or you would need to measure the dorp in temp.</FONT></DIV>

<DIV dir=ltr>Hey Lanny,
<DIV><BR></DIV>
<DIV>The thermal efficiency takes into account temperature of water and water
vaporized so as long as you take a temperature reading at the same time you
take the weight then it should not matter as the change in water vapor should
correspond to a drop in water temp.</DIV>
<DIV><BR></DIV>
<DIV>best,</DIV>
