Heat IN or Out from the Vac tubes has been adjusted as follows:
Heat IN = Tube temp - Water temp - 4 (ºC)
The 4 degree is an adjustment for energy losses from poor insulation.

Removed -4 degree adjustment. It does not seem correct.

Power IN or out is calculated from temperature differentiation with respect to time and specific heat of water for 150 litres. P(W) = 4.186*150*0.998*dT/dt*(24*60*60).

Energy Use per 24hr is an estimate of Energy IN and out from Electricity, Solar, Used by hot water and Lost through insulation losses. These are calculated from Power IN/out which uses the mid temperature from the geyser.
