Results

Summary “Overall, there was a 49.8% reduction in the mean gas units consumed over 6 days versus the 5 -day baseline period where the system was flushed and all other components were removed.”

Test Protocol
The boiler was on from 2200 to 0800 the following morning. Therefore, data for the 12th refers to the period from 2200 on the 11th until 0800 on the 12th. The average temperatures were determined from hourly readings taken in the garden of the property. These took into account the temperature from 0800 in the morning until 0700 the following day. So on the 12th of June the average temp is from 0800 on the 11th until 0700 on the 12th to better represent the background temperatures.

Note
The average outdoor temperature was around a degree cooler during the system test than the baseline.

Gas use difference: 2.0 = 49.8% reduction

The chart shows the time in hours from the start of the testing along the bottom axis. The blue line represents the outdoor temperature and the red lines the gas units used. A peak can be seen when the system starts at 2200.

From the left, there are 6 groups of gas use apparent over the full system test days. These are followed by a gap where the components of the system were removed and the baseline was then recorded over 5 periods. The red lines clearly illustrate more gas was used during the baseline.
