2kW Xtend PTC Element vs 2kW & 3kW Standard Spiral Element
Aim
This test was carried out to determine the percentage of energy saved when using an Xtend PTC Ceramic element compared to a standard resistive spiral element.
Methodology
In this test scenario the following steps were followed:
1. 150L B spec Kwikot geyser was fitted with the required heating element.
2. The geyser was filled with water from the mains, recording the ambient water temperature.
3. The geyser was heated to the target thermostat temperature, recording the kW used.
4. The water was drained from the geyser, and the average water temperature was recorded.
Results

Conclusions
- 31% more energy is required by a 3kW Standard Spiral element to achieve the same heating results as the Xtend 2kW PTC element.
- 34% more energy is required by a 2kW Standard Spiral element to achieve the same heating results as the Xtend 2kW PTC element.
- It takes the same amount of time to heat the water when comparing a 3kW standard spiral element and an Xtend 2kW PTC element.
