This section contains theoretical information on the method used to optimise results with the QEnergySpa depending on the dilution factor. None of the information shown should be held as fact. All percentages used herein are based on a water temperature of 27.1°C.
Please note that although this document describes optimal levels, for practical purposes we recommend using as much or as little water as you feel comfortable with, at the temperature that you prefer.
The dilution factor is determined by aspects such as: percentage of body mass immersed in the water compared to the amount of water used. Therefore, the lower the ratio between immersed body mass and volume of water in the bath, the higher overall body energy absorption you will obtain from the QEnergySpa.
Any part of the body which is not submersed into the water, will be energised through the body part which is submersed. Therefore, the furthest point on the body away from the water, is energised to a lesser and delayed extent. This dilution factor is gradual across the entire body.
Where the dilution factor may become significant, would be in such instances where you wish to assist in recovery of an injury, whether new or old. In this instance, it is recommended that you immerse that particular body part into the water for maximum benefit. Caution: avoid immersing an open wound due to risk of infection.
Figure 1, BioEnergy Dilution Factor per body weight 
Figure 1  The diagram above indicates how the dilution factor decreases with more body weight immersed into the water with the QEnergySpa. Immersing your whole body gives you no dilution or a ratio factor of 1:1. Whereas, inserting ½ of your body equates to a ratio of 1:2 or ½ dilution at your opposite extremities. 
However, should you only insert your hands, then the dilution would become 1:83 at your opposite extremities. In short, in order to increase efficiency and the charge rate, we recommend that you maximise the percentage of your body mass in the water. 
The efficiency of the QEnergySpa is also dependent on the amount water in relation to the amount of body weight you immerse. The ideal water volume to body weight is a ratio of 3.5 litres of water per kilogram of body weight.
Table 1, below and the corresponding chart in Figure 2, indicate how much water is recommended for full body immersion in relation to your weight, based upon the 'ideal' ratio listed above. Figure 3 however, indicates the desirable water volume for partial body immersion (e.g. you feet or hands) or smaller body masses (e.g. infants and pets).

Table 1, Volume of water per body weight. 
Calculate
your ideal water volume in relation to 
Simply, the effectiveness would diminish, increasing the dilution factor.
For example, if you were to immerse one foot in 7 litres of water and your foot
weighed, say 2kg and your total body weight was 60kg, the dilution factor would be
1:30. That means that the BioEnergy efficiency would be one 30th less at the
opposite extremities of your body compared to the body part immersed.
Therefore, if you
weighed 120kg the dilution factor would be 60. If however, you were to immerse
both your feet into the water, weighing say, 4kg and you were using 7 litres of water,
your weight being 60kg, you would only have a dilution factor of 1:15 at
the furthest point away from the immersed body part.
