submit you will never know how well anything works unless you compare it to the
usage. An electric resistance heater has such a low installed cost it can be
made to beat a solar system any time. All one has to do is shower once a
week. An electric resistance heater is an anethema to me but, right now, I
am in the process of installing a new one. One of the reasons for this is that I
could well be dead before a solar system is amortised.</SPAN></FONT></DIV>

<DIV>I don't agree. We can all reference a standard test procedure, but I'm
more interested in what people actually do. How much or how little electricity
and or hot water folks use in a day. At the end of the day it is the total
that matters, not the ratio (or at least that is how it looks to me).
