves the average family around 1000 units of electricity per year.
No matter where your geyser is located, XTEND elements can reduce your water heating costs. If you have a geyser, XTEND elements will save you money.
Rising electricity prices and recurring load-shedding have increased interest in energy efficiency, battery backup and generating your own electricity (Solar PV). How do XTEND elements help?
A geyser is expensive to heat. Installing solar thermal systems or heat pumps (connected directly to your geyser) is also expensive. XTEND elements are affordable and use 25% less electricity than a standard resistive element.
By reducing heat losses, XTEND elements heat water at a similar rate as traditional elements, including hard water and titanium elements, but use 1-2kW less power to do so.
This lower power requirement turns your geyser into an efficient, and manageable, energy store for solar PV. Spare electricity generated can heat your water for free.
XTEND elements will also use less grid or battery power at night if the water needs heating for the morning showers.
XTEND elements design and construction address many of the problems in hard water areas, including reducing the rate of scale build-up. This reduces the inconvenience and replacement costs of emergency element call-outs.
