Just
two years after the first solar water heaters received the Energy Star
Label, they may loose it again. Right now, the Environmental Protection
Agency is revising the label's Water Heater Specification. It has found
that solar water heaters are not in line with the principle of the
Energy Star Label,
because they do not pay off quickly enough. The solar thermal industry
worries that loosing the label would result in a serious drawback
for the reputation of solar water heaters in the US. The final draft of
the specification is expected in January and the final version is going
to be published by February.
