ok, so i've added an additional heater and things are working pretty good,
but still not up to my standards.
one of the variables is a tradeoff between temp and cfm. the original
blowers were 750 deg. units with about 45 cfm. the new blowers are 1000
deg. at 20 cfm.
here's the question: the heating elements in the old units are about 7
years old. does the efficiency of these heating elements (meaning sustained
temp) stay steady or would it decline significantly over time.
the reason for the question: it may be worthwhile to go back to the orginal
blowers but with new elements.
thanks for all those who have responded so far...
