Don't know that that is a foregone conclusion. What were/are the
alternatives and relative fuel costs for the area you're in? The
installation cost sounds a little high, but for a high efficiency system
the long term cost should be significantly less than the
cheaper-initial-cost alternatives. How much is highly dependent on
local conditions.
