HEAT DISTRIBUTION TEST

2kW PTC element vs 2kW Standard Spiral element
 

Arrow  AIM

This test was carried out to determine the final average temperature of water in the geyser using a fixed input energy amount (kWh) for various element types. The purpose of the test is to show that using the same amount of energy, a higher final average temperature can be reached using the Xtend range.

 

Arrow  METHODOLOGY

In this test scenario the following steps were followed:

1.  A 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 energy of 3.75 kWh.

4.  Once this target was reached the power supply to the geyser was shut down and the end time was recorded.

5.  The water was drained from the geyser and the average water temperature was recorded.

 

Arrow  RESULTS

The table below shows the percent energy saved when using a PTC Xtend element compared to a standard spiral element. This table shows that for the same energy input a higher final temperature can be reached with the PTC Xtend element.

 
 

Arrow  CONCLUSIONS

  • The 2kW Xtend PTC element saves 23% more energy when compared to its counterpart 2kW standard spiral element.
  • The Xtend PTC element manages to successfully produce a higher average temperature of water compared to the standard element of the same energy consumption.
  • The Xtend PTC element consistently produces an average water temperature that is close to the read on the probe measuring the water within the geyser. This confirms that the element heats more uniformly and consistently as opposed to its counterpart which produces heat layers within the geyser.
