[QUOTE="Ampdog, post: 51895, member: 144"] No Gert, I was replying more to the immediate previous post by Windshear: 'One uses less energy by keeping the geaser hot' etc. Thus I agree with your previous post. Hi-Phibian asked That will depend on several other factors as well. I did take Thermodynamics 1 and 2 at Varsity (and hated it) but I am not the one to do this after all this time - if I ever was! Someone working in this field who can estimate several relevant factors could. But the simplified 'Conservation of Energy' principle does indicate that, overall, the greater the temperature difference between geyser and ambient, and for how long, the greater the loss. It is a 'time x temp difference' thing. If, say, all insulation was perfect and disregarding heater inefficiency, then you get out what you put in. Cold water added in bulk or over time; it needs so much energy to heat that water to a certain temperature - whether you put it in suddenly or over time. One can at least simplify it to that basic extent. After that, other variables start entering the scene, which might well over-shadow this basic principle. It then becomes a thesis. [/QUOTE]
